Do you install watermakers on sailboats, powerboats, and long-range yachts?

Yes — we install reverse-osmosis marine watermakers on cruising sailboats, sportfishers, trawlers, and long-range yachts. Each system is sized for your freshwater needs and onboard power capacity.

Can you install or service a watermaker directly at my slip?

Yes. We install and service watermakers at your slip or dock anywhere from Marina del Rey to Newport Beach, or at our San Pedro shop. If the installation needs a new through-hull intake below the waterline, that part is done on a haul-out. A one-way trip fee by distance applies to each visit, from $30 in San Pedro to $110 in Newport Beach.

How much freshwater can a marine watermaker produce per hour?

It depends on the unit. Compact 12- or 24-volt watermakers make from a couple of gallons to about 25 gallons an hour; AC-powered units on larger yachts make 20 to 60 gallons an hour or more. We match the unit to your water use, tank size and the power you have on board.

Is a watermaker reliable for trips to Catalina or extended Pacific cruising?

Yes. Modern watermakers are dependable on Catalina runs, Baja trips and longer offshore passages when they are installed correctly and get regular fresh-water flushing and maintenance. Run them in clean open water, not in the harbor.

Can you integrate the watermaker with my existing plumbing and tank sensors?

Yes — we integrate the desalinator with your freshwater manifolds, tank sensors, pressure pumps, pre-filters, and electrical system, ensuring smooth operation.

How much power does a marine watermaker need?

Most systems run on 12V, 24V, or AC power, with energy draw depending on output. We evaluate your battery bank, alternator, generator, and inverter to choose the most efficient setup.

Do you provide full maintenance, membrane replacement, and troubleshooting?

Yes — we offer complete watermaker service, including membrane replacement, pickling, pump rebuilds, filter changes, leak checks, and performance tuning.

About this service

Stop Rationing Your Showers.

With a watermaker, you no longer have to head back to the dock just for water. Breeze Marine Boat Service LLC installs marine watermakers (desalinators) that turn seawater into drinking water right on your boat.

Transform Your Time on the Water

A watermaker changes how you use your boat: water no longer decides when a Catalina trip ends.

Independence & Comfort

Take long, hot showers. Wash down the salt spray after a crossing. Do laundry onboard. When you make your own water, you stop worrying about the tank level.

Fresh Water Made On Board

Reverse osmosis membranes remove about 99% of the salt. Run the watermaker in clean open water, not in the harbor, and follow the maker's guidance on filters and water testing.

Energy Efficient Options

We install modern systems (like Spectra or Schenker) designed to run quietly on 12V/24V DC power, often from batteries charged by solar panels, without needing a noisy generator.

Complex Plumbing Requires Expert Hands

A boat watermaker involves high-pressure pumps, delicate membranes, thru-hull fittings, and integration into your boat's fresh water plumbing. A new thru-hull intake below the waterline is fitted with the boat out of the water, during a haul-out.

Breeze Marine does a careful, professional marine watermaker installation. We use marine-grade hoses, double-clamp connections, and install proper pre-filters and sea strainers to protect your system in the harsh saltwater environment.

Does a watermaker replace your water tanks?

No. It refills your boat water tanks. Product water from the reverse osmosis membranes goes into your fresh water tanks, so, within what the unit can make, the tank level no longer decides when you head back to the dock. Showers are usually the biggest fresh water use on board, and with a watermaker sized for your crew, a long, hot boat shower at anchor no longer has to be rationed.

When you ask for a quote, tell us how many people shower on board, along with your boat size and the power available.

Marine Desalination Systems: FAQ

What is a marine desalination system?

A marine desalination system, also known as a watermaker or desalinator, is a device that removes salt and other minerals from seawater to produce fresh drinking water. It is most useful on boats that spend long periods at anchor or offshore.

How do I know which type of marine desalination system is right for my boat?

The right watermaker for your boat depends on its size, the power you can generate and how you use the boat. We look at your water use, tank size and power supply and recommend a unit that fits them.
