Regatta Grou, Netherlands

12footdinghies took part in a regatta near Grou in the North of the Netherlands. As shown in the video, the start and initial section of the course are important. This lake is the site of the annual Princenhoftocht and is a staple event of the international Friendship Series of regattas organized for the 12footdinghy (12voetsjol)

International 12 Foot Dinghy

Training event in Grou, Friesland, the Netherlands

The Internatonal 12 Foot Dinghy was designed in 1913 by the British maritime architect George Cockshott; as suggested by its name, the open sailboat measures 12 feet in length (3.66 m). Less obvious perhaps is that the original design made use of a common hull construction during the period, a technique known as lapstrake whereby planks are fastened together with copper rivets. The design quickly became popular and achieved international and classic status when approved as an Olympic class for the games held in 1920 and 1928. In the Netherlands the boat became known as the “12voetsjol”; in Germany as “12fuss dinghy”; in Italy as “12piedi dinghi”; in Japan as “A-class dinghy” and in the UK as “International 12 Foot Dinghy” or “International 12” in abbreviated form.
With such a range of names some confusion resulted, but the core remained intact: a love for a unique classical British open boat design capable of providing owners with much pleasure in building, maintaining and sailing the craft, either in organized competitions or in more relaxed touring events. Spanning across both competitive and tour sailing of the Internatonal 12 Foot Dinghy is a feel of comraderie and pleasure among the sailors. It is almost as if when one becomes the owner of an Internationl 12 one becomes a member of a large and open and international family of dinghy sailors.
Welcome, in other words, to this website for the historic International 12 Foot Dinghy. Much information is available about this classic open sailboat - also equipped with oars for those moments when the wind vanishes.

Our mission

Nicky Arnoldus from Canada

Our mission is to keep the International 12 Foot Dinghy 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 12footdinghy classic wood club (12footcwc) and also International 12 Association (I12A). Welome to this website for aficionados of the International 12 Foot Dinghy. A classic, eco friendly, so just wood.

12footcwc / International 12 Association

Rifat Edin from Turkey (left) and Mark Delaney from Ireland

The earlier name “12footcwc” stands for “12footdinghy Classic Wood Club”. The current name is “International 12 Association“ (I12A).
The idea for this association dates from 2012 during an meeting in Luzern, Swiss. Prior to that year effort was made to achieve unity among the various national associations of the International 12 Foot Dinghy, particularly with the Italian branch. The efforts unfortunately did not succeed, mainly because of differences regarding modern and more classic boat construction principles. A consequence of those differences was a division between those giving preference to fiberglass hull construction, as in Italy, and those adhering to the original wood lapstrake hull design, as advocated in the Netherlands.
Since 2012, regattas have been organized under the banner “International Friendship Series”, and are restricted to the classic wood design of the International 12 Foot Dinghy.
The logo below was designed by Bert Hamminga, called the “Admiral” of the I12A. Bert passed away in 2021; A blog entry commerates his contributions to the association.

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 rules for these games, known as the Copenhagen Rules, stipulate that:
The International 12 constitutes 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 in-race adjustment is possible. There should be no gear for 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 British Boat Racing Association (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). The acting International 12 class authority is empowered to decide individual cases, with or without request.

FAQ's
1 Can Dutch original International 12 Foot Dinghies without a Dutch certification participate?
ANSWER: yes
2 Can modern wooden AICD (Associazione Italiana Classe Dinghy 12') dinghies participate?
ANSWER: no
AICD wooden dinghies are around 25 kilo lighter, which makes them potentially faster. This is achieved through use of thinner planks of wood which makes the boats unsafe in conditions sometimes encountered by competitive International 12 crafts, especially in tidal waters. Sailors of AICD dinghies are, however, welcome and will be offered International 12 Foot Dinghies for hire.
3 Can plastic dinghies participate?
ANSWER: no
but sailors of plastic dinghies are welcome and will be offered International 12 Foot Dinghies for hire.

A total of 19 participants from 9 countries registered for the event held 18-22 September, and constituted a reunion of former Olympic classes. The international 12 was an Olympic class in 1920 and 1928. Wim Bleeker was first in Copenhagen and got a prize with the names of the winners of 1920 and 1928 engraved. Anil Cetin came in second and received the silver medal;Hans Reijers placed third for a bronze medal. In addition to the international 12 Foot Dinghy, the class boats Solings and O-Jollen also took part. Considerable attention was given to these competitions in the press and on the internet. See the links below.

History of the International 12 Foot Dinghy

olympische spelen
Olympic Games 1928 Amsterdam

It was in 1912 that the newly formed British 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 that 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.

In the Netherlands, advertisements for “12voetsjollen” (Internatonal 12 Foot Dinghies) can be found at the site of the Twaalfvoetsjollenclub and at the online site for used items Marktplaats. If you need help buying a dinghy, don't hesitate to ask the rear commodore.


There are, generally speaking, three price classes:
1 Old boats: between 3000 -and 7000 euros (often requiring restoration)
2 Second-hand in excellent condition: Between 8000 and 12000 euros
3 New or practically new: 18.000 - 25000 euros.
The above prices are indicative; recently, asking prices have dropped somewhat.


Is there any difference in sail performance and speed of boats in the three price classes? None, or hardly none. The qualities of the helmsman remain the most important factor.
Members of the Friendship Series are very open to providing advice and second opinions on candidate purchases. Two wharfs in the Netherlands are specialized in building the International 12 Foot Dinghy: Jachtwerf van der Meer and Jachtwerf de Groot. They often have recently boats for sale.

Two and three dimensional CAD models of the International 12 Foot Dinghy are available from Vasileios I. Koutsovoulos at the Greek company Mechdrafting

Drawings of the official Dutch "12voetsjol / International 12 Foot Dinghy" may be purchased from the Dutch watersport association for 125 Euro. See watersport tekening kopen.

In addition to the drawings,the Dutch classrules 2020 are available. The Dutch classrules from 2016 are translated into English. See class rules English 2016. You will need the class rules 2020, however, if you want to qualify for official Dutch certification. In the Netherlands are about 200 classic wooden dinghies that are certified.

The first class rules, published in the Yachtsman 1913 give an impression of how the designed was conceived.

An alternative to buying a new dinghy is restoration. Dinghy 770 is illustrative of this alternative: while the original hull was in very bad condition, the final result shows a boat as if new. And fast: Dinghy 770 was the Dutch champion in 2020. The proud owners are Arjen Kort and his father Harry Kort.

Covid-19 was stronger then Admiral Bert Hamminga who died of complications from the disease in April 2021. Bert found this hat in the Baldeneysee and had the excellent idea to promote it as the Friendship Hat. Henceforth we call this hat the Bert Hamminga Hat, and the winner of the Friendship Series has the honor to wear it for a brief moment, long enough for a picture to be taken. Clearly, Bert was a man blessed with much humor.
