CS-40 Marine Watermaker
The Evolution of Piston Pump Water Making
In 2006 Rich Boren began his journey in the Marine Watermaker world, when he built his own high-output piston pump watermaker for his family cruise aboard SV THIRD DAY, a 1978 Pearson 365 Ketch. Rich started with the need to build a simple and reliable watermaker to keep his wife and two kids comfortable while cruising Mexico’s Sea of Cortez. Word travels fast in the cruising fleet and before long other cruisers were first asking Rich to help them build their own and later to sell them a watermaker. So, from an anchorage in the Northern Sea of Cortez, Rich founded and soon became famous for his customer support at Cruise RO.
The Cruiser Services CS-40 piston pump watermaker, continues the evolution of piston pump watermakers with two decades of Rich’s real-world manufacturing , customer support and service experience. All the small details and “system wants” Rich wanted to incorporate into his own watermaker over the years are now a reality and come standard. With two decades of experience, years out cruising and living aboard, Rich knows what works and importantly what doesn’t work in the harsh marine environments. This allows Cruiser Services piston pump watermaker’s to have the Industry’s Best 4-Year Warranty, with complete 7-Day-A-Week technical support and service.
