I knew it was only a matter of time. Been working on multiple boat projects and actually documenting things with my digital camera. However, GOBI got me last night.
I have decided to take care of the icebox from two different angles. I have added a pump and momentary switch to mirror that used in the head for the shower sump. The original plan to use a T pipe (aka dishwasher connection) from the galley sink drain was a good one in theory but turned out not to work, the dishwasher T-pipe is 1 1/4", galley sink is 1 1/8". So I built a T from PVC and tied it into the drain hose just under the sink. The hose from the pump have a loop that is higher than the sink drain which I belive will help take care of any back flow. The second part is to add refrigeration to the icebox. Instead of a multi-$100 bill rig, I purchased a Kenmore dorm fridge for $50. This design does not have the compressor cooling grid and looks very similar to one of the marine retro-fit kits, obviously not 12v switchable though. The 110v only is not an issue for me as it will take care of things at the dock, and this icebox is extremely well insulated. If need be we can switch to block/bag ice for long periods on the water and jsut use the sump pump for the melt water. Unfortunately GOBI was helping so while removing the cold plate from the fridge last night I slit my thumb open, fortunatly i went parallel to the tendon, not accross it. So boat projects are on hold, typing is an adventure.
