The boat analogy may not hold much water. <g> The size of wake from a boat is from the HULL and it's SPEED. When going faster, you unwet the hull by riding higher out of the water, giving the narrower/smaller wake. If you can go fast enough, only the prop is essentially in the water, causing little impact to the surrounding environment, i.e., little wake. Following this analogy, you have a wider wake because..... YOU ARE GOING SLOWER. Your data appears to contradict this. Bob Urban
