FastBottoms Hull Diving As the San Francisco Bay Area's premier hull cleaning company, we have been providing prompt, professional underwater services to boaters since 1994.

FastBottoms Hull Diving has been providing prompt, professional underwater services to San Francisco East Bay boaters since 1994. Hull cleaning, zinc replacement and propeller R&R. We are a PYI-recommended Max Prop installation specialist and dealer. As members of the California Professional Divers Association, we have been trained and certified in the use of in-water hull cleaning Best Management Practices, making our divers amongst the best educated, most environmentally proactive hull cleaners in the state. Don't be fooled by jack-of-all-trade, fly-by-night boat maintenance workers or recreational scuba divers looking to make a quick buck. There is a difference. We are professionals and we have the tools, parts, knowledge and experience to properly maintain your boat's bottom and maximize the life of your expensive anti fouling paint.

While we may not always have good news for you, the news we give you will always be honest and accurate. And that's worth a lot.

"Hi Matt.
Just wanted to say thank you. It was on my last service that you changed the condition of my bottom paint from good/fair to fair/poor. That timely and accurate assessment saved me several hundreds of dollars in prep time at KKMI/Safe Harbor. At $149 an hour, had I waited a few more months to haul, that would have likely added $500 to the bottom job.
I appreciate you. Thank you."

Is your hull extremely foul? Got a boat that hasn't been cleaned in years? 100% covered in shelled animal fouling? Let us take care of it for you. In situations like this, we use the Caviblaster- an advanced underwater cleaning system made by CaviDyne LLC. It uses ultra-cavitation technology—forming and collapsing microscopic vacuum bubbles—to remove marine growth, algae, and barnacles from boat hulls, docks, and other underwater structures safely and quickly without damaging paint or protective coatings. This is not a pressure washer and is completely non-destructive to paint or hull materials.

We picked up a new sailing school client last week. This is what the owner had to say this morning after asking us to clean four more of their boats:

"Extra work follows excellence. Your team did a really good job. The boats moved and sailed better than after our regular divers."
