How often does a Miami boat need bottom paint?

Once a year for most boats that live in the water. Warm Biscayne Bay water grows fouling faster than almost any cruising area in the country. Trailer boats or boats kept on lifts can go longer between jobs, but in-water boats should plan on an annual bottom.

What is the difference between ablative and hard bottom paint?

Ablative paint polishes off as the boat moves, exposing fresh biocide. Cleaner at haul-out, better for boats that run frequently. Hard paint stays in place and holds up to trailering or racing, but requires more aggressive pre-splash cleaning. We recommend ablative for most Miami slip-kept boats.

Can you paint my boat where it sits or does it need to come out of the water?

Bottom paint requires the boat out of the water. We coordinate haul-out at partner yards in Miami, Coconut Grove, Miami Beach, and Fort Lauderdale based on your boat size. We handle the full job from haul through splash so you do not have to deal with the yard directly.

Do you fix blisters while the boat is out of the water?

Yes. Bottom paint timing is the best window to address osmotic blisters, gelcoat damage, or fiberglass repair. We inspect on haul-out and give you a written plan before work starts.

If your boat lives in the water in Miami, bottom paint is not optional. Warm, nutrient-rich water in Biscayne Bay grows barnacles, slime, and tube worms faster than almost any cruising ground in the country. A neglected bottom costs you 20-30% of your top speed and turns a simple scrape into a gouged-up mess. We handle the full bottom paint job from haul-out through splash.

Why Miami Boats Need Annual Bottom Paint

Most cruising grounds can get 2-3 years between bottom paint jobs. Miami is not one of them. Biscayne Bay's water temperature rarely drops below 70 degrees, even in January, and that warm water grows soft fouling (slime, algae, hydroids) in weeks and hard fouling (barnacles, tubeworms) in months. Annual bottom paint is standard for Miami boats that stay in the water.

Antifouling Paint Types

The right paint depends on how you use the boat. We walk you through the tradeoffs before we buy:

Ablative (self-polishing) paint: Releases biocide as the boat moves. Great for boats that run frequently. Cleaner at haul-out. Works: Interlux Micron CF, Pettit Ultima SR-60, Sea Hawk Cukote Biocide Plus.
Hard (modified epoxy) paint: Holds up to trailer boats, racing hulls, and boats that sit between uses. Needs more aggressive pre-splash cleaning. Works: Interlux Ultra-Kote, Pettit Trinidad, Sea Hawk Islands 77.
Hybrid / dual-biocide: Combines ablative polishing with extra cuprous oxide for hard fouling resistance. Popular in Miami for slip-kept boats.
Clear or metallic coatings: For performance boats that want minimal weight and drag. Shorter service intervals.

The Bottom Paint Process

Quality bottom paint is 80% prep. Here is what a proper bottom job looks like:

Haul-out and pressure wash: Remove loose fouling and old paint while it is still wet.
Bottom inspection: Check for blisters, gelcoat damage, or through-hull issues. Address any problems before painting.
Sand and prep: Scuff or fully sand old paint based on its condition. Feather edges where paint has chipped.
Mask and tape: Protect the boot stripe, running gear, and transducers from overspray and brush marks.
Barrier coat if needed: First-time painted hulls or hulls with blister history get a full epoxy barrier system.
Apply paint: Two coats minimum, three at the waterline. Roll and tip or spray based on paint type.
Splash: Paint needs to go into water within the manufacturer's splash window (usually 24-72 hours) for full biocide release.

Running Gear and Running Surface Work

Bottom paint is a great time to catch up on below-waterline maintenance. While the boat is hauled, we can also handle:

Zinc/aluminum anode replacement
Shaft, strut, and cutless bearing inspection
Propeller cleaning, balancing, or replacement
Through-hull and seacock service
Transducer cleaning or replacement
Rudder and trim tab service

Haul-Out Coordination

We coordinate haul-out at partner yards in Miami, Coconut Grove, Miami Beach, and Fort Lauderdale depending on your boat size. Boats up to 60 feet handle at most local marinas; larger sportfishers and yachts splash at the bigger yards in Dania Beach and Fort Lauderdale. We handle the yard booking, transportation, paint ordering, and full job so you never have to juggle vendors.

Miami Bottom Paint Specialists

Why Miami Demands Annual Bottom Paint

Biscayne Bay water stays warm year-round, and warm water grows aggressive marine fouling. Slime and algae appear in weeks, barnacles and tubeworms in months. A neglected bottom costs 20-30% of your top speed, burns more fuel, and turns simple scrapes into gouged hulls. Our team handles Miami bottom paint timing, paint selection, and haul-out coordination for boats of every size across Dinner Key, Miami Beach Marina, Haulover, and the Fort Lauderdale yards.
