This boat introduced into the competition at the Sydney Games is an ultra-rapid, 15m_ sailing dinghy with a long mast and large sail. It is derived from a squat Australian boat called an 18-footer which can attain speeds of over 30 knots. The more slender version used in competition is called a 49er on account of the boat's dimensions: It is 4.9 metres long. It is sailed by a two-man team.This dinghy accelerates and decelerates very quickly and needs wind to remain balanced. If not, the sail tends to capsize, in other words, to turn over.At the Sydney Games, Finnish yachtsmen Johanson and Jarvi won the first Olympic title.
