My boat (SeaHunter 39) bottom was unpainted and dry stored in a rack. I decided to paint the bottom and keep it in a slip. This is in South Florida. I was skeptical of Sonihull but decided to try it. I launched the boat with a fresh paint job and newly installed sonihull. After a few months in the water I hauled the boat for service. The bottom had virtually no growth on it. A year later the sonihull box malfunctioned and I noticed immediate growth started to build. I pulled the box and sent it back to PYI. They replaced the box with a new one. I’m happy and my bottom is happy again. I now building a new SeaHunter 41 catamaran and installing two sonihull systems because it works!
