    ....got stung by the 'WASZP'?..OD foiler...

    When I first started building my moth in 2008, I had never seen a moth before except in pictures and videos. When I launched the boat the first time I was guessing how to rig some of the parts and had just a vague hope that many of the systems I built would actually work. The only thing I took with me on my first sail was the information that I’d gleaned from the internet and the encouragement from the online moth community and SA. I was foiling on my first day (until some parts broke) and attempted a foiling gibe on my second day. When people ask me “is that hard?” I say it’s like riding a bike. If you try to learn how to ride a bike as an adult, it will be tricky and you will fall but you’ll figure it out after a while. Once you feel the balance of the boat it really isn’t difficult (except foiling tacks, those are feaking impossible). Once you fly there is no going back.

    What Phil sail. If your boom is at the bottom of the sail you get all foot tension and no leech tension. If you had a crazy wishbone boom that attached to the top of the mast you'd get all leech tension and no foot tension. Put it in the middle and you get a bit of both. Changing the amount of outhaul could pull both the foot and the leech, which may work fairly well.

    Ya, I have to agree with that. Dropping some of the strings and the making a less complicated rig it a good idea, but I doubt the boat will be any easier to sail than a Moth. It's a cool boat though, I'd buy one.

    Ya, this is getting pretty ridiculous. The boats are on display tomorrow with racing starting Sunday and all we have from AR is 'early July.' If these guys want the world to take them seriously they need to get on it.

    Seriously guys, the AC 45s are one-design cats that don't meet the letter or the spirit of the Americas cup. Why not just give up and sail J24s or Optimists for the America's Cup? Making significant changes like that at this late date is impossible. If you delay the cup this event is ruined and the AC will never recover. Game over.

    Sad news. Do we know if it capsized and then broke or did it break up first then roll over?

    The fact that they admitted that the boat is in the shop for mods means they have some hope of making some successful changes in short order. Maybe change the boxes a bit and then cut four feet off the tips of the foils and glue them back on Oracle style. Modify the rudders and hope it all holds together. Could work.

    ==================== If those are fences they seem too high up and too close together? No fences on the rudders, just two red lines painted chordwise From today Well that's dissapointing. I was getting ready to hope these guys had a chance.

    A lot of foiling boats like Hydroptre use fences on all of their foils, they help prevent ventilation of the surface piercing lifting foils. If the rudders on AR aren't designed for fully foiling, a fence may improve their performance when they are partly out of the water. If the leeward hull is in the water the hull acts as an end plate and a fence is totally unnecessary. The only time a fence is necessary is if the foil is surface piercing, so unless the fences are to help flow over the rudder on with WINDWARD hull (which would be pretty weird), they almost have to be for foiling.

    Why would you put fences on the rudder unless you were planning on having the rudder fully loaded and partly out of the water? Getting ready to fully foil?

    Artemis?

    I can see the logic there, but I think you run into a big problem with this setup when your hands are tied with respect to the AOA of the lifting foil on the rudder. If you have the rudder supporting a large portion of the boat in the air then you'll need to set it at a higher AOA to achieve lift-off. This higher AOA will produce more drag when not foiling and has the potential to create too much lift at very high speeds. I suppose you can control the AOA of the rudder by changing the angle of the entire platform, but thats probably quite tricky to get right. The NZ system which relies more on lift from the main foil and just uses the rudder to regulate pitch with a lower AOA will probably provide more steady flight. Which will be faster around the cans? Who knows.

    It's interesting looking at the main foil position between these three boats. Assuming that the weight is distributed relatively evenly between the boats, then I don't see any way OR or AR will be able to foil with much stability with the main lifting foil that far forward. Sure you can put way more lift on the rudder to compensate, but without being able to easily control the lift from the rudder on the fly I just don't see either of these boats flying like the NZ design.

    Actually I have an idea of why this may have happened. So when you vacuum bag a convex surface the bag pulls (is pushed actually) onto the curved surface. Once the film comes into contact with the surface and begins to apply some pressure the composite material is compressed slightly. On a convex surface this results in slightly smaller total surface area so there is no tension on the bag. But when you compress the concave surface the surface area of the composite needs to increases slightly as it is pushed down (not much, but a bit). With the bag firmly pressed against the hull at this point, the bag needs to stretch slightly all over the surface to accommodate the extra area created at the moment of compression, which would produce a slight bending force. Possibly.
