Has anyone found a good way to make or purchase one? Only needs to be 4" tall to deflect the wind over my head! Any Ideas or links to products or companies would be great!

that is an opaque piece of fiberglass or some other composite material. has no frame. go get a couple big cardboard boxes from appliance store dumpster and start cutting blanks to see what'll work. with that tight bend at the corners fabbing it in 3 pieces and attaching the 2 corners together may be better way to go than trying to do it in 1 piece. the corner pieces of windshield frame from the 80's boats may also work as they are hinges of a sort and can be turned to whatever angle works best. but on this rather pricey and very sleek modern looking boat they won't look right. the roughest part will be figuring out how to attach it to the boat without negatively affecting the value. try to find one you can look at, even if you hafta lie and tell him you are looking to buy one...
