I am about to rebuild the portlights on my E25, using the Catalinadirect.com gasket kit. The original glass is in good shape, but I have been thinking about going with acrylic.Clear polycarbonate (Lexan, Makrolon) and Acrylic (Lucite, Plexiglass, Perspex) are both good materials for boats, but have somewhat different properties. One isn't necessarily "better."
Polycarbonate is stronger, but scratches more easily than acrylic. Acrylic cracks easier.
Acrylic is shinier and clearer.
Polycarbonate yellows in sunlight, acrylic does not.
Acrylic is cheaper.
Both materials are stronger than glass and lighter. Polycarbonate is used for unbreakable sunglasses and is bulletproof in layers. Acrylic is what most fish tanks are made of.
I chose acrylic for hatches and portlights. You can stand on my 1/2" companionway sliding hatch and overhead opening hatches. No scratches in two years of hard use.
I think either is fine.
Is the gasket kit essential or can one simply bed the glass or acrylic in a bead of something like Dow795 Silicone?Can't beat glass, can you?
As I recall, others have said that gasket kits require specific thickness, which might be something to confirm early in the planning.
Yeah, what Christian said. My experience is the Catalina kit glazing vinyl is for 3/16" panes and the Ericson 26-2 ports I refurbished had 1/8" panes. Of course, if you (Blue Streak) are making new acrylic panes they can be any thickness you want within reason. Maybe get the sealing kit before you buy acrylic so you're sure to have compatible sizes.Can't beat glass, can you?

I think the gaskets work with the original glass, but we'll soon find out!Yeah, what Christian said.

Frank I had glass in my 27 which did not fit into either of the gaskets I ordered, so I gave up and bedded them in 795. That was in 2011 and no leaks so far that I know of (sold it to a friend and it’s moored nearby so I keep track of it). Same with my 30+. Nary a leak in 6 years.

I too contacted Hatchmasters and a couple other "full service" $$$ window places in the area. In the end I went to The Plastic Factory in Bridgeport. I gave them the old acrylic pane (I did the removal and install myself) and they cut perfect replacements for ~$40/pane. 2 yrs later I have no complaints. It goes without saying, start with one porthole and make sure it's do-able rather than replace all 8 in one goFWIW I recently went through this process and paid HatchMasters of Norwalk Connecticut to replace the lenses in my 4 Ericson trapezoid lights.
The guy at Hatchmasters is kind of a Pain in the Aft to work with, but the finished product seems to be good. $300 per window labor and materials, not cheap.
Here is their discussion:
Acrylic vs. Polycarbonate - HatchMasters
I spend inordinate amounts of time discussing the pros and cons of acrylic and polycarbonate. In so much as I would like to bring some clarity to this issue. Please consider the following: All major hatch, portlight, and window manufacturers use Acrylic in offshore / bluewater marine products...hatchmasters.com
When I replaced my four original crazed acrylic fixed portlights in 2016, I had the chance to select cast acrylic or tempered glass lenses in the new versions from the original vendor, Mark Plastics of Corona, CA. The lenses in these vinyl frame portlights are not replaceable. See the thread:I have a broken portlight on my E35. I notice 4 of my portlights are marked ”tempered” and two are not. The glass shop says the broken one I brought in is laminate. My question is, to replace with tempered or laminate? Glass shop can do either. Any input?
