Thanks for the replies. My biggest problem with the "plastic," regardless of what type it is, is that storage is a problem. I dont use the curtains very often. I use the front curtain while running sometimes just to keep any spray off my face. I only use the side curtains in the cold weather. I think I've put the rear curtain up 6 times or so. So, all these curtains stay on- board, folded up and crammed into the small storage space. If I were to roll them up, I definately dont have room for them.
I was thinking that if i had two glass sheets that were connected in the center with some flexible fabric, I could store them more easily since they are flat. I was thinking of connecting them to the windshield and bimini with those little turn-button fasteners... not an actual snap.
I know this sounds like a pretty off-the-wall idea, and it probably is. I've never been acused of being normal.

I just hate to spend all that money on new curtains, then have them get scratched to pieces. I know all the new plastics are very clear... it's really just a storage/scratching issue. I actually bought a piece of Eisenglas to make a temporary front curtain to get me through the rest of the season earlier in the winter. It's already scratched by the way. One thing i notice about all the replies (and I'm not knocking here... more of a jealousy issue), is that all you guys are running 26'+ boats. There's not a whole lot of extra space on a 20'. Plus, I trailer, so if they need to be up due to weather, they come out of storage, go up, then go back into storage for the ride home. I'm trying to think of what will best suit my needs and not damage brand new material.
Again, thanks for the replies. It's got me thinking about different storage scenario's... but I haven't dropped the glass idea. :lol:
