    1) James, I haven't lost interest-I'm just mad at this one design horsemanure.....
    2) I've seen that board in a picture but don't have a clue-wouldn't they all be the same?

    About the numbers of viewers compared to VO70; the answer is simple and nothing to do with one design, VO70's were racing for how long? - nine months? with the media (doing admittedly an excellent job) covering the personalities during the long race period. Also they have a "granny" who communicates light stuff to the general public - hit mute to the prattling.
    So the MOD70's cross the Atlantic two ways in a couple of weeks - and race back in a few days; it's a no brainer. This was a sprint and they're too fast for their own (media) good. You need time for the populace to figure out what's going on ... and maybe require the insufferable granny to boost viewer numbers.
    The MOD70's are a way superior boat, light years ahead of the VO70's and should take their place; much faster, smaller crews, maybe considerably cheaper (taking into account VO70 breakages) - the list is long - welcome to add to it.
    Only be a matter of time before the heavy motor sailing dinosaurs are converted into cruising boats or maybe gutted for floating restaurants ... or the useful parts recycled at the scrap yard.

    I've looked at detail at the daggerboard and cant see a trim tab on it. It looks like the daggerboard sits in a shroud maybe it's sacrificial to protect the hull? I guess it's possible that the board rotates inside the case a few degrees but they have made no mention of it. Due to the one design rules either all the boats have trim tabs or can rotate their boards or none of them do it's possible but I cant see it even when they are flying the main hull.

    It looks to me like they made the best tactical decision in heading north earlier and pulling out a lead the others could not drag back. Experienced and well drilled crew pushing really hard seems to sum it up. Over 25kt average is really impressive as is the Atlantic in less than five days.

    The dagger bloody board, James, as I see it, is standard; there are no trim tabs, no two, or three, section elements. I think what you're mistaking as a leading edge element is just a restraining/positioning line running down the side of the board.
    Now the curved foil is much more interesting; it does appear to have a twist. Are they allowed to modify their appendages?

    I've emailed the MOD70 organisation to see if they can forward a copy of the rules and measurement details for reference.

    ========
    ONE......DESIGN......! See how interesting it's always been to dissect the designers choices and how they influence a team??!! Oh woe is me-I guess I just miss the good old days of influential designers and builders creating special boats tailored to special teams. I guess I miss the learning how those designers made the choices they did and how the teams used the advantages they were given. It's a damn shame....
    Oh: congratulations to the winners-whoever they were..........

    Just saw your post, Corley-great idea!

    I wonder who we could recruit to be the MOD70 version of the prattling granny? MOD70 is in need of someone to step in like Volvo and inject some more money into the organisation it's hard to see that happening in the current financial climate though.

    Yep, I think they should go for the sponsor pinch!! I would not be surprised if Volvo would consider it seriously. Audi used to be heavily involved in yachting sponsorship but have wound their commitment back massively over the last few years.

    Here is the finish video from the MOD70 site on youtube (gives better video performance on my computer).

    Mod 70

    From Scuttlebutt last night:

    NO GUTS - NO GLORY

    French skipper Yann Guichard and the 5 men aboard Spindrift racing won the
    Krys Ocean Race, the transatlantic race between New York and Brest (France)
    for the MOD70, a new class of 70-foot one design trimaran.

    Looking at the race tracking page, it's possible to drag the progress bar
    to see when Spindrift got the advantage on the 2,950 route. Now we learn
    how they got the advantage:

    "It actually all comes down to our ability to stay longer than anyone under
    gennaker on the second night of the race," explained Guichard. Winds were
    really blowing hard as we entered the low pressure system and we were
    picking up speed, close to 35 knots. The sea was still very calm and flat
    so we pushed a little bit harder than any of our competitors. We were able
    to combine great boat speed and a better wind angle. We slid downwind the
    entire night and in the next morning, we were in command, on a better
    course with greater speed. It was then all a matter of keeping that
    advantage ."

    Concerning the life conditions on the MOD 70, Guichard warns the ride is
    not for the timid:

    "We've been under water most of the time," Guichard said. "Big waves kept
    spraying the cockpit and the man at the helm was the most exposed. We've
    stayed wet during the entire race. We were quite tense at the beginning as
    it takes a while to get used to high speed sailing. When you do 35 knots
    and over for hours, you get the feeling that disaster awaits at the next
    wave. Then you kind of get used to it, you build up confidence and you keep
    on pushing hard. At night, things really get stressful as you can no longer
    anticipate the direction of the waves. I know all the MOD70 have had their
    moments of sheer fright, when the boat hits the wave with three hulls and
    boat speed drops from 35 to 5 knots within seconds. You wonder which side
    the boat is going to fall. And then you just keep on going."

    MOD 70 Rules

    Received a copy of the MOD 70 Rules from Corentine Lemonnier, Executive Assistant -see below. I haven't had a chance to go over them yet:

    It's as watertight a One Design Ruleset that I've seen. No changes in appendages or profiles allowed there is however this section under Foils. So they are allowed to adjust the longitudinal positioning of the foil.

    B-3.7 Foils
    Longitudinal adjustment is freely up to each team but must be set at a fixed value for
    any given event (Ocean Race – European Tour – Ocean World Tour or others). In all
    cases, the minimum setting allowed is 2 adjustment wedges of 20 mm forward of the
    foil. The adjustment chosen by the team will be checked before the start of each event. A
    foil must not be lifted beyond the capacity of its lifting system.
    B-3.8 Centre-board
    The centre-board must not be lifted beyond the normal capacity of its lifting system.
