mainsail roach
Bob I have a 216 and I wouldnt consider a backstay. The 216 is a fractional rigged boat, that means a small headsail and a large main. Part of the power the main generates is from a large roach, this is the part of the leech above midpoint in the sail. If you install a backstay it will interfear with the roach when tacking resulting in premature wear and would be difficult to swing the main over in light air. As far as a traveler is concerned I race my boat and havent felt the need for it yet. I may install One in the future if the competition heats up. For cruising I wouldnt want one because it breaks up the cockpit, eliminating one of the boats great features, a huge unobstructed cockpit. Hope this gives you a better understanding of the 216. Have a blast. Ray T
