A clean, new marine electrical panel

A Captain's Approach to Electrical

A boat’s electrical system is its nervous system. As a 15-year captain, we've troubleshot critical failures in the worst possible conditions. We know that reliability isn't a luxury—it's essential.

We are 'standards-obsessed,' adhering to both ABYC (electrical) and NMEA (electronics) standards for every job. We don't just connect wires; we build safe, logical, and fully-integrated systems that work when you need them most.
