Crossing Boundaries: Managing Invasive Species and Water Quality Risks for Coastal Boats Hulls in California and Baja California.

摘要

Fouling organisms that accumulate on boat hulls reduce vessel speeds and increase fuel consumption. Copper antifouling paints are widely used to slow the growth of hull-fouling species. Unfortunately, scientists, and regulatory agencies, have determined that copper leached from antifouling paints can accumulate in boat basins to levels that harm marine life. We conducted the research on which this report is based in order to determine costs and capacity of the boating industry (supply side) to provide California's coastal boat owners with supplies and services for controlling fouling on four broad categories of hull coatings: (1) copper antifouling paint (hereafter copper paint) and three alternatives, namely (2) zinc paint, (3) nontoxic epoxy hull coatings and (4) nontoxic slick hull coatings. Slick coatings include silicone and the more durable siliconized epoxy.
