We sail a C-22 and there are a few days where the wind is very light. We have a 150 genny, but we were thinking about a drifter sail for these conditions. I have never used one before, but for the right conditions they seem like they would be nice. How many have used these sails, and what weight cloth would be recommended? I was thinking about something in the 1.5 oz. range. ThanksDale
