What we do
Everything below the waterline, handled.
Since 1979, Barney Culls has kept boat bottoms clean and back-bay water moving in Huntington Harbour and the surrounding marinas. Hull cleaning, zincs, props, thru-hulls, and bottom paint for boat owners. Pressure washing and float cleaning for docks and marinas. Intake and flow-area cleaning for harbors and back bays. One diver, no haul-out, no surprises.
For boat owners
In-water service, no haul-out.
Every job below is done with the boat in the water, on a schedule that fits how you use it.

Monthly hull cleaning
Divers scrub the barnacles, grass, and slime off your bottom, running gear, and waterline on a set schedule. Growth never gets ahead of you, and your paint lasts longer for it.
MonthlyZinc & anode replacement
Anodes get checked on every visit and swapped before they wear through. Left too long, a spent zinc lets electrolysis eat at your running gear instead.
AskPropeller pulling & running-gear service
Props pulled, cleaned, and reseated in the water, along with shafts, struts, and running gear. No haul-out, no yard bill, no boat out of the water for days.
AskUnderwater thru-hull replacement & installation
Thru-hulls replaced or installed below the waterline by the diver, on your regular visit, without dry-docking the boat.
AskBottom painting
Fresh bottom paint applied to keep growth off and slow the next round of barnacles. Done right, it makes every cleaning after it faster and cheaper.
AskWashdowns
Topside washdowns to knock salt, spray, and grime off your boat between cleanings.
AskUnderwater inspection reports & photos
Ask for a report and we hand back notes on the condition of your hull, zincs, running gear, and thru-hulls, no diving of your own required. Underwater pictures on request.
AskSalvage
Give us a call if you drop something in the harbor or your boat sinks, and we will retrieve it.
AskElectronic Retro-Fit
Bring an older boat’s electronics current: navigation, electrical, and instrument upgrades. Tell us what you’re running now and what you want out of it, and we’ll quote the retro-fit.

For docks & marinas
Docks stay clean, floats stay light.
Whether it’s the walking surface or the underwater structure, we keep docks and floats free of the buildup and growth that bog them down.
Topside dock pressure washing
Decking, gangways, and slip surfaces washed clean of grime, algae, and stains. Soft-washed on wood, full pressure on composite and concrete, so the surface comes clean without getting torn up.
AskDock float cleaning
Mussels, barnacles, and marine growth pulled off your dock’s floats and pilings. Left alone, that growth adds weight and drag to your float. Cleared on a schedule, it never gets the chance.
AskUnderwater dock cleaning
The diver works the parts of your dock you can’t see, the understructure below the waterline, the same way we clean a hull. Growth down there is the kind that never gets noticed until the float sits low.
Ask
For harbors & back bays
Intake & flow-area cleaning.
HOAs, marina and harbor management, and water districts call us to keep intake and flow areas clear. We pull the algae, aquatic weed, and sediment that build up and choke the circulation a back bay depends on.
Left alone, that buildup slows water movement through the whole channel. Cleared on a schedule, the water keeps moving the way it’s supposed to.
