    Team NYYC

    My old machine shop teacher would have a bit to say about using a ruler to drive screws :-) Cheers, Earl

    Seems reasonable to start with ballast, sort out the righting moment in displacement mode, and then switch to foils. Cheers, Earl

    Enlarged version, lightly tweaked for your viewing pleasure :-) Cheers, Earl

    Port Tacking the Feet.

    Dunno what happened here, but this is the picture.

    Port Tacking the Feet.

    Happens in radio racing too. Here's Ned Lakeman port-tacking the fleet in the 1999 Vintage Marblehead Nationals (he came in second that year). Cheers, Earl

    Interesting New Lifesaving Device

    Vendor site with demonstration. U-shaped, self-propelled, radio controlled life ring. Toss it in and steer it to the MOB. (The only thing I know about it is from this link.) Cheers, Earl

    Rough guess using Google Earth's measuring tool is that the area with the Union Jack is about 120 feet wide. Cheers, Earl

    The new sailing twin skin setup

    L F Herreshoff's Live Yankee was different from all in Groucho's diagram. The mast was a D, it rotated, had dual bolt ropes and the double luff extended about 1/3 of the chord. Another interesting thing about that rig was the jib, which had a rigid, double luff, rotating "jib stay." Cheers, Earl

    I was referring to the technology base. Once a part of that is outsourced, it is practically impossible to pull it back in. The outfit you outsourced to will see to that. (I worked for one of those, and making the customer dependent upon us was basic to our business plan and our number one marketing priority.) The other stuff you mention are parts of the supply chain and you can force them inside national boundaries, or at least try. Cheers, Earl

    An amusing discussion, but IMHO irrelevant. It's as if there was a Tutankhamun Cup, and people were arguing whether the hieroglyph for "build" included "design." The simple fact is that the context in which the DoG was conceived and which remained in place down to the time of the 1958 NYYC resolution no longer exists. That context was made up of distinct, national technology bases, each of which was "truly representative" of a particular nation. A 1958 Toyota was "truly representative" of the Japanese automotive technology base, as a 1958 Chevrolet was of the American. Globalization killed that context, never to be resurrected. This is true not only of maritime technology but also automobiles, civil aviation, and electronics. A 2019 Toyota is no longer "truly" Japanese any more than a 2019 Chevrolet is "truly" American. A race between two vehicles carrying those labels (which is supposed to happen next year in NASCAR) is about as far from a "competition between foreign countries" as you can get. So all that we have left is a Victorian jug with no bottom and a bunch of people trying to figure out how to monetize it without melting it down. So far that has not been a particularly edifying spectacle, at least to me. Cheers, Earl

    The new sailing twin skin setup

    L Francis Herreshoff did a double luff main with rotating mast and rigid jib stay in his "Live Yankee," designed in 1927. Plus a flexible "fish tail" rudder and the highest ballast ratio the R Class had seen to date. Got the rig design made illegal by the NYYC for his trouble. Cheers, Earl

    If the loophole closing was the result of somebody reading this thread, I think I deserve at least a gimme cap from ETNZ Not holding my breath. Cheers, Earl

    I see the loophole in the clause on crew indication devices (allowing mechanical versions) has been removed. Damn. And here I had already blocked out a nifty pitch-and-bank indicator with a Tesla turbine running on compressed air and driving a mechanical gyroscope, for sale to the highest bidder. Cheers, Earl
