Cushioning effect, was Catamarans versus MonohullsI would like to hear what Roger Hill has to say on the subject. He has designed a lot of this type of boats.

The environment that is created by having two parallel floats(hulls) causes for air to be trapped between these two apparatuses providing additional lift. This provides an invisible cushion as the vessel passes over wakes and waves. Bob Deering wrote: I've heard this claim repeated many times, but I'm not convinced that it's significant.
