Hi Pete,

what I learnt on the Dart 18 (which is one of the poorest boats I have ever sailed in chop) is to keep the bows down, e.g. go for a proper weight trim. That means not just go or sit more forward, it means constantly moving forward and backward to keep the boat level. On the wire it is easy, if you or you crew is sitting it can be more difficult depending on your deck layout (trapez shock cords, dagger boards, etc.). If possible let one hull fly, adjust the trim to do it. But most important is longitudinal weight trim.
On the Javelin 16 it is a bit more relaxed, to my surprise. I still have to keep the weight forward, but I don't need to run as much a long the hull as on the Dart 18.
On a Tiger or a Tornado, I felt like on Queen Mary, my weight didn't affect the boat... but maybe I have a different perception because I was used to sail the Dart.

Cheers,

Klaus
