Bill and Jake...Very interesting discussion. First I should say that I am an Architect which means I know enough engineering to be dangerous. My question is this, Increasing the righting moment only increases the max wind speed that can be accepted before depowering is required. But there will be a range of wind speed where a narrower boat with wings will fly a hull and the wider boat will not. In this range isn't the narrower boat faster all other things being equal. Sometimes a lower righting moment is desireable...Dan
