John, what color Plexi are you using? I am trying to replace the windows
on my boat and I'm having a time getting the correct color. Are you
using Translucent Acrylic black?
What color is normally used? I just bought some Gray smoked Polycarb and
the color is way off. Special order and they won't take it back. They
called it 7135 Lexan.

I want to add a fixed window on the fore part of the cabin, so I can see
through the cabin whilst seated at the helm.

A tall cushion might be as good, but being able to look forward from below
counts, too. Maybe a bent plexiglas cowling trapped under the partly
opened fore hatch?

The forward cabin bulkhead is curved in one direction, radially around the
mast, so to speak, but not so much vertically. I have in mind to cut a
hole, then flex a sheet of plexiglas, whatever, bolting it through. I
wonder if 5200 can be trusted to never need replacing, is good enough, too
good, or if there are alternatives I have not imagined?

Hello
Just finished replacing six 25 year old acrylic Fuller Brush 7"x15"
port lights. The all leaked and were cracked. Why? the house has a
curve to it. So when port started to leak PO cinched them down and they
cracked. Acrylic can not take much of a curve.

Replaced with 3/8" polycarb/Lexan through bolted with 316L ss 1/4"
machine screws. Used a 1/8" 316 trim ring inside and out as a "washer."
Absolutely bullet proof. Lexan bends without cracking.

If your house has a curve do NOT use acrylics/Plexiglas. It will crack,
if not when drilling it, later from stress from the curve of the
house.

When you go the lexan route can not use 5200 like sealants. I used a
Dow Corning product; 791 I think.

Bob
