Abstract

The understanding and quantification of hydrodynamic lift requires a full appreciation of the phenomena associated with high-speed planing. Repeatability of results is a major problem with planing craft experiments due to the complexity of fluid flows; wetted lengths, for example, are difficult to measure because of the obscurity created by spray-jets. This difficulty in measurement can produce subjective interpretation.

Therefore, reducing hydrodynamic lift using uncertainly defined factors, such as wetted data, can be misleading. This paper outlines an experimental method, Computer Vision Data Acquisition (CVDA), that can remove questions of uncertainty regarding dynamic phenomena by remotely capturing large amounts of planing data for immediate and archival use. An example of the importance of this form of data capture and analysis is described by the ability to validate predictive formulae for planing performance in calm water, and to further advance these formulae for predictions outside their designed realms: in waves.
