Hinterhoeller Yachts was a Canadian boat builder based in St. Catharines, Ontario.
[1][2][4] The company went on to build designs such as the Redwing 30, Invader 36, Douglas 31/32 and the Frigate 36 during the late 1960s.
By 1975 Hinterhoeller had grown tired of working in a large corporate environment, sold his shares and retired.
[2] The reformed company engaged yacht designers Mark Ellis for cruising boats like the Niagara 35 and the Nonsuch line and Germán Frers for racing boats like the Niagara 31.
They are noted for their distinctive hull shapes, large interiors and unstayed catboat rigs.
George had been impressed by the Aurora 40 from Mark Ellis and contracted him to design the Niagara 35.
