    Beautiful. Always seemed like an event when she came in through the jetties when we hung out at the harbor.... Then saw her a couple of years ago in that god-awful cartoon livery on a trip with my kids to Santa Cruz just before she headed back east and she just didn't look like anything notable. Love to show my family what she is supposed to look like in her appropriate dress.

    Regarding the plexi shield... I'm sure that is not some temporary afterthought.... you can tell it is retractable as it is not up on the lee side of the cockpit.... I'm sure the driver wants it up to cut the wind, but it appears flexible enough that if you slammed into it in a sudden decelleration, it would give without destroying your face. It speaks to the extreme attention to aerodynamics that even such small shields are only employed when driving on that side.

    Really awesome:

    One of the things I thought really interesting is the comment about moving the pod forward reducing the pitching... which counters the concerns some here have voiced about having the crew getting more pounded with the living area moved forward.

    Really interesting: Coville says the central pod weight amounted to 25% of the weight of the hull, and they have shifted it to forward of the mast, nearly over the centre of gravity of the boat. The effect of this is that it lowers the centre of effort down some 2 metres and reduces pitching moment. .... The other knock-on effect is that it allows the boom to drop to almost flush with the deck, which radically changes the aerodynamic efficiency of the sail. Coville estimates that it reduces airflow disturbance and increases the efficiency of the whole sail area by some 20%. The rig height can also be reduced. ... “And then – today we’ve got T-rudders to put the boat [back] on its nose because the foils, most of the time, are pushing too much,” he adds. “Suddenly, you align all of these [forces] and you don’t need to have such big rudders, so you reduce also the drag on the water. “So everything, by one change, makes the spirals suddenly better.”

    Now that Sodebo 3 is officially out of the barn and out on the water, maybe time to spin off its own thread, rather than talking about her in the Ultim Development thread. And to kick it off, a video:

    I just realized they don't have a casing for a retracted rear foil like we see on Gitana and saw on PB's now-dead boat.

    Actually, not true. The amas on a tri are significantly less in wetted surface than a cat hull, so much of the time, a tri has less wetted surface than a cat. The weight is also pretty similar, as the beams are not as heavy on the tris. So, boats like BP3 (I think that was the original name of Spindrift) and Groupama 3, specifically built for crewed racing, are still tris, not cats.

    I don't think the placement of the cockpit represents much more pounding on a boat going as fast as these boats are going, particularly when foiling... even when in archimedian mode, it is not like some slow mono where the bow is bouncing around and the stern sits in a trough. When up & foiling, I don't imagine that placement represents any more pounding at all, as the boat is slicing through and rolling over bumps rather than pitching and pounding.

    Obviously, the point is to put the mast near the center point between the four foils, and to provide as much safety from pitchpole as possible. Makes a lot of sense to me. Especially if you are Thomas, who had to live with a nightmare of a pitchpole machine 2 boats ago.

    Doug Lord must be pissed. No FireArrow royalties from this.....

    FP, whatever that is, calling it "ugly"? Man, I think that things looks awesome.

    And when you are sailing for 40+ days, non-stop.... the "sailing experience" is, shall we say, achieved, even with an enclosed cockpit.
