I just did it simple. Bought some nylon webbing at the hardware store and cut 2 dowels and stapled the cloth to the dowels with monel. Just roll it to store it. If I remember, I'll photo it this weekend.

Your solutions is intriguing! We love the idea of rolling it up for storage. What we can't picture is how the edges of the screen stay in place so that the bugs don't get in. How many dowels do you use?
We've also heard of people using spring rods, but also wonder about the edges in that case, too.
We'd love to see photos! Thanks again for the great idea!

I did this on my boat,
What I did was trace the hatch covers on too carboard, than then bought a piece of white sunbrella ( color choice is yours).
Once this was cut I stitched the edges and sewed in three batten pockets One on top one in the middle and one on the bottom. Once that was done I cut a panel out for the screen.
The thing with sunbrella is it breathes, as well as allows air to pass through, BUT most importantlly gives you privacy at night.
Simply unroll it and drop it in the slots and you are done.Then roll it up when you are done usung it.
I also am toying with the idea of making a new one that will span the complete hatch and companion way, with three snaps on the hatch edge, and one batten in the middle I would not even have to close the hatch at all.

I think I will wait till winter for that project, I need something to do while I am having a few cold ones and nothing to do

I purchased our boat from an owner who installed screens on every hatch with velcro. Works well and is easy to remove to open and close individual hatches. Our companionway hatch has the screen around the top and vertical openings. It has a zipper running down the middle from the bottom all the way to forward end of the companionway. It is easy to used, on all season. We can closed the hatch or use any or all the drop boards. The zipper works from the inside as well as the out side. At the end of the seasone the the screens are rolled up and stored.

Hello
I used batten at three locations just like our hatches. The screen is sewn into the sunbrella. When yo dop it into place it slides into the track for our hatch boards. Presto no DAMN BUGS. I am racing this weekend I will send you a couple of photos. The best part is it is cheap to make Battens were the most expensive thing. If you have a heavy duty swing machine you can do the stiching. I did not so I used a recoving place to do the stitching cost 15 bucks and I bought him a six pack for good measure (note after he was done stiching)

Not trying to hijack the thread.

Amazing what you can get done with some beer. I had 3/4 acres landscaped with a bobcat by giving a guy some beer. Cost me less than 10 bucks and saved me hours of work!
