I am trying to get Jacob's Dream ready for some short coastal cruising next spring.The norcold onversion it has been highly recommended and have started the shopping.I sail in a very hot humid climate with very mild winters.However, in the summer, humidity is very high also.Boat has central a/c unit which i love and am very pleased with, and i believe this will help.I would like to run the ice boystem on either 12v dc or 120v ac..ThanksCharles Creel
