Re: Main and Jib Trailing Edge Flapping
At 25 knots, you should most certainly be reefed. Reefed or not, making certain the leech lines are tightened will help, but also be sure to tighten the outhaul to help flatten the sail (and the belly) and tighten the cunningham to move the draft forward. The combination of the three will give you the best possible sail shape. If you are reefed, make certain you don't have any scalloping in the luff by having the reefed portion secured tightly to the boom. It's sometimes difficult to get a really efficient sail shape when you're reefed.
A reefed headsail is even more difficult to attain a good shape.
Good points, I will give it a try.
