Bottom Paint, Antifouling & Hull Care

Protect Your Investment Below the Waterline
A well-maintained hull is essential for performance, fuel efficiency, and long-term vessel protection. Our bottom paint and hull care services help prevent marine growth, reduce drag, and protect your vessel from the harsh conditions of the Pacific Northwest.
Whether your boat requires routine antifouling maintenance, a complete bottom paint renewal, or underwater running gear protection, our experienced technicians deliver professional results using proven marine coatings and preparation methods.
