      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. A big challenge is to coordinate sheeting and steering, and that can only come from practice and knowing exactly what each other are doing. I don't know about the open leech, once foiling it should be closed, it's why Moths run massive vang tension (since multi-style travellers don't seem to work as well). The SuperFoiler has some moments when everything goes right, they just need to bottle that and learn to replicate it. The mainsheet trimmer and helm should be right next to each other so they feel exactly the same things and learn each other's responses. I think the windward heel is a good idea, with the dihedral on the wings it will be difficult to sail flat as the foiling cats do. I really hope they get it right, but it's a huge challenge.
  2. Hasn't the foil finish thing been done to death? Smooth is ultimately faster, but (very slight) roughness might be more stable if draggier at the top end. See this windsurfer thread, which has a pretty reasonable discussion, even mentioning Frank Bethwaite—he reckoned smooth is fast, but what did he know? So a matt finish might be a little more stable, at the expense of a tad more drag, which might be a good trade-off around the course. Or not.
  3. On Mac undo is Command-Z. The "Source" button is removed, can it be returned please? If it was available I could interleave quotes and replies, rather than having to rely on people working out what the reply is to. Inserting replies into quotes using coloured fonts is rubbish as it defeats quote markup.
  4. These guys are sailing the boat like a Moth, that it's a trimaran is pretty irrelevant. The more windward heel, the more vertical the leeward foil so more lift to windward and more vertical lift from the tip. Heave stability seems to be an issue though. I don't think this would work with a Z foil where it would increase lift to windward but lose vertical lift. Seems to be bow-up in most videos, level or slightly bow down might be faster but I guess it's early days. Source: youtu.be/yMe5TGGEOdA?t=18s
  5. If it makes any difference, on a Moth with the wand disconnected you might as well not have a horizontal foil at all. Even in very flat water with 12 to 13 kn boat speed, there's no perceptible lift. This also means it's impossible to sail downwind with no flap or the wand disconnected in breeze over 15kn, it just stuffs the bow in because there's not enough lift from the main foil. Even if you get up to planing speed (say 13kn or so), crank the rudder to give max down force and hike as hard as you can off the back corner of the windward wing, as soon as you hit the back of a wave, over you go.
  6. If you ask Moth sailors they'll tell you that tipping the boat over is far better than having it sit upright on a trolley with the rig up in any sort of breeze. Most (all?) skiffs are rigged lying on their side, it really isn't an issue. It just needs a bit of cooperation between crews to fit everyone in. There is no reason that insert from below boards should require a boat to be launched on its side, or even capsized to fit the foils, especially if there's no wand or linkage to connect. The hull just needs to be lifted, the board inserted and fully raised, then the hull lowered again. The beach wheels might need to provide a bit more clearance, but that's it. If the A Class allowed insert from below boards, it would free up the shape of boards. Whether that's a good thing or not I don't know, I'm just saying that insert from below should not be seen as some huge issue for managing the boats off the water.
  7. The surprising thing to me is the amount of apparent bend in the starboard rudder relative to the main foil, though not much of the vertical is visible. Or are they canted too?
  8. There's no way you can determine the angle of the rudder stabilizers from that distorted pic. Look at the torsos of the guys in the background. He's been told that before (also here), for the same image (which is cropped from a larger image). The lens distortion is huge. And without any reference points, control or lense calibration data, making any claim related to accurate measurements is laughable. But that will not deter him.
  9. That's the crux of it for me. It doesn't matter if the foils are Z, J, L, whatever and are a little slower in straight line speed, their ease of use and lower cost is a huge bouns. I hope multies continue with development of wandless designs. The progress so far has been amazing and there is every indication that they will reach a level comparable to current wand controlled T foils, but without the added complexity and cost. It may mean that A Class has to modify their rules to a 1 metre gap rather than 1.5 m, but that's not an issue for other classes (or new ones).
  10. Looks like you're having fun with some great wipeouts! Please keep the videos coming, they're great entertainment. You're right to concentrate on boatspeed to get foiling, focusing on windspeed is not very precise. When a wind guage somwhere reads 5kn average over a few minutes, there can be lulls of 3kn and gusts of up to say 7kn or more. So saying "It can foil in 5kn" is really just an indicator, but onoce you find the boatspeed you'll likely get it down to ±0.5kn very reliably. It seems to me that there's not enough mainsheet action. Try and keep the boat very flat, don't let it heel to leeward as it greatly loads up the leeward foil. As soon as it starts to heel, drop a bit of sheet and as it starts to roll back to windward, sheet on again. Going downwind in particular it's very difficult to feel the wind, you have to respond to pressure on the rig and the feel of the boat.
  11. I think it's about the huge change in apparent wind strength, not angle. Foiling upwind at say 15kn in 15kn of breeze (to be conservative) means say 22kn across the deck. Downwind in the same breeze at say 22kn or more and the apparent is about 5kn. So smaller rigs tend to be more efficient upwind, but lose downwind to the extent that they are generally slower around the course even though boats spend about twice as long going to windward as they do downwind. That was true for Moths and seems to be for As too, but there's nothing to say it won't change in the future. One thing that hasn't been shown lately is the current shape of A foils, everyone's been quite secretive about that.
  12. You can't tell much from a single, short video where there are so many unknowns. The A may be going low to sustain foiling and may well point higher in displacement mode. Or not. Certainly the twsited main isn't helping.
  13. I don't think scenarios 2 and 3 can occur given that promotion to the semi-final is "…based on overall series ranking", not where they finish in the semi-final qualifier. As long as the course is even with fairly steady breeze and currents, it could work quite well. It would stop the leading boats match racing each other to the back of the fleet in the final and put some focus on other sailors as they battle to make it through to the medal race.
  14. Hmmm… https://commons.wikimedia.org/wiki/File:Yacht_Coronet_(1885)(Detroit-Publishing_Co_1894-LOC).jpg Not sure about "…better to fill the triangle between the plumb bow and sprit with boat" though (socalrider, post #9). ;-) Also shows how to deal with an anchor with a plumb bow. Might need a few more hands in the fo'c'sle though.
  15. Geeze Phil, your sarcasm–O–meter needs re–calibrating…
