da versus high tech
Hi J. The ultimate setup is 2 mains. No. I''m not a sailmaker but a former yacht broker quite familiar with the 727. By current standards the boat is underpowered and composite mains tend to be too flat in light air. I owned a Kirby 25 and decided on a light Dacron main in the light stuff-I maxed the roach and full batten up top. It allowed me to shift gears quickly and was very fast in all but blade conditions. Can''t beat carbon in the heavy stuff though, the dialed in shape (as long as its fast out of the bag)is more stable. I''ve learned that winning isn''t cheap. If budgets a concern evaluate your average windspeed over the race season and canvas to the average.
Good luck on the course.
