RE: fast step hull
The addition of the step is beneficial to a hulls performance. At first you have 2 surfaces touching the water when on a mid to full plane and this eliminates the porpoise effect that comes along with having only one surface in the water trying to balance out the weight of the boat. Second the step allows for a controlled hydroplane effect and this happens when air is allowed to flow under the hull and leaves as compressed air under the transom hence actually making less drag and with this in mind the actual boat weight vs. the surface weight friction is reduced. If you were to take a flat bottom hull and a step hull “same length” and rig them out with the same motors and with the hp the same and have the same propellers and the same weight riggings the step hull will travel further on fuel, faster at top end, and will ride flatter. On the other hand the operator must adjust to the way that a step hull is operated in driving as compared to a flat bottom. A flat bottom will dig in a turn as where a step hull will slide. I have seen where full size boats must start turning before the actual turn and power out of the slide. But the last statement was from my own personal experience.</p>
