      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. On page 23 of the October/November Pro Boat(#169) there is an illustration of a "ring" canting keel exactly as depicted in N. Flutter's rough sketch inspired by my original 60' Moth concept 7 years ago but this time patented by Vlad Murnikov in 2013. Murnikov says: "Unlike a conventional canting keel there is no large opening in the hull, and structural integrity is fully preserved. And with a modest internal moter you can rotate the ring and place the keel at any angle you want: 90 degrees, 120 degrees, anywhere you like."
  2. Wouldn't work with just a rotating canting keel-needs on-deck sliding ballast as well. The scow model proved the physics of the combination of fixed keel and Trapeze Power Ballast System(on-deck sliding ballast) resulting in over twice the RM than from the keel alone(with the same total weight) AND self-righting: Would definitely work on a fullsize boat:
  3. Most impressive! What is the wrist watch type thing above?* The camera superimposes the GPS data from its own internal GPS? *Just looked it up: a remote view screen...
  4. Something you know all too well!
  5. Can you turn the prop mounting axis to simulate leeway?
  6. I did a pretty detailed analysis many years ago of the idea of a 60' monofoiler with 90 degree canting keel and sliding athwartship ballast using a bi-foiler foil arrangement: https://www.boatdesign.net/threads/60-or-20-ocean-racing-monofoiler-design-discussion.15143/page-12#post-428215 Sketch by N Flutter of his take on my concept:
  7. I bet they all adapt Verdier's solution!
  8. Mostly new Gitana 17 video from Guillaume Verdier-probably the top foiling trimaran designer ever: http://www.guillaumeverdier.com/maxi-trimaran-vole-litteralement-dessus-de-latlantique/
  9. Great work, Hydroptere-like the wing!
  10. I have an exact scale foiling RC tri, Keith- and I'd be glad to show you some pictures-interestingly, there are now two fullsize tri's using the same basic system first invented by Fire Arrow:
  11. Way to go, punk. You locked yourself in the crazy room for all to see. ------------------- My thread* on boat design is about 7 years old and is not the first thread where I proposed what is now the basic Fire Arrow Foil System used by Fire Arrow, Maserati and in its finest conception yet by Guillaume Verdiers Gitana 17-one of the coolest fullsize trimarans ever designed. And all three of these boats use a basic foil configuration with details never before seen on any trimaran anywhere at any time. Not in the 50's, 60's, 70's, 80's 90's -NOT EVER! They are examples of a revolution in trimaran foiler design with features on all three never before used together on any size foiling tri. Again, a fucking Revolution-that the punks and old men have no clue about whatsoever!!! * My thread is one of the longest and most detailed to be found anywhere but the real thing on boatdesign is that there is no attempt to claim any intellectual property at all-it is an attempt to present new ideas that anyone is free to, and encouraged to copy. Further, I already had four letters patents when I started that thread and instead of publishing every detail of the Fire Arrow concept I sure as hell could have patented the concept-but I didn't want to-I wanted to give back to the design community and inspire others to think outside the box that trimaran design has long been wedged into. And I did it while developing one of the most significant foiling trimaran concepts ever- PUBLICLY. And a couple of the top foiler designers in the world have seen the thread and the resulting Fire Arrow Foil Concept Test Model and told me that it was just great. So the half-ass comments by the punks and old men are simply meaningless drivel as far as I'm concerned.

  12. You calling me a liar with such a profound compendium of made-up bullshit is hilarious and sad. You are full of shit.
  13. Some new(I think) video: http://www.guillaumeverdier.com/maxi-trimaran-vole-litteralement-dessus-de-latlantique/
  14. You have no clue-just more poorly thought out punk kid bullshit!. I did my absolute best to copy the best elements of the TNZ UptiP foil with other components I introduced like washin, iFLAP , a unique planform, and horizontal foil droop*. The fact that my foil works so well on Fire Arrow is testament to the brilliant invention by TNZ as well as to the specific elements of the design I incorporated on the Fire Arrow-which in your punk-kid-idness you have no clue about. Many other designers copied the basic elements of the TNZ UptiP foil which was in the public domain-I introduced many changes to the basic TNZ-type foil that help it to work exceedingly well. * compare the pictures-much more droop on my foil. My UptiP ama foil design was the FIRST such foil ever used on a foiling trimaran ama in the history of mankind!!!!
