In a Class by Itself

The 400Z is the ultimate center console that truly does it all. The completely revised design creates an abundance of space, additional storage and greater fuel capacity. Available with triple or quad outboards ranging from 900 – 2,000 hp combined with SeaVee’s industry-leading twin stepped hull means the 400Z boats superior speed, handling and fuel efficiency.

Step up to Performance

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, 400Z takes full advantage of this hull design. Capable of getting on plane with very little bow rise and planing at slow speeds the 400Z can comfortably cruise through the roughest seas and glide across tightly spaced waves. Turns are sharp, crisp and stable. And reverse chines redirect spray away and downwards for a dry ride. Experience the 400Z for yourself. Inquire about a sea trial today.
