Supra offers skins for up to 7 years only so your boat would not qualify anymore for factory replacement.

Best bet is to find a local boat upholstery shop with great reviews and have them do it for you. At 14 years old, the foam may need replacing as well which ups the cost significantly.

One of the local to me shops has books and books with a wide variety of vinyls so finding something close to original is a possibility or you go with a newer style all your own.
