What Is Self‑Eroding Antifouling?
Self‑eroding antifouling is designed to gradually wear away through water movement. As the surface layer erodes, fresh biocides are exposed, helping to keep fouling at bay throughout the season. By the end of the year, much of the coating has worn off, leaving far less build‑up on the hull.
Why Choose a Self‑Eroding Formula?
This type of antifouling is ideal for boat owners who want low‑maintenance protection. Because the coating continually sheds, you avoid the heavy paint build‑up that can accumulate with hard antifoulings. This in turns to the annual antifouling prep being far easier.
Self‑eroding antifouling is best suited to:
- Cruising yachts and sail boats
- Moderate‑speed vessels that don’t place extreme stress on the coating
- Owners who prefer minimal sanding and scraping between seasons
When It’s Not the Right Choice
High‑speed craft and performance‑focused boats may find that a self‑eroding coating won’t last a full season. The increased water flow with vessels that go at speed accelerates the rate in which paint will erode. In those cases, a hard antifouling paint is usually the better match.
