Canoe Seats

[TOYOA]

I have a 16'+ Grumman aluminim canoe. I got it second hand and the seats(interwoven nylon straps) have dry rotted. I can't find similar material to replace it with. I have used plywood as an interim fix(with cushions) but I'm not found of this solution. I have had very limited luck surfing the web for info from retailers & such. Anyone with an idea or contact please let me know.

Thanks,
Neal
