New shades from SailBoatOwners.com. Four of these took about 20 minutes to install and cost less than $200. They look very nice and are quite lightweight. I wouldn't call them durable, the kids can't swing from them, but I see no reason they would not last a very long time.

They are fastened at the top with small stainless screws (provided) about every four inches and at the bottom with small velcro patches. The velcro patches that came with the shades fastened with one screw in the center of the patch. I instead used small, round, stick-on velcro patches just to have a few less screw holes.

SailBoatOwners.com provides great service too. It took about four weeks from the time I ordered the shades until they arrived.

Highly recommended.
