74′ Spencer

“We’ve been using SpotZero for 8 years and I can’t imagine life without it. It pays for itself in the first 6 months. We’re saving a ton by not hauling 50 cases of water and not having to shammy, wax, and repaint the boat every few years.”


45m Dorothea III

“Running an expedition yacht that travels over 20k miles per year, I consider SpotZero systems to be part of our critical equipment onboard and I wouldn’t build a boat without one.”


125′ Westport

“Our cleaning routine used to be so inefficient. With the SpotZero system, it’s saving us 6-8 hours per washdown. We’ve also saved over $10,000 just in bottle water.”


70′ Hatteras Sportfish

“Our boat was new in 2015 and we haven’t had to polish it even once. It’s been pretty impressive not getting the hard water build-up on the boat. We evaluated several models when building our boat. Nothing compares to the Spot Zero water system.”
