      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. Perfect angle - thanks. Doesn't matter which foil let go - if leeward rudder then windward one would be overloaded and stall out and then for sure the rig moments take over both transverse and thus heel, and longitudinally and stuff the bows and goodbye Judging by GD's charming remarks I reckon that was a direct bullseye:) I rest my case m'lud.
  2. That was very careless - they should know not to run into another set of foils wake at a shallow angle, turbulence, aeration and the vorticity off the leading foil set will totally disrupt the normal flow patterns. Plenty of aircraft have been flipped A over T by tip vortexes. Sail any foiler and try and run it behind a rib propwash and soon find that out - can cross at steep angle OK with a brief excursion but they shot themselves well and truly in the foot there. Still, go get 'em the Kiwis, anything to get the cup away from Oracle and the poodles please!
  3. Hugo Kirby and ? ( can't remember his name! ) were the co- owners, Bob Fisher was asked to drive it, I got a call from Fish on the Monday and flew to Japan on Friday! Hugo would remember I'm sure - think I've got his email somewhere....also memorable was one of them throwing up over the back just before the start of race - big night it had been:) Hell of cast of entrants though - Hughie Treharne and other reprobates on SeaPly, John Kolius and many others... Careful there..that would be a Rule 26 infraction. SeaFlyer if you please. Correct - they had to change the name there:) Bit harsh with the Japanese full works teams well in evidence! We were all a bit envious to see their boats taken over by a team of white suited shore crew at the end of each race...

  5. Wings! Did the Sajima Worlds with The Fish and the two owners - was an epic series and very possibly the best ever. Long race was fun, racing between unlit islands in the middle of the night and full on thunderstorm...Fish comes back up having had a few hours off after just about getting knocked out...."where we going?"...pitch black and blowing a bit...bang and lightning flash showed up the islands..." head for the gap Fish!" Endless stories from that regatta - some repeatable, some best not:) Playing football with a lighted flare on top of the hotel at the end of the saki evening...low parapet...still got the saki barrel too! Wild racing though, Kolius nearly drowned trapped under the wires when the boat tacked on him, lots of retirements and general carnage.
  6. Maverick - mainsheet trimmer lost two fingers in a FU so they had to pull out and head for Nevis and land him.
  7. Excessive leeway?? Let me correct you, DSS foil has the lift vector arranged to be approx vertical at normal sailing angles, so has no effect on leeway.
  8. Send money first and join the waiting list:)
  9. Yes Michi has been racing lake of Zurich and doing very nicely thank you, check his website...
  10. Around and available, would be perfect base under new rules asits the lightest mini out there, v quick if it goes light, foils will do the work and could cant as wellif you wanted todo more than the transat. Tra sat only then fixed keel and keep it light light light.
  11. Pleased to say that this is the beginning of an ongoing collaboration for DSS with SeaAir, and foils derived from my Q23 developments.
  12. The deck spreaders are quite famous for catching stuff and getting damaged in the IMOCA fleet. They have ended several VG AFAIK. The IMOCA ones are all cable braced and the cable itself is low on the hull for the attachment and hence is vulnerable to passing objects. Brett has borrowed the idea for solid deck wings from the fully researched 100 I did way back as enc pic.
  13. You'll have to excuse me if I don't elaborate in detail on the foil geometry, but it's not that straightforward as to how and why it's configured in this way, and the 3d was an early look at how the geometries of boat/structure/foil might interact - a lot different in final build. However a key issue is that we don't try to combine lift/RM with sideforce as the Imocas have done, as this leads into some undesirable characteristics which they have certainly discovered by now! So structurally of course the loads are maxed at the hull exit and the foils themselves have to live with this and that is part of the loops you have to go around on foil sizing for structural as well as hydro reasons. Don't want taper as such as we want to maximise the RM. I don't care about a tiny portion of the foil being outside the hull when housed - even on the Q28 with quite a chunk exposed it was hard to see the speed cost in the lighter airs and there are more pressing reasons to keep as it is.
  14. This early development pic might make the foils a bit clearer as to how the are housed - these are simple line driven although for the Farr 53 they are intending to have the single classic DSS board drive power operated - which is what we did on the earlier the 36. My Infiniti 46 though is derived from the very effective Quant30 I did with this foil configuration some time back, and has some significant advantages for this particular boat and how it works. In practice these are extremely easy to deploy and retract as you can move them into position fully unloaded before you tack or gybe, and then deal with the other after that has been completed.
  15. 8 TWS is enough and can then be heading uphill at 12+ or so - water conditions permitting as ever - and from what we can judge so far then CMG is about 3-5 lower than a conventional boat doing its 6/7 knots or whatever. We don't have instruments on the boats as yet - one of them probably will get instrumented soon and then be good to know exactly what is going on. Almost impossible to really judge against normal boats as the speed differential is so high. Also depends whether sailing 2 or 3 up, wind gradient and all the other stuff so it's never a fixed number. Top speed that we know of from the boats so far was 26.8 but 20-25 knot range is commonplace - I had 25 pegged as the sort of top end we were after, could go faster if we took the bulb off:) Hull is almost all glass.foam.epoxy, about a kilo of carbon around wing exits/chainplates to get loads out into the rest of the structure.
