Why You’d Want a Water Maker on Your Boat

The Definitive Lifestyle Guide: Why You Need a Water Maker on Your Boat

How desalination transforms freedom, comfort, and the very way you live afloat

There’s a moment familiar to many cruisers. You’re lying at anchor in a perfect bay — clear turquoise water, white sand, nobody else around. You reach for the shower tap, hesitate, and count seconds. “Just a rinse,” you tell yourself, “don’t use too much.”

That quiet hesitation defines life on many boats. Every drop of water is measured. Showers are rationed. Bed sheets are sticky with salt. And somewhere between refills and restrictions, the freedom of the sea becomes slightly limited.

A water maker changes that entirely. It shifts your relationship with the ocean — and your lifestyle aboard — in ways that go far beyond convenience.

​

1. From Restriction to Freedom

Without a water maker, the boat’s range is defined by your tanks. Your independence ends when the gauge hits empty. Even long-range yachts must eventually turn toward a tap.

Installing a marine RO system turns that equation on its head. Your range becomes, effectively, unlimited.

Suddenly you can stay in that perfect anchorage as long as you like. You can cruise the Kimberley, sail to Lizard Island, linger in the Louisiades, or cross to Indonesia — without needing to plan refills. The limiting factors become weather, fuel, or food, not water.

It’s not just freedom of distance — it’s freedom of time. A week can become a month. A layover can become a season. The boat stops being a traveller’s vessel and starts becoming a home.

​

​

2. Comfort Becomes a Daily Habit

When you make your own water, comfort stops being rationed and becomes normal.

Showers after swimming? Every time.
Washing dive gear? No guilt.
Rinsing decks, lines, and hatches? Routine.
Properly washing dishes instead of salt-rinsing them? A pleasure.

This shift seems small on paper, but day-to-day it’s transformational. Life aboard feels more civilised. You stop compromising. Your guests feel more at home. Crew morale rises because “saving water” no longer defines every decision.

Comfort on a boat isn’t luxury — it’s sustainability. It keeps people happy, clean, and sane on long voyages.

When you install a water maker, you start treating comfort as part of seamanship — because a comfortable crew is a capable crew.

​

3. Health and Hygiene — the Hidden Benefit

Many cruisers underestimate how much personal hygiene impacts long-term well-being at sea. Limited showers lead to skin irritation, salt buildup, rashes, and fatigue. Clean water helps you sleep better, feel fresher, and stay healthier.

And the quality of that water matters.

Marina water in remote regions can be heavily chlorinated, stale, or contaminated. A properly maintained RO system produces fresh, low-TDS water without hassle — water that’s safer and tastes better than most dock supplies.

For liveaboards, this is peace of mind in every cup.

​

4. Real Independence — Not Just Range

Ask any seasoned cruiser what they value most about their water maker, and they’ll use words like freedom, confidence, and independence.

When you make your own water, you become less reliant on infrastructure. You’re not dependent on questionable dock tanks, pipes or hoses or local village wells. You’re not at the mercy of a broken marina pump or a storm that shuts down the port.

Your boat becomes self-sufficient — a small, contained, working ecosystem. It draws from the sea and supports your life aboard completely.

This sense of autonomy changes how you plan, travel, and think. You stop timing your routes by logistics and start following weather, wind, and instinct.

​

5. Time Is the Real Luxury

Every refuelling or water stop is time you’re not cruising, resting, fishing, or diving. When you carry a water maker, you save hours — sometimes days — over a season.

• No more dinghy runs for jerry cans.

• No more queuing at marina taps.

• No more negotiating with local ports for potable water.

You reclaim time — the most valuable commodity on a boat. That’s what long-term sailors consistently praise: a water maker gives them back their days.

​

6. Mental Space: From Anxiety to Ease

Water anxiety is real. Even for experienced sailors, the subconscious worry about running out lingers — especially in remote anchorages.

Once you have desalination, that worry disappears. You no longer mentally calculate how much water’s left every morning. You stop checking the tank gauge daily. You relax.

That calm, steady confidence — the knowledge that you can make more anytime — is one of the most underrated benefits of owning a water maker. It doesn’t just change your routine; it changes your mindset.

​

7. Social and Environmental Freedom

Water makers also change how you interact with places and people.

You stop relying on overused island wells or local freshwater sources that communities depend on. That independence makes you a better guest — sustainable, low-impact, and self-contained.

Environmentally, a water maker reduces plastic waste. No bottled water runs, no empty crates. Many cruisers find that after installing one, their plastic waste drops by half. It’s cleaner for the ocean and simpler for you.

​

8. Community Insight — Lessons from Experienced Cruisers

Across countless cruising forums and discussion groups, veteran boaters repeat similar themes:

• Use it or lose it. The best systems are those run regularly. Freshwater flushes and frequent use keep membranes happy.

• Don’t overcomplicate. Simple, well-installed systems with good access and clear plumbing outlast over-engineered setups.

• Power planning matters. Match the water maker to your electrical system 

• Carry spares and know your system. Every serious cruiser carries spare filters, fittings and O-rings, They’re rarely stranded when something goes wrong.

• Once you have one, you’ll never go back. Owners say it again and again: “We can’t imagine cruising without it now.”

The lifestyle transformation outweighs the maintenance commitment for nearly everyone who crosses that line.

​

9. The Emotional Shift

Cruiser describe the first time they run their new system as “magic.” Watching seawater transform into clear, drinkable water is empowering. It’s practical science turning the ocean into life support.

But the real change happens quietly over months:

You start rinsing the boat daily. You start showering longer. You cook more freely. You anchor further from towns. You stop planning around scarcity.

Your boat stops feeling like a camp site — and starts feeling like home.

​

10. A Smarter Type of Luxury

Water makers aren’t flashy gadgets. They don’t sparkle on deck or sit idle on a coffee table. But among experienced cruisers, they’re considered the single most transformative comfort upgrade you can make.

It’s a subtle luxury: freedom from dependence. The hum of a machine below deck that gives you comfort, hygiene, and peace.

It’s the same idea as solar power or wind generation — a step toward a more independent, thoughtful way of cruising.

​

11. Who Needs One Most?

You don’t need to cross oceans to justify a water maker. It’s as valuable for coastal cruisers who spend weekends away from marinas as it is for circumnavigators.

You’ll benefit if you:

• Spend more than a night at anchor without resupply.

• Cruise in regions where freshwater is scarce or questionable.

• Have a large crew or guests aboard regularly.

• Value independency and self-sufficiency 

• Simply want your boat to be more comfortable, clean, and self-contained.

Even modest 60-80L/h systems change everything for smaller vessels — a sweet spot for couples, liveaboards, and extended cruising families.

​

12. The New Definition of Cruising

Classic cruising was about rationing, planning, and surviving scarcity. Modern cruising — supported by technology like desalination — is about sustaining comfort, safety, and independence.

Owning a water maker doesn’t make you less self-reliant; it makes you more adaptable, more self sufficient. You’re less dependent on external systems and better equipped for remote cruising.

That’s the essence of today’s seamanship — mastery through capability.

​

13. The Long View — A Water Maker as an Investment

A well-chosen desalination system adds tangible and resale value to your boat. For serious cruisers, it’s no longer an exotic upgrade — it’s a mark of readiness.

Buyers shopping for bluewater yachts look for a proven, serviced water maker almost as much as solar or autopilot. It signals that the vessel is prepared for extended, self-reliant life.

Over years of ownership, the time and convenience saved easily offset the initial cost. The intangible value — freedom, comfort, and independence — compounds with every trip.

​

14. Life Without Limits

At its core, a water maker represents a subtle but powerful change: from surviving at sea to thriving at sea.

It means you can take long showers. You can wash dishes properly. You can stay anchored. You can drink cold water from your own supply, knowing exactly where it came from.

It means the ocean is no longer something to fear for its salt — it’s your source of life.

That’s the real promise of desalination: it turns the sea itself into your resource, extending your world and simplifying your life.

​

Final Word

When you install a water maker, you’re not just adding a piece of equipment — you’re choosing a new rhythm of life.

You’ll stop planning around scarcity. You’ll start exploring without limits. You’ll turn your boat into a genuine self-contained home — one that takes care of you wherever you go.

At Water Makers Australia, we see it every week: the joy in customers who send back photos of clear product water, and smiling crews. It’s more than equipment. It’s freedom in liquid form.
