I have a fridge under the galley top to the centerline of the sink. It’s a12v college dorm style fridge and only size that would fit the available space when they constructed the boat apparently. The freezer in it is tinyWhat do you have now, cooler, fridge, etc.? If you have a cooler, installing a box evaporator inside the cooler will give you both a freezer and fridge.
Must defer to other 36 owners for a solution. Our boat has a built in freezer/fridge with AB systems. If it were a built in cooler, it would provide some options, but what you have is limited, short of fabricating a built in system.freezer recommendations and where you located it in the boat.
