Well, no need for me to add photos of the ones we used to do, as this photo was the first set we did, on n/b Merryweather. Every boat after that, we were asked for them, and I have them in my own boat. We put vent into the sides of them after the first, to keep them fresher and cooler, just a simple routed out gap, with mesh over on the outer side of the box (my addition as I'm spider paranoid!) My experience is they keep things cooler, the space is well worth it. I wouldn't keep meat in it, but keep things like eggs, sauces that are supposed to be refrigerated, chocolate (drat, given away our stash place!) Onions, that kind of thing, oh, bottles/cans of beer and wine too. One boat had us put one near their stove, steel lined, for coal or wood! They can go anywhere. Handy in the galley area, or engine room if you have one.
