As climate change transforms our oceans, watermaker technology must evolve. Discover how rising salinity, temperature fluctuations, and microplastic pollution impact desalination systems – and what ECHOTec is doing to future-proof water security.
The Challenge of Fresh Water on Small Boats
For owners of small boats or yachts, the open water promises freedom – but only if your basic needs are covered. Freshwater tops that list. With limited space on smaller boats, finding a compact watermaker is essential for long trips. It should fit without taking up storage or overloading your power supply.
At ECHOTec Watermakers, we have seen a rise in demand for space-saving desalinators. More sailors, weekend adventurers, and liveaboards want sustainable, off-grid water solutions.
The challenge? Engineering water desalination systems that deliver on three critical requirements:
- Compact size that works in tight spaces
- Energy efficiency compatible with limited power sources
- Reliable output to meet daily freshwater needs
Thanks to recent innovations, today’s compact watermakers prove you don’t need a big boat to achieve water independence.
Space-Saving Solutions: Installing Watermakers in Tight Quarters
On a 25- to 35-foot sailboat, every inch counts. Gear, provisions, and crew all compete for limited space. Traditional desalinators were often large and complicated, like trying to fit a refrigerator in a small apartment.
Modern compact watermakers fix this issue with a modular design. They break down into smaller parts that can fit in unused spaces
- Beneath berths or bunks
- Inside lazarettes or lockers
- Vertically mounted along bulkheads
- In engine compartments
Our ECHOTec DML-200-1 is small, measuring only 24″ × 16″ × 8″. It can make up to 10 gallons of fresh water each hour. This is enough for drinking, cooking, and a quick rinse after swimming.
The modular approach delivers another crucial benefit: easier maintenance. Sailors can change filters or check valves without taking apart the whole system. This is important when working in tight spaces.
Power Efficiency: Desalination Without Draining Your Batteries
On small vessels, energy is precious. Whether you rely on solar panels, a limited battery bank, or a small generator, an inefficient water desalination system can quickly drain your reserves, leaving you with empty tanks and dead batteries.
Our compact watermakers incorporate several power-saving technologies:
Feature | Benefit |
High-efficiency triplex plunger pumps | Generate necessary pressure while consuming less power |
Low-RPM operation | Reduces energy demands during water production |
Energy recovery systems | Capture and reuse pressure energy that would otherwise be wasted |
Marine-grade lightweight materials | Minimize overall system weight and power requirements |
Many of our 12/24 Volt DC models, including the AML series, can produce fresh water using solar energy alone, ideal for sailors embracing sustainable cruising or navigating remote routes where fuel resupply isn’t guaranteed.
Water Output: How Much Can You Expect?
A compact desalinator is only practical if it meets your daily water needs. The average crew of two typically uses 5-10 gallons daily for:
- Drinking (1 gallon per person)
- Cooking (1-2 gallons)
- Basic hygiene (3-5 gallons)
- Occasional freshwater rinses (1-2 gallons)
Our compact watermaker lineup addresses various needs:
- ECHOTec AML Series: 13-70 gallons per hour, perfect for solo sailors or minimalist cruisers
- ECHOTec DML-200-1: Up to 10 gallons hourly, ideal for couples or small families
- ECHOTec DML-260-1: Delivers 13 gallons each hour while maintaining a compact footprint
Thanks to new RO (reverse osmosis) membrane technology and better filters, these systems clean saltwater more efficiently. This ensures you always have safe, great-tasting water.
Can You Drink Sea Water If You Boil It?
Many boaters wonder: “Can you simply boil seawater instead of installing a watermaker?”
The short answer: No. Boiling seawater only eliminates bacteria and biological contaminants, it doesn’t remove salt. Drinking boiled seawater remains dangerous, accelerating dehydration as your body struggles to process the high salt content.
This is precisely why a proper desalination system is essential for offshore cruising. Through reverse osmosis technology, ECHOTec watermakers remove:
- 99.4% of dissolved salts
- Bacteria and viruses
- Heavy metals
- Other harmful contaminants
The result is crystal-clear, safe drinking water without the health risks of improvised methods.
Sustainability: The Hidden Benefit of Onboard Watermakers
Compact watermakers deliver more than convenience – they support a more sustainable boating lifestyle. With environmental awareness growing in the boating community, more sailors are installing desalination systems to:
- Eliminate dependence on single-use plastic water bottles
- Reduce reliance on marina water supplies (which often use chlorine and other chemicals)
- Decrease the carbon footprint associated with transporting water to marinas
When paired with renewable energy sources like solar panels or wind generators, compact watermakers enable true self-sufficiency. Imagine crossing an ocean using the sun’s power. Your ECHOTec system quietly turns seawater into fresh water whenever you need it.
Our systems are made to last. We use high-quality, corrosion-resistant parts that can handle tough marine conditions for years of reliable service.
Why Compact Watermakers Transform Small Vessel Cruising
For small vessel owners, a compact watermaker is the the key to true freedom on the water. Whether you’re:
- Living aboard full-time
- Weekend cruising to remote anchorages
- Planning extended offshore passages
- Exploring regions with limited infrastructure
Having fresh water on demand fundamentally changes your relationship with your boat and the cruising experience.
Recent innovations in modular design, energy efficiency, and membrane technology mean even the smallest vessels can enjoy water independence. No more lugging heavy water jugs from the dock. No more rationing showers. No more planning routes around water availability.
