Let’s dive in.
What Makes a Watermaker Essential for Cruising Sailors?
The Freshwater Challenge on Extended Passages
Most cruising sailboats carry between 75-200 gallons of freshwater. That’s enough for approximately 5-10 days for a couple practicing conservative usage. On passages exceeding this duration, sailors face three options:
- Severe rationing (uncomfortable and unsustainable)
- Deviating from optimal routes to reach refill ports (adding expense, time, and risk)
- Installing a watermaker (achieving freshwater independence)
Modern reverse osmosis watermakers convert seawater into drinking-quality freshwater by forcing saltwater through a semi-permeable membrane at high pressure. This process removes 99%+ of salt, bacteria, and contaminants.
Beyond Convenience: Safety and Range Extension
“Our watermaker isn’t just about comfort. It’s fundamentally changed our cruising capability,” explains Sarah Chen, who completed a circumnavigation aboard her Hallberg-Rassy 46. “We can now confidently plan routes based on weather and currents, not freshwater availability. During our Indian Ocean crossing, we had sufficient water for daily showers, laundry, and even rinsing the deck to remove salt buildup.”
For liveaboards and long-distance cruisers, a dependable watermaker provides:
- Extended offshore capability (weeks or months without shore access)
- Reduced dependency on marina infrastructure (saving thousands annually)
- Health and hygiene (proper hydration and sanitation in tropical climates)
- Vessel longevity (freshwater rinse-downs prevent corrosion)
- Emergency backup (critical if shore infrastructure fails post-storm)
Critical Factors: How We Evaluated These Watermakers
Our evaluation prioritized the real-world demands of offshore cruising, not just manufacturer specifications. Here’s what we examined:
1. Reliability in Harsh Conditions
Marine environments are unforgiving. Temperature extremes, constant motion, saltwater exposure, and humidity destroy lesser-built systems. We focused on systems proven aboard vessels operating in:
- Tropical heat (Red Sea, Caribbean)
- Cold water environments (Patagonia, North Atlantic)
- Extended offshore passages (Pacific crossings, circumnavigations)
2. Energy Efficiency
Most cruising sailboats rely on solar, wind, or limited generator power. Energy consumption directly impacts system usability. We measured:
- Amps drawn at 12V/24V (critical for battery sizing)
- Run-time required to produce daily water needs
- Compatibility with renewable energy systems
3. Maintenance Accessibility
In remote anchorages, you’re your own technician. Ideal systems feature:
- Simple, logical component layout
- Minimal specialized tools required
- Parts availability through international shipping
- Clear documentation and troubleshooting guides
4. Serviceability and Parts Availability
“We chose our watermaker specifically because parts could be shipped to obscure South Pacific islands,” notes Marcus Andersson, who cruised for six years aboard his Ovni 435. “When our high-pressure pump needed replacement in Vanuatu, parts arrived within 10 days. That wouldn’t have been possible with some European brands.”
5. Build Quality and Engineering Standards
We prioritized systems manufactured to recognized international standards (NEMA, ASTM, NSF, ISO) with:
- Corrosion-resistant components (316 stainless steel, marine-grade plastics)
- Quality control processes
- Engineering pedigree and company longevity
6. Production Capacity vs. Vessel Size
Watermaker output must match consumption patterns:
- Small cruisers (30-40 feet, 2 people): 6-12 gallons/hour
- Mid-size cruisers (40-50 feet, 2-4 people): 12-20 gallons/hour
- Larger vessels (50+ feet, 4+ people): 20-40+ gallons/hour

Key Considerations When Choosing Your Watermaker
1. Calculate Your Actual Water Consumption
Before selecting a system, realistically assess your daily freshwater needs:
Typical Daily Consumption (2-person crew):
- Drinking/cooking: 2-3 gallons
- Dishwashing: 2-3 gallons
- Personal hygiene: 4-8 gallons
- Deck washing/misc: 2-4 gallons
- Total: 10-18 gallons/day
Add 30-50% for comfort margin and guest capacity. A 15 GPH watermaker produces this volume in approximately 1-1.5 hours of operation. This is reasonable for most solar-powered systems.
2. Assess Your Energy Budget
Map your vessel’s energy ecosystem:
- Battery capacity (amp-hours available)
- Charging sources (solar wattage, wind generation, alternator output, generator)
- Other electrical loads (refrigeration, autopilot, instruments, etc.)
Ensure your watermaker can operate within your renewable energy production or that you’re prepared to run a generator during production cycles.
3. Plan for Installation Space and Accessibility
Watermakers require:
- Pump/membrane module: 12-24″ length, 6-10″ diameter (varies by model)
- Pre-filters: Housing for sediment and carbon filtration
- Through-hull fittings: For seawater intake
- Freshwater plumbing: Connection to tanks or direct use
- Electrical connections: Properly sized wiring and circuit protection
Critically, installation should allow reasonable access for maintenance. Systems buried behind inaccessible panels become maintenance nightmares.
4. Understand Maintenance Requirements
All watermakers require periodic maintenance:
- Pre-filter replacement: Every 3-6 months (varies with water quality)
- Membrane cleaning: 6-12 months or when production declines
- Membrane pickling: If system unused for extended periods (weeks/months)
- High-pressure pump service: Every 1,000-2,000 operating hours
- System cleaning: Annual or as needed
Select a system with clear maintenance procedures, readily available parts, and documentation you can actually understand.
5. Consider Long-Term Total Cost of Ownership
The cheapest watermaker isn’t always the most economical:
Budget System: $3,500 initial + $400/year parts + early replacement (5-7 years) = $7,300 over 10 years (requiring mid-term replacement)
Premium System: $8,500 initial + $300/year parts + long lifespan (15+ years) = $11,500 over 15 years
When factored across realistic lifespans, premium systems often deliver superior value while providing greater reliability when you need it most.
Installation Tips from Experienced Cruisers
Professional vs. DIY Installation
Consider Professional Installation If:
- You’re uncomfortable with through-hull installations
- Electrical work exceeds your skill level
- System complexity warrants expert setup

Greg Wilson, SV Wind Song, Island Packet 38
Critical Installation Considerations
✓ Seawater Intake Placement: Position through-hull where clean seawater is accessible, away from hull-speed turbulence and shallow enough to avoid sediment.
✓ Pre-Filter Accessibility: You’ll service these frequently. Ensure easy reach.
✓ Secure Mounting: Marine environments are violent. All components must be rigidly secured to prevent movement and vibration damage.
✓ Proper Wiring: Use marine-grade wire, appropriate gauge for amperage, with proper circuit protection (fuses/breakers).
✓ Freshwater Plumbing: Consider both filling tanks and “direct use” capabilities for immediate production access.
Maintenance Best Practices for Watermaker Longevity
Routine Maintenance Schedule
Before Each Use (if not used recently):
- Flush system with freshwater
- Check pre-filters for cleanliness
- Verify no leaks or unusual sounds
Every 50 Operating Hours (or quarterly):
- Replace sediment pre-filter
- Inspect all connections for leaks
- Check high-pressure gauge readings (declining performance indicates membrane fouling)
Every 6-12 Months:
- Replace carbon pre-filter
- Clean or replace membrane if production has declined >20%
- Inspect high-pressure pump for wear
- Test product water quality (TDS meter)
Extended Storage (2+ weeks unused):
- Pickle membrane with preservative solution
- Follow manufacturer’s storage procedures
Troubleshooting Common Issues
Low Production/High Pressure:
- Cause: Membrane fouling, clogged pre-filters
- Solution: Replace pre-filters, clean/descale membrane
Salty Product Water:
- Cause: Membrane damage, insufficient pressure
- Solution: Test membrane, verify pump pressure, possibly replace membrane
Pump Cycling/Unusual Noise:
- Cause: Air in system, low inlet pressure, pump wear
- Solution: Bleed system, check inlet strainer, service pump
“The most important maintenance lesson I learned: Don’t defer filter changes. A $15 pre-filter protects a $800 membrane. I got lazy in the South Pacific and paid for it with premature membrane replacement.”
Stephanie Morales, SV Odyssey, Hallberg-Rassy 43
Real-World Testimonials from Long-Distance Cruisers
Pacific Crossing Perspective
“We departed San Diego for the South Pacific with an ECHOTec watermaker aboard our Tayana 42. Over 8,000 miles and six months of cruising through French Polynesia, the Cook Islands, and Tonga, our system performed flawlessly. Making 12 gallons daily took about 50 minutes and was easily powered by our solar array. The psychological freedom of unlimited freshwater transformed our cruising experience. We could wash the salt off daily, keep the boat clean, and never worried about reaching the next water source.”
Paul & Sandra Kim, SV Trade Wind, Tayana 42
Circumnavigation Experience
“During our three-year circumnavigation covering 37,000 nautical miles, our ECHOTec watermaker was indispensable. From the South Pacific to Southeast Asia, across the Indian Ocean, through the Red Sea, and across the Atlantic, our system faced extreme temperature variations, occasionally dirty water, and constant use. We performed basic maintenance (filter changes, annual membrane cleaning) ourselves, even in remote locations. The system never failed us. When planning our circumnavigation route, watermaker reliability was non-negotiable, and ECHOTec delivered completely.”
James Thornton, SV Resolute, Hans Christian 43
Caribbean Liveaboard Life
“As full-time liveaboards in the Caribbean for six years, our watermaker runs 4-5 times weekly. We’ve experienced everything from crystal-clear Bahamas water to murky mainland anchorages. The system handles varying conditions well with proper pre-filtration. Regular maintenance keeps it running smoothly, and when we needed technical advice, manufacturer support responded promptly even to our remote island location. For liveaboard life, a reliable watermaker isn’t luxury. It’s essential infrastructure.”
Michelle & Robert Garcia, SV Serenity, Beneteau 473

- Professional Installation: $1,500-4,000 depending on system complexity, location access, and local labor rates
Total project cost = System price + installation + commissioning/testing
How long do watermaker membranes last?
Membrane lifespan depends on water quality, operating hours, and maintenance:
- Well-maintained systems in clean water: 5-7 years or 3,000-5,000 hours
- Moderate conditions with regular cleaning: 3-5 years
- Challenging conditions (turbid water, irregular maintenance): 2-3 years
Proper pre-filtration and regular membrane cleaning dramatically extend lifespan. A $15 pre-filter change protects an $800 membrane investment.
Can I run a watermaker while sailing?
Yes, most watermakers can operate while underway, though considerations include:
- Heeling angle: Excessive heel may affect pump performance or introduce air
- Water intake location: Ensure clean water access at speed
- Power availability: Alternator charging or generator operation while sailing
- Sea state: Rough conditions may stress components; some cruisers prefer operating in calmer conditions
Many cruisers prefer making water at anchor using solar power, avoiding generator operation and conserving motion-sailing energy.
What’s the difference between AC and DC watermakers?
DC Watermakers (12V/24V):
- Pros: Operate directly from battery bank, compatible with solar charging, no generator required
- Cons: Higher current draw, require substantial battery capacity, potentially less efficient for very high production
AC Watermakers (110V/220V):
- Pros: More efficient for high-capacity systems, smaller current draw from alternator/generator
- Cons: Require generator operation or large inverter, fuel consumption for generator
Most cruising sailboats under 50 feet prefer DC systems for renewable energy compatibility. Larger yachts with significant generator usage may choose AC systems.
How much power does a watermaker use?
Power consumption varies widely by system design:
- Ultra-efficient (Spectra): 7-13 amps @ 12V (85-155 watts)
- Standard DC systems: 20-40 amps @ 12V (240-480 watts)
- AC systems: 3-8 amps @ 110V (330-880 watts)
For comparison, producing 15 gallons typically requires:
- Spectra: ~100-150 amp-hours from batteries
- Standard DC: ~150-250 amp-hours
- AC system: ~3-5 hours generator runtime or equivalent inverter load
Size your solar array and battery bank accordingly.
Can I make water directly from the ocean anywhere?
Watermakers handle saltwater effectively but considerations include:
- Water clarity: Turbid or silty water requires robust pre-filtration
- Pollution: Avoid industrial harbors, wastewater discharge areas
- Oil/fuel contamination: Can damage membranes permanently
- Biological growth: Algal blooms may clog filters rapidly
Best practice: Position intake where clean, offshore water is accessible. In questionable locations, skip watermaker operation and use tank reserves until reaching cleaner water.
