Yeah, I got a 155 for mine. Doyle Sails. It sheets at the forward end of the track. But that's because the clew is lower. It depends on how the sail was cut. A higher clew would sheet further back. It's something to discuss with the sailmaker. Some owners have problems with the sheeting lead interfering with the cleat. I tend to get overrides on the winch. I'll probably install blocks on the winches before next season.
