      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 options on tracks, but we think Ronstan do some useful specials. Getting front and back to move in unison will be essential but again, there should be a solution somewhere.
  2. The challenges are about handling and coordinating tacks and gybes. We had this debate but concluded that a prototype was the best way forward. The prototype will have a Tornado rig, or similar, but all else will be as per that original picture.
  3. But you would lose massive amounts of time stopping and reversing. Not a problem when you are sailing across the Atlantic on one or two tacks, but not racing round the marks.
  4. 400KEu! Hang on, let me check the back of the sofa. I hope someone has that kind of money. I don't think we have had a champion not defend their title before in C class.
  5. "unhinged British yacht design", - there has to be a pun there on John Downey's "the hinge", but I don't want to see SHC split his sides laughing. :-))
  6. I think it's less complicated than foiler like Groupama and hydros. I think it's less complicated than foiler like Groupama and hydros.
  7. Yeah, but being AC means we will never get to see it.
  8. Here's the early sketch
  9. Paul Larsen shoŵed me happy feet when I shared the initial sketches (see picture). He had been thinking along parallel lines. Yes, LOTS of training, and getting wet a few times also! I'm not clever enough to do the maths to work out dynamic stability, but having long legs should help; it's easier to control a bike with a high cg rather than a low one, but we are just going to have to find out. T foils will also help I think, as they are still efficient in mid manoeuvre.
  10. Kites would be illegal in c class. I remember reading about a cat called Jacobs ladder (with stacked kites) at Weymouth speed week. The picture showed it heading to the heavens, and the pilot falling in mid air about 40ft above the waves As for shifting the geometry around, I think centralising everything is a matter of releasing a cleat, but we will need mechanical advantage to haul back out on the other side. Thank goodness this is a 2 man boat!
  11. Technically it is, but it's a foiler first and foremost. Measurement is interesting, but I have cleared it with our measurer. Hulls are usually sized to provide full buoyancy on one hull, but I need both hulls to stay afloat. I've kept cost down by making the hulls symmetrical about a horizontal plane, so I only need one piece of tooling.
  12. DS for tacking/gybing, yes, as you say, I think centralise, execute manoeuvre, then reset to opposite tack. We need some tips from canoe sailors! N
  13. Thanks Steve, we have made the tooling for hulls and beams and foils, and a few sponsorship leads following the show.
  14. THAT IS DIFFERENT! and much more conceptually valid. You will have a good time building it, I believe your structural team will be burning a lot of computer time because the mechanism is not trivial and the consequences are pretty unpleasant if it goes even slightly wrong.Good Luck.

  15. Ok, the picture doesn't show everything clearly. Rigging - there isn't any (the lines u see are trapeze lines, but I forgot to draw the rings etc on the leeward ones), and RM, well the racks, hulls and beams slide on curved tracks on the inside faces of front and rear beams. Yes, the foils are a bit long, but not ridiculously so; our RM is not compromised. The drawing shown is v similar to Will Sunnucks Vampire conversion which appeared at Foiling week.
