We have been living out of a cooler that we kept in our cockpit since we moved aboard on July 1st, 2013. It has felt like camping. While I do love camping, living out of a cooler was not fun for very long. We had to buy ice for the first 8 months, and for the last 2 months we have been fortunate enough to have been lent an ice maker by our friends Bill and Summer so we didn’t have to buy bags of ice daily.
For 10 months we were living out of a cooler with very limited food choices and lots of things going bad from getting too warm, molding, getting saturated in nasty cooler scum water, and getting smashed. We never imagined that the project would take so long, but between having to go to work, not being able to find what we need on island, and trying to figure out exactly how we wanted to tackle this major project, more time went by than expected. In retrospect it would have been a good idea to have bought a small dorm refrigerator from Home Depot to use until the project was complete, since we spent at least that much money on ice. Moral of the story, many boat projects will take ten times longer than you plan!
Why did we want to take on such a project, you may ask? Well, not only did the old refrigeration system look nasty, it didn’t work at all. Everything was the original system, from 1985. The compressor was basically a big block of rust, the insulation and seals were not energy efficient, and the cold plate system needed to run off of the engine, which we didn’t want to have to run multiple times per day to keep our food cold. Plus, minor detail, our engine does not work. We have decided to re-power and get a new engine soon. That’s our next major project.
The first step was gutting it all out and removing the old junk.

Next, the doors had to be removed.
The boxes were very uneven, so taking exact measurements was a big challenge. There is nothing square or flush about these boxes at all. Skeeter took as accurate measurements as he could, and using trial and error managed to cut the foam insulation to size. He glued the foam into place with construction adhesive. Then he filled in all remaining gaps and cracks with Great Stuff expanding foam. Next he measured and cut the FRP panels and glued them onto the foam. He filled in all of the cracks and corners with Bondo fiberglass filler. Toxic stuff when you are in an enclosed space and your head is in the box. Skeeter spent a lot of time upside down inside of the box. We aired out the boat as much as we could and took our cat Momo outside to avoid the toxic fumes. After all of that dried, Skeeter smoothed everything out by sanding, sanding, sanding.
Next step, he cut holes for the spill over fan between the freezer and refrigerator boxes. Then he cut a hole for the refrigeration lines and wiring.
After more sanding, it was time for more toxic fumes. Skeeter painted both boxes with brushable gel coat. The fumes were so bad that I smelled them from three boats down the dock!
Once that dried, we removed the oven and the mystery wires that were behind the oven. Those of you who bought old boats know all about mystery wires. The ones that come from and lead to nowhere. After that, 29 years of cooking scum and general filth were cleaned from behind the oven. My favorite cleaner is vinegar, since it is powerful, non-toxic, and does not harm the marine environment.
The compressor fit perfectly in the space behind the oven. Skeeter cut a hole in the bulkhead next to the compressor to draw cool air from the bilge.
The evaporator plate was ready to install. Skeeter and I stretched the copper tubing across the boat, careful to not kink it. He fed the tubing through the hole in the freezer box to the compressor, and then mounted the plate into the freezer box. Next, he installed the spill-over fan.
He installed the thermostats in both the freezer box and the refrigeration box. Finally, he wired everything together and VIOLA! He closed the doors, flipped the switch, and cold air was being made. We’ll see tomorrow how cold it gets. We are SOOOO excited!!!
