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 new Volvo-Penta IPS or Yanmar joystick control technology makes this goal a reality. The IPS system works with twin pod drives under the hull and the Yanmar 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 new system works far more intuitively than conventional twin shaft drives or joystick/thruster operated jet drives. Dynamic Positioning System (DPS) is standard with the Volvo-Penta IPS. This hovering or 'skyhook' feature is not yet available with the Yanmar sterndrive option.
