The NOXX system is not a new system, it's been around for over 30 years. It is just new to the recreational side of boating as of now. The NOXX system uses a low frequency pulse that creates the illusion of a predatory environment for Mussels, Barnacles and Pinworms, etc who then want to avoid your vessel completely. There is no negative environmental impact on marine life from the NOXX system. Using this system prevents early haul outs, prevents hard growth on your hull and preserves your paint for many years. This system is time proven with BC Ferries, Princess Cruise Lines, Washington State Ferry to name a few. It works beautifully on metal, wood and fiberglass hulls. This NOXX system can be installed while your boat is in the water.
