This hull definitely delivers a unique ride. When a Flat's Cat passes over the water, air is injected or rammed into the large bow entrance raising the boat up out of the water allowing the boat to ride on top of the waves and gently walk from side to side on the Cat hulls, thus eliminating the pounding affect created by most mono hulls. The seemingly flat hulls push water straight out away from the boat, far enough that spray cannot be drafted up the almost vertical sides. I really like the Flat's Cat because it's so unique. For one thing it's very easy to pole.
Water flows through the two hulls helping to eliminate drag.
With the absence of a keel, there's no veering or cutting from side to side. And when you're drifting water going between the hulls positions the boat at a 45 degree angle to the wind. That allows you to drift in a desired direction. The transom is another interesting thing about the Flats Cat. The outboard is elevated high on the raised transoms and even higher with power lifts.
