    Looking at the jib knuckle (such that it is) there must be a bucket load of tension on.

    Many years ago a well known Fireball team replaced their rigging to lenticular solid instead of wire strand. The added shock loads tore the spreader roots out. Lessons were learned and carried forward. Good contemporary examples are carbon rigging and wings on a wide stiff light base like a cat - the shock loads go straight to the foils. Britannia's design (starting from the bowsprit) indicates an emphasis on a very stiff boat, albeit more difficult to sail. Such a break can indicate their design is successful in terms of generating rig power and importantly, their control systems are up to it.

    Must be putting some huge loads on it getting that mast to twist properly and their boat must be super stiff. And here vid from Renishaw (additive titanium printing among other things) showing VR of Brittania, effort gone into test boat etc

    Video's my business these days and your channels quite good with respectable viewing figures, especially considering you probably haven't spent thousands marketing the shit out of them.

    More than possibly not. They talk to each other so Ineos might have been the catalyst and the F50's are interesting as they are a developing one-design class. They could be in a position to lead or be part of a syndicate.

    That could well open doors to say, Artemis, Franck Cammas and perhaps Ernesto.

    20 mm is a lot. For example in 470's, a strict one design, enjoyed a hull tolerance of 5mm along with proviso extremes should not be used. During the late 70's three designs (at least) reigned, Pajot Fountain, Vanguard and Parker. I sailed all those designs in quick succession during Olympic trials and it was remarkable how they differed even with the same rig and boards. All three had slightly different hull shapes and all three had different handling needing different techniques and different rig configurations. Mackay NZ came on the scene in the early '80s having built new moulds adding a fourth hull design. These days 470 hull designs are closer still and each have their peculiarities. Even in the 70's bolts were hollowed out and weight gains were measured in grams. Every mm and gram counts and is especially relevant when speed goes up. There's an interesting Youtube on Hugo Boss on how they looked at saving grams throughout the build process. A 20mm drop in the mast base, especially in an AC75, affects everything right down to rudder control and rig configuration.

    Showing just how low they've managed to get the mast base. Every mm counts.

    Quattro chiacchiere con Max Sirena, parte prima. La vela giovanile italiana Italian only https://youtu.be/546-N7w4kq4 ""Here, please, no photos" Max Sirena is proud when he takes us inside the shed where many technicians, like doctors in an operating theater, work under and above the big black "monster". He is keen to show his creature and the heart of the Luna Rossa team. But later, we will have time to steal photos of the boat in action. Seeing her locked in a shed is like seeing a dolphin in the pool: dolphins were born to jump into the open sea. . . . . . . . "

    They made the mast base as low as possible and put some effort into low windage forward of the mast. Windsurfers know how critical this is to handling and control and one of the top IMCO 60 guys pointed this out very early. To stay within the rules extra volume needed to be added, have high side sections aft. Side effects include your points plus they've been able to stream airflow along the hull, protect the crew and no doubt other stuff we can't see including rig configuration benefits from such a low mast base.
