Pros and Cons of a Stepped Hull

As you look for your next boat, you have probably noticed the growing popularity of stepped hull boats. Originally these were only on race or “Go Fast” boats. But as time has gone by, they have been showing up more and more in the larger market space. So, is a stepped hull right for you? To answer this question, you need to know the pros and cons and how they relate to your boating needs.

But before we get to the pros and cons, it is good to know how a stepped hull works. The basic premise is that the steps introduce air under the hull which reduces wetted surface. Each step creates a low pressure area just aft of the step which creates suction, drawing air in and under the hull. In the newest stepped hull design by Michael Peters called SVVT (Stepped Vee Ventilated Tunnel), the air is directed into a tunnel behind the steps to increase the fuel efficiency, give a better ride quality and better handling.
