You need about five strong guys. At the factory, they rolled the boat with a large tire (w/o rim) located so that the chainplate is in the center of the tire as the boat goes over. From there they place a very sturdy support under the bow eye, and two under each corner of the transom. These were well padded and roughly followed the deck contour. There was also a pad over the tire to prevent black marks on the boat.
I think the boat is around 675 lbs without the board.
Be careful not to bend the chainplates over.
