That statement extends to power and propulsion as well. Twin 352-bhp Volvo Penta IPS 500 tractor drives bestow the 400 Sport Yacht with range, speed, sporty handling, and uncanny docking agility. Push the levers. The 400 Sport surges forward, climbs its bow wave like a mountain goat with a puma in pursuit, then slingshots to a 41-mph top speed. When collecting performance data, I don't use the tabs, but it's silly for you not to use them to fine-tune for trim, load, and conditions. Similarly, you can dock an IPS-powered boat like the 400 Sport Yacht without using the joystick. But why would you? The technology is aboard, is proven, and makes life easier. The 400 Sport Yacht spins and backs into its slip with grace.
