Marine Water Makers
Marine Watermakers & Reverse Osmosis Desalination Systems for Every Vessel
A marine watermaker converts seawater into clean, drinkable fresh water onboard using reverse osmosis — giving you complete independence from dock water wherever you cruise. Whether you’re crossing oceans, anchoring in remote bays, or provisioning a superyacht at Port Everglades, the right watermaker means unlimited fresh water produced directly from the sea around you.
Yacht-Mate Products supplies marine watermakers for every vessel type and every level of use — from compact portable units for sailing yachts and cruising catamarans, to high-output systems producing thousands of gallons per day for motor yachts, charter vessels, and superyachts. Every unit we stock is engineered specifically for the marine environment, built to handle salt air, vibration, and the tight installation spaces typical of onboard systems. We supply and install from our Fort Lauderdale warehouse, with service support across South Florida and worldwide shipping on all products.
Blue Water Watermakers — Portable to High Output
The Blue Water range covers the full spectrum of recreational and professional marine watermaker requirements:
Clear Mate Mobile — portable reverse osmosis unit at $6,700. The #1 rated mobile RO system for spot-free rinse on demand. Ideal for vessels without a permanent watermaker installation or owners who move between boats.
ClearMate — compact installed Blue Water watermaker for smaller vessels and day boats requiring a permanent fresh water production solution.
Blue Water Express — 200–800 gpd output. Mid-range installed watermaker for cruising sailboats, motor yachts, and catamarans with moderate daily fresh water requirements.
Blue Water Express XT — 2,000 gpd output. High-volume production for larger motor yachts and vessels with high daily fresh water demand.
Blue Water Explorer — 475–1,800 gpd output. The Explorer series is designed for serious offshore cruisers and larger motor yachts requiring reliable, high-output fresh water production in remote locations.
Blue Water Explorer LX — 2,100–3,400 gpd output. High-capacity Explorer configuration for larger vessels and superyachts.
Blue Water Legend — 475–1,800 gpd. The Legend series delivers premium build quality and performance for motor yachts and superyachts where reliability and output consistency are the priority.
Blue Water Legend LX — 2,100–3,400 gpd. The highest-output Legend configuration for large superyachts and commercial vessels with demanding daily fresh water requirements.
Tecnicomar Watermakers — Commercial Grade for Superyachts
The Tecnicomar range is engineered for vessels where watermaker performance is a mission-critical operational requirement — superyachts, commercial vessels, and charter boats with large crews and high daily water consumption.
Tecnicomar BiCompact — duplex watermaker system producing 3,162–4,426 gallons per day across two configurations. Two fully automatic high-production RO units mounted in a compact stainless steel frame, operating in parallel or singularly. Carbon fibre pressure vessels (TÜV certified), automatic membranes washing cycle, and optional remote monitoring via LCD panel, on-board PC, touch-screen display, or GSM/SAT link. The professional standard for large superyachts, commercial vessels, and charter operations.
Additional Tecnicomar models are available across a wider output range — contact our Fort Lauderdale team for the full specification range and pricing.
Watermaker Accessories — Filters, Membranes & Pump Oils
A watermaker performs at its best with regular maintenance and correct consumables. Our Watermaker Accessories range covers the essential maintenance items every watermaker owner needs:
Pump oils — Cat Pump Oil 21oz for Cat Pump units and GP Pump Oil 16oz for General Pump units — the two most commonly fitted high-pressure pump types across marine watermakers.
Replacement pre-filters and membranes are stocked in our Fort Lauderdale warehouse for fast turnaround — contact us with your watermaker model and we’ll confirm the correct service parts.
Choosing the Right Marine Watermaker
Output capacity in gallons per day (GPD) is the starting point. A couple aboard a cruising sailboat may need 30–50 GPD. A crewed superyacht requires 500–3,000+ GPD depending on crew size and usage. Power source matters equally — DC systems suit sailboats and solar-equipped vessels; larger AC systems require a generator or inverter. Available installation space, noise level, and ease of maintenance are factors our Fort Lauderdale team will work through with you before you commit.

FAQ's
What is a marine watermaker?
A marine watermaker is a reverse osmosis desalination system that converts seawater into clean, drinkable fresh water onboard. It forces seawater through a semi-permeable membrane under high pressure, removing salt and contaminants — giving vessels complete independence from shore-based water supplies wherever they cruise.
How much water can a marine watermaker produce per day?
Output depends on the model. Compact units produce 200–800 GPD, mid-range systems 475–1,800 GPD, and high-output superyacht systems produce 2,000–4,000+ GPD. Yacht-Mate stocks Blue Water and Tecnicomar systems across this full range — contact our Fort Lauderdale team to size the right unit.
Do I need a generator to run a watermaker?
Not always. Compact DC watermakers run on 12V or 24V — suited to sailboats and solar-equipped vessels. Larger high-output systems require AC power via generator or inverter. Our team will advise on the right power configuration for your vessel and daily water requirements before you order.
Can I install a watermaker myself?
Simpler modular systems can be DIY-installed if you're comfortable with marine plumbing and basic electrical. Complex framed systems on larger vessels are best installed professionally. Yacht-Mate installs and commissions all systems we supply throughout South Florida — contact us to discuss your project.
How do I maintain a marine watermaker?
Flush membranes after each use and whenever the unit sits idle for more than a few days. Replace pre-filters on schedule and perform membrane cleaning based on run hours and water quality. Yacht-Mate stocks all replacement filters, membranes, and pump oils from our Fort Lauderdale warehouse.
