All boats with electronic engine controls can be equipped with the Dockmate® system, regardless of the length or type of the boat. Our Twist transmitter, preferably worn with the included neck strap, is completely waterproof and floats. It is only the size of an iPhone and has a very simple, clear layout. In our most simple configuration, the Twist transmitter sends a coded digital signal to the receiver which operates the engine(s) and horn. The system can be extended modularly to also control the bow thruster, stern thruster and windlass. Operation is easy, accurate, safe and reliable, and can be done from any location aboard the boat. If the Twist transmitter somehow slips out of your hands, then all systems immediately drop to neutral. There is also an automatic shut off after 30 minutes of non-use.
