The most hassle-free scheduled bottom cleaning in South Florida

The warm waters of South Florida cause the most extreme marine growth in the world. This growth can cause decreased speed and fuel economy, clog thru-hull intakes, and damage your ship's hull. We pride ourselves in providing the best and most hassle-free scheduled bottom cleanings.

Having your hull cleaned and maintained regularly is extremely necessary here. Thru-hull fittings can become clogged and destroy water makers, live wells and A/C units. Bottom paint cannot adhere to the metal running gear of your boat, so growth accumulates fastest in these vital areas. Most importantly, along with regular cleanings we are your eyes and ears under the water and can spot damage and problems before they end up costing you more.

What's included every month

Every monthly visit covers the whole boat below the waterline, and you get the proof.

  • Hull

    Cleaning of the entire surface of the hull including any thru-hull fittings, underwater lights, and all chines.

  • Running gear

    Deep cleaning of all propellers, thrusters, rudders, driveshafts, transducers, thru-hull fittings and trim tabs, every visit. Tell us if Propspeed is applied: coated gear is handled by the coating maker's guidance.

  • Waterline

    Thick algae grows constantly on the waterline where the sunlight is strongest. We use soft brushes to remove it while doing no damage to your hull.

  • Zinc replacement

    Zinc anodes prevent electrolysis on your boat and degrade doing it: depending on the electrolysis around your dock they last 3 to 13 months. Checked every dive, replaced at 50%.

  • Monthly dive report

    A report including your zinc percentage and bottom paint condition with every cleaning.

  • Photos every visit

    Detailed, high quality photos of your hull and running gear with every one of our monthly visits.

Why it matters

Benefits of monthly hull cleaning

  • Fuel economy: the accumulation of marine growth such as algae, barnacles and other organisms on the hull creates drag and increases resistance in the water. The result is reduced fuel efficiency and increased fuel consumption.
  • Speed and performance: a clean hull improves the speed and overall performance of a boat. By reducing drag, the vessel can achieve higher speeds and maneuver more easily.
  • Damage prevention: barnacles and other burrowing marine organisms can cause serious damage to your hull. Monthly cleaning also extends the life of your bottom paint and gelcoat.

These photos and videos keep our customers confident their investment is in the best hands and is getting a quality, thorough cleaning every time. See what hull cleaning costs and how the monthly plan works.

How it works

45 minutes to 4 hours per cleaning, depending on growth and boat length. Every 30 days for a boat that stays in the water; every two weeks in nutrient-rich spots or for a hull without bottom paint.

  1. Get a quote

    Boat length, where it is docked, bottom paint or not. Length sets the dive time; paint sets the schedule.

  2. First dive

    Hull, running gear and waterline cleaned with Ultra-Cavitation, zincs checked, report and photos sent.

  3. Monthly from then on

    The scheduling system tells you when the diver is coming; you don't need to be there. Monthly billing; zincs swapped at 50%.

What the dive report shows

A written dive report and photos come with every cleaning.

  • Zinc percentage per anode; replacement at 50%.
  • Bottom paint condition, so the next haul-out is planned, not guessed.
  • Photos of the hull and running gear.
  • Anything the diver spotted: clogged thru-hulls, damage, loose gear.
  • Detailed photos of the hull and running gear with every monthly visit, so you can compare month to month.

The report arrives after every cleaning whether or not you were there. Over a few months it becomes a history of your slip: how fast the zincs go, how the paint is holding up, and anything the diver spotted. Read more about zinc replacement at 50% and the bottom-paint guide.

Hull cleaning questions

How often should a boat bottom be cleaned in South Florida?

Every 30 days if it sits in the water, every two weeks in nutrient-rich areas or without bottom paint: barnacles adhere to gelcoat faster and thicker than to paint and can blister it if left too long.

Does the owner need to be there for the cleaning?

No. The diver works from your dock or slip without you; the report and photos arrive afterwards and billing is monthly. Behind a gate, the divers call ahead and send a text right before the visit. If you are around, they will walk you through what they found.

Will cavitation cleaning damage my bottom paint or Propspeed?

No. Ultra-Cavitation lifts growth with collapsing bubbles at far lower pressure than a pressure washer, with no scraper touching the surface: 100% non-abrasive on sound paint and gelcoat at the right standoff. Propspeed-coated gear is handled by the coating maker's guidance (soft cloth, no abrasives, no direct high-pressure water); tell us it is applied.

Are you licensed and Insured?

Yes. We carry $2,000,000 liability insurance through Fisk Marine Insurance.

How often should I get my zincs changed?

Depending on the electrolysis in the water around your boat, zinc anodes last anywhere from 3 to 13 months, so we do not go by the calendar: every anode is checked on every monthly dive, the percentage goes on your report, and we replace zincs once they reach 50%.
