We design and install NMEA 2000 networks so your chartplotters, sensors, and electronics communicate properly for a seamless experience on the water.
We also handle the upgrades that make a boat feel brand new, including autopilot installation and commissioning, LED lighting (deck, courtesy, and underwater), and marine audio systems with modern speakers, amps, and zone control. As an NMEA-certified installer and certified by major brands like Garmin, Raymarine, and Simrad.
