    Illegal C420 at Nationals

    What do you mean? These are the international 420 class rules and construction plans just as a reference. Has nothing to do with the american class, except the boat looks the same.

    Here links to the Int420 building specs. Coremat or similar is allowed, also there is an area specified where coremat must be used. Biax and UD is not allowed. Minimum is 800g/m2 of glass. https://www.sailing.org/tools/documents/4202009CRC120209-[6949].pdf Class rules: https://www.sailing.org/28296.php Don' know if this does help....

    Do you have a copy of the builders manual? I have been looking at the class rules, but this "compare to randomly selected other boats" stuff I can't understand nor measure. (if I "randomly" select other PS2000 the boat measurers, next regatta I "randomly select" boats of other builders, and my boat does not measure? How does this work?)

    You could do Lamboley testing for checking weight distribution. You can check panel stiffness. You can check the boat for global torsional stiffness. You can check laminate samples for glass content. I think these would be the most important things affecting speed. I don't know what the problem with the Solos is. In EP foam sandwich you can build panels that are a lot stiffer and lighter than Plywood, so you can concentrate the weight around the daggercase. These boats would go much easier trough waves. If you look at Contenders you can still see a lot of good sailers using wooden boats.

    Generally a measurer can only check the boats in regard to complience with the current rules. It is the class that makes the rules. And it is normally up to the class to modify the rules and allow boats that are out of spec, or just ban the boats. In many classes this could be done via ballot, but I don`t know how the Club420 was set up. That a boat does not measure does not automatically mean that it is any faster. Laser class rules specifie that your traveller rope must be one single line. If you cut the line and tie it back together it is out of spec, while this does not make the boat go any faster. They also specified that you may only use manufacturer supplied blocks for the vang. An aftermarket block may cost half of the manufacturer supplied one, and has absolutely no effect on boat speed, but the boat does not measure anymore. ( While things that do have an effect on speed like mast rake and weight are not measured ?!) Without knowing the text of the construction manual nobody can say what the problems are. As Gouvernail said just the use of out of spec materials does not automatically make any boat go faster. As I pointed out a change of the process from handlayup to infusion does not automatically make a stiffer boat. If there is no performance gain, I think it is unfair against people like you to ban the boats. The manufacturer maybe should lose the license to build class legal boats as a consequence, and maybe the class should go back to the old measurement system, where each single boat must get measured before it get´s a plaque (I think the class has a system like the Lasers, so boats don´t get measured, but the manufacturer promises to build according to the construction manual? Please correct me if I´ve got this wrong.) Then these boats propably would not have been sold as class legal ones. One could say that the class failed to perform proper control of ensuring onedesign by not measuring the boats before they were sold to the end customer (just my private view) Maybe the class should look for independent advice from a competent yacht designer, who could perform tests and calculations in order to check for performance advantages of these boats.
  6. If I've got it right there was a paper from LPE, where they are saying that they are moving production to Portugal due to Brexit, but they also have an chinese factory that is serving asian markets. Then they said that LPE stops to exist in september 2019. That was also the reason why they wanted ILCA to sign a new trademark agreement on using the name Laser for running Regattas. No idea what all of this means.
  7. Yes there are some nice words printed on very nice and clean white paper. I think Gouv and I are talking more about the ugly, stinking and shrinking reality of boatbuilding. But Optis have shown us that it can be done, so it should be possible to insure onedesign.
  8. The Laser class rules are indeed very special. Does an old boat with numbers of 65000 measure against 5 of 200000? Does one current LPA measure against 5 current LPE? Is this kind of measurement regulary performed on championships? Just asking, I don't know how this works. How much does the shape of the hulls diverge? Are all molds made from a single plug that was made in the beginning of the class? Did manufacturers build new plugs? Are they all the same? Worldwide? Do templates exist, to measure new molds or plugs? Today some low shrinkage tooling systems exist, but that was not the case before +- 1995. How can new builders produce molds or hulls that measure? Is 3d CAD data to mill plugs availible?

    Seggerling Plans

    Yes all nice boats. With a length of 4,7m the Seggerling seems to be the biggest one of all boats mentioned, and is propably the one for the older and heavier generation that are looking for a light boat. Phantom seems to be the closest, very nice boat, but I could not find much info on DIY building.
  10. Interesting that JL feels he is bound to the democratic decisions of EURILCA ( even if he personally would have voted against something ), but he is not bound to democratic decisions of ILCA WC, even if he voted "yes" on a particular vote, but now has changed his mind. I believe that the competitors of the current Worlds in Japan have a strong position in their home countries, and should use their degree of popularity to inform in their countries and languages about what is going on.

    Seggerling Plans

    Yes there are many nice old small national classes out there. I don't have anything to do with the class or the designer, never sailed a Seggerling. What makes the boat interesting I think is the special, very simple and fast building method, and a hull shape that looks similar to the most modern designs like Aero, Dzero etc.
  12. situation in Argentina: https://www.sailingscuttlebutt.com/2014/04/13/laser-class-distracted-drama/ Laser class distracted by drama Published on April 13th, 2014 While the Laser class remains a staple in the one design spectrum, there are troubles in paradise. When a one design class is fully reliant on a single supplier, and when the flow in the supply line gets clogged, a class can choke. While the class strives to remain viable amid the effects of an on-going legal battle between the Laser commercial parties, a solution in Argentina has been to take matters in their own hands. “For the last few years, a boat builder has been selling a very popular dinghy sailboat, which is commonly known as the 99% Laser,” notes Ari Barshi of the Laser Training Center in Cabarete, Dominican Republic. “It has all the Laser ingredients, races with the Laser, but does not display the Laser logo or name. The Argentinean program is a success as the boats are cheaper and parts are easily available.” And now there is talk of this Laser copy extending beyond Argentina. “The boat will be called the 99er and the domain name 99erclass.org has been registered,” explained Barshi. This won’t occur without a battle, likely from ISAF and the International Laser Class Association (ILCA), but most definitely from those that claim ownership rights to the Laser. Barshi believes the law is on their side. “The Vessel Hull Design Protection Act is valid for 10 years, and when this time expires, the boat design is in the public domain,” states Barshi. “We have also never heard about a case in which builder Laser Performance, Laser designer Bruce Kirby, or any other enterprise ever trying to prevent anyone from building Laser clones based on design right claims.” Barshi has plans to start building the 99er in the Dominican Republic. For questions, he can be contacted
  13. even worse: Laser 2000 fits into RS 2000 class.....
  14. Yes. Like F18. This class was founded by the french sailing federation to include existing boats by KL, Mattia, Valer, Nacra. Dart, Hobie and others followed. New Builders like Diam, Mystere, Capricorn and Cirrus designed new boats that fit into that rule. Nacra infusion, Hobie Wildcat and Hobie Tiger are also international classes on their own, that fit into F18

    Seggerling Plans

    Hi, I used google to translate these infos, and tried to correct the worst translation errors ( a Baum (boom) translates to tree... some more stuff that makes absolutely no sense... try for yourself, the original google translation sounds funny, at least to me..) SEGGERLING delights both beginners and racing fanatics. This design was created at the request of experienced regatta sailors of the international Moth class and other single-handed racing dinghies. On the one hand the desired boat had to surpass the high technical level, the rapid speed and the enormous price-worthiness of the Moth due to its own construction - on the other hand the new dinghy should outperform the other one-hand classes above all in terms of safety, comfort and seaworthiness. This makes the SEGGERLING ideal for the experienced dinghy racer who want to meet for fair racing without hectic or acrobatic, or for successful yacht skippers who still want to sharpen their sensitivity at the helm by modern one-handed sailing. In addition, everyone admires the sleek lines and the natural beauty of the wood. SEGGERLING is exceptionally safe, fast and comfortable: the safety is created by the chined hull shape, which is also advantageous for DIY. It effectively creates a supporting kink, which creates enormous floating stability due to the large width in the waterline. The sails and the boom length are relatively small, so that even at 6 Bft. you can gybe safely. With a lot of wind, the SEGGERLING can be kept upright easily due to the large boat width. Safety against sinking provide three separate buoyancy chambers and the building material wood. All these safety measures give confidence! SEGGERLING is fast. The high speed results from the lightweight plywood / epoxy construction, from the state-of-the-art rig, the sharp floating lines for doldrums and the wide transom with for strong wind planing. The concentration of all weights in the middle of the cockpit and the bow, which cuts softly through the waves, ensure balanced ship movements even in rough water. This increases the speed and does not cause seasickness. The convenience comes from the pleasant boat width, the "conflict-free" boom height, the flat seat on the daggerboardcase, the wide cockpit and easy handling. So this purebred racing boat brings true pleasure even when cruising! SEGGERLING can be easily built even by laymen according to the detailed drawings. Actually, you can do with normal hand tools, but jigsaw and drill save a lot of sweat. By working on the modern Segger system you save the costs and time for building a mold, frames, etc. This design guarantees that non-professionals with little effort and without special knowledge easily produce a good boat and thus often more than 50% of the shipyard price can saved. In addition, we are always happy with advice at your disposal. Easier, cheaper, faster! If you are interested in buying a new boat, but you don´t want to build yourself you can contact Hein boatyard: http://www.hein-bootswerft.de/index.html ( run by Max Billerbeck, top contender sailer, current Swiss champion ). They build the hull in grp with wooden deck. Sails you can get at Clown Sails Hamburg https://www.clownsails.de/segel-und-mehr/seggerling/
