Antifouling Paint - Depletion Rate
Antifouling paint depletion over a docking interval - self-polishing copolymer (SPC) loses ~5–15 µm/month depending on speed and trade area.
Annual depletion
78.9µm/yr
Coating life
3.17years
Formula, assumptions, and limits
Typical 60-month docking interval. Tropical/warm trades → higher polish rate + faster fouling. Laid-up vessels lose antifouling effectiveness even while polishing slows.
