Notes:
One of the most successful sailing dinghies ever. (Only the SUNFISH or LASER can be considered in the same league.)
Originally designed and built by Lanaverre of France. (They built 32,000 according to one source.)
Licenses were later granted to other builders around the world.
In 1996, the International Class agreed to amend the deck layout.
1 Trapeze permitted.
Spinnaker: 97 sq.ft.
There is a 'Club' version of heavier construction and slightly different dimensions.
