    World $ailing will do precisely nothing - they need the $$$$ from AC. Bob Fisher got it right and then the riposte from the W$ bean counters was classic accountancy obfuscation.

    Correct, but they sued him anyway, ditto for GM too when it was really a design config FU seeing as all the others had similar issues. The foils in the pic look very much like the originals, and would make sense to stick with those to get a better idea of how they work against the latest generation to take that knowledge into the new boat and configuration.

    Complete bollocks:) They designed a Mk2, and it lasted less than a couple of hours so stayed with the Mk1. And then sued the builder of the foil - dunno what happened finally but they were also busy suing Green Marine and GM went out of business. Wouldn't have been time to build any more as these things are extremely costly in time to build as well as $$$$$$$$$$$$$$$$$$$

    but not from Ineos - its a Diam 24 rig!

    The Haas tunnel is a standalone for vehicle testing and would a lot of additional equipment to run any meaningful yacht tests and I very much doubt they would go to that tme, trouble and expense and then have no time for their normal clientele. Done more than a bit of tunnel work and CFD will be the route here I'm sure. Oracle's twisted flow tunnel is probably the best, Auckland one after that if you are after aero testing. But expect the Kiwis have that one sewn up for themselves!

    So Charal averaged just under 18.5 which doesn't seem that quick for 20 knots of breeze. Looks impressive, but a hell of lot of spray which is indicative of a lot of wasted energy ie drag.

    wtf is Vrolik doing there though? The hull is pretty irrelevant and he's done nothing with foils and has condemned foils on boats in no uncertain terms in the past! Still, sure that a few $$$$ will help him overcome his principles:)

    Another keel fell off

    well if that keel wasn't changed after the Hooligan one fell off then it was going to fail sooner or later. Read the report.

    indeed! These will be extremely susceptible to impact damage, and that can/will be from waves as well as more solid objects. We know that waves took out foils in the last edition. There are times when you really don't want all this stuff hanging around out there.

    Doen't have to be of course not, but that's how it is at the moment. Trying to get away from the video game aspect of sailing that they used in the cat

    But, and its not a small but either, the supplied PLC will have a random reaction time delay in there so in theory they won't be able to chase the dot on a screen to keep the thing upright and at the best height. This is an unstable system as soon as you fully submerge the foils and say theres a max of ? 1 second or even half that, then it can all go pearshaped in that timespan at those speeds. One would have to presume that our Kiwi neighbours have already figured a way around that. Or have they? Maybe the huge roll and yaw inertia from the ballasted arms will slow things down enough to make it sailable? But for sure, if it does get away from you then it's beam me up Scotty time.

    Twin skin no, they have a standard Diam 24 rig in the boat. And it should look stable, the autopilot is running 2 axis in roll and heave so they only have fore and aft as manual. I would lay long odds on the rule getting changed to allow that on the full size versions a well.

    Pogo vole !

    thats only the arm supporting the underwater Tee foil same as the arrangement for the AC boats- but I reckon this is vapourware anyway.

    Wrong. This is showing fully immersed working foils a la AC, and these need to have constant active control. If they are surface piecing then you can have natural stability along with the rudder Tee. Hydroptere was surface piercing. The only reason the UK test boat is working is because it has an autopilot for roll and heave and the sailors have trim via the rudder foil. AC75s and then crew has to control it in all axes and good luck to that frankly. Would not be at all surprised to see rule change for 1 or 2 axis flight controls.

    pretty fuckin stupid for a Mini as the foils will need active controls, and the SeaAir one is self regulating
