Congratulations on your choice of the 49er and 49erFX. Welcome to the worldwide group of 49er sailors.
The 49er has a noble lineage from the skiffs of Sydney Harbour. Skiffs enjoyed their first official regatta in 1827 and have raced continuously ever since. Elsewhere in the world skiffs have been increasingly seen, as the regatta circuit has expanded to Europe and the USA, and also via television coverage.
The 49er Class rules are available on the ISAF server here.
