Underwater hull service for the harbors of San Pedro, Long Beach & Los Alamitos

Down Under Dive Services works the waterfront where you keep your boat — the slips of San Pedro, the basins of Long Beach, and the docks of Los Alamitos. We are in the water year-round, keeping hulls clean, zincs fresh, and running gear sound for the owners and captains who berth here.

This is diver-led work. The person who inspects your hull is the person in the water, and that hands-on approach is how small problems get caught before they turn into haul-out problems.

We know these harbors

Water conditions, growth rates, and current vary from the outer harbor to the back basins. Working these specific waters every week means we clean on a rhythm that actually fits where your boat sits — not a generic schedule.

Caught early, fixed cheap

A diver who sees your boat regularly notices the things you cannot from the dock: a zinc nearly gone, a thru-hull starting to foul, the first signs of growth on the prop. Catching those early is the whole point of a standing service.
