The Pacific NW Boater research vessel, a ’79 Cheoy Lee 46 LRC, has a Coppercoat bottom job professionally applied at Townsend Bay Marine in Port Townsend. Coppercoat is a 10+ year epoxy-based anti-fouling. Non-leaching and non-ablative, Coppercoat is approved for use in the state of Washington. Worldwide, boats are routinely seeing 10-15 years without needing another bottom job, with some boats experiencing 20+ years of protection. Also applied as a DIY project, the manufacturer’s directions must be followed to achieve optimum results.
