I have cracked the material in the sliding section of the companionway. It appears to be a sheet of opaque white plastic about 3/8" thick. Does anyone know the material? Any recommendations for replacement?

Rob,
Mine is Lexan, which I would not recommend if you are in hot/sunny climates. The sun beating in can fade upholstery and instrument LED displays.

Try Sintra it's an expanded plastic developed for the sign industry and usually found in 1/8" thickness, but available in much thicker sheets. It comes in white and black is strong, very easy to cut or drill, light weight, waterproof, and it floats.
Look for it from a sign company. They may have some in-stock that you can look at or even have as a sample. It will be rather expensive but what isn't when you're buying it for the boat?

I second that about the sun fading the upholstery, (even here in BC, with an average of 318 hours of sunlight per year), but I do like to have the light and vision outside. I have a 1/4" bronze plexiglas sliding hatch, and it's much nicer than a solid hatch when you're aboard. A cover over that and the companionway when you're not aboard will keep the sun out of the cabin and protect the hatch boards, too. For more light when we're aboard, we made hatch boards out of twin-wall polycarbonate (like corrugated Lexan), which is clear, virtually weightless, and indestructible, so we don't have to baby them like the varnished teak boards...

A friend of mine replaced his with an equal thickness of smoked Plexiglas and it looks fantastic.

Ours has smoked plexi. Very heavy and starting to show from scratches, which unlike wood can't be sanded and varnished out. Almost lost over the side this year and THEY DON"T FLOAT, but managed to catch. I DO like the extra light they allow in, but have to hang a curtain at night for privacy and to keep the sun out at 5:00 am in the summer. Also have the same smoked plexi in our forward hatch. Neither were original.

"starting to show from scratches, which unlike wood can't be sanded and varnished out." - Take them to a plexi store, ten minutes on the polishing wheel and they can make them look like new except for any deep gouges. Probably charge you all of ten bucks if it takes that long.

Sorry to take so long to reply...major house reno in progress and I can't find the computer most days, let alone get to it to turn it on. I got our twin-wall from a plastics supplier in town, they sell it as greenhouse glazing and window protector. I had mine left over from another project, thankfully, as it cost something like $180 for a 4X8 sheet of 1/4", and they didn't sell partial sheets. You may be luckier in your area. Since I made both new boards out of one 2'x2' piece, it's pretty cheap per square foot, in boatbuck terms, but the other "wasted" 28 square feet might be a problem, unless you have a lot of friends with the same desire, or another project on hand. Best idea I ever had for a rainy area (I notice you share the climatic tendencies...)
