    The title sais it all pretty much... The idea is "a pure recreational warm water swimming by using whatever wind is available in order to propell a person with a sail."

    Can it be done with minimal rigging and gear? ( suggestion of using arms, legs noses and other bodily parts are not welcome :)

    Cheers!

    Have you heard of kite sailing, apart from that where do you put pole, mouth, belly button or .... @@@ .

    Yes, it could be done. The system was described by Jules Vernes.

    But what if the swimmer got all-to-excited and as a consequence, the mast collapsed?

    Never thought about that. Probably have to drift around for a while then try again.

    Body parts are not what he wants guys!

    But the human body does have a socket for a mast. A 1 inch broomstick, rounded for comfort and a pair of suspenders to keep it upright, that's all you need.

    I would suggest a surfboard a critical first step, a mast a second, and a sail a third. Otherwise consider kitesailing.

    The human body doesn't make a good hull. Rigging to human flesh will kill you as well. Suggest wind surfing, kit sailing or perhaps building a small sailboat. The smaller they get, the goofier they look.

    Hi JosephT,
    I see that "April Fool" is making progress (backwards judging by the bubble lines in the water)... I wonder that a coracle has not been suggested - being non directional circular in plan view?

    Just out of curiosity, how can you tell which way is the front?

    In response to the original proposal (contrary to post 2, 4-10), floating on your back and travelling downwind would work with a simple "fabric between 2 poles" sail.

    I am not sure of the potential for navigation, but the variance off of dead down wind would probably be small without additional items. Some "fins", one on the back (daggerboard function) and one on a foot, might aid in navigation ability, but the whole idea begs a "Why?" before any further consideration.

    I shall not post the picture here as the puritans here will get a heart attack and the just as puritan moderators delete the post, but us, Frenchies, all had a big laugh when famous magazine "Charlie Hebdo" published this drawing on cover page after Tabarly double dismasting in the Withbread round the world race, and continuing under jury rig !

    THAT is a human swimmer using small sail for propulsion!:D

    I have used a kayak paddle to propel me forward while swimming, I have also done it floating on an inner tube. I do not see why a small sail will not work, but it would only be good for downwind movement at best.

    There was a rather inventive fellow that joined within the last year that had a cleaver idea for a kind of half sailboard that you lay on top off, with your legs and feet hanging off the back, using swim fins to steer with. It seems that would be a better approach than just a sail with the swimmer floating on his back. With a short board at least you could rest, and you would have more ablity to tack into the wind.

    "Can a human swimmer use small sail for propulsion?"

    Of course they can.
    This is the function of the Bicorn hat as developed by the royal navy and used for a century to aid swimming sailors.
