Hull form 
Every SeaVee Z features a twin stepped, cross-ventilated hull with patented SpeedRail® technology. Multiple lifting bodies with unique geometry ensure a fixed trim angle throughout a wide range of speeds. That’s a fancy way of saying you always have a clear view of the horizon, maximum fuel efficiency, more speed and safe predicable handling when making hard turns.
With its massive length, 390z takes full advantage of this hull design. Capable of planing at very slow speeds the 390z can comfortably cruise through the roughest seas and glide across tightly spaced waves at high speed. Turns are sharp, crisp and stable. And reverse chines redirect spray away and downwards for a dry ride.
