Although one of the oldest organized sporting activities, sailing in the early first part of the 20th century was not uniformly organized. This had a lot to do with national traditions as well as with the fact that there were no standardized boat types with uniform building instructions and measurements. Also a lot of development was done in the area of boat design and boat building. The shape of a boat, specifically its length, its weight and its sail area, are major parameters that determine the boat's speed. Several initiatives were started to create a formula that made it possible to have boats race each other without having to calculate the final result. But the different countries initially could not agree on an international system. At the Olympics of 1900 it was clear that sailing was not ready for international competition, and something had to be done.
