The Best of Everything

Put simply, the SeaVee 340z is a dream machine! Available with twin or triple outboards ranging from 600 – 1,350 hp the 340z screams performance. Thanks to SeaVee’s award winning twin stepped hull the 340z boasts superior speed, handling, ride quality and fuel efficiency. Add to that plenty of deck space for the whole crew and almost limitless storage capacity. It’s obvious why this is the ideal boat for long weekends on the water.

Individual results will vary with engine package, load and conditions.

Step up 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.

The 340z makes the most of this hull design. Capable of planing at very slow speeds, the 340z handles rough seas with ease. Turns are sharp, crisp and stable. A newly designed larger bow with reverse chines redirect spray downwards for a dry ride. Experience the 340z for yourself. Inquire about a sea trial today.

The Power of Choice

When you’re building a SeaVee, the brand of motors you choose to hang is up to you. For the 340z, two motors are adequate, yielding a top speed somewhere between 50 – 55 mph depending on boat layout and engine choice. For those seeking a higher level of performance, triple 450 hp motors are an option. Expect a top speed in excess of 70 mph with only a modest increase in fuel costs compared to the equivalent twin setup. That’s because three engines run at lower RPM’s and therefore don’t use significantly more fuel than twins at comparable speeds.

Fishing Machine

Nothing fishes just like the 340z. For starters, you’ll be the first to arrive at the spot. Thanks to an abundance of in-deck storage lockers, fish boxes and rod lockers, as well as more space inside of the console, you can bring all the gear and ice you need. The 340z can carry up to 42 fishing rods neatly tucked away under the deck, on the sides of the console, in the t-top and on the back of the leaning post.

A 65 gallon bait well is integrated into the transom with an optional adjacent 30 gallon well available. A third well can be added in the front cockpit sole for maximum capacity. An optional fiberglass cooler slides out from below the tackle station leaning post on stainless tracks to create a rear-facing seat to make keeping an eye on the spread more comfortable.

Additional fishing features include a variety of towers and upper stations choices to help the captain spot fish at a distance. A Coffin box for the front cockpit as well as electric reel outlets and a variety of outrigger configurations complete the package.



Towers allow the captain to spot fish at a distance. SeaVee offers a wide variety of choices.

A Modern Day Console

The 340z features a dedicated console designed to maximize deck space, while providing plenty of room on the inside.
