The P Class yacht was designed in 1920 by Harry Highet as a training boat for children. Although it was first sailed in Tauranga, it was not until the Ponsonby Cruising Club adopted the small craft in 1941 that it really took off.
Many notable sailors trained in the tiny boats in the Hauraki Gulf including Sir Peter Blake, Dean Barker, Sir Russell Coutts, Chris Dickson and Leslie Egnot. They were difficult boats to sail, particularly in heavy winds, as they have a tendency to nose-dive going downwind. This honed the balancing skills of the young sailors.
