Electrician Marine US East Coast Connecticut Delaware. This directory lists boat electricians, marine electronics technicians and boatyards in Connecticut, New York, New Jersey and Delaware. It follows the coast from eastern Long Island Sound through western Long Island Sound and Long Island, then south along the New Jersey coast to Delaware Bay. Each entry gives the provider’s base, the work it lists and a contact number or service link.
Marine electrical services in this directory include AC and DC fault-finding, rewiring, battery and charging systems, and shore-power work. Marine electronics services include the installation, integration and repair of chartplotters, radar, autopilots, AIS, VHF radios and onboard networks. Equipment dealers and commercial marine service offices are identified separately where their published scope differs from that of a boat electrician.
