  1. No... she is allowed room to round or pass the mark as necessary. There is a difference, and difference lies in the definition of mark room, in providing room to sail to the mark if your proper course is to sail close to it.
  2. It is a shared assumption that there was an overlap at the 3 length circle. so let's call it a fact. The overlap was established by W from clear astern. Explain to me why the reason for W bearing away or L holding course matters in the context of the rules? one incident, two incidents, it's basically the same incident. The two boats are so close together they are unable to safely maneuver without collision.
  3. No, she doesn't. because at that stage she's not anywhere near the mark. (that is, 1.5 to 2 boat lengths to leeward) If W is concerned about hitting the mark at that distance, something's wrong. Also, L doesn't have to predict what W might do leading up to the mark that may otherwise limit W's ability to round the mark. At that stage, the only obligation on L it would seem ( and starting to be a consensus) is giving W room to tack to round the mark. Why? because L is right of way, and W's not sailing to the mark as per the case book interpretation of the definition.
  4. Sorry, back to this point. L had right of way. What room was L supposed to provide W in this situation that she wasn't already giving?
  5. How should she have sailed? maintaining your heading in a "pressure knock" is a perfectly valid way to sail a boat. Most people don't though, they bear away, ala the incident in question.
  6. The two boats sailed into a lull. W bore away, L was moving forward on momentum alone.
  7. I mean, if it's not clear, I've read this to death so... I'm not sure what you're suggesting. But this is worthy of noting: Rule 18 no longer applies between boats when mark-room has been given. And back to the definition, mark room is room to sail to the mark when the proper course is to sail close to it. again, if your proper course is not to sail close to the mark, then you're not entitled to such room. There for, at that point, mark room has been given untill W proceeds to tack to lay the mark, and up until she passes head to wind, at which point it ceases to apply again.
  8. No... very explicitly, mark room is: Mark-Room Room for a boat to leave a mark on the required side. Also, (a) room to sail to the mark when her proper course is to sail close to it, and (b) room to round or pass the mark as necessary to sail the course without touching the mark. However, mark-room for a boat does not include room to tack unless she is overlapped inside and to windward of the boat required to give mark-room and she would be fetching the mark after her tack. In short, if your proper course is not to sail "close to the mark" you are not entitled to room and must other
  9. And yes, pics will come when I get a chance to mock it up
  10. Ok, So I have an interesting one (well I thought it was interesting) that goes like this: W and L are on a beat to windward, on starboard, in variable to light winds and smooth water. They are sailing close to the starboard lay line for a starboard mark rounding. W establishes an overlap to windward but inside L as they enter the zone. W requests room and L complies. A momentary change of pressure and direction hits W & L. W bears away, and L holds their course. The boats (ostensibly) collide. they are approximately 1.5 boat lengths from the port layline, and appro
  11. It's a boiler plate privacy statement to cover their arse. Ever read the privacy statements of any web app you use these days? "We collect stuff for a variety of reasons to 'serve you'. Some of it might be private and personal. We'll take all care but no responsibility" I'm not sure if it really absolves them legally but it is fairly standard stuff these days.
  12. I think you have some of the right concepts, but for the wrong reasons here. Especially in 3. Also, Angle of attack usually is something you talk about with regards to your sails and sail plan, so not sure what you mean by Angle of attack here... 2) Don't "feel", actually go measure. Find out where their mast base is, and where their mast tip is compared to known reference points. Use a tape measure. Most popular classes will have tunning guides around that give a reasonable first cut at this. Depending on how the mast is chocked at deck level, moving the mast heal forward can do l
  13. Raking the mast back does three things: 1) changes the CE as discussed above 2) lengthens the cord length of the sail plan 3) in doing 2, it changes the distribution of depth in the sail plan, effectively flattening it and reducing the angle of attack Beyond balance issues, nominally you rake a mast back to depower a rig by flattening the overall sail plan and on some boats (where rake can be extreme), lower the CE (marginally). It can make you point higher because of additional feel on the rudder and in theory, a slightly flatter, reduced angle of attack on the overal
  14. Dunning Kruger effect. They don't know what they don't know. My experience is there's often a bunch near the top of the fleet that act like they are the top of the fleet as well. Doesn't matter what the skill or discipline is, the difference between good, great, and exceptional is the ability to find those small things that make a big difference. The magic sauce if you like. For my part, a good program will apply best practice to achieve most of, if not nearly all the things in the long tail. A great program has done all the things in the long tail and knows how to fin
  15. Well actually, a barber hauler and a hobble are different. A hobble limits the maximum you can sheet the sail out and (one way or another) takes the load off it at the tail. A barber hauler pulls the sheet in or out but doesn't take the load off the sheet.
  16. Righto... so I get to the top mark 1) "Hangon, just gotta run this outside sheet" 2) "Cool, let me ease that too you" 3) "Made. Now let me re run this sheet to the new lead" 4) "ok done, take it up on the winch now?" 5) "we're good, disconnect the outside sheet again!" 6) "Set, now I can get back up on the rail" as opposed to 1) "Is the hobble connected?" 2) "Yep" 3) *flick* Effectively what you are describing with a fixed (cleated), outside temporary sheet is a hobble... The setup with the self gyber means you don't have to dick around with re lead
  17. It makes sense. I can imagine the need to slow the intake velocity so the cow can breath. Concorde has those magic boxes with the adjustable flaps as well
  18. I suspect the flow around the cow will be much more laminar once the cow slows to sub-sonic. At the speeds described, the cow needs a little prodder out the front to ensure the shock wave clears the rest of the carcass
  19. Last time I checked, yachts don't have mach number issues at the tip. Or maybe they do. I do need an excuse for a instrument wand on my masthead. Discuss Edit: here we go, I've found Sailor Al's gap... https://link.springer.com/article/10.1007/BF03186440
  20. ... Conformal mapping here we come.
  21. Long enough to know you haven’t thought this through properly or actually ever done it on a 40’er I’m intrigued to know how you are going to transfer a sheet with possibly a couple hundred kg’s of load on it or from a winch and a cleat. I don’t know about you, but I like having fingers and again, it doesn’t solve the OP’s problem of freeing up a winch
  22. which would consume 2 winches through a manoeuvre rather than freeing one as intendid?
  23. Probably about time we put a gybe in here before we end up on the bricks...
