A Sea tractor is a motor vehicle designed to travel through shallow seawater, usually carrying passengers on a platform suspended typically 2 meters (6 ft 7 in) or so above a tractor-like chassis. Early models of Sea tractors had a 20–40 horsepower (15–30 kW) motor and a 10 person capacity.
The sea tractor was most popular during the early 1930s, as a unique way to give scenic tours to patrons of waterfront hotels and resorts. In other applications, Sea tractors were used merely as a ferry through shallow waters.
Sea tractors are hardly used in present time - as boats, ferries, and other aquatic vessels often serve their function much more efficiently and comfortably.
