Thinking Out of the Box
So rather than a rigid framed screen, Char sews one which includes a small chain around the outside to hold it against the boat and give it sufficient weight to stay closed, and dowels to support strategically at the top, bottom and maybe elsewhere.When unwanted, it is easily rolled up and stowed.The screen then ties to the ss grab rail by two strings. It works for us.If you need a picture and dimensions, let me know.Jim
