Which watermaker suits your boat?
The right system depends less on the boat than on how much water your crew uses and what power you have to make it with. Each page below starts from a realistic daily figure for that kind of vessel and shortlists what fits.
How to pick a marine watermaker for your boat: daily litres, run time, and what each system costs your battery bank. Every model compared on Wh per litre.
Choosing a watermaker for a cruising yacht: realistic daily litres, run time, and the energy each system takes from your house bank. Compared on Wh per litre.
Watermakers for sailboats: why energy per litre decides it on a boat with no generator, which systems fit a house bank, and what each costs to run.
Catamarans have more solar, more space and usually more crew than a monohull of the same length. What that means for choosing a watermaker in Australia.
Motor yachts usually have a generator, which changes the calculation entirely: buy output per dollar rather than paying a premium for energy efficiency.
Living aboard means daily showers, laundry and dishes, not passage-making rations. What that does to watermaker sizing, and which systems keep up.
On a small boat, space and power are both short. The compact 12 V and portable watermakers that actually fit, compared on output and energy per litre.
Charter operation means full crew, guests who do not ration, and downtime that costs money. What that demands of a watermaker, and which systems suit.
Remote cruising means no dealer, no spares run and no shore power. How to choose a watermaker you can keep running a long way from help.
Deck washing, ice and crew water add up fast on a working boat. Watermaker options for fishing vessels, compared on output and running cost.
Making water on sunshine alone is achievable with the right system. Which watermakers fit a 400 W to 1 kW array, and exactly what each costs per day.
Portable 12 V desalination for coastal touring and remote camping, and the honest limits: seawater or brackish source, real power draw, and what it weighs.
