By the late 1960s the class was adopted by a few UK university sailing clubs for training and team racing.

The class adopted a policy of "prudent evolution" so as to allow development without making existing dinghies obsolete.

The boat is much more simple to sail, yet lacks the performance of the original dinghy due to its extra weight.

Only the International 14 and Optimist (dinghy) class association hold a team racing based World Championships in addition to the two discipline led events.
