Would help. My boat more of less faces Southwest. The hill to the east blocks the sun until about 11 am. I can paint the southeast side before the sun hits, then move staging to the west side. It will be mid afternoon before the sun hits that side.In one of Jamestown's videos they suggest having the yard putting the boat in North-South orientation, that way in the morning one side is in the shade, then later that afternoon the other side is.
You can't paint in the sun and if it catches you, you're screwed! A breezy dry day is tough too even if overcast.
