With the Volvo Penta Assisted Docking System, you’re in control with a simple joystick. Move forward, backward, sideways — or rotate in place — while the system automatically compensates for wind and current.
That means less stress, smoother maneuvers, and more confidence at the helm, even in challenging conditions.
Need a moment? Just let go. The boat holds its position and heading until you’re ready to continue. Available on DPI and IPS drives, it’s smart technology designed to make every docking experience safer and more predictable.
