Welcome to Down Under

Down Under Dive Service is a family owned business, serving the boating community since 1992.

We adhere to The Best Management Practices guidelines, and we are licensed and insured.
Our focus is to care for your boat underneath, so you can focus on making memories on board!

We offer almost any underwater service a boat owner needs. Services such as bottom cleaning, complete hull maintenance,  & inspection services (either for insurance documentation or simply for piece of mind) and many other services.

By keeping your bottom clean you’ll get huge fuel savings and greater craft performance. Consistent monthly cleanings will remove the algae & barnacles that accumulate on the antifouling paint. The underwater cleaning activates the paint to better perform against marine growth. Monthly underwater cleanings will extend the life of your bottom paint. Along with monthly cleaning we will inspect & replace worn or missing zincs as needed.

We service all marinas in the general San Pedro area.

This includes Cabrillo Way Marina, CYM- Cabrillo, Holiday Harbor, Cabrillo Beach Yacht Club, Ports of Call, and San Pedro Marina.
We service individual accounts, fleet accounts, brokers accounts, and commercial accounts.

Some of Our

Services

We service individual, fleet, broker, and commercial accounts

Hull Cleaning

We provide underwater hull cleaning services that extend from the waterline to the keel. A thorough inspection of all thru hulls and instruments will be performed.

Zinc Replacement

Sacrificial anodes are metals that are quicker to give up pieces of themselves in order to protect underwater metals. They are most commonly made from zinc, as it is the best alloy for protecting your boat in water.

Propeller Removal and Repair

Feeling a vibration? Hit something recently? We are able to pull and install any prop with your boat in the water. No more need for haul outs.
