    Thanks, worth a try. 

    I hoped that RaceQs tracking function would be able to do the trick. Since several people in the club use it to compare our sailing after the local races. But I can't get the correct data into into the system. 

    I expect the limitation with RaceQs is that it will only use its estimate of true wind direction, you have a limited ability to adjust. And it doesn't figure wind speed at all. 

    Still, pretty useful for comparing boat vs boat. 

  2. Olympics should be about accessibility (which means affordability) and competitor ability (which includes both athleticism & smarts), not about the pinnacle of technology (we've got AC for that). Viewer- and/or TV-friendly helps although I don't know that sailing is ever going to crack prime time. 

    J70, Melges 24, FarEast maybe. Anyway, reasonably modern planing keelboat with asym kite. Crew of 4 with genders evenly split & a total crew weight limit (which probably means the girls drive & do bow, & if they did it right you could probably put at least one Finn guy in the middle).

    Match racing on W/L courses - lots of close, exciting racing & umpire-friendly. 

    If an Olympic host can't hire a few mobile cranes for a couple of weeks they don't belong in the Olympic business.

    Ace Hardware is still stocking DeNat in the paint section in Maryland.

    Yeah, I think that's true in most of the free states. Just not California because we're going to save the planet by ourselves...

    Pretty sure I saw some at West Marine the other day.

    I think it can still be sold as stove fuel, but you won't find it in the paint section any more. 'Cause planet, you know... 

  5. Sounds like the USNA experiment was done with shock loading - "several crew being hurled against the lifelines." 

    They also noted that the leg of the stern pulpit was vertical, at a right angle to the deck where the bow pulpit was angled and survived better.

    You have a link/copy to the study? I can imagine that would be true with new dyneema in a test lab environment.  But we know it is NOT true out actually on boats racing in the real world.

    Don't have a link to the actual study but below links to a Practical Sailor article. 

    Granted a bit dated (2012) and may be unique to stern pulpit designs similar to the Navy 44. But their finding was that the solid structures failed significantly below the breaking strength of 1x19 wire. 

    I don't know but would suspect that real world failures are mostly as found in the study or a result of compromised swage fittings. Are there any cases of wire lifelines parting in the middle of a span?

  7. Regarding strength, there was a study done by the Naval Academy that found that when a lifeline system failed it was pretty much always the pulpits that gave up first. I suspect this would be true even with less-than-perfect dyneema splices or lashings (assuming no chafe, which I know is a big assumption but is at least readily inspectable). 

  8. US Sailing SERs require uncoated stainless for Ocean or Coastal races but are silent on Nearshore. And of course cruisers can do whatever they want. 

    Splicing dyneema is simple enough that you can just build the lifelines on the boat to make sure you get the length right. Do the first eye splice, attach one end, string through stanchions & then measure out where the other eye should be. Expect some construction creep as the splices work themselves in so a little short is better than a little long - you can always snug up the lashing.

    I luggage tagged one end and used a lashing on the other. Better to luggage tag around the the pulpit tubing rather than the steel loop provided for attaching wire lifelines so the bend radius in the dyneema luggage tag is larger. And use a thimble in the lashing end for the same reason.

    I've ruled alcohol out. Only options at this point seems LPG or electric. 

    Why? I've got a two-burner Origo unpressurized alcohol stove and I love it. The system they use (a cannister with a wicking material in it) is very safe and not spilly at all. They make versions with ovens that use the same cannister system.

    And fuel is relatively cheap (although due to California air regulations getting a little harder to find round here).

  10. New ERS also includes a definition of CONNECT:

    CONNECT: To bring together or into contact so that a real link is established by which one item effects the function of the other; therefore includes “attached to” and “sheeted to” the corner of the sail.

    So my reading of 55.3(a) would be that it is allowed to sheet a headsail to a whisker pole. And I don't see anything that disallows the pole being to leeward. I'm not sure old rule 50.3(c) prohibited that either.

  11. I agree, keep whiteboard time in the first session to a minimum. Getting out into the yard with a rigged 420 on a dolly is more important than explaining Bernoulli. You can teach parts of the boat, terminology (port, starboard, etc.), wind direction, points of sail and sail trim in that setting probably more effectively than in the classroom.

    Might emphasize "when in doubt, let it out." Ease sheets until the sail starts to luff, then trim in until they just stop. I expect most beginners tend to overtrim.

    One of the first things my dad taught me was if things start to go pear-shaped, push everything (tiller, sheets) away from you.

    A few uninformed opinions here... so typical SA.

    The RC for this club is a rotating assignment, every boat has to sit out one race and do RC duty. Positive is that the burden is shared, negative is that no one is particularly experienced and some teams give the RC duty more or less attention. 

    Gotta say though, not sure that the OP posting the email to this site has much business complaining about tone.

    Well that changes the dynamic a bit I think. If every boat eventually has RC duty and one boat gaffed it off when it was their turn, it seems reasonable to call them out in front of the fleet. But I think I'd still have used more moderate language (drop last sentence) unless that boat was a repeat offender.

    Edited to add - if all or most boats screw up when it's their turn to do RC then maybe look inward - perhaps your process isn't as simple as you think it is and needs refinement or training.

    are you sure about that? (I'm not saying you aren't)

    The Equipment Rules of Sailing do not have the word "connected" in them anywhere. "Attached" appears 35 times, but why would "attaching" the clew of a headsail be any different than "attaching" the clew of a spinnaker to a spin pole?

    It's infuriating when these documents don't link the way they are written. 

    One of the changes made in the 2021-2024 ERS was changing most instances of "attach" to "connect".

    I'm sure this isn't just a "happy to glad" change, I have to imagine they had a darn good reason. But I don't know what it is...

    Quite right SailRacer.

    RRS 26.1 states VERY clearly "Times shall be taken from the visual signals; the absence of a sound signal shall be disregarded."

    If the sound signal is a bit off it is inconvenient or annoying but nothing more according to the rule.

    His point "4.  The raising and lowering of the flags is supposed to be synchronized with each horn"  is back to front. Shouldn't the 'commodore' have a better understanding of the rules?

    If he is that unhappy he should do the job himself.

     A volunteer will feel bad enough if they get it wrong without a public roasting which as @TJSoCal so correctly says above is completely wrong. 

    Yes it's the flags and not the sounds. But it sounds like in this event the sound signals are automated so if the flags are out of sync with the horns it's likely the flags are mistimed. And if competitors are running their own start timers it's frustrating when either the sound or visual signals aren't correctly timed. 

    It does sound like the RC needs to take a round turn. It's just not proper to scold them publicly.

  15. I was always taught "praise in public, chastise in private". Especially important with volunteers I think. 

    It's not unreasonable for competitors to complain about poor show by the RC. But there's probably a better way to deal with it, especially if this was a one-off and not a chronic problem. 

    If the club thinks an incompetent volunteer RC is bad wait til they try running their races with no volunteers.

    Pray tell, what is the fundamental difference? I have put the corresponding RRS rule and definitions for reference

     

    The differences aren't in COLREGS rule 12. They're in:

    Rule 8, requiring early and substantial action by the give-way vessel to pass at a safe distance (so for example a slight bear-away to pass inches astern of a starboard tacker is illegal under COLREGS. And a close cross on port is right out.)

    Rule 13, Overtaking. COLREGS allocate give-way and stand-on based on relative motion, RRS gives ROW based on relative position (clear astern, overlapped, clear ahead)

    Rules 16 & 17, Actions by Give-way and Stand-on Vessels. COLREGS assign both vessels responsibilities and neither vessel rights (note that the phrase "right of way" does not appear in the International COLREGS). COLREGS does not allow for luffing or other tactical maneuvers by the stand-on vessel, she's required to keep her course and speed as long as risk of collision exists.

    Only refers to a Two-Turns Penalty.  Failure to do any turns is a breach that can be protested.

    Don't think so. 44.1 says a boat may take a Two-Turns or One-Turn Penalty when she may have broken a rule. "May" is not "shall" and includes "or may not".

    Would OP or anyone have felt better if B347 had taken his turns and gone on to win the race?

    But a port - starboard incident is pretty simple and, if broken, a penalty turn/s is required.

    Not quite. Penalty turns are an option but a protested boat is still entitled to due process (at risk of harsher penalty). Recognizing that this incident didn't take place in the US, there is a US Sailing appeal (46) that clarifies that failure to take an alternative penalty when it's available does not break a rule.

    In this case it appears that the offender was protested, elected not to do penalty turns, elected not to accept a post-race penalty through arbitration (or maybe they were willing to but the protestor would not agree to withdraw), lost the protest in a hearing and was penalized in accordance with the SI by being assessed a 30% scoring penalty in the race where the incident occurred. 

    So is the argument that the penalty is insufficient ("not a penalty") because it didn't impact their regatta score?

    the arbitration system is an unnecessary complication as is SI's that alter what is already a rule which requires careful reading by judges, never mind competitors. Arbitration is not really there, I believe, for the benefit of the sailor but the smoothing of the protest situation to reduce the amount of lost drinking time by judges or the non delay of a prizegiving (maybe someone from WS can correct me on that)

    Well Appendix T arbitration only comes in if the NOR or SIs put it in, and even then the competitors aren't bound by it and can still go to the room if either of them chooses to. The purpose is stated in the preamble, to "eliminate the need for some protest hearings" (which I thing some sailors want) and to "speed up the process for events in which many protests are expected" (also a good thing, if arbitration is done properly). 

    But personally I'm less of a fan of arbitration for informal club events as it does add complication and I think many arbitrators don't really know how to do it properly. I like US Sailing prescription V2 better, which allows competitors to discuss it between themselves after the race and decide to take a voluntary post-race penalty. That can dispose of a protest without having to designate an arbitrator but still doesn't deprive anyone of their right to a hearing if they want one.

    Outside the US I suppose you could use the same language in an SI.
