Ha - well, Avon were bought out by Zodiac, who then stopped making the Avon branded small yatchsmen inflatables a few years ago (RedStart, RedCrest, Rover etc). The only Avon's made now are the huge Rib type tenders for super yachts.
So, now you are stuck with the likes of Zodiac's 'cadet' range etc, which is in PVC, not hypalon fabric.
I know all this because I spent a long time trying to figure out why the hell I could not buy new Avon's in NZ, or even order them overseas.
Finally I found a lightly used Avon RedCrest on T/Me for auction - I won the auction, but boy did I pay for it
