I agree that quality control could really benefit from a "pep talk". My red/green nav lights do not work and one LED does not work, also had 2 cushions with tears from the factory. These are all fixable as are most of yours.
As for the vinyl, I think your dealer may have missed the boat on that one. When I took delivery, my dealer went over everything and talked a lot about the vinyl. He warned that new clothes, vest, boardshorts, towels and other materials should never be allowed on the boat until they are washed a few times. He also warned about screen printing on the back of shirts and girls shorts/sweats, that they may stick and leave a permanent logo on the vinyl. He mentioned girls lotions and body sprays, as well as glitter, should be kept off the boat. We are buying a few white bath towels to keep on the boat and will not allow guests/riders to bring towels with them.
good luck with it all... fix the items to get the boat functional and go enjoy it for the summer, then worry about the rest of it when its too cold to ride
