Jeff, regarding your Breeze Booster, how does it attach to the hatch? I see that the hoop around the front of the hood is pulled down by tensioning lines tied to a stick which inserted into the hatch, sticking to either side of the hatch. But the back, does it just sit there on the deck? I assume the deck lip of the scoop is weighted? Does it ever blow up? I suppose if it's strong enough wind to blow the back of the scoop off the deck, it's strong enough wind to not need the scoop… Also, it appears that you need to have the Breeze Booster screen accessory, because the stick and tensioning strings obviate any screen which may fit into the hatch itself. I have a Waterline Designs hatch screen which is tensioned up to the hatch rim from below on a cord with a suction cup stuck to the hatch.
I like the idea of the Breeze Booster, because it is self supporting, and doesn't require a halyard or line tied off like other wind scoops or the Sailrite "awning" design.
