Stop Paying Divers to Scrape Away Your Bottom Paint.
Hull Shield's ultrasonic antifouling system protects your hull 24/7 - preventing barnacle and algae buildup, eliminating diver bills, and extending bottom-paint life 2-3.
Works on center consoles, sportfishers, trawlers, & yachts across the warm-water South & Gulf Coast.
How Ultrasonic Antifouling Stops Growth Before It Starts
The system sends safe, high-frequency pulses through your hull-creating microscopic vibrations that stop algae and barnacle larvae from attaching.
✅ Eco-Friendly: zero toxins or copper leaching into the marina.
✅ Easy Install: mounts inside the hull and connects to 12 V power - no through-hulls.
✅ Proven Results: extends bottom-paint life 1 to 2 year in warm-water zones.
✅ 24/7 Automatic Protection: runs quietly while your boat's in the water - no maintenance required.
