This unusual prototype has ties to amphibious ATV’s. It’s called the Fisher, designed by ex-Ford employee Gordon Fisher while working under Canadair Ltd., in Montreal, Québec. Two were produced between 1963-64. Fisher utilized a complicated driveline with 16 wheels that were belt driven, making it prone to terrain debris. Popular Science featured Fisher in December 1964.
Powered by a nine-hp, single-cylinder, two-stroke Rotax engine, the vehicle carried a 300-kg (600 lb.) payload at up to 19 km/h (12 mph), could negotiate a 50 per cent grade, and could swim.
The end goal was to secure a military contract, but the vehicle had too many design flaws and the US military suggested a total reconstruction. Ultimately Gordon Fisher would go on to design the Sur-Trek in 1967.
