I have a 1996 440 Express and she has listed to starboard since I have owned her (6 years). It has only been a minor annoyance but my winter project is to fix it. Today I discovered a bulkhead on the starboard side that is totally enclosed. It is about 10 feet long and would hold enough water to cause the list. does anyone know why this is enclosed? is there something in there? I am thinking of drilling a hole but do not want to drill unless I know safe to do so
