Just purchaed a 1981 fish in very good condition When I got it home after a trailer trip of 160 plus miles I heard what sounded like something loose in the hull. . There is no inspection port..and given the boats age I surmise that a block came loose during the trip even through the boat was well cushoned with full bunk beds on the trailer... augmented by swimming pool noodles. Any major consequences if I use the boat in this condition?
