Sail Plan?
There are two major items that can affect heeeling: Sail plan and sail shape. One of the advantages to the tall rig is that you can keep sailing in light air while other boats with a shorter rig have to power up. As a couple previous posters mentioned if the sail plan is too large for the conditions this will cause too much heel. Besides heeling, the other thing that happens when carrying too much sail area for the conditions the sails are in the process of getting blown out.Sail shape: If the sails have too much draft, such as when they're blown out, the heeling will increase if one is sailing by the wind angle on the luff. The alternative is to sail by the leach tell tails in which case, with blown out sails, the luff is being luffed and the boat isn't performing.Sail Plan: The solution to the tenderness problem, if the sails are not blown out, is to put a reef/another reef in the main and use a smaller jib area. Reducing the jib area means either changing to a smaller jib or, if the jib is a reefing jib, furling it in accordingly. With a stronger breeze and smaller sail area the boat will not heel as much, the weather helm will be reduced, it will be easier to control the boat, and everybody will have more fun.Sail trim: Is the main and jib sheeted in too tight going to weather? This could be a contributing factor too.With blown out sails there is not much that can be done for sailing performance. The boat will heel more and sail like a slug so the soulution is to either get them recut (stop-gap measure) or buy new sails. If you've been sailing on the San Francisco bay my guess is you might be in the market for new sails. We recently bought new sails and opted for a sailcloth weight that was the next weight heavier than the OEM sails so they'd last longer.Try some combinations this weekend and see what works better.
