Boat Description

The primary design goal for the 40z was to create a 40 foot powerboat that would handle like a 30-footer at idle speeds in tricky docking situations. The Volvo-Penta IPS or Cummins Mercruiser AXIUS joystick control technology makes this goal a reality. The IPS system works with twin pod drives under the hull and the Cummins with twin sterndrives. When conventional twin-engine controls are in neutral, a single joystick takes over with fingertip control. There are no thrusters. Through a unique computer program, each drive unit is independently operated in terms of direction, rpm and forward-reverse gear. This system works far more intuitively than conventional twin shaft drives or joystick/thruster operated jet drives.

Unique Features
-Side-opening doors (P&S) overcome a common problem, getting aboard or getting off when handling docklines.

- Single-level seating for as many as 15 at cocktail time or for a family picnic

- Roll-up side/aft curtains and fully-opening windshields to regulate airflow in the pilothouse to suit conditions.

- Large (60x78) island berth and separate shower in owner stateroom.

- Two convertible guest cabins, one with dinette option.

- 40z can be trucked overland without penalty. Width doesn’t exceed 12 feet and height on a trailer is less than 13.5 feet.
