Blue Sea Systems


Innovative electrical systems, built to last.

Over 1,000 electrical products designed to work together as a fully integrated system.

Panels

At the heart of a boat's electrical system is the power distribution panel. Blue Sea Systems manufactures panels for small runabouts to large offshore cruising yachts, with four panel styles to choose from.

Automatic Charging Relays

In a boat or vehicle with two battery banks, it is useful to be able to charge both banks while underway. Charge management devices allow two battery banks to be charged from a single source, such as an alternator, but keep batteries isolated when not charging.

Busbars and Insulators

The nuts and bolts of any electrical system are the connectors which keep the current flowing. Blue Sea Systems connectors reduce heat and improve efficiency and reliability in a boat's electrical system.
