From the shipyard in the UK to the shores of Ibiza — refining my sandblasting technique while removing antifouling from two sailboats.
Why Choose Wet Sandblasting for Removing Old Antifouling?
✨ 1. Faster & More Efficient
Wet sandblasting removes layers of old antifouling quickly and evenly. No endless scraping, no patchy results—just a clean hull ready for a fresh start.
💨 2. Improves Boat Speed
A smoother hull = less drag.
Removing rough, built-up antifouling reduces resistance in the water, helping the boat glide faster and handle better.
⛽ 3. Better Fuel Efficiency
Lower drag means the engine doesn’t work as hard. Motorboats often see noticeable fuel savings after a clean, properly prepped hull.
🌱 4. More Environmentally Friendly
The added water helps trap dust and paint particles, reducing airborne pollution and keeping harmful debris contained. Marinas love it because it’s cleaner and safer.
🛡️ 5. Gentle but Effective
Compared to dry blasting, wet sandblasting is less aggressive on the hull surface. It removes coatings without overheating or damaging the gelcoat.
🔧 6. Ideal for Both Sailboats & Motorboats
Whether you’re chasing speed under sail or fuel savings with an engine, a clean hull benefits every type of boat.

Recommendations
✔ Choose a professional with marine experience—hull materials differ, and correct grit and pressure matter.
✔ Follow up with proper surface prep (washing + drying) before applying new antifouling.
✔ Do it regularly—a clean, smooth hull is key to maintaining performance and efficiency season after season.
