Protective hatch without cover?

[Franklin]

Does something like this already exists? A hatch that doesn't degrade in the sun and also keeps UV rays and most heat out of the cabin without using a cover?If not, think it would be possible to make a hatch cover that lets light in but not UV rays? Maybe create some kind of UV protected flim that can be placed over the glass but tucked in and transparently glued to the top of the glass. Unlike applying the film to the inside of the glass, this would actually protect the glass as well as the interior of the boat and help keep temps down inside without blocking all the light and therefore the need to remove covers. If the film is simi-strong and glued tightly against the glass, it should mostly stay in good shape against normal uses. What do you think?

Why not put a thin sacrificial lexan cover

over the hatch. I am thinking of something like one sixteenth inch thick. It could be replaced easily and cheaply if it got scratched. You could sandwich another protective filter layer under it, too and change it to suit the season.How about something sandwiched like a picture you could change from time to time?

Look in the yellow pages or search the site for a local sales place. I got a 4X8 foot sheet for about $20 and cut it on a table saw or with tin snips. It is easy to work, cheap and comes in various colors. I am using some of the thicker white material to make a hard dodger top replacing canvas.
