Poseidon Boat Services offers hull cleaning, anodes replacement, underwater diver survey, propeller polishing and replacement, and underwater lost items retrieval in the San Francisco Bay Area. Our goal is to maximize your boating pleasure and performance, save fuel, and to help protect your investment and the environment.

Serving the marinas in Alameda (24 hours), Berkeley, Emeryville, Oakland, Richmond, San Francisco, Sausalito, and Treasure Island.

Poseidon is San Francisco Bay Area’s premier underwater hull cleaning service specializing in boats with severe fouling.

Hull cleaning is one of the most important preventative maintenance services you can do to extend the life of your boat. A clean bottom will provide you with better fuel efficiency on the water, faster speeds, and will reduce pollution.

We recommend hull cleaning every 2 months in summer and 3 months in winter.
