Marine Services in Stuart, FL
Our Treasure Coast dive team provides a full range of underwater and waterfront maintenance services for yachts, sportfishing boats, sailing vessels, and commercial craft throughout Stuart and the surrounding areas:
Hull Cleaning: Regular underwater hull cleaning removes barnacles, slime, and biofouling before marine growth increases drag and fuel costs. Essential in the Treasure Coast’s warm, year-round waters where growth cycles are aggressive and unrelenting.
Cavitation Cleaning: Non-abrasive ultrasonic cleaning for propellers, running gear and other unpainted surfaces, and for pilings, seawalls, floating docks and lifts. Removes growth without damaging your antifouling coating or polluting the surrounding water.
Zinc Anode Replacement: We inspect and replace zinc anodes on every applicable service, protecting your vessel from galvanic corrosion in Stuart’s marina environments and the Indian River Lagoon’s brackish conditions.
Dock Cleaning: Professional cleaning for docks, finger piers, and dock hardware to maintain appearance, prevent deterioration, and protect your waterfront investment.
Piling Cleaning: Marine growth on pilings accelerates wood rot and structural damage. We keep your pilings clean and extend their lifespan with regular maintenance.
Seawall Cleaning: Algae, barnacles, and biofouling buildup on seawalls can conceal cracks and accelerate erosion. Our seawall cleaning service keeps your structure visible and protected.
Lift Cleaning: Boat lift frames and bunks accumulate growth and corrosion quickly in the Treasure Coast’s saltwater environment. We clean and inspect lifts throughout Stuart’s waterfront communities.

Why Treasure Coast Yacht Owners Choose Barnacle King
The Treasure Coast‘s unique mix of saltwater, brackish estuaries, and year-round warm temperatures creates some of the most varied and demanding biofouling conditions in South Florida. The Indian River Lagoon and St. Lucie River support exceptional biodiversity, which also means barnacles, slime, and algae attach aggressively to vessel hulls and waterfront infrastructure alike.
Barnacle King was built for exactly this environment. Our Stuart dive team cleans bottom-painted hulls by hand, because light brushing on a regular schedule lifts growth without taking off the paint you paid for. Cavitation is used where it belongs: running gear and other unpainted metal, hulls running bare gel coat, and pilings, seawalls, docks and lifts.
We also support vessels preparing to depart for the Bahamas, head south toward Miami and the Florida Keys, or compete in events like the Stuart Sailfish Club tournaments and offshore fishing tournaments along the Treasure Coast. Whether you keep your vessel at Harborage Yacht Club, Pirate’s Cove Resort and Marina, or a private dock in Sewall’s Point, our team tailors every service to the demands of the Treasure Coast’s boating environment.
Every service includes:
✓ Real-time GPS diver tracking
✓ Post-clean photos and a written dive report
✓ On-time guarantee: if we don’t confirm within 30 minutes, your first clean is free

Brackish water up the St. Lucie lets many Stuart boats stretch to a five or eight week interval, which we set on a recurring Hull Protection Plan. Waterfront communities here usually combine hulls, docks, pilings, seawalls and ladders into one program, which is covered on our condo association services page.

Frequently Asked Questions
How often should a hull be cleaned in the St. Lucie River?
Often less frequently than on the coast, and that is a real advantage of being up the river. Brackish water has lower salinity, so growth builds more slowly and many Stuart boats can safely run a five to eight week interval instead of four. Boats kept closer to the St. Lucie Inlet in saltier water foul faster. Bare gel coat with no bottom paint still needs attention every 10 days to two weeks wherever it sits.
How much does hull cleaning cost in Stuart?
Our standard retail rate is a $220 flat fee for vessels under 40 ft, then $5.50 per foot from 40 to 69 ft, $6.00 per foot from 70 to 99 ft, and $6.50 per foot at 100 ft and over. Condition and access can change a quote, and a first clean on a neglected hull is a bigger job than the cleanings that follow. Full detail is on our hull cleaning prices page.
Can you help if I am just passing through on the Okeechobee Waterway?
Yes, and a good share of our Stuart work is exactly that. You do not need a home marina here, a membership, or an existing account. Tell us where the boat is, whether that is a mooring in Manatee Pocket, a slip on the St. Lucie River or a spot mid-transit, and we will get a diver to you.
Do you service private docks at Sailfish Point and along Hutchinson Island?
Yes. Private deepwater docks are serviced the same way as marina slips, and dispatch confirms gate and dock access in advance so the diver is not working it out on arrival. We also reach private residential docks well up the St. Lucie River.
Do you clean docks, pilings, seawalls and lifts as well as hulls?
Yes, and most Martin County waterfront properties end up on one combined schedule. Floating docks are usually cleaned every six weeks, fixed docks around every three months, boat lifts about every six months, and seawalls and dock pilings get cavitation cleaning roughly once a year. Putting them on one recurring calendar means one program to approve rather than separate calls.
Are you insured, and can you send a certificate of insurance to my marina or association?
Yes, on request and usually the same business day. We carry $3,000,000 in total per-occurrence liability, which is $1M/$2M general liability plus a $2M umbrella, plus Ship Repairers Legal Liability covering damage to the vessels we work on, and workers compensation and USL&H on every diver. Associations and marinas generally want that certificate on file before work starts.
What do I get after each cleaning?
After-photos with every invoice, taken by trained divers on professional underwater camera equipment, plus a written dive report for your logbook, insurer or marina, and a live GPS tracking link so you can see the crew arrive. Your card stays on file and is charged only after the service has been performed and documented.
