We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

5.5 Metre — The class was designed by Charles E. Nicholson in 1937 as a redesign of the 6-metre class
5.5 Metre — The class replaced the International 6-metre at the 1956 Olympic Games in Melbourne
6 Metre — The Scandinavian Gold Cup transferred to the 5.5 metre class in 1965, not 1953.
6.5 Metre — The 6.5 Metre class was not used as an Olympic class during the 1920 Olympics.
6.5 Metre — The claim that the formula was inspired by the New York Yacht Club's 1903 rule is unsubstantiated and likely incorrect.
8 Metre — The International Rule was established in 1906, not 1907.
8 Metre — The first 8 metre yacht to use Bermuda rig was not Ierne as stated; the details are conflated: Morna (later Ierne) was first but converted, while Senga was the first built with Bermuda rig from the start.
8.5 Metre — The 8.5 Metre class was used in the 1920 Olympics and had entries; the claim that 'no entries were actually made' is incorrect.
8.5 Metre — The Jauge chemin de fer formula was established around 1892 by the Union des Sociétés Nautiques de France, not first worked out in 1903 by Louis Dyèvre.
12 foot dinghy — The first World Dinghy Championships were held in 1922, not 1924, and were organized by the Royal Yacht Club of Belgium, not specifically the Brussels Royal Yacht Club.
12 foot dinghy — The 12 foot dinghy was the first design approved at the 1919 International Conference, not the fifth; the 'Section 5' designation refers to a later classification system, not the order of approval.
12 m2 Sharpie — The claim that Rolly Tasker and John Scott won Australia's first Olympic sailing medal is incorrect; Australia's first Olympic sailing medal was a silver won by Jock Sturrock and crew in the 5.5 Metre class at the 1956 Melbourne Games.
12 m2 Sharpie — The claim that original boats have not raced internationally since the 1960s is contradicted by the earlier statement that competitive racing still takes place in the UK, Netherlands, Germany, and Portugal, and that European Championships are held annually.
12 Metre — The claim that the 12 Metre class was used in the Olympic Games of 1908, 1912, and 1920 is incomplete: the class was not used in 1924, so the original statement is correct and the flag is mistaken.
12 Metre — The statement 'No new 12 Metre boats have been built since 1987 save one' is inaccurate: several new 12 Metres have been built after 1987, including 'Kiwi Magic' (1992) and 'Lionheart' (2019), making this a genuine factual error.
