    I love to follow the small boat projects, including AIT (Around In Ten), but I think a max 1,000 kg weight limit for a circumnavigating challenge would be a better idea than a max 10' length limit.

    Like Sven suggested here . . . quote is almost from the bottom of the linked page

    Quote: ‘‘ . . . I prefer to see an around-in-one-ton-race (metric) a race based on volume, not length. . . . ’’

    Anyone know a good acronym for this ‘‘ Around-In-Max-One-Ton-(metric)-Total-Displacement-Circumnavigating-Challenge ’’ . . ? ?

    Maybe AIT (Around In Ton ;)), or AIOT (Around In One Ton), would be something . . ? ?

    No way.
    The tonnage represents the sum of the volumes of the internal spaces, tightly sealed to water, of a ship or of a vessel or of a float of any type. His unit was registered tonne, a unit of volume equivalent to 100 cubic feet (2,832 cubic meters).
    So i can have a boat 1 ton, inside, but add close volumes (example in foam) to ten meters flotation long ...

    Hello Folks :)

    I have deliberately stayed out of this conversation for one simple reason, I am flabbergasted, speechless and dumbstruck. In other words: I simply don't understand what is going on or what went wrong. I have read every word over and over again, and nothing makes sense at all.

    What does "lost interest" really mean? Just that?

    Yrvind Ten is a good boat that simply lost its identity along the way, too many changes, some good, some maybe not so good.
    BUT having said that I would have suggested to Sven to "simplify" AND FINISH the Yrvind Ten. At least just sail her and have fun with her, you don't have to go on a 2 year trip around the world and break records. Just take her out for some 1 week or even 1 month trips and enjoy her in and around your local waters.

    Yrvind Ten is a good boat and I think she is fantastic, she deserves to see the water, even if she does not have a "push the limits" new design rigging, a short mast and simple sails is all required.

    Building a "ten" is very expensive and takes a huge amount of effort, but my partners and sponsors were told that from day one, so no problems there. And we are very aware of the fact that there could be complications, but somehow somewhere we also have to do crazy things, and simply have fun. Life is short, live it and enjoy it.

    And what keeps me going is simple curiosity, nobody is really sure how well a ten will or wont sail. Lots of armchair "experts" and when you enter into a sober debate you discover that they actually don't know and are guessing. The real problem with a ten is that it has no commercial value and hence definitely no re-sale value - and that is actually the deep rooted human condition against "wasting" money. The harsh truth is that all boats are a hole in the water into which you pour money.

    And that folks is the price we pay for our love of boats :D :D :D

    Have fun and may you have a happy weekend.

    When there's only a weight limit (Around In One Ton) then length is not an issue . . :idea:​

    The weight has nothing to do with the tonnage formula.
    This weight formula is madness, it means that the steel boats are forbidden?

    There are 2 ways to approach the AIT; the way Manie is doing it, in the spirit it was intended, or the way Yrvind tried to do it by bending the rules.
    Perhaps the AIT rules regarding the ten ft boat lenght isn't the best way to determine the "size" of a boat, perhaps volume is more accurate,perhaps weight is more accurate but the bottom line is that when you participate you should accept the rules in the spirit they have been made in. If you find it difficult to recognize the spirit than you belong to the "winning is the only and most important thing" people,regardless of what it takes.......

    Yrvind is a great sailor, a great designer/boat builder but he completely messed up with his Ten project, or better, the way he tried to "explain" the how's and why's.
    If you start questioning fellow sailors like Spiess and Testa, well.....

    Sorry. 100 Cubic feet does not equal 2,832 cubic meters. It actually equals a little less than 3.0 cubic meters. Oh. I see. you put a comma where a decimal point should go.

    As for a name for this proposed class, why not call it the "1KK" class, if going by displacement, or simply the "100 class", if going by enclosed volume.

    The problem is that, just like with a 10 ft hull length, the the 1 metric ton and/or the 1 shipping ton limits, are both arbitrary.

    I can just imagine what a boat following either one of these limitations would look like. It would probably be low sided, long, narrow, and have a schooner rig. Or it would be a multi.

    The mono version would resemble a long raft with a coffin perched in the middle ;)

    No, when talking metric, Windraf placed a comma where a comma should be placed like in 2,8 M3.;) (just joking but it's true)

    It 's really funny that you Americans with the tea party have not thrown at sea also the imperial measurement system :D

    Spiess and Testa didn't go under any rule, so Sven isn't questioning their achievements. Sven's argument is that the length label that retrospectively got stuck on their boats, in relation with the later evolved AIT (Around In Ten) concept, is standing up for discussion. It's just a matter of which length is right to measure under AIT rules. Sven's point is how we should measure ‘pre AIT boats’ in relation to AIT which arose later.

    Sven explained the ending of his TEN-project very well to me . . . :idea:

    Quote:

    ‘‘ When I started with the Around in Ten I had not studied the legal aspects of the race. Rudders are buoyant extensions not measured, so are hulas but all this is no fun. It leads to unhealthy boats. Yrvind Ten would in reality be legally about four meters long with the extension and I do not think I would be proud of cheating, therefore I decided to build a smaller boat. ’’​

    If Yrvind Ten is legal under AIT rules stands up for discussion, and Sven is not proud of doing it in this controversial way and therefore he ended the project.

    no, he decided to build a bigger boat, not smaller:
    even by measuring his new boat with Thames tonnage, taking external measurements it is far greater than 1 ton;
    flotation is 50% longer than a ten;
    and the displacement is a hoax: the pounds are declaring where he drew the line, but the new boat is in its water lines also charging twice the weight.

    A boat is not only defined by length, by means of displacement the new boat is much smaller than Yrvind Ten, whether you agree with it or not . . :eek:

    if he builds the ten in carbon fibers and draws the water line to an inch from the bottom, it will have a boat 'infinitely small', if this is the logic :D

    Yes that's the logic with displacement, but it wouldn't be wise changing only the building materials without changing the design, because if the only change is just floating higher than it will influence the boat's behavior in a negative sense, I think you knew this already . . :idea:
