I’ve run enough boats of various sizes to know less WSA does not always make a boat faster. In many cases, it’s just the opposite. Beam, overall length, shaft angle and deadrise contribute to this as well. Many times, when you have two boats with the same power, same weight and only a couple of feet of difference in length, the longer boat is faster. I’m oversimplifying, and I’m sure some engineer somewhere is cringing, but I’ll take him out in real-life conditions with gear on board and prove it almost every time.
