Pure, reliable water isn’t a luxury—it’s essential.

From the first rinse to the last refresh, water flows through every part of life onboard. Without the right system, even simple tasks become a chore. Our built-in water makers and water purifiers deliver ultra-pure, spot-free or freshwater for general use with ease—on demand, anywhere onboard.

Elevate your experience. Start with better water.

Double Power

Enjoy an XTC watermaker and ZTC Double Pass system in one common frame, so you can go from seawater to spot-free in one seamless purification process.

Simplify Your Rig

The combo system makes for easier installation and operation. Just turn on one device and the whole system goes to work creating true spot-free water.

Enjoy Efficiency

The XZ is less expensive than buying each system separately, and the way we’ve designed the combo takes up less overall space onboard your vessel.

Ultimate Purification

First, the watermaker removes 95-99% of solid content from seawater, and then the ZTC Double Pass kicks in, creating truly soft, pure, spot-free water.

Cruise in Comfort

Cook, clean food, drink and make ice-free of water-borne contaminants. Also, you can bathe, wash clothes and dishes, and more without concern for scaling, mildew, or lime build-up.

Travel Light

Enjoy efficient, cost-effective travel by not buying and transporting potable water. Save money, reduce the weight your vessel carries and free up valuable storage space on board.

Success Stories

What the Pros Have To Say

Real captains. Real results.

Karl Selter Captain

Justin Goldstein Captain – SOFI VI

CAPT. CASEY HUNT

74′ Spencer

“We’ve been using Spot Zero^® 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.”

CAPT. JOHN CRUPI

45m Dorothea III

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

CAPT. BART VAN DER HORST

125′ Westport

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

CAPT. KEN DRUMGOOLE

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.”
