Superman Board

The superman board is a small wing towed behind a boat at low speeds. It allows a person to travel underwater holding their breath for surprisingly long distances due to the low physical effort required when compared to regular free diving.

The blue board is a fourth generation superman design. You simply hang on to the front or the handle in the middle, tow it SLOWLY behind a dinghy, take a big breath, push down, and suddenly you are flying underwater with a feeling much like Superman flying through the sky! The pink board is a commercially made board, but I don't know it's name or origin. Although slightly more maneuverable, it requires higher speeds that put too much pressure on your mask. It's still fun though!
