NMEA regional director (1998) San Diego Boat Electric in Point Loma brings an EE degree and a 30,000-plus service-order track record in marine wiring to the Shelter Island basin. The veteran-owned operation specializes in failed DC-circuit diagnostics and shore-power overhauls that other technicians misdiagnose, handling deep-system troubleshooting that complements the generator and alternator focus at Marks Marine Electric along the Shelter Island corridor. Mobile crews service vessels dockside across San Diego Harbor and Mission Bay, eliminating haul-out costs for chartplotter integration, radar networking, and LED lighting retrofits. Navigation upgrades pair Simrad and Garmin multi-function displays with autopilot, AIS, and VHF networks, drawing from the same Shelter Island parts channel that supplies Shelter Island Marine Electronics. The operation's most demanding engagements involve full COI electrical certification for commercial passenger vessels, including load calculations, emergency-lighting circuits, and Coast Guard documentation packages.
