Would be interesting to have an alternative supplier for curved windscreens, have found that the boat manufacturers have restricted their suppliers to only supplying them, then seem to be doubling up the price to the end user. Makes replacements vvvvery expensive!
assuming you want to replace with perspex, plexiglass whatever you call it, WHY do they have to fit them in their oven???
Isn't it a matter of just cutting in shape and then curve fit in situ, or is it so curvy that has to be heated and curved?
