You notice: slower, burning more fuel
Hull cleaning
We scrub the bottom from the waterline down to the keel, using the right brush for your bottom paint so the growth comes off and the paint stays on.

Hawaiʻi · in-water hull cleaning
We clean what’s under your boat.
Hulls, props, shafts and zincs, cleaned and checked in the water at your slip by a father-and-son dive crew. No haul-out and no yard bill.

What we do down there
Start with what you're noticing on the boat. Here's what usually causes it, and what we do about it. Keep scrolling to watch each job get done.
You notice: slower, burning more fuel
You notice: vibration, lost RPM
Props & running gear
We scrape and polish props, shafts, struts, rudders, trim tabs and intakes. A clean prop bites the water the way it was built to.
Prop polished
You notice: zincs look half gone
Zinc (anode) checks
We check your sacrificial anodes and swap them when they're worn, so they corrode instead of your prop and shaft.
Zinc replaced
You notice: you want to see it yourself
Underwater inspection
We look over the hull and running gear and send you the video. Useful before a trip, after hitting something, or when you're buying a boat.

What we leave behind: smooth antifouling, nothing slowing you down.
Stage 1 · weeks
Slime
A thin brown-green film. It shows up within weeks and starts adding drag before you can see much.
A quick wipe-down handles it.
Stage 2 · a month or two
Weed & grass
Soft green growth, thickest along the waterline where the light hits. This is when the boat starts feeling lazy.
A full scrub of the hull.
Stage 3 · left too long
Barnacles
Hard shells that grip the hull and props. On a propeller they cost you speed and cause vibration.
Scraping by hand, then a polish.
