Historically, marine electrical systems have been relatively simple, but with the advent of more modern electrical components, systems are much more complex. Onboard, you'll want enough power for lights, refrigeration, generators, propulsion, and communications equipment such as your radio and VHF. Navigation equipment, such as computerized charts, GPS, and radar, are becoming more common additions. Some vessels carry more specialized technical equipment, such as research instruments or advanced monitoring devices.

All systems need a source of power and a means to distribute the power throughout the vessel. At the dock, your boat's electrical system can run off of shore power. Underway or at anchor, you'll need batteries and generators. Safe and reliable operation of the electrical system depends on using appropriately sized wires, cables, breakers, and switches.

Proper grounding will keep you safe and will help to prevent galvanic corrosion due to stray currents. The Co-op can assess your needs and design and install the right system for your boat.
