My 14.2 is a late 80's model and in fair shape. I am not the first owner and even when I got it about 4 years ago the bottom was a bit soft in the rear starboard side. This year it is noticeably worse and the bottom even sits on the trailer crooked as the soft spot deflect upward where it sits on the trailer guide rails. I assume the structure inside has deteriorated. Has anyone experienced this problem? Can it be repaired or does this mean the hull is a goner?
