If you've noticed your boat sluggish out of the marina lately — or your fuel bills quietly creeping up — your hull might be trying to tell you something. Barnacles, slime, and marine growth don't knock before they move in. In South Florida's warm, nutrient-rich waters, they don't even wait long to get comfortable. Left unchecked, biofouling can increase drag by 20% or more, costing you real money every time you throttle up.
The good news: hull cleaning Fort Lauderdale services are widely available, and getting on a regular cleaning schedule is one of the smartest moves any boat owner can make.
Why Fort Lauderdale Hulls Foul Fast
Fort Lauderdale isn't just a boating town — it's one of the most active marine corridors on the East Coast. The Intracoastal Waterway, Port Everglades, and hundreds of private marinas mean boats are in the water year-round. And that's exactly the problem.
South Florida's water temperatures rarely dip below 65°F even in winter. Combine that with high salinity, abundant sunlight, and nutrient runoff from the Intracoastal, and you've created ideal conditions for barnacles, algae, zebra mussels, and tube worms to colonize your bottom paint within weeks.
Unlike boaters in the Northeast who haul out for winter and get a natural reset, Fort Lauderdale boat owners are in a constant battle against growth. If your boat sits in a slip for more than 30 days without a cleaning, you're already behind.
What to Look for in a Hull Cleaning Diver
Not all hull cleaning divers are equal. When you're hiring someone to go under your boat with a brush and scraper, you want to make sure they know what they're doing — and that they're not going to inadvertently strip your bottom paint or miss critical areas like props, shafts, and through-hulls.
Here's what to look for:
Experience and credentials: Look for divers with commercial diving certifications (PADI, NAUI, or equivalent). Membership in the Association of Diving Contractors International (ADCI) is a solid mark of professionalism. Ask how long they've been doing hull cleanings specifically — general dive experience doesn't always translate to good hull work.
Proper equipment: A quality hull cleaning diver should carry soft-bristle brushes for painted surfaces, separate tools for zinc anodes (no scraping the zincs!), and underwater lighting for dark slip conditions. If they're doing the job with just a mitt and a flashlight, keep looking.
Zinc awareness: This is a big one. Your zinc anodes sacrifice themselves to protect your metal fittings from galvanic corrosion. A diver who aggressively scrubs or chips at zincs can accelerate their wear. Make sure your diver knows to clean around zincs gently, not on them.
Liability insurance: Any reputable diving service should carry liability coverage. If something goes wrong — a prop nick, a scraped keel — you want recourse.
Transparent pricing: Hull cleaning in Fort Lauderdale typically ranges from $2–$5 per foot for light to moderate growth on a monohull. Heavier fouling, multihulls, or vessels with complex running gear will cost more. Get a quote upfront and clarify what's included (props, shafts, trim tabs, waterline scrub).
How Often Should You Schedule Hull Cleanings?
For most boats kept in Fort Lauderdale slips, the rule of thumb is every 4–6 weeks during warmer months (April through October) and every 6–8 weeks in the cooler season. That said, a few factors can change the equation:
- Antifouling paint type: Ablative paints wear down with use and need more frequent touch-up inspections. Hard paints can handle slightly longer intervals but need a thorough scrub when cleaned.
- How often you run the boat: A boat that gets out every weekend generates water flow that naturally slows growth. A boat that sits idle in a slip will foul faster.
- Slip location: Slips with strong tidal flow or good water circulation tend to see slower buildup. Stagnant marina pockets are worse.
- Recent haul-out: If you just had fresh bottom paint applied, your first hull cleaning Fort Lauderdale service should be a light one — you don't want to aggressively scrub fresh paint that's still curing.
A good diver will actually tell you after each cleaning how the growth looked and whether you can stretch your interval or should tighten it up. That feedback loop is valuable.
Questions to Ask Before You Hire
Before you hand over a deposit, run through these questions with any hull cleaning diver you're considering:
- Are you licensed and insured? Non-negotiable. Get the certificate if you want it.
- How do you handle zincs? They should immediately say "we clean around them, not on them."
- Do you photograph the hull before and after? The best divers document their work. Photos protect both parties and help you track growth trends.
- What do you do if you find something concerning — a cracked keel fitting, a failing through-hull? A professional will flag it. A fly-by-night will say nothing.
- Do you offer a maintenance schedule or reminder service? Some divers will set you up with recurring visits. Easier for you, better for your boat.
- What's your process for heavy growth? If they plan to use metal scrapers on antifouling paint, that's a red flag. Soft bristles and patience are the right approach.
- Can I see references or reviews? Established divers in the Fort Lauderdale market will have a track record. Ask for it.
Don't Wait Until You Can See the Growth
By the time barnacles are visible above the waterline or you're feeling that sluggishness at the helm, your bottom has already been fouled for a while. The best approach to hull cleaning Fort Lauderdale is prevention, not remediation — regular, scheduled cleanings before growth gets a foothold.
A fouled hull costs you in fuel, performance, and long-term damage to your paint and running gear. Regular cleanings are one of the lowest-cost, highest-return maintenance items for any Florida boat owner.
