On our boat we went with a board uphaul line that goes from the handle of the board, through a block lashed on the port shroud, then to a purchase under the tramp. Uphaul line comes out from under the tramp about halfway between the starboard shroud and the aft beam. Our system needs some work, it was a kinda rough solution before NAs. We didn't want to drill through our boards, so we went with the line to the handle.
