Why I'm Following Sven Yrvind

Do you believe Sven's latest Ex Lex will make it to New Zeeland.

  1. Nope.

  2. Probably.

  3. Almost certainly.

    I have to agree with at least some of the criticisms levled against Sven. He does seem to cherry pick to prove his points.
    But I'm really following him to see how his design ideas work out. They are as contrary to status quo as one can get. Modern sailboats go with tall, Bermuda rigs and ever shorter, deeper keels.
    He goes with almost ridiculously short rigs and no keel at all.
    There may be some real world (beyond Sven) applications of his ideas.
    It seems that the now three Ex Lex have evolved to a very singular type.
    This is:
    1.) narrow for its lengnth,
    2.) very small, short rig,
    3.) multiple masts,
    4.) centerboard way forward in the bow, and now
    5.) twin fore masts.
    When I look at these design characteristics, I wounder how they would work out if they were scaled up and were slightly more beamy, say having a beam of 0.20 length instead of 0.17.
    Suppose we scaled it up to 50% more length, which would make it a 30 footer. Then, there would be a lot more space on board. and the greater length, combined with the narrow beam, would make it a very efficient powerboat. Put in a small engine. Give some good sized fuel tanks. And keep its sail rig, but just scale it up 50%, so the sail sizes stay in proportion to the size of the boat.

    This would make a very interesting motor-sailor. And it would be very easy to handle out at sea.
    It would motor with its tiny engine until the wind got strong enough to make this difficult. Then up would go the sails.
    In storm survival conditions, the sails could be all furled, and the bow centerboard could be lowered. Then, the boat would likely heave to without a stitch of sail up.
    Or the centerboard could be pulled up, and the twin fore masts would keep it pointed down wind, if the situation required this.

    There is nothing wrong with the idea of small and skinny as far as easily driven goes. A Scilly Pilot Gig can attain double figures under oars in bursts, and quite easily under sail in a breeze; certainly much safer to do so if it was decked over.


    Paul Fisher did an updated version to take an inboard, it would make a very easily driven boat that would clip along at a good pace using very little fuel.


    I hope his boat works out. Not everyone though wants or could travel in such small boats. he is small himself.
