      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 Australian Multihull Championships

    If anyone is interested, here is the text of some correspondence I had with the Texel committee a couple of years ago. I was particularly interested in their views about how well OMR catered for big/small, new design/old designs racing together. Here's what was said: From: nico boon [mailto:nicoboon1926@gmail.com] Sent: Wednesday, 18 March 2015 5:21 AM To: Alan Brand Cc: edith langens; geert ruesink; pentcho bodegom; renzo van der plas; zieger driezen; Maarten Bakker; arno molenaar; garym; klaas parrel Subject: Re: Question about Texel Rating Formula Dear Alan, Your interesting reaction requires more than a short answer. Your email and my answer I pass on to our members of the RC (rating committee) and some others to inform them. From the start of the handicap system it was clear that any system will not do for a very wide range of designs. A Hobie 14 cannot race well on handicap against, say the modern Olympic Nacra17 design. The same is the case when you compare the performance of a light, but relatively small trimaran like you mention and a heavier much longer catamaran. A lot then depends on the weather system too. With strong winds and heavy waves, the bigger boat will have an advantage. In Holland on partly inland waters with less waves, the lighter trimarans actually show more advantages. Both boats being well sailed. Neither a yardstick system nor a rating rule based on measurements will change these facts. We always explain people that the only way to find real winners is to let them sail one designs yachts, big or small. They do now, with the big round the world racers. Any rating is not only called handicapping, but they are a handicap too. Then, more developed designs generally perform better with the same length, sail area and weight. Especially better hull forms as well as more developed rigs made modern boats more competitive. Then these modern designs attract the better crews too. All these aspects are illustrated best by analyzing results of races like the round Texel with hundreds of cats. This I do each year. Even in a most popular class, the formula 18 designs, the spread in the results is very high. The last one in a group of 63 boats in 2012 takes 53.7 % more time to complete the race. It pleases me to include the analysis of that race in 2012 The remarkable fact is that graphs of the sailed times or corrected times quite well look like a straight line. For that purpose the winner in each (one design) class is given an index nr. of 100.0 to compare with all other finishers. That the rating formula works well is demonstrated by the fact that the graph of the overall list, with all 210 boats sorted on corrected times according to their individual rating numbers produces the most horizontal line, with the lowest factor a in the straight line formula. ((0.22). These elements atoned me with the limits of any rating system. But I still prefer handicap sailing because one design racing I find boring to look at. Variety in boats is more pleasant to observe. I hope you find the race analysis as interesting as I do. For bigger boats such an analysis is hardly practical for the number of boats of each class generally is too small for conclusions. My best wishes Nico 2015-03-17 5:02 GMT+01:00 Alan Brand <ajbrand@optusnet.com.au>:

    I suspect the issue of whether or not we can attract serious racers to our events has little to do with OMR but more to do with the vagaries and challenges/frustrations of the pittwater wind patterns. Something Tony Considine knows all about!
  3. 2017 Australian Multihull Championships

    Hi Tony, I'm not questioning why people want to race, we do it here every week and if I'm not mistaken we may be the only multihull club in the country that has a regular (weekly) race program right throughout the year. All I am saying is the majority of our sailors are perfectly happy with what we do and don't feel the need to race under a rating system. In fact we did run OMR each week in parallel with PHS a few years ago, and rather than being a positive thing it became rather divisive as the same boat seemed to win under OMR each week. One might hope this would encourage other racers to look to "optimise" or improve or whatever the appropriate term is, but it actually had the opposite effect with some people mumbling behind their hands questioning the legitimacy of the ratings in general or one or two boats in particular, thereby becoming divisive rather than inclusive and instructive, removing a lot of the pleasure we enjoy of just being out on the water which is really the point I was trying to make in my earlier post. I personally have no objection to OMR as a concept but I do have some issues of detail with it (as do many others). At the end of the day it's fine for championships but it isn't the be all and end all of enjoying getting out on the water and racing around the cans. As I said above, this is what we do here each week. My personal opinion is that once the focus and pre-occupation becomes all about getting the "number" as low as possible so you can optimise your chances of winning, a lot of the fun and enjoyment of sailing gets lost. Regards Alan

    Hmmm, I wonder where "go out and enjoy your sailing young/old man" fits into all this? Call me old fashioned, behind the times, silly old fart, whatever, but I can tell you hardly anyone here at RMYC Pittwater gives a rat's arse about OMR because the primary motivation each week is to enjoy a sail around the Pittwater puddle, sink a few ales back at the club, collect (or not) a PHS winner's bottle of vino, relive the race through individual post-mortems or "if onlys", then go home happy - having enjoyed a nice day out on the water and a few beers with mates, ready to do it all again next week. So endeth the lesson! Cheers Alan

    I wonder what a "Mulithull Championship" is? Is that a Queensland thing? http://results.rqys.com.au/amc2017/series.htm
  6. Lock Crowther Multihull Regatta

    Nice one Stephen. Thanks. And what added to the magic of this year's regatta was Beryl Crowther, Lock's wife, our very special guest, sailing on Saturday on Te Arawa, a 42 year old Crowther Spindrift 45' cat in 30 knots! Cheers Alan
  7. Lock Crowther Multihull Regatta

  8. 2017 Australian Multihull Championships

    Yep we southerners did point out at the time the proposed clash with the Crowther which will be hosted by RMYC Pittwater for the 22nd consecutive year over the October long weekend as has always been the tradition. Special guests at the celebration prizegiving dinner as always are members of Lock's family. We shall enjoy. Cheers Alan
  9. Lock Crowther Multihull Regatta

    Yes regarded by many as Australia's friendliest, laid back regatta. Entries now rolling in. Click the link here to find out more and lodge your entry. Hope to see you there. http://www.royalmotor.com.au/multihulls/Crowther.html Cheers Alan
  10. Australian 8.5 "box boat"

    One of these called "Box Office" sailed in the 2013 Lock Crowther Regatta on Pittwater. OMR rating 1.029 http://www.royalmotor.com.au/multihulls/results/2013/LCMR/series.htm Some more info here. https://www.tradeboats.com.au/tradeaboat-reviews/boats/1408/box-boat-85-od-review
  11. Tacking Angles

    Software I'm using is a phone app called RaceQs. AFAIK, it's using a GPS track to compute tacking angles.
  12. Tacking Angles

    Graham, Saturday course was to Juno Point in a reasonable NE breeze at around 040. Four tacks upwind in Pittwater in reasonably flat conditions to get up to the river averaging about 110 angle. Closer to 124 upwind coming out of the river. Hopefully will get some comparative data from others to contemplate. Just curious to know what is reasonable to expect.
  13. Tacking Angles

    Wondering what data is around on typical upwind tacking angles for our boats? On my last few races in 12-15kts, on my Corsair Dash 750, I'm struggling to do better than around 115 degrees...a long way above the magical 90 or better! Admittedly, last Saturday had us working into an incoming tide with 1-1.5m waves at 15kts true which seems to affect pointing ability on a 24' boat much more so than my competitors at 30' or more. Curious to know what others are finding in different conditions? Type of boat, light vs heavy conditions, flat water vs waves etc? Thanks Alan
  14. Pete, if I can be persuaded to run it again, Crowther Regatta on Pittwater will be Friday September 29 to Sunday October 1 2017. Cheers Alan
  15. Well good luck with that. Knowing the difference in course lengths between div 1 and div 2 and if Monday, Tuesday and Thursday's forecasts hold true, I'm prepared to wager now this will be another "big boat" regatta. OMR was never designed for single fleets of widely varying performance and capability in different wind and wave conditions. It's not that smart and was never designed to be. Howl me down if you want but if you doubt what I'm saying read up on the Texel history. On the other hand and if the conditions are light, it will be a great shame if many div 2 boats score DNF on the longer courses. Ok it wasn't light and it wasn't a "big boat" regatta. Starting div1 & 2 together and sailing the same course worked out really well. When i get time i will work out the combined results for each race but race 6 shows for sure that the latest revision of OMR is working really well for the Wangi 2016 fleet. Race 6 OMR combined: 1 Wilparina III 2 S'Knot 3 Trinity 4 Triple A 5 Airplay 6 Fifty Fifty 7 Bare Essentials 8 Foxy 9 Tiger 10 SPC4 11 desert first 12 Mad Hatter 13 Jaguar Please check Golgfinger. Without having the benefit of combined Div 1 and Div 2 results for the series, the facts are this for anyone who wants to do the sums. On average over 6 races the Div 1 boats sailed the course about 20% faster than the Div 2 boats. Hardly surprising. So if OMR is reflecting reality, for "mixed" fleets sailing the same courses, I would expect roughly the same differences in OMRs. However, even though the Div 1 boats were typically 20% faster, on average, for this regatta, their OMR ratings were only about 13% higher. Sure, sure, averages are averages and while it is true that a few Div 2 boats sailed extremely well to their rating and were deservedly the podium finishers in Div2, the reality is that the majority of the Div 2 boats could not match it with Div 1 boats either on rating or speed. Most races were sailed in breezes around or above 20 knots.
