Firefly (dinghy)

The Firefly is a British sailboat that was designed by Uffa Fox as a one design racer and first built in 1946. The boat was originally named the Sea Swallow. It was an Olympic class and raced at the 1948 Olympics.

The design was initially built by Fairey Marine in the United Kingdom, starting in 1946 until the end of 1972. It was then built by Vic Lewis Boats from 1973, in glassfibre, using moulds by Craft Mouldings. In 1976 Knight and Pink Marine re-started the production of wooden boats. Omega Boats built a foam sandwich version of the design and then Porter Boats produced it up to 1995. From 1997 to 2023, production was by Rondar Raceboats in the UK. Whitecap Composites in the United States also built Fireflies. As of the summer of 2023, it is now built by Ovington Boats in the UK and remains in production. More than 4,270 Fireflies have been completed.

The Firefly is a recreational sailing dinghy, initially built predominantly of hot-moulded plywood, glassfibre construction was authorized by the class starting in 1965. A rotating mast was introduced in 1970.

The design has a fractional sloop rig, a plumb stem and transom, a transom-hung rudder controlled by a tiller and a retractable centreboard. It displaces 260 lb (118 kg).

The boat has a draft of 4.25 ft (1.30 m) with the centreboard extended and 10 in (25 cm) with it retracted, allowing operation in shallow water, beaching or ground transportation on a trailer.

The design is raced without a spinnaker.

The Firefly has a Portsmouth Yardstick handicap of 1168 (in the RYA scheme) and a D-PN of 99.6 in the US Sailing system.

The boat is supported by an active class club that organizes racing events, the National Firefly Association.
