The acknowledged genius of motor boat design in America was the naval architect John L. Hacker. His pioneering work, including the invention of the V-hull and the use of dedicated petrol engines revolutionized boat design from as early as 1908, when he founded the Hacker Boat Co.[from wikipedia]

The type of hull depends on the usage and type of water that the boat is being used in. Types of hulls include displacement hulls, vee-bottom hulls, modified vee-bottom hulls, deep-vee hulls and trim tabs for vee-bottom hulls.[from wikipedia]

Although the screw propeller had been added to an engine (steam engine) as early as the 18th century in Birmingham, England, by James Watt, boats powered by a petrol engine only came about in the later part of the 19th century with the invention of the internal combustion engine.[from wikipedia]

A motorboat has one or more engines that propel the vessel over the top of the water. Boat engines vary in shape, size, and type. Engines are installed either inboard or outboard.[from wikipedia]
