Sea state will play a part in the "attitude" of the hulls, but I've found that she seems to go well in chop when the weight is right at the side stay (my feet were on either side). I am by no means an expert, but tht is how I felt the boat best performed in lumpy conditions. Flat water and I may tend to get forward a little more....
Either way, if you are going to continue sailing uni - you need a new tiller extension. You need to be able to move forward in light air or be able to adjust forward controls. Check out the Ariba all carbon version tiller extension.
Any other opinions on weight placement?
