Anti-fouling and Boat Maintenance

Current UK anti-fouling controls are broader than the old shorthand that only TBT is banned. MCA MGN 398 Amendment 1 records that ships must not apply or reapply organotin compounds acting as biocides, and must not apply or reapply anti-fouling systems containing cybutryne. Existing coatings and survey or declaration duties have further vessel-specific provisions, so use a compliant system and obtain competent advice when a coating history is uncertain.

The RYA's practical sequence is Protect, Collect, Dispose. Protect the ground, water, drains, neighbouring boats and people before work begins. Collect wet scrapings, sanding dust, flakes, wash water and contaminated consumables at source. Dispose through the boatyard or local waste route specified for the material rather than leaving rain or wind to move it.

Follow the product's preparation, personal-protection, application and disposal instructions and the yard's rules. Dry sanding, pressure washing, solvents and cleaning products can each create a different exposure or waste stream. 'Biodegradable' or 'eco' marketing does not prove that a product may be released directly into the water; minimise use and keep residues out of the marine environment.
