Has anyone converted one of those camping 12V coolers (Amazon.com: Koolatron Voyager Thermoelectric Cooler - P-27: Kitchen & Dining) to their icebox?

These coolers use an inexpensive thermo electric transistor to cool, however they are terribly inefficient. They usually draw 4-6 amps per hour and only cool down 35F degrees below ambient. IMHO, a better and cheaper option would be to put extra insulation in your icebox and purchase block ice.

Thanks Jeff. Didn't think of the amp needed, and the wear and tear on the batteries. 90% of our sailing are day sails and would like to keep something cold on board between sails. Dockmates with comparable LOA (28'-30') have put in college dorm sized 120v fridges and just don't power it during day sails -- but they do get to arrive at the boat with nice cold drinks.

NoWet, you might want to consider adding a extra battery to the house bank and get a small inverter to power the 120 volt "college dorm" refers. These small refers are pretty efficient - if you keep the door closed, and don't draw too much power compared to thermo electric transistors. Using the inverter during sailing trips should not tax the battery bank very much.

Jeff.

blj...where'd the dog go?
Looks like the new box is longer than the space you put it in?

Uh...would acquiring a whole boat for nothing (except for gas from TN to Montgomery, AL & back) count?

Not at today's gas prices.
