FULL-SCALE TRIALS AND ANALYSIS OF HIGH-PERFORMANCE PLANING CRAFT DATA

Comparisons are given for predicted and full-scale speed-power-RPM data for planing craft. The results indicate that correlation is significantly influenced by propeller cavitation and its uncertain effects on propulsive factors. Correlation factors are offered for both horsepower and RPM with indications that careful attention to underwater design details is very important for speeds above 25 knots.
