About Blue Sea Systems

Blue Sea Systems builds marine-grade AC and DC electrical products designed to make boating safer and more reliable. Based in Bellingham, Washington, the brand is known for practical engineering that helps boaters and builders create clean, serviceable electrical systems that hold up in harsh conditions.

Their catalog covers the core building blocks of onboard power, including battery switches, automatic charging relays, fuse blocks, bus bars, circuit breakers, meters, and power distribution panels. Whether you are rigging a small skiff, upgrading a cruising sailboat, or wiring a specialty vehicle, Blue Sea components are made to work together as a complete system.

At Lotz Outdoors we stock Blue Sea Systems because dependable electrical is not optional on the water. If you are chasing a tidy install, easy troubleshooting, and confidence when the weather turns, this is the hardware that helps you get there.
