Measured from top of mast to top middle of transom. If measured with the sail up
ease the kicker and ease the sprit so that mast bend is not affecting the
Max rake 2770mm Minimum rake 2850mm.
The amount of rake you choose to sail with will be determined by your weight and
sail power. The heavier sailors will want to stay upright for more power and the
lighter sailors will need to rake to de-power. Remember that you are stuck with your
rake settings for an entire race so you should avoid the extremes. It is generally best
to stay in the 2800 to 2820 range.
We recommend 40mm +/-5mm from the clew to the inside edge of the outer boom
fitting in most conditions. Use the lower leech tell tale to check whether you have too
much eased. If it is stalling before the top telltale then try pulling a little on. Too much
on and you will reduce your pointing ability.
Lightweight helms may need to pull more outhaul on in strong breeze. This will help
reduce the power and the weather helm.
If it is possible try easing 2cm of outhaul downwind for even more power! 9only if you
are confident you can re set it up –wind
Luff tension is difficult to measure but is vital. In light winds set the luff tension so that
there are hints of creases coming from the eyelets. In more breeze you will need to
increase the tension but never so that there is a vertical crease behind the mast!
Too much luff tension will pull the flow forwards and reduce pointing. If you are not
pointing ease the tension until wrinkles appear.
In up to 10 knots of breeze set the sprit so that on port tack you get a small 30cm
crease in the throat-clew direction on the sail where the sprit touches the sail.
In more than 10 knots until over powered increase the tension so that you remove
the crease but never pull enough to get the crease running along the line of the sprit.
Once over-powered ease about 1cm of sprit, which will allow a crease from throat to
clew but opens the leech reduces weather helm and is faster than fighting the boat
The kicking strap should be just slack up-wind. Mainsheet over-rides the kicker.
Down-wind you should have enough tension so that the top batten is parallel to the
boom. Too much and the leech hooks and will not flick open over waves, too little
and you have too much twist and the breeze exhausts out of the upper leech giving
less drive and making the boat unstable.
Set the sail 5mm from the mast in 5-10 knots of breeze. As the wind increases 10-15
knots reduce to 3mm and 1mm when overpowered.
