  1. And that's fine, but two yachts on a pleasure cruise heading in two different directions in what sounds basically like open water should never be in the position they need rules to avoid bumping in to each other. There are two fundamental principles I live by out on the water: 1) I have ultimate control of what my vessel does and does not do 2) until proven otherwise, the other guy is an idiot, act accordingly if you don't need to be in the same corridor then don't. If you do, make your intentions clear, loud, and early, and only assume the other guy will respond if t
  2. Where T.F is Cid Harbour? I mean, i grew up halfway between brisbane and hammo, thought I had sailed to most places on that strip of coast. Never heard of Cid Harbour. Gladstone or Keppel would be about half way. A few sharks, and less crocs but just as many box jellies as Airlie...
  3. Yup.... Always assume the other boats will do something stupid and act accordingly, Ideally well before you need to.
  4. I dunno, it sounds like the other boat is being precious to me. Assuming both boats are keeping a proper look out then the risk of collision should be low, unless one or boat are limited in manoeuvrability. If you are looking out, then you have to assume the other person isn't. you're both out for a casual sail, it sounds like it would have really been no skin off the other guys nose to pinch up a bit for a ways out to make sure it was a safe crossing. Also, they don't know if you're stuck on a particular heading so can't manoeuvre. IMHO if your are pulling the colreg
  5. PS, I'd be stoked to have a boat called a Navier...
  6. technically, a solution can still be trivial even if the problem is difficult or complex. It is probably more correct to relate non-trivial to complicatedness. just say'n...
  7. Well there you go. that makes sense. the way I think about this is to imagine bending a batten. If you take a batten and bend it , it forms a fair curve. If you push that curve one side or the other, one side becomes more round, and the other becomes more straight. If you bend the batten more the distance between the two ends gets shorter.
  8. Depends on what the other settings are. Someone is trying to induce bend lower down the mast. Typically that results in a straighter mast from the spreaders upwards. Means a flatter main at the bottom but fuller mid and top sections. Also might result in less forestay tension as the mast compresses so your jib knuckles up. Where as tight D1's result in a more rigid lower section pushing the bend further up the mast. That means the mid/head of the main is likely to flatten more and the forestay remains tighter, so a flatter jib. I'd say, and I could be wrong, the 7 setting is
  9. This is another one of those "a good coach in a coach boat would probably see the problem in about 15mins" type problems. Let's assume the performance difference is real. And that when trimming both sails, exactly the same way on one tack over the other, and sailing the boat exactly the same way on both tacks, you get a bubble in the front of the main on one tack and not on the other. This means one of two things: 1) the pressure at the front of the main is higher on one tack than the other 2) the angle of attack of the main sail is different on one tack than the other
  10. I think that was my comment in the other thread. The first rule of instruments is they're probably wrong. The 2nd rule is...
  11. While this may be true, it is very much a guilty until proven innocent thing. Having "on the balance of probabilities" decided you haven't sailed the course, the onus then falls back on you to prove otherwise. Any PC would invariably face a level of bias against and/or under value any new evidence presented in a protest room. The first determination will have a greater bearing in their minds on the outcome. It's the same reason fake news sticks so well. It's hard for someone to make a new determination on something once they have already learned or decided on an existing one. Espec
  12. No it's a problem here too... Especially old boats on moorings, surveyed or not. Might be better now I don't know but after every storm here it seems like the insurance goes up as random mooring minder X washes up on a beach and takes a few more expensive boats with it.
  13. On a 24' 1T boat, I think the pros would have looked at the numbers and turned the instruments off by now. Fundamental rule of computational systems though, always compare what the computer is telling you against reality. Plenty of plane crashes (and the odd shipwreck) have happened because the pilots believed their instruments first and reality second.
  14. If your instruments are telling you you are 40% off and 10-20deg down, you need to stop doing that. Go back to basics and sail the boat. Get some other reference point; an analog compass, other competitors, hand held GPS. Without sog and cog numbers, I'm willing to bet you're sailing your boat into oblivion because your instruments are telling you to.
  15. ^^^^^This^^^^^ I mean real simple question from this, have you used an independent hand held GPS to measure SOG on both tacks? is the difference more pronounced when the boat is healing (upwind) vs not (downwind)? When you are sailing against other boats, do you get disproportionately smoked on starboard tack? 40% off is a lot. If that was real, you would certainly know about it as other boats whizzed past you. First rule of instrument based systems is they're probably wrong. Second rule of instrument based systems is... well you get the idea. IMHO People get too fixate
