Dehumidifiers do wonders for a houseboat. We sat one in the gally sink when we werent aboard. We left doors and interiof hatches open and always had a dry boat.

Note: its a PITA to have to replace all the rotted wood but when your done you will have a boat that is ready to go another 30 years. The Nautilines have a good layout and a lot of room, most have veedrives and big engines that are easy to work on and could take a lot of abuse. When your done you will have as good or better boat than you can buy today. You will know how to treat it and you will enjoy it for many years . Post pictures!!!
