High Outpot Water Makers Model Differences

Our 20, 30, and 40 gallon per hour water makers all have the basic design and layout in common. Understanding the differences between the models can help you pick one right for your boat.


Water Maker RO Membranes

RO Membranes are the heart of your boat’s water maker, so the more you know and understand about them, the better you will be able to select the best water maker for you boat or take care of the water maker you already have aboard!


Merry Christmas from Cruise RO Water Makers

Winner of a "Major Award"

SV THIRD DAY all decked out in Morro Bay, CA

It’s hard to believe that this is our 7th Christmas aboard a boat!  The memories of spending Christmas on a beach with with our friends in Mexico certainly has to rank among our top memories of cruising Mexico.  This year with a Morro Bay, California 70-deg Christmas, it’s certainly nothing to complain about while sitting with the boat opened up in shorts and T-shirts.  But as a concession, we do have to run the diesel heater at night since our time in Mexico has made us all total wimps when it comes to tolerating the cold.

Where ever you are this Christmas season, the crew from Cruise RO Water and SV THIRD DAY wish you a Merry Christmas.

God Bless


The Importance of a High Output Water Maker Boost Pump

A common question I get by email is about the boost pump.  Do I need one?  What does it do?  Why is yours standard with the water maker and others offer it as an option? What if I mount everything below the water line, do I need one then?  The question are common enough that I thought a video addressing the issue would be useful.  So on a rainy December day while on the Morro Bay, CA mooring ball I pulled out my video camera and started talking about the topic.

Why Do Boat Owners Need Water Makers?

Water Makers

Boat owners need water makers because people on the boat need clean drinking water. Indeed, fresh water is not only good for drinking, but also for cooking and cleaning purposes.


Depending on the size of the boat, number of people aboard, and amount of time the boat will be out cruising on the water, away from land, a marine water maker can be an invaluable way to add drinking water to your water tanks at the flip of a switch.


Water makers cleverly use a process called “reverse osmosis” to make water. Water makers use high-pressure, pump-driven reverse osmosis systems to desalinate water, converting sea water and/or brackish water to ready-to-drink water fit for human consumption.


Humans on boats for extended periods of time couldn’t survive drinking sea water, which has too much salt in it to be of any good to the human body.


Water makers, therefore, are often essential systems used on yachts, sailboats and other vessels operating in brackish and/or sea water environments.


Cruise RO Water and Power understands the challenges of powering a large capacity water maker aboard a boat. That’s why Cruise RO came up with the smart idea of designing SeaMaker 20 and 30 gallon per hour water makers to operate on the power produced by the Honda EU2000i generator. Affordable for all, Cruise RO’s water makers can make 100-150 gallons of water using a single gallon of gas. And that means good stuff: daily showers for the crew (thankfully!), fresh water deck and gear wash-downs while at anchor, and, of course, plenty of clean water to drink.

If you are a cruiser, know a cruiser, like a cruiser or one day dream of cruising on a boat in the United States, then the topic of Anchoring Rights should be important to you.  Local city governments are passing more and more restrictive limits on prime anchorages and once gone, getting anchoring rights back is all but impossible.  So please take a moment to complete the Florida Anchoring Survey

Can I Run a Marine Water Maker in Fresh or Brackish Water?

Cruisers are not always floating in just sea water.

Sometimes they are in fresh water lakes, rivers or brackish waters but they still want and need water.  If you understand the process and limitations, then you can run your water maker in sea water, fresh water or brackish water.
