The Waterwitch is a chrome-plated outboard motor - the epitome of streamlined design. Streamlining, in which the form is inspired by aerodynamic principles, typically features curved lines, rounded corners, and individual elements with a teardrop-like design. Very fashionable in the United States in the 1930s, it was intended to evoke the impression of speed. The idea of making objects streamlined was prompted by new methods of transport such as the automobile and the airplane and the enthusiasm for high speed associated with them. The Waterwitch outboard motor can be considered an icon of streamlined design. It was built from aluminium and steel, reflecting the modern way of life, and lending it a certain visual and functional lightness out on the water. The Waterwitch originally went on sale for $39.95. Customers were attracted not only by its high-powered performance but also by its appearance. The motor added a sense of glamour to boating and heralded the increasingly important role that design would play in brand development.
