Yeah I already recommended he try Fluid Foils, but as D-Surfin answered he is looking for something very, very specific. Not sure I will accomplish it but has got the grey matter ticking over.

True about kevlar Nick but it shouldn’t let go like straight glass and carbon can. Some of these things can be about the mix i.e. not all one cloth

Admit, also true but the residual effects of salt or alkaline solutions(?) on aluminium aren’t special. Got aluminium windows or screens on Casa Del Carroll, and have they ever been even immersed in salt water? I rest my case
I can understand perhaps a need and advantage in tow surfing but for your everyday ride? Cost of production I would have thought would be pretty high.
And I’ll tell ya something else, in my sailing days we had a centreboard blade of aluminium. Did not look too special even though it was rinsed.
