I thought Hypalon was a recent development and that the older

back then?


I've got a '76 Zodiac made of Hypalon. It was used a lot in the earlier
days on quality inflatables (and even some cheapies). Not used that much
anymore. The new Zodiacs are some form of PVC.

Hypalon can be a bear to glue. Be sure to get the right adhesive (usually
a 2 part mix) and follow instructions carefully. If you're gluing two
different parts of the boat, find out if they are the same material
first. The glues are different (for instance my Zodiac has a vinyl
bottom, vinyl to Hypalon has a special glue). I find that I need
to abrade the material more than I think in order to get a good bond.
