FULL SCALE HYDRODYNAMIC FLOW STUDIES

The most sophisticated model testing cannot precisely duplicate every nuance of actual performance, especially the hull hydrodynamics. The article describes how a visual record of the vessel may be made by divers taking underwater photographs beneath the vessel as it passes overhead at various speeds, including turns, crash stops or dead starts. On the spot analysis of the films enables rapid location of areas of turbulence and cavitation causing erosion damage, drag and reduced performance.
