Henry Ashton Highet, commonly known as Harry Highet, (27 January 1892 – 2 February 1989) was a New Zealand civil engineer famous for his 'P-class' yacht design.
This class is famous for being the sailing trainer vessel for many new entrants into the sport, and virtually every famous New Zealand yachtsman, including Sir Peter Blake and Russell Coutts, learnt to sail in one.
