Motorboat racing encompasses several types, including offshore powerboat racing, circuit racing, and drag racing. Offshore racing involves long-distance races in open waters, while circuit racing takes place on closed courses, often featuring tight turns. Drag racing focuses on straight-line speed over a short distance. Each type has its own set of rules, classes, and racing formats, catering to different skills and boat designs.

Generally, a circuit with multiple paths is called "parallel" because of the structure of the wiring involved. Parallel circuits have identical voltage on all paths, while current through each path is variable; whereas series circuits, having only one path, has constant current, but variable voltage.
An electric circuit connected so that current passes through each circuit element in turn without branching.
