I'm helping our local club develop a 'golf' handicap system (their terminology - not mine) where the skipper and boat have a handicap based on their performance amonst the fleet. This will only work at the club level.

Oh yeah, they sure do. I grew up sailing on leaners and I crew regularly on a Melges 24, and PHRF sucked then as much then as it does now. The best and worst thing about PHRF is the numbers are set regionaly which creates all kinds of problems. Makes for some interesting gossip and email threads though. Monohull sailors and multihull sailors IMHO are the same people with the same interests, it's just the platform we do it on is a little different. And yes, they have the same OD vs. PHRF (open) debate that we do.

Posts: 1,012 South Australia | For many years I sailed at a club that used a "back calculated " handicap system to ascertain, What they considered was the best way to judge the "best sailor" in a very mixed fleet (fleets of various cats as well as multiple mono hulls). They used this system over the duration of the racing season as well as for regattas of four or more races. The way it worked was that the first race was sailed and from the finishing times of all boats their "handicap" for the next race was calculated on the basis of the times needed individually for all the boats to have finished equal first (on handicap). This "handicap was then applied for the second race and the resulting positions counted for the overall regatta (the first race was used as the starting point and didn't count in the overall results). Similarly the same "back calculated" handicap system would then be applied for the resulting times of the second race ie their handicaps were adjusted as if they would all have finished "equal" at the finish (on handicap) and their "new" handicap would then be applied to the third race. This "handicapping would continue for the duration of the regatta/ season. Very accurate and fair comparisons between different boats, sailors, and sailing skills were obtained from this system and it is the only system that I have seen where there was never any argument between competitors about the final results being "unfairly" influenced by, conditions, quality of respective boats, difference in speed and/or performance of boat, weights, etc. It was a system that automatically took into account ALL the variations between different boats, speed, weights etc, and put every one on "a level playing field". At times different sailors tried to "rort" the system by "sand bagging" for one or more races to greatly improve their handicap, but in so doing they may have been able to win ONE race as a result but with their results from their "sand bagged" race/s and the considerable resulting handicap penalty resuling from their erraticly improved "winning" race, they always suffered appropriately. The best way to sail under this system was to always sail "to your best" for the first race , and then try to sail every following race with improvement ie sailing up to and better than your previous race's handicap (ie consistency). The calculations necesarry to incorporate this system were simple and the results were always available within approx' 30 minutes after the final boat crossed the finish line. It is a system that proved itself over a long period of time and required no measuring, no boat formulations, no class yardsticks etc, all a sailor had to do was to turn up with their boat and they knew that for any regatta or series at that club, they could race on an equal footing with ANY other class of boat and sailor. It just worked to perfection for fleet numbers from as little as 12 boats up to regattas with numbers into the hundreds. OD, one off's or even for a "bath tub" with sails made no difference, the system worked and worked well. This is the primary system used to calculate the "yardstick" for different classes of boats, the difference at this club was that they used it as an ongoing "living" handicap system that was continuously "updated" and didn't stagnate (like a yardstick can) for the entire season/s and unlike a yardstick, would not loose it relevence to the average sailors actually competing week in week out. | | | Re: How many really don't like one-design racing?

Posts: 44 | As I was reading this post I was wondering, is there some sort of reversed handicap used by anyone? By this I mean that the extra time added to each sailor because of handicap is given at the beginning of the race, and not the end.
Say theres a regatta thats X distance long, between an H16, a Tornado, and a Blade F16. The distance is caulculated before the race and instead of everyone starting at the same time, the H16 starts first. Then the Blade f16 start as soon as its horn is sounded when Y time has passed, then the Tornado after Z time has passed. That way you could have a first-to-finish race between these 3 said boats.
Im not very experieced here, sailed alot on a laser so didnt have the problems described here, but I think this might work to some extent. The main problem would be the hassle of finding all the numbers before the race, and you loose the pre-race battles between boats which I find to be very important. | | | Re: How many really don't like one-design racing?

Posts: 1,669 Melbourne, Australia | Hey scooby,
The tolerances allowed in the Tornado class are to allow for amature builders, other manufatures and varience between boats off different age. Even SMOD are never EXACTLY the same and I am sure they have tolerances too as it is not possible to make evey boat exactly the same.
I helped the ITA measurer set up and test measure before Athens and you will be suprised with how fine these tolerances are when you measure the boats.
Here is some interesting reading for you from the ITA web site. It explains some of the differences and advantages of one-design over one manufacture.
The Tornado was designed in the autumn of 1967 by Rodney March from England, with help from Terry Pierce, and Reg White, specifically for the purpose of being the new Olympic Catamaran, which was to be selected by the IYRU in an Olympic Catamaran Trials. The boat was developed mainly in Brightlingsea, England.
International Status was granted to the Tornado as a result of its outright winning of the IYRU Trials held in England. The next step, adding the Catamaran event to the Olympic program, occurred two years later, with the result that the first Catamaran event, sailed in 1976 in Canada, was sailed in the Tornado. The Tornado is an outstanding example of a class that was designed specifically for Olympic competition that has become a successful International class on its own merits.
The Tornado has since remained unchallenged as the ultimate one-design catamaran. With its modern, stylish rigging and sleek lines the Tornado is quick to catch the eye of any water-drawn on-looker as it speeds across harbors, lakes, and oceans in over 30 countries around the world. With its ability to reach speeds of 15-18 knots upwind and downwind, and 33+ knots reaching, the Tornado is truly the purists' speed machine.
CREW WEIGHT The one-design (as opposed to one-manufacturer) Class Rules have allowed the Tornado Class to insure close racing from sailing like-designs, but with the ability to alter the shape of the sails within the approved sailplan to control power. This has allowed teams to be competitive regardless of weight combination or stature, an important feature of the Tornado that has survived the years and the change to the new rig.
The problem often associated with one-manufacturer classes, where in addition to the boats the sails are also strictly controlled, is that a standard weight/height combination dominates. With the ability to alter the sail shape within the Tornado sailplan has resulted in a class where minimum crew weight is not necessary; in the final results in a Tornado event, it is common to have teams whose total weight varies by 40 kg to appear in the top 10.
MATERIALS Another advantage of the one-design concept with multiple manufactures is the freedom to allow competitors to build such things as rudders and boards, and to do their own rigging. This insures increased strength and extended competitive life of components as modern materials become available at lower cost. An example of this; from a one-manufacturer class rudder replacement can become costly if the materials chosen by the manufacturer years ago cannot be upgraded. Over the years, the Tornado class rules have changed to allow for material improvements in many of the details, especially sails, to take advantage of improvements.
Rigging also has high replacement cost. If a manufacturer chooses lower-grade materials to keep the "new purchase price" low in order to be competitive in the retail market place, it is the active competitor who pays extra by having to constantly replace the lower-grade components. A fine example of this is the traveler on modern catamarans; on the Tornado, modern technology has lead to a dramatic decrease in replacement costs, as parts can be mixed from a variety of sources.
LIFE EXPECTANCY The natural technological evolution of materials, plus the push for the sailors for stronger boats at the same weights, has allowed the Tornado Class to increase its competitive life dramatically since the late ‘80’s. While having a reputation as fragile and short-lived back in the 70's, the modern Tornados have racing lives of 7-10 years. Many of the world's Tornado sailors, who actively race in other catamarans, know well that the modern production boats have top-level racing lives of 1-3 years.
One of the major causes for the low resale value of the one-manufacturer boats is that they are often supplied at major events. This saves the competitor no money, since they have to have the boats to qualify to get to the top events. These supplied boats, which are then sold cheaply by the manufacturer after the event, actually hurt the most active racers by lowering the resale values of their won boats.
The rules of the Tornado class have also resulted in sails that have long racing lives, the result of the competition among sailmakers for quality and durability. One-manufacturer sails, on the other hand, are mass produced at the cheapest price that the manufacturer is willing to gamble with, from materials that are not the quality of open classes. The result again is that the racing competitor pays more, buying more sails to stay on top.
CLASS RULES The Tornado Class Rules have evolved and been developed over many years and now ensure strict attention to all details relating to the performance of the boat. Rules are modified as needed and wanted by the sailors themselves, to allow the Tornado to advance with modern technology yet always considering the long-term effectiveness of the changes.
The Olympic status of the Tornado has brought some of the finest sailors from all over the world to the class. With over 22 nations regularly attending the annual World and Continental championships, and with the medals won at the Olympics going to sailors from all the continents where the boat is active, the Tornado has a world-wide level of racing matched only by a very small handfull of other classes.
The Class Rules allow the boats to progress with technology and let modern materials such as carbon fiber, nomex, epoxy resins, and high-grade aluminum to be used as they fall in price and can be incorporated into the boat, resulting in constantly improving quality. This helps resale values and enables the Tornado to maintain its marque as the ultimate speed machine; to this day, closing in on 40 years after it birth, the Tornado is still the fastest one-design production boat in the world.
For the immediate future, the class is concerned with ways to bring in more modern, lighter materials while maintaining the one-design nature of the boat, and done in such a way that the purchase price of a new boat can be contained.
The Tornado: in its first Olympics, it was the fastest and most spectacular of the Olympic classes. Now, after the turn of the century, it is still that boat, the fastest, most exciting,most spectacular of the Olympic boats.

Posts: 9,582 North-West Europe | Like every promoter the T class lied about 33 knots speed of the tornado. The fastest time ON A REACH that was every recorded on a Tornado either during speed trails in England OR the Bacardi Blast at Bermuda (1997 world championship fun race on a rest day) was a striking 23,48 knots !. All measurements were taken over a 500 yard or 500 mtr distance. If you want you can see some MPEG footage of the event here : http://www.acay.com.au/~gonzo/tornado.mpegHere the commentator clearly inform us that the German crew won this fun event by taking 12.53 second to cover the distance at average speed of 27 LANDmiles/hour (otherwise he would have said knots). I'm sure those 33 knots (38 landmiles/hour) claim of the Tornado is just a typo that has now been repeated for ohhh 8 years now. You would expect that someone would take the time to correct this error. Don't believe much of what promotors say and research the matter. Often the claims a very easily disproved. By very careful when any class assures that their beach catamarans reaches past 25 knot or speeds up beyond 25 knots on ANY course. With the extensive use of GPS units we now know that beach cats don't perform past 20 knots in a consistant way. Meaning under their own power. Maybe in a few very special cases you surf of a large wave right at the best time and hits 15 - 30 knots for 1 or 2 seconds but that is it. Also all classes are extremely handy in building up their own superiority by double speak. Example : Tornado stays competitive as a platform for 6 a 7 years, of course (they say), all other stay that only some 3 years. This naturally leads to the "fact" that tornado's are cheaper to race, right ? Wrong ! The same tornado costs as good as TWICE as much to buy new than a good portion of all others. So in fact the end result may be that the two classes over a period of 6 years are about as expensive. And so on and so on. There are only two classes that I know off that don't venture into these shady area's and give it too you raw and exact. The rest well, lets just say that they have or feel a need to play themselfs up beyond realistic proportions. Wouter

Posts: 806 Toronto, Ontario | wouter, gps instantanious speed readings are not as accurate as you would think. And I don't think that a 500m average distance has anything to do with the instantanious speeds that the boats can achieve. So the truth is probably somewhere between 33knots and 25 knots. If you _really_ want to measure instantanious speed then you need a radar gun. We bought one for our regatta and anyone wishing to test their speed is welcome. Sandbanks Open Aug 6-7 2005.

I didn't use instantanious GPS speed readings.
>>And I don't think that a 500m average distance has anything to do with the instantanious speeds that the boats can achieve.
-1- you think or do you know ? -2- If I say that may cat attained 50 knots speed on a reach, what do you read into that ? Instantanious speed or sustained speed ? -3- A series of instantanious speed will lead to higher 500 mtr. speeds. It is also the official speed measuring way. -4- Bacaradi run used a stretch of 500 feet, taking a Tornado 12.53 seconds to cover. When does a measurement become instantanious speed ?
>>So the truth is probably somewhere between 33knots and 25 knots.
What is truth ? Please define truth in this respect.
What ever your answer to the above question, the claims made suggest something that ISN'T true, namely sustained speeds above 23 knots for more than 13 seconds.
>>If you _really_ want to measure instantanious speed then you need a radar gun.
I don't agree GPS units can be dependable. Set the unit to poll every sec or so and read out the track. Plot the travelled distance per read-out look for a segment that shows only very small swings in travelled distance over a few samples and calculated the average speed from that. Errors in GPS read-out show themselfs as large swings in travelled distance from sample to sample. Engineers and educated persons will recognize this as the statistical defined DEVIATION. Look for a data series with a small deviation component.
Besides who said that a radar gun is accurate ? I know how that works and it you point that thing at the mast and it swings forward you get the same offsets as GPS unit can have.
>>We bought one for our regatta and anyone wishing to test their speed is welcome.
Sounds like a good test. I'll be glad to hear the results.

Posts: 465 FL | It is hard for me to fathom a T over 28 kn in 40kn of wind. The highest speed I have known the Tornado to go was at CORK '75. A 40kn storm hit, when the the fleet got to the reaching leg. The peak of the storm must have hit, when the leaders got to the jibe mark. At this mark a couple boats broke their side stays, one of them was Reg White who released the other stays, so as not to damage the boat from the mast. Notary was there on "Salt Water Wine", Zutec on "Twister" & Smyth. Anyway a Canadian destroyer radared the fleet at 28kn average. That's 33mph average, at that speed the boat was no longer in the water it went like a skipping stone from crest to crest 9'(3m). It was amazing the Tornado could skip the crest, and soar over the trough. It was sheer madness, with some poet license here, it seemed like we zoomed over 5 crests in ten seconds, and the wind would calm down to 2 or 3 crests in 10 seconds a la bucking bronco, and then accelerate again. I will never forget the thrill, not to mention wondering will the wind ever slow up. I recall a Tornado to windward of us, and counting it cartwheeling/rotating about it's mast 3 1/2 times, and the crew later righted the boat, unassisted? Anyway, I would call it somewhere between sailing/flying & holy ____. Great wind & waves, Chris | | |
