HDSAILS Optimist SailTuning Guide
By jamie Harris (National Squad 2013-2014)
Do not choose/use a too powerful sail as this will make you tired quickly in heavier winds. This is because you will have to hike harder for longer HD1’s are great for conditions where
there is very little chop, you are a light sailor or you are looking to optimise your pointing.
One of the main and most important controls on the optimist sail is the Sprit
In the optimist, try to set your sail to lulls, the sail will develop small ‘speed’ creases in the top throat of the sail pointing down to the end of the boom whena gust comes, The sprit has a
huge effect on the leech , this means you do not want a crease going from the tack to the peak
following the sprit. This hooks the leach and will stall the sail in light conditions. This means
you don’t want much sprit in the light conditions. If possible you can change your sprit when changing leg, putting it on to go up wind and taking it off down wind.
However this is not crucial, and you can easily get away with not doing it. But you must make sure the sprit is not too tight for downwind. To depower in strong winds, you can drop off the sprit so
there is a small crease coming from the top of the mast pointing down to the end of the boom
. This depowers the top of the sail so you can cope with the conditions (even though it doesn’t look very good). However only do this as a last resort in survival conditions.
The Kicker controls the leech and the bottom half of the sail from the top of the mast pointing down to the end of the boom. Downwind the kickercontrols the leech, gives the sail
power and stops the boat from rolling. Upwind the kicker is often slack with the mainsheet
controlling the leech. This is until heavy winds where you need to keep the kicker tight so that when you ease the mainsheet in the gusts the kicker keeps the boom flat. Check your kicker downwind before the start, it is easy to forget your downwind speed whilst focusing on
upwind. Remember to check it, it is very important!
The out haul controls the foot, depth and leech of the sail. The outhaul can be adjusted on the water, so make sure it is set up correctly. When the out haul is loose scallops will appear
between the sail ties, these should never go above the first seam of the sail at maximum
In flat waters you need to tighten the out haul so you can point higher, as you do not need the power. When you need the power to sail over the chop you can power up by loosening the outhaul to gain drive over the waves. Once you need to depower in strong winds, you need to
keep the outhaul tight to depower the foot of the sail.
The mast rake controls the boat balance ’ The rake should be around 111-112 inches. Check the rake by putting a tape measure from the top of the mast to the radius of the transom top.
Change it on the water to adjust it to the wind strength, making sure the boom is level with the
water line when sailing upwind close hauled. To do this sail upwind on starboard to check if your
rake is set correctly, make sure that the boat is flat, all the controls are set correctly and the tell tales are flying horizontally. When everything is good let go of the rudder to see what happens;
if the boat soon heads up, you must move the mast forward and if the boat wants bear away you
must decrease the mast rake. Do this until the boats heads up gently, this should be about the right balance. Every time you sail, the conditions are different so one mast rake won’t work
in all conditions.
