Marine Electronics & Upgrades in Sandwich, MA

The short answer: anything that makes you safer, helps you find fish, or keeps you from getting lost on the water. The longer answer depends on how you use your boat.

At Atlantic Boat Repair we install and wire marine electronics for South Shore boaters from Plymouth to Falmouth. Chartplotters, fish finders, VHF radios, audio systems, navigation lights, and battery management are the most common upgrades we see. Ron has been doing this for 50 years, and the single biggest mistake he sees is customers buying good equipment and then having it installed poorly. A chartplotter that loses connection at 20 knots, a VHF antenna with bad coax, or a stereo that pops a fuse every time the bilge pump runs are all installation problems, not equipment problems.

We are NMEA-certified, which means we understand how these systems talk to each other. Most modern marine electronics run on an NMEA 2000 network, a backbone that lets your chartplotter, fish finder, engine data, autopilot, and depth sounder share information. Done right, one display shows everything. Done wrong, you have five standalone devices with no communication and wiring that looks like a bowl of spaghetti.

We work on all major brands: Garmin, Lowrance, Humminbird, Simrad, Standard Horizon, Fusion, Kenwood, and more. We will tell you which unit fits your console space and budget before you buy anything. Bring the boat in and we will give you an honest assessment of what your current setup can support and what is worth upgrading.
