can this be repaired? is there a glue for this, or does this have to be taken to upholsterer? when towing at 65 mph, the vinyl will raise about 8- inches the boat is 9 yrs old ,the vinyl has no rips or tears always stored inside. any ideas?
Sounds like either the foam has deteriorated and crumbled a bit (got smaller overall) and/or the vinyl has stretched. Time takes its toll. Head for a canvas and upholstery shop...or, depending upon the make, contact the builder. Some top boatbuilders keep patterns in stock to service existing boats in the field fleet. Might be an option, but you'll have to call to check.
