The Laser - History
The
Laser was launched to the public in 1971 at the New York
Boat Show. It was designed by Bruce Kirby with simplicity
and performance in mind, and quickly became the
quintessential one-design The Laser is sailed all over the
world, and there have been over 160,000***? Lasers built as
of May, 1998. There are currently builders in Rhode Island,
USA, **, England, here, and there **. At 13 feet 10.5 inches
long with a 12.5 foot waterline and 76 square feet of sail,
the Laser has enough power to glide in extremely light air
and blast along in a stiff breeze.
The Laser’s flush
deck, minimal beam (4.5 feet) and low freeboard (12 inches)
were designed to keep the hull weight to a minimum (average
130 lbs) and to allow simple car-topping and easy handling
on shore by women and junior sailors. The innovative "place
for your feet" cockpit means the boat ships very little
water, and comes up completely dry when righted after a
capsize. The Laser’s two-piece mast and sleeved sail are in
keeping with the goal of simplicity, and also help to make
car topping simple.
In the mid-80s***? the Laser
Radial Rig was developed and in 1988 the Laser Women’s World
Championship was sailed in the new Radial Rig for the first
time. The Radial mast uses the same top section as the "full
rig", and a shorter and more bendy bottom section. The sail
is 18% smaller (62 sq. feet) than the full rig, but the
center of effort of the sailplan is much lower. This means
the Radial rig generates more power relative to heeling
force than the full rig and so for lighter sailors allows
performance and handling far better than they can achieve
with the full rig. When it is quite windy, the Radial rig is
faster upwind!
The Laser Radial is unquestionably the
best training boat for Laser Olympic aspirants who are still
growing. In fact, the winner of the 1993 Radial World
Championship, Ben Ainsle from England, went on to win a
silver medal in the 1996 Olympics in the Laser. The Laser
Radial is also a great boat for Europe Dinghy sailors who
want to do as much close racing as possible. The Laser
Masters events are very well attended and enjoyed by keen
and competitive veterans of the class who have built
friendships around the world over the years of their Laser
sailing.
Recent rigging innovations make the Laser
easier and more enjoyable to sail, and better to race. One
used to have to stand up in the boat after the leeward mark
and jump down on the boom while taking the slack out of a
3-1 vang to get enough tension! Now, with an 8-1 slippery
spectra line swiveled vang, more than enough can be pulled
on from a hiking position. Tillers with rollers allow a helm
with great feel. Loops in the outhaul allow it also to be
adjusted while hiking.
Laser racing is arguably the
most competitive and close sailboat racing in the world.
Still, the real beauty of a Laser lies in its invitation to
go sailing for the pure joy of it. With no standing rigging
to bother with, no obstacle course of fittings to bruise and
cut, no cockpit full of water, the bare essentials of
tiller, mainsheet, and sailor can come together to feel the
magic of the wind and water cast its
spell.

Teaching Tip: Teach
self-coaching
The Laser, because it is a
light, high-performance singlehanded boat, is the perfect
place for sailors to really learn how to coach themselves
(see article by Hall, SW May ‘97). A common theme while you
are teaching Laser sailing should be "why, and how might
this apply to other boats?" Never pass up an opportunity to
teach more about steering with sails, or weight, or about
balancing the helm. Always encourage students to describe
what they FEEL when something is (or isn’t) happening for
them, the sensations in their hands, feet, butt, eyes, ears,
gut. The Laser teaches the fundamentals of sailing like no
other boat. The challenge is helping students learn to feel
and understand the lessons.

Boat Preparation
(See Bourdow
"Laser- from the experts) (text only)
Old
Boats
Very old boats need a few things done right
away. Replace the plastic cleats with aluminum ones on the
boom, cunningham, and traveler. Take the hiking strap off
and wrap it once around the plastic plate that holds it down
and screw it back in. Take the bailer off and make sure it
works properly. When re-installing or replacing, apply a
thick bead of silicone all the way around the inside lip of
the bailer so it is sealed to the hull and has maximum
suction.
End-for-end the mast sections. Drill out the
rivets holding the plastic pieces on/in. For the top
section, you should be able to get the bottom piece off and
then slide the collar off. To get the top piece out, put a
big screwdriver or wrench in the tube and stand it up
quickly. The tool will punch the cap out. Measure carefully
and put the collar on the other end. The plug at the end of
the bottom section is removed the same way, and the vang
tang and gooseneck are switched to the other end, being
careful to line them up well. When re-riveting the fittings,
be sure to use zinc chromate or ample silicone to prevent
corrosion. This job can be done quite quickly and will more
than double the life of the
spars.
Leaks
Leaks should be
tracked-down and fixed. Water in a boat makes it heavier,
harder to sail, gain weight over time, and weakens the hull
and deck. The soap-bubble & bike pump test is the best
way to locate a leak. First plug the breather hole under the
hiking strap. Apply suds to the deck at all fittings,
joints, etc. Hold the bike pump or a vacuum in reverse on
the stern plug hole and blow air into the boat. Where there
are bubbles, you found a leak!
Fittings may need new
silicone. If you can’t find the leak anywhere, it is usually
either the maststep, centerboard case, or hull-deck joint
where the bailer meets the cockpit. These should be fixed by
someone knowledgeable with resin and fiberglass work.
Another place some boats leak is the hull-deck joint under
the rails. A thin bead of resin should solve
this.
Boats with inspection ports tend to leak there.
Vaseline can help seal the threads. If the sailor uses the
port often, consider replacing it with a new one with a
fresh gasket.
The rudder
First
check that the rudder is as close to vertical as allowed (78
degrees) If not, file the rudder where it meets the pin of
the rudder head until it is right. The bolt which comes
supplied to hold the rudder blade in the head is way too
small. Get a 5/16" bolt and nylock nut and crank it pretty
tight, so you can just rotate the blade up for beach
launching. 1/8" Spectra is best for the downhaul, lead it up
over the top front cross pin and out the back of the tiller
slot, where it makes a 180 degree turn and comes forward
along the tiller with a purchase loop before the cleat.
Doing this keeps it from rubbing on the deck. For boats with
old tillers, make sure they fit tightly in the rudder head
by adding tape if necessary, and make sure they clear the
traveler cleat. Aluminum ones can be bent up slightly if
they don’t.
The tiller
The
length of the tiller does make a difference. For smaller
sailors, a tiller 1-3" longer than the end of the cockpit is
good, because a longer tiller means added leverage for
steering. The extension should reach to just short of the
middle of the daggerboard case. Be sure to check the
universal for nicks and cracking, and replace it before the
next regatta if it’s not solid. For bigger sailors, a
shorter tiller allows a longer extension and more travel of
the helm, but it causes more load on the steering arm when
there is helm.
The
daggerboard
Needs a rope handle, either
horizontal with two holes, or vertical with one hole in the
middle of the board and ¼" line twisted around itself then
taped together. The bungee should be ¼" and run all the way
to the bow eye on the starboard side, with lots of tension.
This is so the cunningham is easy to cleat while the board
is still up approaching the leeward mark on port tack. The
bungee is also an IMPORTANT SAFETY item that is often
neglected - it holds the board in during a capsize!! Make
sure it is tight enough.
(Back)
Rigging
The
mainsheet
Most top sailors use the metric size
between ¼" and 5/16", 10mm. Yale light or something similar
runs through the blocks nicely. 44’ with an eight knot 4"
from the end leaves a short tail to grab if it is let out to
the ratchet accidentally.
The new autoratchets are
great and really help the sheet go out for aggressive
downwind sailing. Mainsheet cleats are also good, especially
for getting the vang on. The little Ronstan minis aren’t too
painful to sit on and hold the sheet
well.
The vang
A swivel at the
base is necessary, ideally one with bearings that rotates
easily. Some swivels have ¼" pins, so the vang tang needs to
be drilled out to accept this. The other way to go is to get
bushing washers and use a standard 3/16" pin, so the vang
can be taken from boat to boat easily. The pin may bend a
little, so it is good to have a few spares. 3/16" Samson
spectra should be tied so when the bowline purchase hits the
block at max ease it causes a little tension on the boom.
This ensures a full range of travel. (If there is so much
slack that the vang is easy to hook into the boom, it won’t
be possible to get enough vang tension in breeze.) A
slip-knot loop handle is a must, and some people have a tail
after that to tie to the daggerboard so it can always be
reached. (see diagram)
The
outhaul
3/16" Samson spectra with two thimbles,
22’ a hitch around the long part (from cleat to mast)
included in the knot that holds the front thimble works
great to keep the whole thing up.
(Diagram)
The clew tie
Many
sailors are used to either a bolt-roped foot or an outhaul
car, something that makes the clew travel along the boom
without going up. It’s important to teach that the clew tie
effectively makes a track for the clew, and tying it snugly
to the boom is the hallmark of a careful job rigging. 1/8"
Samson spectra 30" Three laps around boom allows tying a
square knot tight enough. McLube the boom and tie down
before every race day so it slides
well.
The cunningham
3/16"
Samson spectra with two loops. There are diagrams with three
loops, but the added friction offsets the purchase gain. The
top bowline placement is critical for max travel.
(Diagram)
The traveler
3/16"
vectran, 9’. A large loop bowline that the line runs through
with a single hitch allows the loop to be pulled very tight
and is relatively easy to unrig.
(Diagram)
Hiking strap
May need
to be shortened so there is room for enough adjustment. A
10-12" between the aft edge of the cockpit and the strap is
good.
Strap bungee 1/8", about 2’
depending on strap. Makes a loop through strap and under
traveler behind cleat. A square knot will eventually come
undone. Tie overhand knots in each tail and push them tight
against the square knot.
Strap Adjuster 6’
of 3/16" pre-stretch (spectra is too slippery), looped
around and back. (See
diagram)
Battens Those little ends like to
come off and get stuck in the sail. Glue them
on
Tell tales Three sets - one for upwind
near the luff, one in the middle of the top 1/3 of the sail,
and one for by the lee two feet in from the leach. Light
yarn works nicely because it isn’t too jumpy.
Wind
Vane A windvane or long yarn in front of the mast is
great for light air when it’s shifty and for learning angles
downwind.
(Back)
Rigging Up
Rigging the
Laser A Laser sail flapping in the wind is getting
old quickly. The batten pockets are screaming, the cloth is
deteriorating, and the stitching is strained. When possible,
the sail should go up only when ready to go sailing, and
should come down when the boat won’t be sailed for a
while.
The hardest place to rig is with the boat
already in the water.
- Check stern plug!
- Launch
- Daggerboard in, but not bungee on yet
- it will be in the way of the mast step
- Tiller into rudderhead and tied
before getting on boat. This reduces chance of losing
rudder while putting it into the gudgeons. Rudder
on
- Mainsheet rigged completely through
boom
- Outhaul through boom cleat and back
eye with tail free and ready, and purchase loop laid out
on deck around maststep
- Mast together - a wrap or two of
packing tape so the pieces fit tightly is good. The rivet
should be pointed directly back. Get the collar just
started in the bottom section and stand the mast up. Lift
it and lightly tap it down on the ground. The weight of
the top section will push it into the bottom section with
a few taps. If the mast has a permanent bend, DO NOT
STRAIGHTEN IT, flip the ends (see setting up the
Laser)
- Sail on mast, battens in, vang pinned
on
Rigging Tip - put pin through from port to starboard
so the last part of the cunningham doesn’t catch on the
ring-ding.
- Rig cunningham
- Step mast - if there are many boats
in the water side by side so the boat can’t be pulled
along the dock, this is a two person job: one person is on
boat behind mast step on knees to hold mast butt in place
and help pull mast up, while other person walks mast
upright and steps on bow pushing mast up.
- Rig the tail of the cunningham
through the eye and cleat immediately and pull a little
tension on. This helps keep the sail from twisting on the
mast, and ensures that in the unlikely event of a water
landing the mast doesn’t come partially out and destroy
the maststep. Make sure the bowline handle tied in the
tail of the cunningham only allows enough slack for the
luff tension to be released and no more. IF THE BOAT
CAPSIZES WITHOUT ENOUGH CUNNINGHAM AND THE MAST COMES OUT
A LITTLE WHILE RIGHTING, THE MASTSTEP TUBE WILL
BREAK.
- Most people put the boom on the
gooseneck pin, then try to catch the flapping clew and rig
the outhaul while standing on the poopdeck. It likes to
fall off that little pin, and having it on makes the sail
want to fill, compromising balance. Instead, stand in the
cockpit and bring the end of the boom forward so it
reaches the sail easily without it filling. Rig the
outhaul set at max ease, and rig the clew tie down. Then
push the boom back and put it on the pin, being careful to
get the parts of the cunningham around or on one side of
the gooseneck properly.
- Hold boom down and put vang key in
boom. On the way off the boat, tie the board bungee to the
bow eye - YOU’RE DONE!
Rigging on dolly, dock, beach, or
grass
- Begin with step 6, do not rig
mainsheet
- When rig is up with cunningham and
outhaul on, rig mainsheet backwards through ratchet, front
boom block, eyestrap, and back block. Tie a slip-knot. Now
the sail can rotate in front of the boat if necessary, but
the sailor can sheet in from the ratchet to get the boom
around the parked camels and other obstacles in the
boatpark.
- Daggerboard is placed with the top
forward edge in the aft bottom corner of the cockpit. This
prevents the tip from breaking when the bow is lifted for
launch - a very good habit
- If the boat will be launched down a
ramp, rig the tiller and rudder together tied down, and
place rudder blade under traveler, with tiller pointed
forward and traveler tight. Slide rudder back until nut on
rudder head is held forward by traveler. If wind allows,
finish rigging mainsheet. Wheel boat down ramp and when
transom reaches end, turn boat 45 degrees and put one foot
against dolly wheel, reach back and drop rudder
in.
- If the edge of the ramp is well
carpeted, the bow can bet set down off the dolly and the
board dropped in too, and the bungee can even be tied. If
not, the bow is set in the water and the boat turned
sideways to the ramp to put the board in. If the wind is
blowing away from the ramp, the advanced technique is to
simply step on and push off, putting the board in while
floating away from ramp. It’s important to stress that
efficiency and etiquette on the ramp will earn respect and
help prevent congestion.
- If the boat will be launched
from a shallow beach with the wind offshore, leave the
mainsheet as is (with slipknot) and put the rudder in the
gudgeons with the blade up (the bolt should be big and
tight enough that it stays up). Wheel the boat backwards
into the water and slide off dolly, push rudder down a
little and step on to drift away from beach with boom out
in front of boat. Put blade in when deep enough and when
clear push rudder down and go head to wind to finish
rigging mainsheet.
- The most difficult launch is
off a shallow beach with the wind onshore. This often
means there are waves to contend with, and one has to sail
upwind with very little blade or rudder in the water.
Wheel the boat along the beach to begin on the lifted tack
away from beach if there is limited area to the side (a
pier, breakwall, moorings, etc.) Rig the mainsheet
completely, and put the boat just off head to wind on the
correct tack. Put the daggerboard in and tie the bungee to
hold it up. Put the rudder down just below horizontal.
Wheel the boat into the water bow first, being careful to
keep it just slightly off the wind so the boom doesn’t hit
the board. When the boat is floating, turn the front of
the dolly into the wind and slide the boat forward off the
dolly. It helps to have someone hold the dolly back as the
boat is slid forward. Push the board and rudder down as
far as possible, step in and balance well since there’s
not a lot of rudder in the water.
Returning to shore
- The most difficult condition is again
an onshore breeze. The rudder downhaul is undone and a
check that the rudder will kick up is performed. The 8
knot in the becket tail of the mainsheet is untied while
still well away from the beach or dock. The mainsheet is
unstrung from the traveler block, but that tail is held in
the mainsheet hand along with the sheet from the ratchet.
This allows the boom to be sheeted in for a moment if
necessary. (If it becomes necessary to beat again, simply
tie a slip knot in the tail, let go, and sheet from the
ratchet.) When boat is lined up upwind of landing place,
let tail go and pull mainsheet through ratchet all the way
out of boom. The boom will rotate in front of the boat,
and allow a slow approach to the beach or dock. Lift
daggerboard out completely, reach back and kick rudder
almost all the way up, and turn boat sideways to beach.
Get out on WINDWARD side. If approaching a dock, the
blades can be left down until after the turn, when pulling
the daggerboard up will help the boat slide gently to the
dock.
(Back)
It’s REALLY Windy
There
are a few ways to go sailing on a really breezy day. One is
to reef the sail. Take the top batten out, wrap the sail two
or three times tightly and neatly around the mast, and rig
up. A special 12’ outhaul line, which allows 2-1 and then
reaches the cleat without the purchase is best. It needs to
be pulled quite tight, but won’t be adjusted. The cunningham
should be pulled very tight, and the daggerboard can be left
up a little to balance the helm. Another way is to put two
people on the boat, with one doing the tiller and the other
the sheet. Remind sailors not to let the boom out too far
downwind, and not to gybe because it can be hard to duck at
just the right time with two people. Have a towline tied to
the mast and coiled, just in case. The only way to get
comfortable in the big breeze is to go do it, so don’t let
those days go wasted!!!
(Back)
BOATHANDLING
Basic
Posture
The tiller is held like a microphone
overhand, and the mainsheet taken directly from the ratchet
in all but light air running. Sit facing perpendicular to
direction of boat, with feet and legs together. This basic
"stance" is appropriate for all points of sail in nearly all
conditions. Exceptions are moving forward in light air or
moving back in very heavy air. Learning to sail fast
downwind requires being comfortable in this position, i.e.
not putting a knee down in the cockpit when sailing by the
lee. This allows greater mobility and feel, and requires
that the boat be sailed balanced, whereas putting a knee
down makes it possible to sail in a stabilized but less
efficient manner.
Coaching Tip: The knee-down habit
is very hard to unlearn, and if it can be pre-empted by
emphasizing the benefits of good body positioning, the
sailor will be way ahead in the long
run.
Sheeting in
With 44’ of
mainsheet, the ability to sheet in effectively is one of the
most crucial fundamental skills of Laser sailing. The idea
is to use as few pulls as possible, which means using both
hands. The front hand sheets a big pull toward the stern
while the tiller hand reaches forward to grab and pull up
and back (while holding extension) while front hand reloads,
repeat… This skill is used to round the leeward mark, during
starting, during puffy conditions, during 720s, and is handy
in almost all boats with a tiller and mainsheet. It’s
important to teach sailors to use both hands, to be
comfortable with the mainsheet in their tiller hand, to be
able to steer while holding mainsheet in tiller hand, and to
use big pulls.
Bearing
off
Sailing Tip - before the weather mark, run
the mainsheet to be sure there are no knots.
Easing
sheet involves simply letting it run through the fingers.
However, at the top mark an arm’s length over the head in
preparation ensures that the first five feet go out
precisely. When it’s windy, the boat won’t bear off if it
isn’t flat or if the mainsheet isn’t going out enough. Hike,
hike, hike! The ability to get right down to a run and hook
into a good wave is worth a lot of
distance.
Drill: (Advanced). Round the weather
mark and bear away right into a gybe , without stopping the
turn. This is actually easier in some respects than carving
hard down to a run and stopping the turn without gybing or
deathrolling, and is a great skill to
have.
Tacking
The Laser tiller
extension is long, and will only fit past the mainsheet if
it is "pushed through" exactly the right way. There are two
styles of tack, the difference being when the hands are
switched. Both begin by taking back foot out of strap and
placing it over the top of the strap
Learning: Tiller
is pushed to leeward, tiller extension is pushed through
upper corner by mainsheet block, sailor goes to balls of
feet facing forward (straddling strap) and continues through
boat while rotating hips to new position. Tiller is held
outboard and behind body and hips stay in front of tiller
while they rotate. Hands are not switched, so sailor is now
steering behind his back with front arm, holding mainsheet
across lap in back hand. Back hand with mainsheet grabs
tiller, then front hand takes sheet. It is possible to
flatten after a roll tack or to hike when breezy in this
configuration, and it allows the sailor to focus on his turn
and on keeping the boat flat with proper sheet tension at
end of tack. It is also the way he will come out of a
heavy-air gybe, and so it’s worth getting used to sailing
the boat that way.
Drill: Sail a whole beat
without switching hands
Advanced: Once the
tacking is comfortable, the goal is to become more effective
with weight movement. The only way to do this is to make the
tiller/sheet hand switch during the tack, while moving
through the boat. This requires more dynamic body movement,
to be far enough forward to allow hands behind back to do
their thing. This "switch on the fly" is a skill which will
be carried to most boats, and is especially important for
great college dinghy roll tacks.
Drill: A
great way to practice the switch is in little or no wind,
doing continuous roll-gybes, switching every
time.
When roll tacking, a big roll with a
big ease just before flattening is best. As the wind comes
up, the boat can be rolled less. As the chop gets steeper,
too much roll is ineffective because the boat slaps the
waves while being flattened. When it’s breezy, it’s key to
come out of the tack dead flat, so the right ease into and
out of the tack become critical.
Light air
The
big roll: moving butt out and back along deck by pushing
with feet off side of cockpit helps the bow out of the water
and around and begins the initial roll. Next is the big
lean, and the smaller the sailor, the more aggressive she
will need to be to roll hard enough. Sheeting in all the way
at this time gives something on which to pull oneself back
into boat, and helps load the mast to spring straight and
cause the mainsheet to go out more than it would on its own.
The roll tacker can grab the close handrail, the hiking
strap, or the far handrail, whichever is most comfortable
for her body size. The ability to launch herself uphill to
the new high side makes or breaks the tack, and requires a
coordinated combination of arm pulling and legs pushing. The
goal should be to land with the butt past the side of the
boat, over the rail, hands already switched and mainsheet
quite eased (2-4 feet) The roll is too hard or the flatten
to slow or the sheet too tight when the tiller must be
pulled to weather to make the boat go straight out of the
tack.
Heavy air.
The goal here
is to be hiking on one tack, then hiking on the new tack,
with no time in between. This requires hiking as long as
possible at beginning of turn, leaping across to have (old
back) new front foot catch the strap as sail fills. The
lower the shoulders are kept, the less movement is wasted.
It may be necessary to ease a little sheet as the sailor
comes out of the hike to keep the boat absolutely flat, and
to ease even more to ensure that the boat tracks forward
after tack. These things take time to develop, but should be
secondary to the goal of hiking as long as possible into
turn and then as soon as possible out of
turn
Drill: The object is to get comfortable
hiking as long as possible into turn. Head up while hiking
as in the beginning of a tack. At last possible moment
"leap/bounce up/get" butt onto deck. The idea is to wait as
long as possible, and to get in as quickly as possible. The
boat may get stuck in irons, that’s ok. Bear off and repeat.
Sailors will be surprised how far into the wind they can
turn before the boat comes over on top of them. This is
because while the sail is depowering, the actual turn is
causing the boat to want to heel to the outside of the turn
(to leeward)
Medium air
These
tacks involve blending aspects of light and heavy air to
achieve the right amount of hike, roll, ease, and
hike.
Coaching Tip: Medium air tacks are a great
place to teach sailors to be aware of the feedback
mechanisms available to them, and how to make adjustments
based on this input:
Lots of weather helm out of tack
- means flatten sooner, roll less, or ease more
No
speed out of tack - roll harder, come out lower, or
both
Lee helm out of tack - sheet going out too far,
or boat being
overflattened
Gybing
Gybing
a Laser takes a trick flick of the wrist, to keep the
mainsheet from looping around the back corner of the boat
when it goes slack as the boom comes across. This is true
for a light-air roll gybe and a heavy-air planing
gybe.
Light air
Reach to reach
- Put the daggerboard all the way down, start turn with
weight, letting the tiller follow the turn. Roll late enough
that max roll occurs just before boat gets to new course.
Flick and flatten.
During learning stages, switch
hands after flatten as in tack, with goal of eventually
switching while crossing boat.
There are two methods
of run to run gybe in light to medium air:
- Sheet in quickly so boom comes across
with as little turn as possible, and come out on a broad
reach. It’s necessary to turn quite far or sheet in a lot
or both, and then the boom needs to be pushed out again.
Boat comes out of gybe with great speed.
- Grab both parts of the mainsheet from
the back and throw the boom across, maintaining course
(some face forward, some backward). Major pro to this
style is being able to continue straight down the course.
However, the roll is not quite as aggressive. These gybes
are consistent and reliable. Other style would be used if
a course change (to get to a puff or protect a lane) were
called for anyway.
Heavy air
Reach to
reach - more speed means less apparent wind and an easier
gybe. Being on a wave is best! It’s key to have the board ½
way up so the boat doesn’t trip on it. Start turn down with
the boat dead flat by easing sheet. Keep boat turning and
flat, as leech flickers give a BIG TUG on sheet, then while
crossing boat flick by simply placing hand in path of
mainsheet near front boom block to "bump" it as it comes
across. As boom comes across, turn back down the other way
("S turn") to help boat accelerate and reduce angle of
apparent wind, reducing healing moment. Most important is to
hit new side with weight before sail
fills.
Teaching Tip: Make an analogy: Gybing
in heavy air is like catching an egg. Winning the egg toss
means giving with the hands in the direction of the egg as
it is caught. Catching the wind on the new gybe without
capsizing requires reversing the turn to aim the boat more
with the wind so it accelerates and the boat and rig can
give as the sail fills - instead of the force of the wind
pushing the boat over to leeward.
Run to run
- These gybes are very challenging to do well in a Laser,
because they require sheeting in a few feet quickly so the
boom comes across. This adds load and makes the boat want to
head up, so weight is critical to balance this force so the
boat doesn’t slow down or head up out of the turn. A little
extra steering may be necessary, but once the boom starts
coming across the gybe is like the reach to reach. These are
perhaps the hardest maneuver in the Laser, but are essential
for success racing in the breeze.
Mastering
the move in a Radial rig can help even big sailors get
better at the full rig gybe. Also, because the sailor must
be so far back in the boat, it is difficult to switch hands
behind the back while crossing boat. Trying to switch hands
may also compromise the quality of the s-turn, so steering
behind the back is done until things settle down and a
switch is possible.
720 The 720 is
about putting together a tack, bear-away, gybe, head up,
tack…
There are two ways. As long as the sailor is
able to bear away, it is best NOT to switch hands after the
tack. Instead, the sailor should steer behind her back after
the tack, so that coming out of the gybe she is ready to
begin hiking and trimming in right away and can also steer
precisely. This is the most critical part of the turn, so it
is good to be ready to sheet in and hike.
In really
heavy air, it may be necessary to tack and gybe normally,
switching hands. The big challenge then becomes switching
hands again after the gybe and starting to sheet
in.
Teaching Tip: The way to learn 720s is to break
the 360 in half: tack and bear away, get settled, then gybe
and head up to a beat, gradually reducing the "get settled"
time to nothing.

ADJUSTING CONTROLS
The
vang
Mainsheet cleats are most useful for getting
vang on. When sailing upwind, sheet in block to block and
cleat mainsheet. With back foot push boom to leeward and
down, hard. This bends the boom temporarily. With front
hand, pull vang. The length of the tail and loop is very
important. Too far back, and the sailor can’t use his body
and shoulders to pull, only his bent arm. Too far forward
and it’s hard to reach from a hiking position. At max ease,
there should be about 14" of line between the "hand" end of
the loop and the vang cleat. This length depends a little on
the sailor, but this is a personal fine-tune adjustment
worth making.
Easing vang: Marks on the vang are
helpful for reproducing settings while already going
downwind. The best time to ease the vang though is before
the weather mark. The distance between the boom blocks in
back (amount of sheet showing) is a good gauge. The range
will be from boom eased up to horizontal, to blocks only a
few inches apart. From a full hike, ease sheet to desired
setting, cleat and then pop vang off to let slack out and
recleat line firmly when it won’t go out further. With
practice this can be done very quickly and
accurately.
Cunningham Should also be
eased before weather mark. Right after easing vang, uncleat
and toss line forward of cleat so it doesn’t want to
recleat. Reach forward and pull the one part that pulls all
the others loose. If the cunningham is rigged with this part
to starboard and it is marked with a marker, it is easy to
find.
It’s best to get it back on before leeward
mark, but this is not always possible. In that case, a quick
luff head to wind and a big pull using the legs against the
front of the cockpit works well. It takes practice to do
this effectively, but it is far better to give up a length
performing the maneuver than to sail a whole beat tipped
over with not enough cunno. As with the vang, the position
of the loop handle is critical. If there is too much slack
in the system, the sailor will reach the end of her pull
with legs extended before the grommet gets to the gooseneck.
Keep reducing slack until the bowline at the cleat almost
causes tension in the luff.
Drill: Vang & cunno
off, bear away to run. Sheet in up to a beat, vang on, cunno
on, repeat - both tacks
Outhaul If the
outhaul is rigged well, it should be easy to pull on while
hiking. To ease, first grab the last part in front of the
cleat and pull slack into the system. Sharply lift line out
of cleat and let it out. It will be necessary to ease
mainsheet a bit to keep the boat upright while doing this,
and some top sailors with shorter arms actually stand up in
the boat to have leverage and reach the
thing.
Strap The strap is a critical
control which tends to be neglected, even by some top
sailors. A major aspect of downwind speed in the waves is
the ability to be connected to the boat and to help direct
it with feet, legs, and butt. The only way to do this on
reaches is with a tight strap. When it’s super windy, it’s
actually best to get the strap tight before the weather
mark, and loosened again after rounding the leeward mark. In
more moderate conditions, it can be tightened after the
weather mark and loosened before the leeward
mark.
Board The board is another
control which should be done before the weather mark and
after the leeward mark when it’s super windy. Otherwise, as
with the strap, after the top mark and before the leeward
mark is fine.

The Rig &
Sail
Understanding the Laser
Rig
The mainsheet
The Laser
mainsheet controls the angle of the boom until it is pulled
over the corner of the boat, at which time it begins to also
control mast bend. This is different from a stayed mast, on
which the mainsheet controls leech tension but does not bend
the mast enough to dramatically ALT=''er sailshape. As a
result, as the Laser mainsheet is pulled tighter, bending
the mast and flattening the sail, it reduces leech/batten
hook or "return" and opens the leach. It is paradoxical that
we call the Laser leech "open" when the cloth along the
leech is pulled tightest (at max bend). This is opposite to
a stayed mast, where a tighter mainsheet means a tighter
leech means more hook. This is an extremely important thing
to teach about the Laser rig and sail.
Conversely,
easing the Laser mainsheet makes the sail fuller, causing
more return in the leech and adding power. Again, this is
opposite to a stayed mast, where easing the mainsheet opens
the leech by twist, and reduces power (unless it is very
light in which case power comes from flow)
A result
of this situation is that we often find sailors
"two-blocked", thinking that gives max power (tightest
leech), when they should be eased one to two feet on the
sheet to straighten the mast and make the sail fuller. The
Finn and Europe dinghy masts, which are extremely tapered at
the top, are very sensitive to sheet tension because of what
it does to the top of the sail. It is possible to begin to
develop this sensitivity in the Laser, though it is often
overlooked.
Drill: Set up a boat on a dolly when
there is some wind, with one person holding it flat. Have
sailors stand behind the boat with the mainsheet, and sheet
in. Have them describe what they see happening to the mast,
fullness, shape, and "exit" of the
sail
By-the-lee: a whole new thing The
other difference between the unstayed and stayed rigs is the
ability to sail by-the-lee. This may come naturally to
Optimist sailors, but anyone else is likely to be baffled
about it for a time. First, the physics: the analogy to draw
is with "heating up" downwind in a spinnaker boat to
generate more apparent wind and achieve better VMG. This
works because when dead downwind there is little flow over
the sails - the boat is literally being "pushed" by the
wind, with no wing-like action going on. Broad reaching in a
Laser isn’t very effective, but sailing by the lee
definitely is. The goal is to reverse the flow on the sail
from the normal direction to a leech to luff direction. This
achieves a few things:
- The knife-edge entry of the leech
gives the sail very undisturbed air, which stays attached
for longer than a comparable angle of attack flowing first
around the circular mast
- When the sailplan is heeled to
windward, by the lee flow encounters a "swept-back leading
edge". This swept-back edge develops "roll-over vortices"
which help keep flow attached abnormally long, not unlike
the Concorde’s swept-back delta wings (See Bethwaite,
High Performance Sailing,
pp.365,366)
- The boat balances nicely when sailed
by the lee heeled to windward. Reverse flow can actually
be achieved with the mainsheet in from perpendicular,
allowing a course closer to dead downwind and therefore
great VMG

Article: Adams/Adamson "Zig-Zag Downwind"
Pop quiz:
Should you sail lifts or headers downwind if sailing
by-the-lee???
Answer - lifts!!!
Drill: Have
students sail down the lawn with an arm out perpendicular to
be the sail. Make sure they are sailing to get reverse flow
(hand pointed closer to wind than shoulder), with the run
square. Shift the wind until now they are sailing directly
at the mark. Is this shift to the right or left, and would
it be a lift or header if they were on the same tack going
upwind?
(Back)
Tuning
The Laser sail can
be anything from very full to extremely flat. There are two
main ways to set the sail up.
- By look with "measurement tuning
guidelines" in mind
- By feel, with the helm, relative
speed, and boat behavior in mind
It is best to start with method #1, but
to begin developing proficiency at "symptom tuning" through
method #2 as soon as
possible
UPWIND
Cunningham Think
of the cunningham as a wrinkle remover until it gets windy.
When the mast is bent, overbend wrinkles appear along the
luff, and run especially from the mast joint to the clew.
This can cause the sail to "hinge" along these wrinkles and
look particularly bad. Pulling cunningham on smoothes out
the front of the sail and pulls the draft back where it
belongs. When it gets really windy, more cunningham opens
the leech at the top, depowering the sail further. It is not
unreasonable to pull the tack grommet down past the top of
the gooseneck in big breeze. To do this, the cunno must be
rigged on one side of the boom.
- article by Ron
Rosenberg circa June 1993? With pictures of Laser rig from
behind
The Vang
Super-light - sheet
block to block and take slack out. Some vang tension is
necessary to keep the leech from hooking too
much
Light - as long as there is enough wind to
ensure good flow (4-5 knots or more), the vang is set for
roll-tacking. With mainsheet blocks about 1’ apart take out
slack
Medium - until overpowered, vang is set for
tacking. Blocks a touch looser than two-blocked, take out
slack
Windy- Pulling the vang on bends the mast and
flattens the sail, just as the mainsheet does. However, when
the mainsheet is eased without vang, the boom goes up and
the sail gets fuller. With the vang on hard, easing the
mainsheet moves the boom to leeward without letting it up,
just as dropping the traveler does on a big boat. A very
tight vang becomes critical when it is necessary to depower
by easing mainsheet. (Review technique for getting it
on)
Other Thoughts In flat water, err
toward more vang less cunningham. When the water is flat,
steering is very effective to help keep the boat flat.
"Feathering" depowers the sail, and the boat keeps moving
through the water. Having a tight vang and not too much
cunningham keeps the entry flat, and means the front of the
sail breaks evenly from bottom to top. With good mainsheet
trim and good steering, the sail is very
efficient.
In chop, err toward more cunningham, less
vang. It isn’t possible to control power in the rig by
feathering in chop, because the boat stops dead in the
water. Also, as the boat pitches up and down, a sail with
even twist will either be trimmed perfectly, or it will be
all wrong at once. It is better to have some twist, and for
the top of the sail to open as the boat is hiked down over
the top of waves. This means lots of cunningham. To have
enough power in the lulls and troughs, the vang then needs
to be a little looser.
Drill: With Laser rigged on
dolly, some wind in the sail, and someone holding the boat
flat, look at both of these settings. Which shape goes with
which condition? In flat water a constant angle of attack
from tack to head is good, because the whole sail is
"looking at" the same breeze. In chop, some twist, so that
at least part of the sail is always working properly, is
better than a constant angle of attack bottom to top, in
which case the sail is either "all right or all
wrong".
Finally, when the boat is always overpowered,
the cunningham is maxed and the vang is cranked, so the
mainsheet can be eased at the top of the waves to keep speed
up. When it’s super windy, the sheet is left out 2-12", and
the sheeting in and out done from that
trim.
Outhaul A great "ballpark",
all-around setting for the outhaul is to have the foot four
to eight inches from the boom at its deepest point. The
distance from one’s thumb to pinkie if they are spread apart
to make the Hawaiian "Hang loose dude" sign will get most
sailors close. It will even help calibrate the method
appropriately for body size. The outhaul is perhaps the
easiest (besides mainsheet or board) control to adjust by
feel. If there’s lots of helm upwind or on tighter reaches,
or if the boat is really hard to steer (same thing sort of)
it’s too loose. If the boat seems to lack power and the
cunningham and vang are correct, especially in choppier
conditions, it’s too tight. Downwind it may seem tempting to
ease it way off. In fact, too full a sail is worse than too
flat a sail on a run because the flow has a hard time
getting around hooked battens. The condition for the loosest
outhaul would be broad-reaching in 10-14 knots &
chop.
Caution: One mistake sailors make is to pull
the outhaul too hard when it is really windy. Too much
outhaul causes the exit of the bottom leech to be too open
and creates a block for the air trying to exit the leech on
the leeward side. Easing just a little (an inch or two at
the cleat from max tight) will leave some shape in the sail
and make the bottom exit more parallel to the wind when the
sail is eased during vang
sheeting.
Strap The hiking strap is an
often-neglected, but critical control on the Laser. It is by
no means "set it and forget it". The most common error is
too loose. An effort to hike way out with a loose strap is
valiant but can be ineffective. Far better to have a tight
enough strap that true straight legging is possible, with
the goal to get the shoulders as far from the rail as
possible and down to horizontal. A loose strap makes this
difficult physically, and has the added drawback of reducing
the sailor’s "connectivity" to the boat. On hiking reaches,
a bone-tight strap is
essential.
Board The board should be
all the way down upwind except for small sailors who are
very overpowered, or Radial sailors when it is very
windy.
Symptom Tuning
Heavy
helm, good pointing but no "forward mode" - try more
outhaul, then more vang
Good forward, but no "height
mode" - try less cunningham, then less vang
Neither
mode - if sail is already full and it’s not super windy try
HIKING HARDER. If it’s windy and sail is already completely
depowered, with max vang, try easing mainsheet a few inches
and sailing lower but much faster.
Coaching tip:
Though counter-intuitive, footing is often the best move for
lighter sailors when it’s choppy, since pinching to depower
stops the boat and it slips sideways, meaning no speed or
height. This requires a VERY TIGHT VANG
however.
DOWNWIND
Except on
overpowered reaches, the cunningham should be all the way
off downwind.
Half cunningham can be left on for very
windy runs to depower, but some must be
eased.
Caution: Having the cunningham on all the way
on makes the top so open that the sail is pushing sideways
into a deathroll up there. This is bad.
Vang
adjustment and board height are most critical. Most Laser
sailors go downwind with too much vang. In a stayed rig, a
snug vang means the leech doesn’t spill off to leeward and
give up power. On the Laser, the vang should be eased until
the mast comes straight or very nearly so. This gives the
fullest sail, with the added and important benefit of making
the leach "lively". As the boat goes through chop it opens
and fans on its own from the mast bending. This activity is
fast on reaches and especially on runs. The vang is too
loose when the sail opens in a puff or chop and "never comes
back" A tight vang has other drawbacks. On windy reaches, it
makes the boom hit the water sooner and makes the mainsheet
trim hyper-critical.
The one time a tighter than
normal vang can be good is very windy runs, when it is
undesirable to have the top of the sail more open than the
bottom, or unstable, as both of these cause a heeling moment
to windward and promote the death
roll.
Teaching Tip: Have sailors pair up and
help each other get the vang right downwind. One sailor
sails to where she can see the leech well, and the other
plays with the vang. The goal is a leech that opens when the
sail is pumped, but "comes back". Have the sailor-coach
describe the leech action to her partner as "dead, lively,
or floppy" or something similar. Dead means ease vang,
floppy means tighten it.
The board is set
highest on windy, hiking, planing reaches, and light air
runs. Having the board high on these reaches reduces helm
and makes the goal of a constant angle of heel more
obtainable. For best control and speed on the run, the board
should be about half way down. The board is a feel thing:
too high and the boat wants to "dish-out" instead of
tracking. Too low and the boat trips and gets sticky.
Inexperienced sailors tend to leave the board down for windy
runs. This makes things much harder than pulling it up half
way!!

reward great technique. The Laser will help a sailor develop
technique and feel that will make him better in any other

EXTRAS
A Few
Tricks
When it’s windy and bailer will be left
open: remove plug and tuck it under grab rail. This helps
prevent kicking it closed
Bailing water out of
cockpit: slide foot quickly along cockpit floor all the way
to back, kicking water out
Righting a capsize with
rig upwind of boat: the boat will want to blow back over.
Either climb in and leap to high side, as soon as rig
catches wind, or as boat comes up hang onto board and roll
under boat as rig blows over, then right boat ("California
Roll")
To get out of irons: pull boom way to windward
and push tiller to leeward. This works great before the
start if sculling the bow down isn’t working
Clearing
weeds off the rudder sailing upwind: first do board, then
heel way over and as rudder comes out of the water and
vigorously shake it back and forth. This will sweep the
weeds down the leading edge and off
A
Couple Fun Things
Back flip: When there’s no
wind, see who can stand on the stern and pull the boat
directly backwards on top of themselves with the mainsheet.
The winner is the one with the bow the straightest up in the
air
Hang time: On a run, see who can sail on the edge
of a deathroll the longest, touching the board under the
boat by reaching over the rail
Stuff the bow: when
there’s wind and some chop, see who can get the stern
farthest in the air
Standing tacks: tack standing up,
either running around the mast or stepping over the
boom
Standing gybes: Gybe standing on the stern, the
boom swinging in front of the sailor (careful!)
Climb
the mast: A prize for anyone who can touch the mast tip
before it reaches the water
All
Sorts of Drills
- Follow the leader: a great one for
beginning and veteran Laser sailors alike. Even motor
downwind really slowly and get them to stop. Also let each
of them lead without a motorboat to follow. Follow the
leader is a great way to do a gybing drill if you have a
good coach boat.
- Start/stop
- Tack/gybe on the whistle
- 720s
- Cone drill
- Sail backwards
- Sail standing up
- Sail with a piece of bungee holding
tiller near centerline
- Sail downwind with board all the way
up
- Sail downwind with feet off the floor
(knees up)
- Sail downwind with rudder up half way
- be sure to tell them that the idea is NOT to use the
loaded rudder to go straight. In fact, this is a drill for
advanced sailors only, since pushing too hard on a kicked
up rudder will stress the pintles and tiller. For solid
sailors, it gives loud balance feedback to have the
exaggerated helm, and will encourage better weight
movement and sailtrim. Do this for a short time only, with
100% focus.
- Sail with no tiller extension. This
reduces the ability to move weight, and emphasizes
sailtrim
- Capsize and right boat as fast as
possible, especially on runs
- Round weather mark and continue turn
right into a gybe
- Vang off, bearaway
- Sheet in/head up, vang on
- Vang off, cunningham off, bear
away
- Cunningham on, sheet in/head up, vang
on
- Cunningham on while sailing
upwind
- Outhaul on/off while sailing
upwind
- Two gybes on a wave
- Take mainsheet completely out of
ratchet and sail as far by the lee as possible
- Deathroll contest
- Keep bow near a buoy for as long as
possible
Gear
The two most
important personal-gear items are a well fitting and comfy
lifejacket, and good hiking wetsuit-pants. Wearing lycra
shorts over the top of hiking pants will greatly prolong
their life by protecting the butt. There are a few brands of
hiking pants, and they can fit a little differently, so it’s
worth trying different ones on. Boots are a matter of
personal preference - many top sailors sail barefoot, others
still swear by Aigles. A wetsuit which goes below the knee
is a must for colder water, as it will keep the muscles and
especially the joint, ligaments, etc. warm and help prevent
injury. It also makes it easier to hike hard longer! These
can be made with hiking pads on them, which is the best way
to go if possible. A white long-sleeve rashguard really
helps keep the sun off, and a short and longsleeve spraytop
round out the wardrobe
nicely.
Fitness
Racing a Laser
when it is hiking conditions is very demanding physically,
with the quadriceps and abdominal muscles used upwind, and
the biceps and abdominals used downwind. The best way to get
in shape (and the most fun) is to sail in breeze. However,
only sailing will eventually present a problem: the quads
and biceps will become over-developed compared to the
hamstrings and triceps. And the quads themselves will be
imbalanced. This imbalance is very hard on the knees and
elbows, and can promote injury.
For someone serious
about Laser fitness, three times a week at the gym will make
a dramatic and important difference to their performance and
injury prevention. Seek the help of a certified trainer in
developing a program that addresses these areas:
- Improve hamstring and triceps
strength
- Balance quadriceps muscles (outer
quad usually needs some attention)
- Strengthen abdominals
- Strengthen lower back
- Flexibility - especially hamstrings,
lower back, and neck/shoulders
While on the road, some basic wall sits,
pushups, ab crunches, and lower back "superman" exercises
will help keep up what has been gained at the
gym
Other good training ideas include running,
cycling, roller-blading (especially in a tuck with long
strokes), and kicking in the pool (especially the butterfly
kick)
Gaining Weight
Gaining weight through
weight training is possible by age 16 or 17, but it takes
dedication. Consult a certified trainer about exercises and
proper diet for this.
Race Day
Fluids are very
important - it’s hard to get enough during a long day of
racing, especially when it’s cold and you don’t feel
thirsty. Sports drinks with electrolytes are good, and the
habit of drinking a water bottle for every hour on the water
is great. Make sure to have enough fuel too. Brining a
banana and an energy bar out on a long day helps prevent
hitting a wall during that last windy
race.
Legends
Currently two
sailors have won the Laser World Championship three times:
Glen Bourke of Australia and Robert Sheidt of Brazil. They
have many things in common, but the most notable are
incredible fitness, flawless boathandling, and good speed in
all conditions but especially downwind in the breeze. These
things come from one place - quality time on the
water.
Your sailors’ goals may not be to win the
Laser Worlds, but it’s important that they understand if
they want to make a jump in ability, it can only come from
working hard in the boat at the fundamentals.
