The Fly class is a singlehanded sailing dinghy designed by R. Fillery and later modified by K. Ford.
It was intended to be built at home, and appears to have been developed as a youth trainer for the British Moth.
The original club was founded in Leyton and sailed on the river lea.
The modifications to the original design made by Kenneth Ford were mainly a deeper free-board allowing a deeper cockpit with larger roll decks allowing larger children and adults to sail the class.
The club did host an international event for the class, on the river Lea during the 60s.
