Use of Lexan

I just wanted to post a quick note about the use of Lexan. We replaced the large-area ports (windows?) on our Fantasia 35 back in the mid 80s, using half-inch Lexan. The material came from the bulletproof windows in a bank, but since it was surplus or reclaimed, I don't know any more details on the exact type. We used those windows, full-time liveaboard, for maybe another 5 years, and never saw a single stress crack or any crazing.

The boat has been up on the hard since '91, in the direct Florida sunshine, and I visited it last year. The windows are still solid, and I didn't see any evidence of cracking or crazing, and that's with 20+ years of weathered exposure. The Lexan has some patchy tan discoloration from the many stainless through-bolts rusting lightly, but I don't expect that would be hard to clean up.

Perhaps we were just lucky on the cracking thing, or perhaps it's the really heavy thickness we used. Lexan definitely does scratch easily, and that was the biggest downside to our use. After a few years they were good for letting light in, but not for seeing through very clearly. I'll probably try polishing them when I get back to working on the boat.

For what it's worth..

That why I mentioned the MR-10, it's superior to std lexan in both scartch & UV protection, I'm using it on our forward hatch and it's been there 2 yrs now

Sad, but true . We lived on her from '81 to '91, but since then she's been about 1200 miles away from me. I hope to either move down there and fix her up, or find someplace to store/work on her up here, but for the moment she's still sitting.
