Cabin siding material search

I'm looking for a siding material, suitable for covering houseboat exterior walls.
I want it in sheet form.Please, no 4X8 panels or strips or other house type products.
It should come in rolls, have @ least a 96" width X ??? length & be applied by adhesive onto a solid plywood subwall. "seamless". It needs to have a finished surface in a light color.
Does it exist?
Thanks for any links or leads.

 

Google Kydex

 

Thanks. I'm looking for the "seamless " modern look found on new houseboats. How (what) do they cover those cabins?

 

How about urethane foam boards laminated with light biax S-glass. Light, cheap and easy.

 

Interesting product, have you used it yourself?

 

I have seen advertisements that offered a hull construction based on Kydex, but my own experience has been on commercial restaurant kitchens walls.
You have seen it too--- that white or beige bumpy plastic in rest rooms, etc..
Some stuff, sold by Home Depot, for example, is not Kydex but fiberglass, which is cheaper. Kydex is amazingly tough material. You might contact the company and ask about UV characteristics. In any case, painted, it would be very long-lived.
