Fuzzy Wuzzy's sails are made by Bill Draheim @ GUS Sails - main & Genoa was new for last years NA and the spinnaker is new this year. The Genoa is a cross-cut polyester mylar, over the years I found the mylar film to be the weak link in the Genoa and in my opinion exotic (expensive) fibers is just a waste of money.
Our base tune is 37/37 and approx 4" slack in the backstay (adjuster is firmly secured at the top of the lower legs) headstay at max. For the first race Friday we went up to 40/40 and choose the #1, had to use the backstay in a few puffs. For the second race we went back to base 37/37 and never used the backstay, for the third race we backed off to approx 35/35.
Saturday we backed off the rig to 35/33 and eased the backstay to keep the 4" sag - we felt over tuned in that race.
Sunday we started with 32/30 - still too tight in the first race - backed off the rig to approx 27/22 for the last race.
In my opinion this was not a boat speed regatta -it was much more important to find breeze and try to avoid the very big holes scattered over the racing area.
We never figured out the current but I think it played a major roll in the light air races - perhaps some of the local boats can help us with that.
