Has anyone used srPET as a hull material?

It's from Denmark.

Does anyone know its cost as compared to fiberglass or epoxy over ply?

Made by Aptiform, if I'm not mistaken?

Strength/weight and stiffness/weight seem to be in about the same ballpark as more conventional FRP composites. It looks like the moulding procedure can be rather involved; the manufacturer suggests that it could be used for PWCs. That seems like it could be reasonable; the tooling costs for these can be spread out over thousands of hulls. Whether it would be economical for shorter runs of larger parts would be an interesting thing to study.

It is interesting, and I know they used it on Plastiki to support all the 2 liter bottles, so I was wondering how it would fare as a hull material in general. Yes, it's made by Aptiform.
