The "fridge" is hard to photograph because it is located in the port passageway between the galley and the aft stateroom. The photo above shows the refrigeration unit as viewed from the galley, looking aft.
The unit has both a "freezer" box and a "refrigeration" box. The boxes are made of stainless steel, have good shelving inside, and have approximately 3" - 4" of foam insulation. The cold plates can be charged from AC power, with the main engine, or with the generator.
The refrigeration unit works very well ... we consistently had the coldest beer around!
