      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

  1. Yep, called a whipstaff
  2. you could actually put the tiller under the deck and just have an arc shaped slot in the cockpit sole. Much better for moving about in the cockpit. In fact with a bit of cleverness you could just have a straight slot across the cockpit.
  3. Good point on the collision of boxes and one-design constraints, but I'd suggest that the current one-design platforms are already being subjected to stresses that weren't envisaged at their design. As I understand it the whole nose-down attitude is about maximising the righting moment generated by the windward rudder given the fairly tight limits on its rotation about a transverse axis. This trick was discovered by teams testing the AC45 platforms at some point and it seems the rule designers hadn't planned for it. I'd suggest a future platform could be designed to cope with a theoretical righting moment that gives teams plenty of space to innovate, and hence focuses innovation to desired areas, which could change from cup cycle to cup cycle. As a bonus such a platform would then be very durable and could be re-used over several cycles a-la VOR65. Weight would be a bit of a penalty but not a huge one. Or alternately, as you suggest open up certain dependent components such as beams to permit a broader range of innovation. As to the wings, am I right that the aerofoil section and planform are one design, the construction and contol systems aren't?
  4. +1, unless we can man up and make it J Class...
  5. Aerodynamics I'd say
  6. Reality is that in foiling world smaller is better as aerodynamic and hydrodynamic drag are the critical factors at such high speeds. The AC50 cats aren't any slower than the AC72s from the last edition, arguably faster. Chances are that a barely limited DOG boat would be pretty small, have just a single wing and would not be that spectacular to an untrained eye. Crew members would largely be parasitic weight if you consider that dropping the windward foil on a cat and tilting it back as is now done with the rudders could create masses of righting moment and power, far more than the weight of a crew.
  7. Hmmm - I've noticed that too, but i'm 6' and 95kgs. I guess it comes down to the ratio of wave drag caused by moving denser water to wave drag avoided through less hull immersion in denser water.
  8. Variable foil geometry from "normal" to supercavitating and back again would be way cool. Would possibly require some form of controllably deformable flexible material that could then be locked into shape, perhaps via electronic current. Isn't going to happen soon, but it could happen eventually. Computer controlled foils has to be the next big thing. The tech is already on the water - didn't I see a cruising cat featured hereabouts recently with computer controlled foils? Basically a sophisticated multi-sensor autopilot laid on its side with clever predictive algorithms and maybe laser height sensing, intertial inputs and some kick-ass actuation with no hysteresis. Would definitely need stored power to be safe. This one isn't much of a stretch at all. Fresh would be all over it. Computer controlled wing might be another useful avenue to consider. I know the French are playing with electronic telltales already.
  9. It's not a Travel Agent sketch it's the Argument sketch!
  10. It's been a long while since I studied deep hydrodynamics so not sure how significant the impact of salinity / density / viscosity on cavitation would be. My gut says pretty small between fresh and salt water.
  11. I've long wondered why the steering foil hasn't moved to the front, and indeed the lifting foil too. Maybe it's just a matter of time. A successful amateur yacht designer I worked with as a teenager designed a 12 metre concept with both the rudder in the bow and helm station ahead of the forestay back in the late 70s. Wacky, but the logic was impeccable at some levels. Until I pointed out the risk of a bow-on collision and that the helmsman would need a wetsuit and diving mask/snorkel combo and couldn't yell at the crew as he wouldnt be able to see them. As to supercavitating foils, I doubt that will ever happen on a racing boat simply as that type of foil simply hasn't an operating range wide enough to deal with race course realities like starting, mark rounding and tacking/gybing. Given that, it's unlikely we'll see foiling race boats ever go much faster than the high 40s or low 50s when cavitation kicks in. Naturally a record setting specialised "boat" like Sailrocket is another story and I'm sure there's still plenty of room for innovation there.
  12. Here's a basic AWA, AWS and VMG Calculator. Pretty impressive numbers I said it was BASIC!!! So no current, leeway involved! My top recorded speed is 32, in pitch darkness at 1am in the middle of the ocean surfing down a wave in a 40 foot yacht. Might have gone faster on a Tornado catamaran at some point however.

  13. At the risk of sounding self-satisified, the Australian accents are as often as not found in AC team brain trusts. Just as well, as there's essentially no hope of getting an Australian AC team up these days, the public interest and support simply isn't there and is diluting further every day as Australia becoms more diverse and multicultural. I went through school (literally) and did my early sailing with and against Fresh, Iain Murray, Glen Bourke and Grant Simmer to name a few...yet despite my efforts to get them hooked on sailing my sons are both elite football (as in soccer) players.
  14. Wondering if it'll become a pro-am or even Corinthian race sooner or later? Bye Bye Clipper?
  15. Good point!
