I have a Cascade 29 out here in Honolulu, Hawaii. I am thinking about taking out the propane stove and replacing it with a refrigerator. I am looking at a compact Avanti model for sale at $100. It measures less than two feet in any direction. I can bolt it to the plywood where it will rest. I have two questions: 1. Will it cool enough for a tropical climate? 2. Will it be able to withstand the jostling that it will get sailing rough Hawaiian waters?
