Rumor has it that Duckworks has patterns and makes them. Idasailor used to, but stopped making windows. They DO make great aftermarket rudders. Kick up. Greatly improved windward performance. Sent from my iPhone

David, 1/4 or UV stabilized acrylic. You can cut w a fine bandsaw and sand to finish or a router w caution that way you can get the bevel (or radius) at the same time. avoid reciprocating tools as they lead to cracks. air cutting discs can work but if leaned on and tool rpm slows lends to jumping around and cracks. beveled holes for screws lends to cracking. pan heads are better if you can stand the way they look. the plastic expands and contracts more then the fiberglass so at issue is the sealant, must be flexible and yet hold to both the plastic and gelcoat surface. Some sealants have solvents that slowly degrade the acrylic, I don't remember but do the homework. My new boat has a 15 house on it and I took the old windows and the new material to a cabinet shop to cut out. Likely to be someone out there with more details.

I reminded myself the windows of our 1986 Montgomery 15 are cracked at some of the screws, could be bedded and sealed better, and are pretty scratched up. I think there has been discussion about replacing windows, maybe applicable to Montgomery 15's but I can't find it on the photo site and am having trouble downloading the entire history of this group to search, so I'm going to be lazy and ask here. I assume I'd need to fabricate them, so, some questions: 1. What is the best material, type and thickness, for example?2. What is a good source for the material, including tinted gray?3. I hope I could duplicate the shape of the old windows with a pattern bit on a router but wonder if that would melt the material to much. Any suggestion how to cut them out, bandsaw and a file?4. It appears the windows are beveled on the inside of the edges and creating that bevel could create a melting problem like cutting the windows out. What is a good way to create this bevel?
Any experience and suggestions are welcome!
