      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. Foiling Moth Setup

    I'm sure you've found several helpful videos. Here's a good one (even though it's over a year old) showing one of the more complicated setups. You don't necessarily need all the same gizmos, but it might help you understand more of what's going on.

    Dashware doesn't have to take such a long time. If you start your video with a short segment showing the GPS time from your cellphone, the sync step takes almost no time at all. And if you only overlay the data on short segments of the video that you want to include in your edited version, that doesn't take long either. Here's one of many short clips I've made to help evaluate gybing technique on my Moth (Note: this is not me; it's someone who knows what he's doing).
  3. Hi Doug, Tech problems.

    I have the original A14 eXploder used by Matt Struble from NAs 2015 with Jz boards and stock eXploder fins, superbendy Fiberfoam and now a good DB sail used by Craig Yandow. Foiling is very difficult. I can sort of make OH's boat go, but mine...not so much.  

    1. OH says I need to move the board trunk forward 5 to 10 inches to make it work, and use Z10 foils at least.  The problem is that I can move the trunk forward only 5 inches because of the shroud base and its bulkhead. In your opinion is that enough to even bother with?

    2. I didn't find any Z10s yet: inquiries from attendees at SD= nothing. Do you know of any?

    3. I am ready to add sail extension to make a decksweeper from a good older skinny top sail (2004 near NA winner: Woody Cope's).....just to have something that works*. 

    4. This sounds sort of silly, but how about moving my rudders further out back (6 inches with extensions) for as is- Z10 same trunk position*.

    Comments welcome. 

  4. VPP for dinghies and skiffs

    GPS Action Replay gives an estimate of the TWA. Of course, its accuracy depends on having a big enough sample of data points & how steady the wind actually was.

    Granted, it's hard to say what the most important factors were, but it may not be a coincidence that the only 2 DNA F1's in the fleet finished 1st & 2nd. The attention to detail in the platform aerodynamics is very impressive. In contrast, the 3rd place Exploder was at a bit of a disadvantage, having torn his lower tramps on the 1st day & was sailing most of the series without them. But who can say how big a factor that might have been? And what about the narrower square-tops on the F1's? (See the blue boat in the earlier post by Lost in Translation)

    Just so this thread isn't left hanging, here are the final results: https://sdyc.org/assets/results/results17/a-cat-na-res.htm
  7. F18 ownership costs

    How many Moth sailors have shore crews? None that I know of in my club. F18's are great, and I don't want to say anything negative about them, but they're a lot more trouble than Moths in all sorts of ways.
  8. A-Class North American Championship by San Diego Yacht Club

    This is the "non-foiler" mentioned on the front page.
  9. A-Class North American Championship by San Diego Yacht Club

    Correction - actually it's in south San Diego Bay.
  10. Radio Control Multihulls

    Do you collect any data from your tests? Speed, at least, is easy to get since there are now small, light GPS units available. Getting forces might be more difficult.
  11. Sail twist simplified

    That's really not very good advice, BobBill. Beauty is in the eye of the beholder & I'm sure there must be some who think this Snipe's sails "look good".
  12. Sail twist simplified

    What assumptions did you make about the velocity gradient in the Earth's boundary layer. In other words, what was the difference in true wind speed & over what distance?

    What's a Cb?
  14. Foiling in shallow water

    Mach2.3 Vertical is ~41 1/2", measured the same way. The older Mach2 vertical is ~2" shorter, I believe.
  15. The winning foils

    I find it pretty strange that you're using the past tense & referring to Moths as "ancient foilers." The class is doing just fine in many parts of the world, and the boats & foils continue to evolve. Nevertheless, I'm curious about Gacking too. I know it has been done in the Moths, but I wonder how common it ever was & whether its use has diminished as the best sailor's ability to do foiling tacks has improved. It would be pretty incredible to see one of the AC teams pull it off though!
