Maybe Sail is cut wrong for boat
Tim,From your photo, it looks like the block for your sheet is as far aft as possible for your boat--which still may not be far aft enough for the cut of this particular sail. I.e., the clew is too high and the foot is too long. I think you could still have a 150% genoa but with a shorter foot and lower clew which would theoretically allow you to get the sail much tighter without having your jib car hanging off the stern rail. The trade-off here is that the leech of the sail will be longer, bringing it closer to your deck and cutting down on visibility from the helm forward (i.e., more of a "deck sweeper").I had the same problem on my O'Day 22 with a supposedly stock 155% genoa--it was cut with the clew about 2 to 3 feet off the deck and a foot length that would have forced me to have a jib car about 2 to 3 feet behind the stern of my boat in order to sheet that sail properly. (Maybe I could have given it to you since your boat is 3 feet longer???) I then measured myself for a better fit, effectively bringing the clew down about 2 feet and forward about two feet, lengthening the leech and bring the sail's foot closer to the deck. I can't see around the sail very easily (that's what crew are for) but I can now keep my jib car much more forward and still get a decent sheeting angle on the sail, allowing me to point where I could not with the other sail. Talk to your sailmaker about this and see what he says.Richs/v TIME BANDITO'Day 22
