AbstractThis report describes work carried out at the Ocean Engineering Centre of B. C. Research to establish the limits of dynamic stability in calm water for planing hull forms which have been tested at the OEC. A literature review indicated that some hulls could become dynamically unsatable for certain trim angles, speeds and loading coefficients. Model experiments were carried out to confirm these predictions. It was found that predictions based on simple prisms were conservative compared to actual planing hulls. The predictions based on systematic series data were good for deadrise angles close to that of the parent hull form. It was concluded that the constraints affecting model size and carriage speed ensured that dynamic instability in calm water would only occur for very large initial running trim angles.
