Tartan 37 Water Maker Installation

When I heard one of our water maker clients was making a stop over in Morro Bay, of course we had to have some cockpit drinks with them and snap a few photos of their SeaMaker 30 water maker installation.  I have to admit that Lewis on SV Eleutheria did an installation job that puts some professional boat yard installations to shame.  The happy crew is on their way to Mexico and their great use of space on their 37ft boat allowed them to install a 30 gallon per hour water maker without giving up much storage space.  They will be powering their water maker using the trusty Honda UE2000i generator and at $900 with free shipping over the internet  for the Honda, I wouldn’t want to go cruising without one!

Here’s a shot of the beautiful cruise ready boat on a Morro Bay mooring ball.


Where do put the control panel?  How about making use of some wasted space behind the campanion way ladder?

The 5 and 20 micron prefilters and Valving and Cleaning assembly are both mounted on the starboard cockpit locker forward bulkhead.

The High Pressure pump and motor are mounted on a shelf in the starboard cockpit locker and you can see the RO Pressure Vessels mounted up high in the cockpit coaming.

A favorite mounting location of mine for the RO Pressure Vessels is tucked up in the cockpit coaming.  It’s typically wasted space so you don’t lose valuable storage space.  Notice how nicely Keith tabbed the fiberglass mounting feet of the pressure vessels right to the hull.  Nice and clean installation.

Water Maker Installation and a Dedicated Through Hull

A common question about water maker installations is if you need a dedicated through hull.







Water Maker Installation: 1997 Hunter 40.5

The bulk of the water maker is installed in a hanging locker.  High Pressure Pump, prefilters, and the valving and cleaning assembly.  To save space, the two 3-way valves were removed from the Activated Carbon filter and mounted remotely.  A nice easy idea.


Remote panel mounted outside the locker.  Most of our panels come with switches for the Hp and Boost pumps, so this panel is not standard.


Due to space limitations, the client could not use our standard 40″ (SW30-2540) RO Membrane, so we used a 21″ x 4″ Membrane to save space.  These SM30-4021 Membranes are more expensive and have flow limitations to consider but with  large enough Hp Pump they can be a good solution for a tight installation

Welcome to the Cruise RO Water Maker Blog

Greetings from the chart table of SV THIRD DAY, our Hudson Force 50 sailboat that serves as our family home and the central California sales and service center for Cruise RO Water and Power.  My floating office worked while we were cruising Mexico and since we love living aboard we have no plans to move ashore, besides that would be just too normal for us! My business partner Charlie Hammel builds and ships our water makers and power products out of our San Diego, California office but thanks to modern technology and GotoMyPC, I manage the sales and technical support and service remotely.


We receive so many questions by email, phone, Skype and in person during our boat show appearances about how water makers work, that I decided to use a Blog format as a way to share our knowledge and experience in a way that will hopefully demystify the “black magic mystery” of water makers.  Four years of cruising Mexico with our family of four, not only helped us gain some real world knowledge about the role of water makers on a cruising boat, but also helps us to bust some of the mystery and “Cruise Rumors” passed along by all the “dock experts”.


So if you have water maker question, please post them using the “Contact Us” blog feature and we will address your questions in a refreshingly upfront way.  If you want to know more about our line of high output water makers, just shoot me an email at Rich@CruiseROWater.com and I will be happy to send you a copy of our water maker manuals to review.
