Pulled the ole' gal out after maybe five weeks. Had noticed before on the port bow, about one foot or so back a couple of "impact" marks. Thought it was strange as there were no marks on the exterior of the boat. So now I noticed a whole bunch more appearing - like twenty or so. Geez! They really look like somone had popped a ballpeen hammer on the inside with a good whack as the center of the crack seems to come from inside out. This is the only area they are appearing in. Thought maybe a shabby repair job. Called the PO and never repaired, he was original owner. Have known him and the boat for awhile so no reason to B.S. me on that one. Nothing on the interior would have the ability to come in contact with the hull. This one has me stumped. Guess I'm not so worried on how to repair but as to what might of caused this problem?
