      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. 2017 Rules Rule 69

    This is one way. Know how your boat works, and your mates' boats. Pity the only audio is the ratchet block! skip to 20 secs, for the impatient.
  2. I14 Capsize Compilation

    Could this be the, ah, target manoeuvre?
  3. Not seen everyday

    Well I hope there's a windward mark ahead to help with their navigation. Otherwise they're heading to the Sandhills on Moreton Island, not Stradbroke Island.
  4. AC36 Protocol - Ask Dalts

    Why 75 ft? at least, 72ft is the size of another maxi class.
  5. Legal "Wingmast" for I/14

    That sounds about right.. The sail that wasn't bad but I reckon it could have done with less seam shape and the draft forward. Change the setup to run with more Cunningham on in general (so you're never in the position where you're sailing with a loose Cunningham). Had a battle with batten stiffness for a while to get the cams to rotate evenly, and the right amount. Also adjust batten stiffness so the leech was twisting / opening correctly through it's range. I'd stiffened the mast once by vac bagging IM uni's along it but it needed more stiffness, it was hard to get the setup going well with a bendy mast. Adding a Carbon track later helped things along immensely! i14 masts probably a good candidate as they're already very stiff, although not sure whether the high hound position would work. A stiff mast with an even bend profile probably better than the flexy tip bend profile (think latest moths are going this way coincidentally). The straw that broke the camels back was a nationals race a couple of seasons back - a Gusty front came through changing from 5-10knots building to 15-20knots offshore just after launch time. Everyone had their big rigs loaded, then did a last minute change to second rig as the change became apparent. We need about 5 minutes more rigging time than other setups so couldn't risk missing the start. A quirk of the rigging sequence meant the kite needed to be rigged after the mainsail (halyard had to come through the pocket), making the rigging sequence more sequential, so more difficult for two people to rig the boat independently. again, this won't be a problem on an i14!
  6. I'm not yelling

    With only two people on board - I've had a couple of funny experiences where I've said to someone new 'quick do this now' etc.. They haven't done it, instead during the time spent asking why we're in the drink. Centreboard is a great spot to chat!
  7. Legal "Wingmast" for I/14

    Yeah - It was fine last time I looked at it but agree now its shit! will add re-hosting to the list I think there's a lot of points well made in this thread... and thanks for the compliment Daniel! Definitely getting plenty of fun out of her. Now have two toddlers so development has somewhat slowed these days. To Team GBR - while I agree there was more to get out of the (pocket) rig, the question was what could be improved on the rig to make it faster? It essentially worked as intended, the mechanics were fine and the sail set reasonably well, (and after a couple of seasons perfecting details) only the aero (&elasticity) would be improved. Why would a pocket luff sail look different to a conventional sail with a pocket on it? The solution (a conventional sail in a track) was a much lighter, flatter sail on a stiffer mast with more area in the square top head. It's pretty fast now although the luff round still needs a half inch +- here and there. With no initial performance difference with a pocket, developing the pocket further seemed only a slower more expensive route to achieving the same % improvement. If anyone is interested, I have 4 carbon cams to suit a ~55mm Mast, and matched NC machined alloy moulds to suit both a 55 and 65mm masts, iirc. Their section shape was roughly based on what Tom Speer published on wing mast shapes, 10-ish % chord ie ~2-2.5m chord sail. PS.. for an i14 wouldn't you optimise three different rigs for light, medium, heavy wind depending on whether the worlds were in UK, Perth, or SanFran?
  8. Legal "Wingmast" for I/14

    I sail a 12' skiff and built a pocket luff #2 main for it (about the same as an i14 main, but slightly less powered up). Long story short - solved the problem, and it worked pretty well. Made my own cams, had cool spreaders to deal with the pocket, re-luffed the sail to suit etc. Wasn't any faster, couldn't tell the difference. There may have been a slight advantage if you're overcooked and trying to pinch upwind. I think for moths it can generate more camber, ie more lift offwind, but we have spinnakers so it doesn't matter. I have reverted to a normal sail in a track and focussed on rig dynamics, twist, perfecting leech tension etc. I spoke to Alex Vallings about his same effort on the 18' and his conclusions were uncannily similiar. 'no difference, just a pain in the ass'. Some benefit if you want to 'zip in' a different luff round if your number of sails are limited (do i14's let you change luffs on the main?) Fill with water when you capsize, heavier sail, harder to tune, more sailmaking to get right, slower to rig. Leeward separation bubble can go suck itself! Some babble on it here: http://z10.invisionfree.com/12ft_skiffs/index.php?showtopic=551 Some pics here (my photobucket account seems to have choked): http://s981.photobucket.com/user/BG_172/library/Tank Girl rigs http://s981.photobucket.com/user/BG_172/library/Tank Girl rigs?sort=3&page=1
  9. Do the sock-length arc thing as above.. I have three points on our big kite. The sock can go as long as the floor is, our sock is tied to the aft end of the rudder frame. When tieing the retrieval line, tie (say) a 100mm loop in it, so the first retrival point comes in earlier than the upper retrival point, which spreads the bunching out a little.
  10. The foil of the future

    L with variable angle in the L? plus solar powered hamsters
  11. The Pulse 600 Saved My Life

    I've only see one sailing from a distance on a windy day, and it looked pretty placid in decent wind (like the photos posted). Kite I saw was a very conservative small fractional asso.
  12. Sailing Yacht A Under Full Sail

    Maybe it had a touch too much weather helm so they're going easy on the mizzen Or they're trying for a little self steer to go easy on the autopilot
  13. Means of propulsion

    Like this thing. First seen on South Park?
  14. Means of propulsion

    Sorry I wasn't clear, I was referring to the foils. Pumping the foils may be more effective than pumping sails if you have an accumulator to store the energy lost on the return cycle, as a spring would. Cyclists only need to supply the energy lost per pump cycle as opposed to the wing, which is a total loss system with no accumulator
  15. Means of propulsion

    Interesting stuff. A couple of thoughts.. when I've been riding, going from full power to stopped isn't always a pleasant feeling, whereas spinning the pedals at no load helps keep your legs warm and the lactic acid moving along. Also, a quick (very rough) calculation, based on the power output table above.. if each cyclist can momentarily put out 1200w (20w/kg @ 80kg), x4 = 5000W (5kW) The mass of the boat say 2500kg + 500kg wing + 500kg crew = 3500kg = 34300N Power = force x velocity => Velocity = Power/Force = 5000/34300 = approx. 0.15m/sec. So they have the power to lift the boat vertically at 0.15m/sec. Not fast, but interesting nevertheless as in combination with an accumulator etc. it could be enough energy to affect the hull kinetics and bounce it up or some such, a co-ordinated movement with the wing, or good dynamics to provide that little extra during a roll tack. For example, if a tack takes 1 second, 5kW input means you could theoretically be 0.15cm higher on the exit of the tack (assuming you've worked out a way of physically doing this )
