The Hull Truth: SeaVee Z
SeaVee's stepped-hull boats provide sure handling in a variety of sea conditions. For a complete performance report of the 390-Z, look for our test during 2014.
Case Study: Larson's Duo-Delta Conic Hull
Larson licenses Harry Schoell's patent for this design, which it uses in its sport cruiser line. The running surface is stepped to create two sections of hull on the water at plane, one forward and one aft of the notch. Together they're much smaller than the single contact area of a typical V-bottom. Less wetted surface means faster top speed.

This design also reaches that speed more quickly. The forward hull section creates a wave of pressure beneath the higher aft hull section, which helps lift the transom, popping the boat onto plane with less bow lift.
"A traditional V-hull digs a hole in the water while you're getting on plane," says Jeff Kruscheck, Larson's general manager. "With the stepped hull, what you have is almost a natural trim tab." We've tested it, and the hull lives up to the hype.
