Morro Rock welcoming us with fog.

Before I dive into the project talk, I’d like to say that I ADORE MORRO BAY! To the point of it being on my list of places to return to in future landlife. My adoration is partly due to Morro Bay’s proximity to Paso Robles, Hope in Spades Ranch, and friends. Mostly, it’s just a great town. It’s small. Like the kind where you would eventually know almost everyone. It’s filled with character, sometimes making it feel old after decades in Vegas, yet also quaint. It’s close enough to SLO (San Luis Obispo) to get one to Costco and the “big stores.” Not so small as to not have any services or handy stores.

We arrived here in late September. Took a few days to decompress and catch up on sleep. For October and November, we’ve been in a slip in the heart of the embarcadero. Basically, at Anchor Memorial Park, between Giovanni’s Fish Market and House of JuJu.

It’s a short walk to pretty much everything. Even Albertson’s is only .6 miles up Harbor St. We are .1 mile away from what has become our go-to restaurant, Hofbrau Morro Bay–if you come here, do yourself a favor, get the French Dip and Clam Chowder. They also have tasty brewed iced tea.

Project 1: Refrigerator Swap for Tropics

MACH 5 came with a good-sized, top-opening fridge and a ridiculous shoe-box-sized “freezer.” I use quotes because it barely froze water to a solid enough state to be called ice. Barely. A pint of ice cream would turn into a Wendy’s Frosty, not even DQ Blizzard consistency.

The Dometic/Adler-Barbour unit was not original but also was not new. It cooled itself via air. So whatever the air temp in the boat was dictated how efficient the fridge could be. Meaning, cold-ass summer in San Fran = happy fridge; 90+ temps during a Stockton summer = not even keeping cold foods at a safe temp. It has prevented us from cooking at home and being away from civilization. Going south would only make it worse. This is a great setup if you sail on weekends or for short stints.

As liveaboards and cruisers, we needed better insulation, a bigger freezer, a freezer that freezes, and a water-cooled system. Our vendor-turned-friend, Alan from The Boat Guys in Alameda, recommended a SeaFrost system that is air-and-water cooled along with added insulation.

Mark spent hours on the phone and on video calls with Alan as Alan taught Mark how to do various parts of the installation that weren’t obvious. Mark has new tools and new skills!

Let’s take a pictorial journey of the process.

This is the original fridge box config along with the new cold plates. We are sizing things up to get started.
Mark got to practice boat yoga to install the compressor under the port settee (aka my seat) about 3ft from the fridge box.
Bending styrene plastic with a heat gun to wrap around foil-lined foam board for insulation.
Example of styrene being curved to cover the foam board. I think we spent a solid 3 days just making the insulation templates out of popsicle sticks, cutting 9 pieces to become walls, bending, and adhesive-ing.
We used a lot of sikaflex.
The new wall divides the fridge side from the freezer side. Clamped and cured overnight.
The new interior walls were affixed with sikaflex to the old walls. As they cured overnight, we stacked everything we could against it to form the shape–which is not straight.
The same new wall from above, after curing. Yes, we even made removable triangular insulation to cover that drain. We can’t block it completely because that is the only drain for defrosting.
The new two sides: fridge left and freezer right. Yes, that is a trekking pole on the left holding down a new wall to cure.
It’s alive! Look at the gorgeous frost on that cold plate!
Inkbirds are the temperature management things. Top freezer and bottom fridge. Essentially, they are switches that tell the compressor and fan to run.

The fridge project took 5 full days of work. Not including research, prep, or maintenance that we need to do. It worked great while we still had electricity. That’s the project we are doing today and has been for days or weeks. So it feels.
