    I am thinking of making a simple single seated canoe by bending a single sheet of corrugated roofing plastic/frp sheet. What should the optimum size of the sheet and what will be the best way of sealing the joint at bow and stern? I think many people in this forum have experience on that,I will be happy if you share the experience or knowledge...

    That brings back memories of when I was a kid, we'd use corrugated galvanised roof sheeting, hammer it flat at the ends, slot a piece of timber in at the end, nail the iron to that, and seal it with tar than had oozed through the planking on the bridge over the creek. But be careful, don't want any accidents !

    What size sheets can you buy. The ones I am familiar with would be too small for a canoe. You would need several.

    It's feasible, but anything plastic is, as you have found out, hard to join.
    One approach would be to use wire to tie the ends together, and then use some sort of commercial "goop" ( Silastic, Silicone) to make it waterproof.
    The problem is that wire will cut through the plastic over time.
    A longer-lasting solution would be to screw the ends into wooden strips of timber, before "gooing" them.
    If you are getting the "plastic" free, then it might be a fun project, but if you are paying commercial rates for it, its a much harder and more expensive solution than a common "fabric on frame" canoe.
