This application is highly integrated into our Helmsman Navigation System, which is a boat controller designed to do four major things: Navigation: Accurate waypoint navigation thanks to an excellent GPS receiver using online maps. Cruise Control: For efficient sailing or trolling with a set speed, even in bad conditions. Record Route: You can record your routes so you can re-use them on your next trip. Anchor: With a push of button your boat will stay where it is, convenient and reliable.
