A previous thread mentioned Bronze portlights (absurdly heavy) and
also plastic ones (maybe not strong enough) but the glass/plastic
composite G10 is certainly strong enough. *Might be interesting to try.

Is anyone currently manufacturing them?

G10 is not as hard as Bronze but neither is the plastic normally used
for portlight frames. UV could be a problem but there must be UV
inhibitors in the other plastics too.
G10 is hard on tools but easy to work with. I have used it as backing
plates on several of my homemade boats.
