If you haven't already, check out Steve Weinstein's reefer project on the Photo Forum. Geez I wish I had known about that slick thru-hull cooler when I bought my Adler-Barbour. I have always wanted to replace the thru-hull and gate valve to my galley drain. That would have been the perfect option. Lake Erie water(70 degrees max) would have made the condensor so much more efficient.I am surprised at how much better the H33 ice box is compared to my H37C. You have a large opening and easy access to all corners. If you have never seen the H37C box it has a small lid back in the corner. Then a large part of the box goes way aft into the starboard cockpit locker. There is another leaky lid in the locker so that you can reach in for a beer without going below. Not a bad idea but hugely inefficient, both in cooling and in access.At any rate a superb job Steve!
