Why carry a watermaker

Stop Rationing Water on Passage

Relying on marina fill-ups or jerry cans works — until it doesn't. A watermaker gives you real independence offshore, in any anchorage, on any ocean.

01

Unlimited Fresh Water

Produce 30–5,000+ litres per day directly from seawater. No more calculating how long your tanks will last before the next port.

02

Low Power Draw

12V DC models run off your battery bank. Use solar panels or the engine alternator — no generator needed underway.

03

Compact and Modular

Designed for tight bilge and locker spaces. Modular builds mean straightforward installation and easy maintenance at sea.

04

Easy to Maintain

Clear manuals, standard parts, and worldwide membrane availability keep you sailing without waiting for hard-to-find spares.

How it works

Seawater In. Drinking Water Out.

Reverse osmosis is proven technology used by navies, expedition teams, and everyday cruisers worldwide.

🌊

Seawater Intake

Raw seawater is drawn through your hull fitting and sediment pre-filter screen.

🔬

Pre-Filtration

Particles are removed to protect the RO membrane from fouling and premature wear.

⚙️

High-Pressure Pump

Water is forced at high pressure through the semi-permeable RO membrane.

💧

Fresh Water Out

Up to 99% of salt removed. Clean, potable water flows directly into your tank.

Who this is for

Built for Sailors Who Go Offshore

Weekend coastal hops to multi-year circumnavigations — there's a system sized for your voyage.

Bluewater sailors

Ocean Crossings

Our compact 12V IMD systems keep you self-sufficient from departure to landfall on any ocean crossing.

Motor yacht owners

Higher Daily Demand

Need 200–5,000 L/day for showers, galley, and guests? The VR and IVS series deliver reliably.

Liveaboards

Full-Time Living

Water is a daily need at anchor. A watermaker pays for itself quickly versus marina fill-up fees.

Solar cruisers

Zero Diesel

Pair our solar IVS system with your PV array and make fresh water without running the engine.

Common questions

What Boat Owners Ask Us

Q

How much power does a marine watermaker use?

Our 12V IMD compact models draw around 7–14 amps — suitable for most cruising boats with solar or alternator charging. Larger systems run on 220V AC. We recommend the right option for your setup when you enquire.

Q

Can I install it myself?

Many experienced boat owners install our modular IMD units themselves. Full installation guides and technical drawings are included. For larger skid-mounted systems, we recommend a qualified marine electrician.

Q

How long does the membrane last?

With proper flushing and storage, SWRO membranes typically last 3–5 years. We use industry-standard sizes so replacements are available worldwide — including in remote cruising destinations.

Q

What water quality does it produce?

Our systems remove up to 99% of salt and impurities, producing clean drinking water that meets WHO standards. An optional post-filter adds minerals back for improved taste.

Q

Do you ship internationally?

Yes — we ship to 100+ countries. We can advise on shipping options to your port or marina, and include a freight quote alongside your watermaker quote.
