We clean boat bottoms in Delray Beach every 30 days, in the Tropic Isle canals, at the Delray Beach City Marina south of Atlantic Avenue, at Delray Harbor Club and at private docks along the Intracoastal. Delray has no inlet, so every boat here spends a long time at the dock between runs to Boynton or Boca, and that is when the growth happens.

Hull cleaning in Tropic Isle and at the city marina

Tropic Isle's canals are deep, calm salt water off the Intracoastal, and a boat there grows a waterline band and slime between trips plus hard barnacles on the props, shafts and rudders, where bottom paint can't stick. The run to the Boynton or Boca inlet scrubs the hull, not the metal.

The city marina's 24 slips and Delray Harbor Club's docks sit on the Intracoastal in the 50-foot shoreline slow zone, in tidal water, and the boats there, liveaboards included, are cleaned in place.

The Delray Beach City Marina's 24 slips take boats from 30 to 55 feet, allow liveaboards and have a pump-out, and yacht cruises leave from Veterans Park just north of the Atlantic Avenue drawbridge. Delray Harbor Club Marina on South Federal Highway sits south of Linton Boulevard at about mile 1040. Three drawbridges, at George Bush Boulevard, Atlantic Avenue and Linton Boulevard, span the Intracoastal through the city, so a run to either inlet means bridge openings, and boats that don't feel like waiting sit at the dock instead, which is our business.

Delray boats wait for drawbridges at George Bush, Atlantic and Linton on the way to either inlet, and boats that wait tend to stay home, which is why Tropic Isle hulls grow the way they do. City marina liveaboards never move at all and show the heaviest waterline band in the city; the diver works under them with the owner aboard or ashore, whichever they prefer.

Delray Beach boats we clean sit on the Intracoastal Waterway. Delray Beach City Marina and Delray Harbor Club Marina: regular stops. Private docks in Tropic Isle and the Marina Historic District (ZIP codes 33444 and 33483) get the same 30-day visit.

What's included

  • Hull

    The whole hull surface, thru-hull fittings, underwater lights and every chine.

  • Running gear

    Props, thrusters, rudders, shafts, transducers and trim tabs, cleaned every visit. Tell us if Propspeed is applied: coated gear is handled by the coating maker's guidance.

  • Waterline

    The algae band at the waterline, removed with soft brushes.

  • Zincs

    Anode percentage checked every dive and replaced once it reaches 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.

How long it takes and how often. 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.

Full boat bottom cleaning guide

Boat Bottom Cleaning in Delray Beach: your questions

I live aboard at the Delray Beach City Marina. Can you clean under me while I'm on the boat?

Yes. The diver works from the slip, and you can stay aboard or step off; there is no need to move the boat. Liveaboards usually see the most waterline growth because the boat never runs, so 30 days is the maximum.

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.
