      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

  1. There are a few spots where these boats can leak. We changed a few details and tuned up our bonding procedure to solve the problems. We have instituted the old Vanguard leak test in our QC checks. We cribbed directly from the Europe Dinghy Class, not just because we had the kit left over from when we built Eropes, but because it turned out to be a very good way to determine if a boa leaks. Bubble tests are good at finding leaks, but you can miss a leak, so you need a more global test which establishes if the boat leaks or doesn't leak. We pressurize the hull enough to achieve 130mm differential on a water gauge. That differential shall not fall below 50mm in 30 seconds. We are doing this on all new boats so we can tune up the assembly and assure the customers that the boats are watertight. The suspects are usually the scuppers that drain the little hand hold "kiss offs" on the deck, or a small void in the bond of the watertight bulkhead just behind the mast. Both are pretty easily fixed. SHC
  2. Seats extend the same distance from centerline, so should be cross platform compatible.The only caveat is that because the new boats can be narrower than the Nethercotts, the actual extension out the side of the boat is greater. 750mm beam compared to 1014mm beam. So the seat is cantilevered about 130 mm more on minimum beam boat than on a Nethercott. The measurement of all of the bits is pretty much identical between the one design and the development rules, rig height, centerboard depth, sail area, seat extension etc were kept consistent with their historical precedents. I rounded some things off to more convenient numbers, but the intent was that any boat that ever measured in would continue to measure in. SHC
  3. And from the old man. We will sell the DXF files and a license to build boats at US$ 100. Because someone will inevitably want to build a carbon fiber one, I will sort out a set of external frames that the panels can be fit into without using the internal structure as the building structure. Should be pretty easy. The elders are thinking nice thoughts about a little more stability. Remember that the olddevelopment rule allowed boats as skinny as the new rules (750mm) and the boat that emerged as "best compromise" was 1014 mm wide. So I had been meditating about what I can do in a beamier hull form. It will probably give something away upwind and in a short chop, but There isn't much slower than a capsized IC. I have an idea, based on Lou Whitman's Phoenix that was probably faster than the Nethercot in 1970, but never got much of a chance after the ICF made the Nethercot the only approved shape. Willy is playing a little fast and lose with his Dad's time. We always get excited by the World's and unfortunately, the either energy of the event dissipates or my contributions somehow miss their mark. The result that I spend a bunch of time and money creating something that nobody wants. I am pretty addicted to my own dope but don't have much luck getting others to take a taste. SHC
  4. I know I tried it on half a dozen models when I was a kid and it didn't work as well as putting weight on the high side. Of course where I lived, it blew hard almost all the time, and ithe only reliable way to make one of my sailing models go faster was to put shifting ballast on deck, or in many cases further to windward on outriggers. This was the only way I ever got my free sailing models to plane upwind. Which WAS pretty cool when I got I got it right, about once a year ........ SHC
  5. Simple nationality rule: crew must speak the native language of the competitors nation during competition. Artemis speaks Swedish, SoftBank-Japanese, etc. At the very least this would give the national teams an inherent relevance to their nations. As I see it, Dalton wants first pick of all the Kiwis without having to bid against those from other nations who might pay more. So it is at once a cost control scheme and a way to ( if you believe that New Zealanders ( like vegans) are just better) to deny the competition access to the best. This is only true if you are addicted to a certain flavor of Kool Aid. Back in the dawn of time, when Hood sailcloth was 1000% better than anything else in the world, this was an absolute advantage that the NYYC surrendered only after the development of film sails and the advantage was worthless. Each team did their own development though. All major components, like winches, spars, and steering gear was all CIC. As a fan of these things, I really liked the creativity and diversity this encouraged. It is easy to imagine that this was good for the marine industries in the various nations, and that the benefits outweighed the costs. I mean if the richest people ina particular nation are going to wank off into the Auld Mugg, isn't it better that they spend the money in their home country in the native sailing businesses? Kind of a service to the home boys. SHC
  6. The deepest the boat can get is 54 inches ( 1370mm or 4'6) This is when you are way aft with the rudder all the way down. The rudder is 6" deeper than the main foil In this attitude your speed will be as close to 0 as it gets. Generally speaking 4' of water is enough unless you are flying, then something like 18" is deep enough if you are good enough. If you stop, make sure you tip over to windward or it can get expensive. SHC
  7. Biggest problem with the 49er singlehanded is righting the boat. The rig is really big when on its side and sometimes a single monkey doesn't enough avoirdupois to stand it up. Can get very boring before it gets very expensive. SHC
  8. US1 was mo less a cut down Windmill just as the Banchee was a cut down FJ. US 1 wasn't a bad boat sailing boat. Of all the Laser clones of the mid 70s, they were in the top 5 or so. None were better than the Laser however. SHC
  9. M. Taunton is correct. Ther was lots going on with Australia II that had nothing to do with hydrodynamic breakthroughs but with optimizing with the 12 meter rule. So much " advancement" is like that, unfortunately. If I recall correctly, the Meter rule essentially trades sail area against length and weight. " Small" boats get big sails, "big" boats get small sails. In light air, the small boat wins, As the wind builds, small boats run out of stability and don't have the righting moment to handle the additional sail area and lose to bigger boats. By messing with the keel profile, Australia II easuered smaller than she actually was. Also by having so much lead down low was abnormally stiff for a "small" 12. So she found a sweet spot that Liberty could not match in spite of being aggressively "moded" for each day. This made possible by having multiple measurement certificates for each combination of sail area and displacement and length. Short of all that, there is some difference between bulbs and wings, although each is "just" a tip detail. The IACC boats all had wingletson their bulbs to clean up and organize the vortices coming off the keel tip. This is a deep an complex rabbit hole. We are still waiting for some of the guys to resurface. SHC
  10. All most all foil designs are constrained, to some extent by Class rules. So the present successful solutions have to be considered within the box they live in. A Class limits horizontal span and bans surface sensing wands. AC boats ban 4x4 configurations , and flaps. C Class limits beam. GC 32 are one design. So to consider what is really possible and what may be a "best" solution you have to look someplace other than racing classes. The problem with that is that there is no testing. Ellway's Vampire is one such out of the box example as is the Seafoiler, where the designers have sought practical answers without the type forming constraints of fair racing. From my perspective, flaps flaps flaps flaps. They are proven to quickly and reliably alter the lift of wings. The loads are small, and can be rapidly actuated. There are some difficulties in construction, but those hydraulics were not cheap either. SHC
  11. How about a national language rule? If you require the teams to speak the language of the nation they represent on the race course? The French were the only team not speaking English. The America's Cup isn't an equal opportunity employer. The Aussies and Kiwis are very territorial and have very sharp elbows and give hiring preference to their mates. Make them learn Japanese if they want Japanese money. SHC
  12. I thought you were looking for advice on how to do it fast. No shit, a hammer is a good weapon for getting tabbed in bulkheads out of the inside of a fiberglass hull. I would not have cut them down as much as you did because it reduces the leverage to wrench the tabbing up. If you can find a "slick" which is a great big chisel about the size and weight of an axe, they also do a good job. These are the weapons shipwrights carry into battle on their backs. Short of that, a masonry chisel or jackhammer bit that you sharpen with a 5" grinder makes short work of it. A sawsall, which a long blade is also a good choice if you have to reciprocate in order to get your craft on. The long blade will slide back and fort along the skin and get you almost all the way there. Or, carry on, you are doing fine. SHC
  13. A 20 oz hammer does a really good job. Seriously, wail away, stuff gets loose and can be peeled off. SHC
  14. Merde! Really? SHC
  15. If you have any interest in history, the New York Yacht Club was presseured to constantly lower the nationality barriers in the interest of fair competition. The US defender selection process was the only competitive racing, which meant that the defender had a more fully developed program than any of the challengers. By and large this was successful, participation in the Cup grew from few US syndicates and a single challenger to vital challenger selection series, and finally to the current state, where a single defender is at a disadvantage and writes the rules that breaks down the barriers of challenger and defender. The vision is a competition between teams, not a competition between nations. One can see that several "nationalities " are merely "flags of convenience" and don't even represent the nationality of the owners or sponsors. There is nothing Swedish about Artemis, and ETNZ relies almost exclusively on foreign sponsorships. BAR and Groupama are closest to the original spirit of the thing, with mostly domestic sponsors and lots of national representation in the design team and sailing team. Groupama was the only team not speaking English. Oracle is at least funded by US money, and the design team has US leadership, the sailing team dominated by antipodians, but this is true of all of Ellison's racing efforts. He has embraced the Pacific. A move to strict nationalities would be wildly unpopular in New Zealand. There isn't enough employment in the current America's Cup for all the Kiwis who want to work there. Make it so that they can only work for ETNZ and you will even less popular than Coutts is now. Unless you do something really crook like exempt New Zealand from the nationality rules, or require ALl teams to have boats built in New Zealand and have 85% Kiwi content and sailing teams. Or better still, send money, we will take care of everything else. It will be fair. SHC
