E38-200 - Solarmaax 10 Water Maker Installation - Ultra Compact & Very Quiet

Good day friends!

We recently completed the installation of our new Solarmaax 10 water maker from Electromaax. I'm writing this post just offshore of Moonstone Cove at the White's Complex at Catalina Island California. This is our sixth night here and I am so happy to report that the system has performed unbelievably well. The water is clear and the water temp is currently 56F. We are finding that the system consistently produces 8.5 to 9 gallons of water while consuming less than 110 watts of power. We have a relatively small water tank as we removed the thirty-five gallon tank under the port settee ahead of the sink for our 900ah LifePO4 battery bank and now only use the twenty-five gallon tank in the lazarette. We use a lot of water each day! I have restless leg syndrome. The best therapy short of walking or swimming is a shower. We use to have to take the dingy to Avalon which is about 3.5 mile or 15-20 minute dinghy ride daily to fill (3) 5g jugs to top off the tank from that previous days use. We really had to watch our consumption to only use 15g per day. Now, we have limitless water. We are finding that its easiest for us to simply turn on the device when we take showers to replenish what we're using while keeping the tank topped off. Same goes for washing the boat. I simply turn the device on and let it run. With so little power used and its nearly silent operation with the lazarette closed it just does its thing in the background. When we notice water coming from the tank vent we shut it down. We have 1200 watts of solar on the boat normally and then when at anchor we deploy our solar boom shade which each side has an additional 500 watts of solar. In that mode we have 1900 watts deployed. Needless to say, we have enough power to run the heater at night and the electric hot water heater in this mode. If we experience a cloudier day, we can fire up the Westerbeke which we have an Electromaax 250 amp alternator connected to which only burns around .6gph at 1600 rpms putting out between 160 and 180 amps of power at that range. In short order, we can top off the batteries if need be with the bonus of hot water. We installed a dedicated Victron smart shunt for the water maker to make it easy to track usage.

Astral, our 1989 Ericson 380-200 is the perfect cruising boat for my wife, cat, and I. The boat is a smaller than many other 38-footers, but with economical access to smaller more efficient systems, we have found the boat has more than enough room for all of the systems we need and assuming we do the work ourselves, quite economical to refit with modern systems. And oh my does she sail well!

John Stevens and his team at Electromaax have helped us with our system design and provided us with numerous components and stellar support. Peter Kennedy at PKYS Inc. also offered a ton of guidance for our ships electrical system, provided us with quite an array of Victron gear, and helped make sure we have a safe and ABYC compliant installation.

Wow, great looking installation! Thanks for sharing the pics, it’s got me thinking of space use in a different way.

Question, what locker is in photo with the piston arm on the right hand side. It’s the only spot I don’t recognize.

Thank you very much!

We refit the port side settee to accommodate the bulk of the new electrical system and make room for our tools, sewing machine, etc. We still need to move the refrigeration compressor so that area is more open for storage.

This was the first time Luisa and I had ever done anything quite like this. Its been a ton of work and we've loved every minute despite some colorful language during the process. Hahah

Here are some before, during, and today shots.

Thanks again for the kind words and please have a wonderful day!

We are just wrapping up modifications to the starboard settee as well. We added 6" of height just as we did on the port side.

We completed the locker with the installation of a 12K BTU Mabru 12VDC heat pump and over the holiday we completed sewing and installing the full boat shade. The side curtains roll-up onto the lower life lines. The bow backbone folds up and stores below. The boom shade rolls up onto the boom with its curtains also stowing on their respective lower lifelines. The (10) Renogy 100 watt flexible solar panels seen on the boom shade stow in a custom bag in between the solar brow on the dodger and the dodger itself in the gap. They are (4) heavy duty straps to contain the storage bag. Its been a ton of fun and we've learned a lot. We plan to leave the shade up for the next moth or so that we can find and address any issues that arise from the Winter weather systems. We had a couple of small issues develop in testing the boom shade last winter that were addressed during the work over the holidays.

Happy New Year Mr. Williams!

It's an honor an a privilege sir! Luisa and I have been following you and your adventures for years! Thank you much for sharing so much of your wisdom with us!

Table:

No sir! We do not have a "traditional" saloon table. To be honest, Luisa and I are far from traditional when it comes to meals and cooking. With this said, after living aboard for three years and rarely eating at the table, it was easy for us to remove it. We did install a nifty little rv-table we see from time in time in YouTube videos. I have not reinstalled the one we have on the starboard settee yet, but will this or next weekend and will share photos. Below are images from Amazon of the exact item we bought. We plan to install one more with additional brackets in other locations in the boat.

Amazon Link

They come with a nice backing plate and are very sturdy. What is most interesting is the fact that you can remove the table and or arm leaving only the bracket. They can be purchased without a table top and mounting brackets can also be bought separately so one table and arm can be used in other locations. I actually plan to mount two brackets in the cockpit to create a mount for working on the Suzuki outboard. Very versatile part.

Shade:

The shade and heat pump were specifically installed for our upcoming adventure to the Sea of Cortez. We are planning to head down that way in January of 2026 spending at least a couple of seasons before cruising further south. We've seen so many suffer with inadequate shade. We do not want to fall into that category!

We completed the reinstall of the table on the starboard side settee.

We went ahead and installed a second mount for an additional table in the future.
