Ice Cream on a Boat!

While we work closer to the day of cutting the dock lines and cruising off to our dream, we are slowly but surely checking off our boat projects.  Most of us who have boats always have a project, and always will.  Our Catalina 380 has a decent size refrigerator, but a tiny freezer unit.  We have a large icebox we used to store "stuff". (All the stuff you thought you would use on the boat when you made the down size to the boat, but never did.   The stuff which was given away or placed on the if you want it take it table at the marina.
The project is an Engel ice boxy conversion kit..  The kit says it will bring down a 50 quart area down below zero.  The ice box was a little larger than 50 quarts, so with some modifications, we have a pretty decent size freezer for a boat.  The unit is super simple to install and runs on 110 or 12 volt and detects which power it has.  Initial power up pulls about 5 amps but drops down to about 3 amps wyhen on DC.  With some insulation and fiberglass work on the lid, freezer temperature while empty got down to minus 7 degrees. Have to say one of the easiest projects I have done on the boat.  We did make a run to the grocery store got a large roast, bag of chicken breast, frozen veggies, couple bags of ice we saved from the ice maker and it has frozen everything hard.
  

Installing the L shaped cold plate.  This process only took about 15 minutes, a couple of choice adult words because I keep dropping the tiny screws.

The cold plate is installed.  The next step was to drill a 2.5 inch mouse hole to run the copper tubing and thermostat wire to the compressor.  I used expandable foam to seal the mouse hole.  The copper tubing is precharged with freon.  Care has to be taken not to kink the tubing while running it to the compressor.  The instructions actually provide some really good tips on bending the tubing.  Any mistakes will only delay and add cost to the project.   

  

Carefully pulling everything through the mouse hole to the compressor.  This took the longest amount of time.

 
This is the salon settee where I placed the compressor.  The instructions suggested an area with good ventilation.  I added a large vent to the front of the settee, drilled two 3 inch holes through the back of the sink cabinet.  I then placed another large vent on the door of the sink cabinet.  This allows for adequate crossflow ventilation.  

The compressor itself is small and quite when it runs.  The space under the settee provides ample air flow and room to run the copper tubing and wires.  The 12 volt supply is a dedicated line with a switch on the power panel.  The 110 is tied into the 110 V for the port side outlets.
