This boat was home-made by George Davison, a engineer, in the boat workshop at the Hamilton farm. George built the two-stage jet unit from the first trial Chinook intake casting, 6" scrap pipe, steel scrap and two experimental, hand-made steel impellers. The boat has a Briggs Oregon ply hull which has been fibre glassed by a later owner.
It is mounted on its original overhead suspension trailer, designed for launching into shallow water. Engine: Ford 100E Prefect Arnott supercharger. Jet Unit: 1956, serial No. 2, 6/8 inch diameter two-stage axial flow, 3 3/4 inch nozzle, sliding gate reverse. Hamilton jets were first developed on "Irishman's Creek Station", between Lake Tekapo and Lake Pukaki in the South Island of New Zealand
