The Island Packet 38 comes with a well insulated 14 cu. ft. icebox. Our boat had a Grunert 12 volt holding plate refrigeration system installed. We have run it almost non-stop for the past year and it has worked flawlessly. It uses R-12 refrigerant which is ozone depleting and no longer available in the US. We will pick some up in Mexico but if we ever have a major system leak it is history. It is important to plug the drain hold in an icebox conversion because the cold air will drain right into the bilge. Care must be taken to ensure that water doesn't collect.
Our water circulating pump on the refrigeration bit the dust and we found out that you need to clean the cooling coils with vinegar once a year to clean out the salt deposits. We had the pump repaired in Mexico but we also put in a new pump so our old pump is now a spare. We have put a blanket over the top of the icebox door and we are shopping for some closed cell insulation to lay on top of the stuff inside. These steps have cut down the power consumption of the fridge by about 25% gaining back about half of increase we saw as we entered warmer water and air temperatures.
The boat comes with a 3 burner propane stove with oven on gimbals. The propane is stored in a locker on deck with a drain out the side. The locker accommodates a pair of 10 lb. tanks. We went with steel tanks because of the reduced cost and we will keep them coated with rust inhibitor. One tank seems to last a little over 3 months.
We put down canned meat and cheese and things like that but so far in Mexico provisioning has not been a problem. Even in San Bartolome in Turtle Bay there was a well stocked grocery store and we had heard that their road was out since the hurricane a month before. As we are planning to go on to the South Pacific we don't regret our cargo but if we were just coming to Mexico we would not need so much food. Boat parts are another matter.
We will provide more information on provisioning and accessories after we get more experience.
