One Idea – Three Rules – Four Epoques

Six Metre Sailing  – 100 Years of Elegance and Performance

1907 The First Rule


“The International Rule, also known as the Metre Rule, was created for the measuring and rating of yachts. Prior to the ratification in 1907, countries raced yachts under their own rules and any international competition was always subject to various forms of handicapping. These were often subjective and certainly open to protest.“ This quote shows the importance and significance of the Rule for modern yacht racing. Alfred Benzon from Denmark initiated the idea, and in 1907 the International Yacht Racing Union (IYRU) ratified this first International Rule.

L = the length of the waterline, B = maximum beam, G = the „chain girth“ from covering board, around the keel and back up, d = the difference between the „chain girth and the „skin girth“ at a specific measurement point, S = sail area, F = freeboard


This „First Rule“ led to relatively short boats with huge sail areas. These early boats had a hull length around 5.5 to 6m with long bowsprits so that the length overall was around 9.5 m. The narrow beam, about 1.75 m, and sail areas between 50 and 60 sqm in the gaff rig caused boats that were very wet to sail, with limited seaworthiness.

But even when the new Rule was in competition with the S-Rule and the Square Metre Rule in other countries, it was a big success. By 1914, 208 Six Metre boats were built to the International Rule with fleets in Norway, Sweden, Denmark, Germany, England, Italy and France.

The 6 Metre Class was chosen for the 1908 London Olympic sailing events held in the waters off Ryde on the Isle of Wight, and the 1912 Stockholm Olympics at Nynäshamn.

1919 The Second Rule



The second epoch of the Metre Yachts  began after the first World War. Once again meetings were held in London, in October 1919. To encourage more seaworthy yachts the Rule was modified to the proposals made by designer John Anker.  The „B“ measurement was omitted from the rule and replaced by a minimum beam, so it was no longer possible to build a really narrow boat. The difference „d“ and the Girth „G“ were not penalised as much as before, but the sail area was penalised more. This was one reason for the introduction of the „genoa“ in 1926, because the sail area was measured from the size of the foretriangle, rather than the actual size of the headsails. These alterations to the rule led to huge changes in the 6 Metre Class. The boats became longer and heavier, with „Marconi“ (or „Bermudan“) rigs with a sail area around 40 sqm. The waterline length, which was now measured at 90 mm (1.5 per cent of the 6m class rating) above the waterline, increased to 7m. The displacement went up from 3 to 4 tons.  New nations like the USA, Argentina, Uruguay and India became members of the 6 Metre community, but Scandinavia remained as the centre of racing. The Scandinavian Gold Cup was inaugurated and was the forerunner of a World Championship. Again the Sixes appeared in the 1920 Antwerp Olympic sailing event held in the waters off Ostend, in the 1924 Paris event at Le Havre, in the 1928 Amsterdam event on the Zuidersee and in 1932 at Los Angeles.

1933 The Third Rule



As before the designers tested the rule to its limits and once again the boats started to become less seaworthy, due to narrow beams and lack of bow buoyancy. Again the IYRU reacted and 1933 the rule was simplified and changed to the rule that is still in force today. The „G“ measurement was removed,  which allowed designers to make the keel deeper with the ballast lower. That makes the boats more stable and seaworthy. Together with the change of the girth height at the bow, the boats became more buoyant forward. The Sixes were chosen for the 1936 Berlin Olympic games at Kiel, for the 1948 London Olympics at Torbay and for the last time 1952 in Helsinki in the waters off Harmaja.

1970 The Open Divison or the so called Moderns


The next big step for the class was in the years 1975 and later, when a number of new boats were built. The boats of this time started to look very different. The rudder was separated and no longer hung on the back of the keel, becaming more effective. The shape of the sterns and the bow style changed, but the biggest improvement was the keel. The legendary win of Australia’s 12 Metre at the America’s Cup showed the potential of the new „Wing Keels“. The 6 Metre class became one of the most innovative development classes at this time. In 1973 the World Cup was presented as the trophy for the World Championships, leading to outstanding regattas with the top sailors of the world.


Ein Gedanke zu „One Idea – Three Rules – Four Epoques

  1. I write in english, as my german is a little bit rusty. Hope this is okay.

    Just found your website and wanted to tell you that Lillevi looks just great! A magnificent sailing yacht!

    Many years ago I was looking for information on Zake Westins other 6mr yacht Merenneito and found that she was owned by a boat builder in Canada who wanted to restore her for a buyer. I was young at the time and simply could not afford the project, even though I was tempted. Merenneito was later bought by a Finnish sailor and I have many times seen her in my home town Hanko in Finland.

    One other reason that I started to look for Lillevi on the internet, except that I think Zake Westin did draw very beautiful yachts is that the owner of Lillevi, and also Merenneito, was Hemming Elving. Elving sailed for the same club as I do HSF (Hangö Segelförening). My father remembers him, and his yachts, very well, as Elving stored his 6mr yachts just 150m from our house, when my father was young. Elving did own Lillevi for appr. 20 years.

    Perhaps this little story is of interest of you. Anyway, I hope all the best for Lillevi.

    Kind regards,
