    They were SMALL, 18' to 20'. Back then they would try anything once or twice. As tactic pointed out, we did not have the materials to pull the ideas off. Few ideas ever reappeared again.

    Langmans "Innerview" on SA

    As I suspected Langman is really into exploring the use of hydorofoils .Wouldn't be surprise to see them on the new boat. He talks about the concept of using the wide beam to keep the boat level -something like 18 crewmen sitting outboard + the canting keel.
    He likes the idea of the boat sailing upright with little or no heel to get rid of any downforce from the sails.
    Steve-no "tease" apparently...

    Lets see--- a canting keel and a----canting crew and a-------- canting foil. Anything that can keep the mast vertical develops more speed in any wind direction and at any wind speed.----Don't forget the canting rudder.

    Fantastic Dinghy?

    A while back I posted "On Deck Movable Ballast" which included a dinghy proposal similar to Bethwaites Pterodactyl except that the wing containing the ballast moved side to side along with the ballast so that at max extension there was nothing to leeward.
    After seeing Langmans proposal and thinking about it a lot it seems to me that maybe I had it wrong. From the standpoint of safety and ease of sailing maybe having the wing fixed is a better idea. It's an important change because for it to work as well as the original idea the wing will have to be twice as long. But the ballasted daggerboard could now be eliminated(or not ?) in a version of this boat between 14 and 18' with a net reduction in weight from the original.
    The buoyancy pods would be higher than on a Bethwaite HSP and would be designed to be used only to keep the thing stable while the crew boarded and as a backup in gusts. I think performance would be degraded letting the pods act as amas so they would have strictly a back up role. This version might be safer and at least as fast as the original idea. It would surely be fun for anyone who wanted to sail a planing hull fast but didn't want to(or couldn't hike).
    Multi or mono it's bound to be fast....
    Any relevant comments appreciated....

    Maxi Skiffs

    Has anyone read or heard any more on either of these projects? I'm impatient to see one of these extraordinary boats on foils or even "just" sailing!
