Depends on angle of sun
Jim, it covers a large portion of the cockpit whenever the sun is forward. Admittedly it doesn't cover much in a following sun (whether rising or setting) but that is when the sun is less intense. The bimini is wide as well as long so it puts out a lot of shade area. If I coupled it with an aft bimini (like those sold at this website) it would really cover a lot.With the mainsheet in the middle, you have to choose forward, aft, or double!
