Again, this may be true, but it might not be appropriate for all
systems. Adding a thru-hull and more components probably isn't worth a
few Amp-hours savings.


It's more than that... water cooling may save a lot o' bucks by using a
smaller unit. And it's more desirable in the tropics, where the ambient
air temp is higher. As air temp gets above the 80s, trying to air cool a
refrig'n condenser gets to be a losing proposition.

Another alternative is the keel cooler. At least two companies now are
making thru-hulls chambered & fitted for refrigeration keel cooling, so
you don't have to drill any more holes in your hull.

Some may be interested in my current project, 98% complete at this
point: installing a freezer built into our dinette seat. After a LOT of
research and spreadsheeting all the numbers, I decided on a Waeco
(Adler-Barbour) CU-84 (based on the Danfoss BD-35) air cooled
refrigeration unit, with an exhaust to the outside. The box is insulated
on 5 sides with R-28 vacuum panels. I am currently finishing the lids, a
relatively demanding bit of fiberglassing that I don't recommend.
