I've been experimenting with a hydrofoil with a monofin. I hold and control the foil with my hands with my arms fully forward extended (the foil is about 3/4 of a pool lane width, wider than a hammerhead). Using the board I get more power into the monofin (and stress on the feet). Swimming under water I have the foil "up-side-down". Foil photos: http://www.fastacraft.com/moulded_foils.html, and this probably performs similarly and differently than the "waterwing" http://www.janploeg.nl/english/waterwing.html.
Has anyone else tried a hydrofoil with their monofin?
