HYDROPLANE EXHIBITION

Limited hydroplanes use smaller, typically automotive engines. To keep things fair, each class is limited to a specific size engine. The size of the engine is indicated by a capital letter. The letter also indicates wether the motor is stock or modified. In vintage exhibitions there are rarely enough boats of a specific class to warrant a heat that is entirely made up of a single class, so they are combined into one of four groups: Small, Medium , Large or Flat bottom. The chart below explains the numbers, the size and which vintage heat a class will typically be assigned to.
