Being cruisers ourselves, we understand the challenges of powering a large-capacity water maker aboard a cruising vessel. This is why we developed the revolutionary idea to design our SeaMaker 20 and 30-gallon-per-hour water makers. Our RO water systems for sale operate on the power produced by a cruising staple, the Honda EU2000i generator or small diesel genset. 

Having the ability to produce 20 or 30 gallons of freshwater per hour changes everything. It makes daily showers for the crew, freshwater deck, and gear wash-downs while at anchor a possibility. Moreover, even a fresh water anchor chain wash-down and fresh water flushing heads are now a reality. Water on-board is not a luxury; it’s a necessity. With our water makers, it’s no longer a possibility exclusive for the Mega-yacht crowd but for the average cruiser.

We have a big boat with even bigger Lewmar ST65 winches! Furling out the in-mast main and mizzen along with the huge Genoa on our Hudson Force 50 has always been a “Captain Only” job due to the strength needed. But now with the WinchRite, I can direct the action from the cockpit while my two teenage kids work the winches. Using and loving the product myself, I approached the owners of WinchRite at the Long Beach Boat Show. Since then, CruiseRO has added the WinchRite to our selection of quality cruising gear.


We have looked and you simply won’t find a more feature-packed boat Battery Charger for the money. As cruisers, we only offer the highest quality products we trust ourselves. And when it comes to these battery chargers, we actually have one aboard our own boat.

These Marine Grade, Power Factor Corrected Marine Battery Chargers set a new standard of what you should expect from your battery charger. They offer effective features, high performance, and affordable prices. Years of experience in the battery charging industry has provided us the insight to include everything we could possibly think of and combine it all into one product. 

This exceptionally efficient power factor-corrected battery charger runs on any global AC power source between 90-270 volts (freq 40- 70Hz). The unit requires less input power, liberates less waste energy, and is still remarkably lightweight with a small footprint. Explore our boat battery charger selection for the one that best meets your needs.


CruiseRO originated from our founder’s concern about the lack of affordable and adaptable RO water systems for sale on the market. This concern led him to build his very own water maker to accommodate his water needs while going on a 4-year-long sailing trip. 

If you’re looking to buy a reverse osmosis system, a custom system might be exactly what you need. We can build a custom water maker to fit your specific application or we can retrofit your existing water maker with non-proprietary parts.

We have the experience and expertise to build custom RO systems for sale that suit your specific application or installation needs. We work with clients all the time who either already have some water maker parts or even a working water maker to complete or upgrade their current system. 

The client in the below photos was not happy with the performance or output of his Spectra water maker. Reusing some of his Spectra parts to save costs, we were able to turn his low-output DC water maker into a 30-gallon per hour 120v AC high-output water maker.
