Hobie Float Cat 75 Pontoon

Since Hobie Cat decided to no longer make the Hobie Float Cats. (Which is sad) I was wondering where I could find a spare pontoon. The no longer have any at Hobie and refuse to make any more. I either have to find someone with a spare one or part out my Hobie Float Cat 75. I would prefer to buy a pontoon. Also, is there a way to repair the pontoons? Mine was drug over too many rocks over the years and I wore a large hole in the bottom tip. If someone can either tell me how to repair it or if they have a spare pontoon they would like to sell I am interested.
