On my A Class Cat (see avatar pic) I have put on a new and much fuller sail to get more off-wind and down-wind performance. As expected I have suffered upwind, to some detriment.
Naturally, it needs to be more flat upwind and needs more prebend in the rig, (10m of CF wing) but I don't want to lose shape by cranking it up too much and going back to where I was last season with my old sail.
I can really feel the drag upwind and against other boats it seems 'laggy'. Lots of downhaul/Cunningham helps but the sail gets stretched so much down the luff when you really crank it on.
My reason to post this?
Landyacht sails seem really flat and generate much higher apparent wind speeds, being an upwind machine that they are. I am hoping to get some advice from the LY speed freaks out there to get more speed out of my Cat, from anyone who can suggest something.
Any suggestions most welcome.
