I have considered getting a solar cover or blanket, as I've heard them called. I guess I'm little confused about how they actually install. Do they float on the water ?(what keeps them from blowing off?), or does it wrap over the sides, kinda like winter covers ? Also, how easy are they to put on and take off ? Some pictures of the cover/blanket on would be great, if anybody has any. BTW, I have an 18' AGP.

thanks
