Florida’s environmental rules for in-water cleaning

Short answer: In-water cleaning in Florida is shaped by environmental best practices aimed at minimizing biocide release from bottom paint and preventing the spread of invasive marine growth. The practical answer is gentle, paint-preserving cleaning — which is good for the water and your hull alike.

Cleaning a hull in the water touches on real environmental concerns, and responsible divers take them seriously. The encouraging part is that the environmentally sound approach is also the approach that’s best for your boat.

The two main concerns

Regulators and the marine community focus on two things. First, biocide release: scrubbing antifouling paint too hard can shed copper and other biocides into the water, so light cleaning that preserves the paint is preferred. Second, invasive species: marine growth can carry organisms that spread between waterways, which is another reason to keep hulls clean and growth from ever getting established.

Why gentle is the answer

Both concerns point to the same practice: clean often and clean lightly. Removing a thin film with soft media barely disturbs the paint and keeps biocide in the coating where it belongs. Letting growth harden and then blasting it off is what releases the most paint into the water. The environmentally responsible method and the paint-preserving method are one and the same.

A note on staying current

Environmental guidance evolves, and rules can differ by waterway and marina. We follow current best practices for soft, paint-conscious in-water cleaning, and because all of our work is done in the water with no haul-out, there’s no boatyard runoff involved at all. If your marina or waterway has specific requirements, we’re glad to work within them.
