Our mission

Nicky Arnoldus from Canada

Welcome on this website for lovers of International 12foot dinghies. Eco friendly, so just wood. The design of this boat was made by Georg Cockshott in 1913. Our mission is to keep the boat worldwide as original as possible. No expensive modernisation and also no fiberglass.
Every year we organize at least four Friendship regattas, where we met each other, sail together in a friendly atmosphere.
We don't have a formal organisation with official roles, although a commodore is in charge, we are just a club of volunteers. If you are new, you will find here URL's with all the information you want. If you have already an international 12 you will find the latest information about our activities and of course a lot of hints. The name of our "organisation" is 12foot classic wood club (12footcwc) and sometimes also International 12 association.

12footcwc staat voor 12foot dinghy classic wood club. De nieuwe naam is International 12 association (I12A).
In 2012 is het idee voor deze club ontstaan in Luzern, Zwitserland. In de jaren daarvoor is samen met de Italianen geprobeerd eenheid in de jollenklasse tot stand te brengen. Helaas is dat mislukt. Moderne en klassieke principes liggen te ver uit elkaar. Er ontstond dus een splitsing: Italië ging door met modern plastic en Nederland met klassieke houten jollen. In diverse landen werden vanaf 2012 internationale Friendship evenementen georganiseerd, uitsluitend voor klassieke houten jollen, ook wel International 12 foot dinghy genoemd.

Een 12voetsjol is een overnaads geklonken zeilbootje van 12 foot (3,66m), ontworpen in 1913 door George Cockshott. In 1920 en 1928 zelfs een Olympische klasse, een klassieker dus. In Nederland bekend onder de naam 12voetsjol, de oorspronkelijke Engelse naam is International 12 of voluit International 12foot dinghy. In Duitsland 12fuss dinghy, In Italië 12piedi dinghi, in Japan A-class dinghy. Kortom veel verwarring, maar het geloof in alle landen is hetzelfde. Liefde voor een eigenzinnig klassiek Engels ontwerp, waar je veel plezier aan kunt beleven. Door het bouwen, het onderhoud, het zeilen van wedstrijden, maar ook het tourvaren. Vooral de gezelligheid is belangrijk. Koop een 12voetsjol en je krijgt er gelijk een familie bij

Welkom op deze website. Hier is alle informatie te vinden over deze klassieke zeil c.q. roeiboot met een rijke historie.

Copenhagen rules

Friendship series Copenhagen

The rules for dinghies participating in the Friendship Series originate in the Notice of Race of the Copenhagen Vintage Yachting Games 2018. The Copenhagen Rules are:

The International 12 will race with wooden clinker built boats according to the original design, and shaped, rigged and fitted accordingly. Vintage dinghies will generally be accepted, round wood should be solid, sails should be fixed to boom and lug such that no profitable in-race adjustment is possible. There should be no gear for profitable in-race adjustability of the mast foot. The original 1913 weight specifications are maintained in practice by requiring minimum sail-ready weight without ballast to be 26 stone 10 pound (169.6kg). The calculation is based on the specific weights of the prescribed wood types in the 1913 BRA Class Rules. The Rules add: "If alternative materials are allowed, the finished weight of each boat must not be less than that of the standard" (1913 BRA Class Rules, first paragraph: GENERAL). In individual cases the acting International 12 class authority shall decide with or without request.

1 Can Dutch original International 12 Foot Dinghies without a Dutch licence participate?
2 Can modern wooden AICD dinghies participate?
AICD wooden dinghies are around 25 kilo lighter, which makes them faster (more). This is achieved by thinning of wood which makes them unsafe in the up range of conditions raceable for International 12's, especially on tidal waters. Sailors of AICD dinghies are however very welcome and will be offered International 12 Foot Dinghies to hire.
3 Can plastic dinghies participate?
Sailors of plastic dinghies are however very welcome and will be gladly offered International 12 Foot Dinghies to hire.

Wim Bleeker was first in Copenhagen and got a prize with the names of the winners of 1920 and 1928 engraved. Anil Cetin the silver medal and Hans Reijers bronze. In addition to the international 12 foot dinghy, the Solings and O-Jollen also started. A great deal of attention has been paid to these competitions in the press and on the internet.

History of the International 12foot dinghy

olympische spelen
olympic games 1928 Amsterdam

It was in 1912 that the newly formed Boat Racing Association (BRA) launched a competition for the design of a small sailing and rowing dinghy which would be equally at home serving as a tender to a larger vessel or taking part in club races. The vessel should have an overall length of 12 feet, a beam of 4 feet 6 inches and a single sail of 100 square feet. The hull was to be clinker, planked in spruce on bent timbers. The competition was won by George Cockshott, an amateur boat designer from Southport, Lancashire, who had previously won prizes in other yacht and boat design competitions.

The design was baptised the 'A' Class One Design Dinghy but soon became known as the BRA 12 foot class. Following a few modifications the first orders were placed. By October 1913 the members of the West Kirby Sailing Club had already taken receipt of six BRA 12 dinghies. At West Kirby the design was again re-christened when it became known locally as the Dreadnought Class, with the entire fleet of these diminutive dinghies being named after contemporary British battleships such as the Audacious, Thunderer and Bellerophon. The Royal Engineer's Yacht Club was another early customer and before long their vessels were spreading throughout the British Empire. Soon the design spread to the Netherlands where it was greeted enthusiastically. By the end of the First World War there was a fleet of 140 BRA 12 footers racing there.

In the early 1920s the BRA merged with the Yacht Racing Association which hitherto had little interest in sailing dinghies. A subsequent International Yacht Racing Union (IYRU) conference decided that the BRA 12 footers should become the International 12 Foot Dinghy Class.

Some BRA members felt that an improved 12-foot dinghy should be designed for post-war use and approached Morgan Giles, one of the UK's best-known designers of small racing dinghies. Giles redrew the hull lines to allow a greater crew weight and improved sail carrying ability. He also moved the thwarts to improve the trim when the dinghy was being rowed. The new design performed better to windward, especially in light airs, and was stiffer and drier in a breeze. By this time eleven countries were sailing the International 12 Foot Dinghy and most of these were keen to adopt the new design, however the changes where opposed by the Netherlands and Belgium who had the largest fleets of original BRA 12 foot dinghies. Consequently, the International 12 Foot Dinghy Class retained George Cockshott's pre-war design. By 1920 the International 12 Foot Dinghy had become the most numerous One-Design class with over 200 boats in the United Kingdom and a large number overseas. The class was given further boosts when it was selected for the 1920 Olympic games in Belgium and again in 1928 when it was used as the single-handed boat for the games held in The Netherlands.

Lakken 12voetsjol


De hijsketting is een verplicht stuk inventaris. Voor het lakken best handig, omdat je de jol op een kant legt en zo de hele jol kunt lakken. Ook de onderkant. Een voordeel: geen stof in de lak en het draaien van de jol is ook niet nodig.
