110, 135 and 155
I have a 110 a 135 and a 155% Genoa for my 1986 28.5 -none are hank on or roller furlers as I use a 'HeadFoil' system. Like Cliff, the 110 has had the least use, but the 135 and 155 are used about equally. We sail, cruise and race(a little) but in light air and below 12 knots we use the 155. When its above 15 knots, and up to about 22 with the 135, she runs like a freight train, and we start flattening the main to control weather helm. Actually , that's one of the benefits of having the sail selection available. We choose the best headsail and trim the main to perfectly ballance the boat. So what is the wind speed you expect to sail in most often? If you are not interested in racing or in eventually buying another sail, split the difference and have a good sailmaker build a 145% using mylar & dacron triradial laminate technology. My original all mylar 155% lasted for 16 years.
