High Quality Content by WIKIPEDIA articles! Originally designed by Peter Milne in 1962, the Fireball is a one-design high-performance sailing dinghy. The Fireball is sailed by a crew of two, and sports a single trapeze, symmetric spinnaker and chined hull. The class is strictly controlled, but has adapted to advances in building techniques. The hulls (plywood, FRP or composite) have a strict minimum weight limit of 175 lb (79 kg) (with correctors).
