First of all, I don't have a Sunfish, I have a Viking which is almost indentical. The board on the left in the picture came with the Viking. The board on the right is a Phantom board. The Phantom board is slightly longer and has more of a foil shape. I don't know if the Viking board is original. It has been repaired (one of the handles) so it may be. I have not sailed the boat yet, so I haven't tried either board.
