replacing windows

[ikrieger]

Any suggestions, tips or leads about DIY window projects would be greatly appreciated!

I was thinking of replacing the windows as described in the link below. What do you think?

I was going to buy either tinted plexiglass, acrylic, or polycarbonate. (Which one is better and scratch resistant?) Then cut it out router the edges, use 3M AHB tape with caulk around the edge to attach the window to the boat, no screws. What do you think? I like the idea of no screws because that means no visible hardwear, no holes in deck, less chance for leaks, no cracking of plexiglass from over tightening of screws. I'm worried that the tape is too weak to last long, or too strong and i won't be able to get them off if there is a leak. Feedback appreciated!

You really want to have the deadports through-bolted.

Personally, I would use Polycarbonate (lexan), preferably with UV and scratch resistant coatings. The holes in the lexan should be drilled slightly oversized and the screws should have washer or some other way of spreading the load on the outside, as well as fender washers on the inside.

Butyl rubber tape or neoprene gaskets are probably the way to go to seal the deadports against the hull. I'm not a big fan of silicone sealants on boats, since they tend to leave residue behind, making future repairs much more difficult.
