7m rotationally molded jet boat

Stumbled upon this today. Has anyone else seen this? Cant seem to find a weight of the boat? Looks like a pretty sweet idea. Would imagine initial tooling costs wouldn't be cheap? I wonder how this technology could be used in other marine settings. In surf lifesaving in NZ and AUS where we race surf-boats and canoes which frequently colide in surf this material could be great. I know stiffness translates to speed so I wonder if this could compete with a identical craft built of fibreglass?

Compete in what respect ? The claims that the flexibility translates into a less harsh ride is one I would doubt, but I haven't been in or near one, so could not be too categorical. Conventional wisdom is sponginess gives a worse ride, not a better one.

 

I meant if a plastic surf-canoe or surf boat could compete with identical glass boats in competition so i guess speed. But I'm guessing a plastic boat would probably be a fair bit heavier so slower.

 

A cursory look at specs suggests they are not lightweights, this company is well established in making such craft:
