my techneque
I flip it upside down with the bow forward and attach the spinacker line to the stern lines. I then tie her down with a line across the midsection of the dinghy (I have hand rails in the perfect place to tie too). After tieing her down as tight as possible, I pull on the spinacker halyard to make it even tighter. Dinghy doesn't move much at all and the stern board is off the deck.When I get around to actually get a spinacker I might run a seperate line for this. In the meantime, this works well for me.Note: When tieing her off, I use quick release knots...no need to get crazy in bolting her down. I've been in 30 knot winds with her there with no problems while sailing and 70 knot winds at the slip with no problems...well...except for that it scared the crap out of me (I was just waking up to go to work when it hit like a brick wall which caused a lot of stuff to fall on the floor and the boat to heel like crazy).
