Marine Electronics Installation, Integration and Troubleshooting
Chartplotters, radar, sonar, autopilots, NMEA 2000 networks, engine data and digital instrumentation, dash and helm layouts, marine audio and lighting.
A lot of this work is diagnostic. Finding the cause is the job. Swapping parts until something works is not.
Most installs happen at your dock, slip, lift or trailer, without hauling the boat. Call 410-977-7127 or send the details through the form below.

Chartplotters, radar, sonar and autopilots selected, installed and networked over NMEA 2000 and Ethernet so the whole helm talks to itself.

3D scanned off your helm, drawn in CAD, cut on a CNC in acrylic or King Starboard, with engraved labels and backlighting. Five to eight weeks.

ABOUT BULL ON THE BAY MARINE SERVICES
Stephen Grochowski, owner and installer. Abingdon, Maryland.
I grew up on this water and I have been pulling electronics apart for about as long as I have been running boats. Bull on the Bay came out of doing both.
Custom dash panels are where that shows most. A panel starts with a 3D scan of your actual helm, goes through CAD, and gets cut on a CNC in acrylic or King Starboard. Laser-engraved labels and backlighting come through New Wire Marine. The old dash comes out, a panel built for your boat goes in, the electronics sit flush, and the wiring behind it gets done properly rather than patched.
I come to the boat. I work across Harford, Baltimore, Cecil and Kent counties on Maryland's Upper Chesapeake Bay. Tell me the boat, the equipment you are considering or the problem you are having, and send photos of the helm if it is a dash job. Call 410-977-7127.
