Hull scrubbing can lead to the build up of toxic chemicals in your local waters as well as the potential introduction of invasive species.

To ensure that both of these outcomes are prevented, limit hull scrubbing to safe spaces with lots of tidal circulation. If vessels are transiting to your event ask them to clean their hulls before arriving and again before departing.

If improperly contained, toxic emissions from maintenance activities such as hull cleaning can runoff directly into the water, damaging marine ecosystems. Prevent this by limiting maintenance activities during your event to onshore facilities with approved containment measures in place.

Conduct maintenance in approved and fully contained areas by ensuring that all wastewater generated from maintenance is treated and disposed of properly. Prevent toxic particles blowing into local waters by conducting maintenance in walled areas that are separated from the water. Use vacuum sanders to reduce dust and tarps to catch any paint scrapings or other maintenance byproducts.

To fulfill this Best Practice do at least one of the following:

  • Ensure all fiberglass sanding/fairing be contained and collected with dustless sanders or boatskirts.
  • Provide secure and enclosed location for all boat maintenance.
  • Do not allow boats with copper-based bottom paint to scrub while in the water.
