After repeatedly finding water under my aft berth cushions I decided to track down the origin of the leak. As it turns out it is an overhead leak originating at the base of the Edson pedestal as well as the emergency tiller cover plate on to the ceiling of the berth and down behind the back wall. I fear that the fix could be a daunting job for someone like myself. Does anyone have any experience with the same problem? The boat is a Catalina 28.
