I have a 1974 23' "pop-up" O'Day. I got it last summer and spent the rest of the year learning how to sail it. In Feb. of this year I took it out of the water to do some much needed repairs.As with anythig else this to turned out to be more than I had planned on. The good thing is that I only bought the boat for $150.00, So, any money that I put into her just makes her all that better. The problem that I'm facing right now is the "portholes" or "portlights" as some may call them. When I took the portholes out of their mountings they were so britle that they just started to break to pieces. This in it self was not a bad thing because the glass in them were all discolored and scratched,so I had planned to replace them anyways The Question that I have is, Where can I find the right portholes for my boat? Thanks so much.
