Resistance Tests of a Systematic Series of U.S. Coast Guard Planing Hulls

Abstract

Resistance experiments were performed on a systematic series of models based on the United States Coast Guard 47-foot Motor Lifeboat (MLB) hull form. The series includes three models with varying length-to-beam ratios and one model with transom dead-rise angle variation. Resistance tests were completed on each model for a range of conditions, with displacements varying from 298 Ibs to 680 Ibs and longitudinal center of gravity located at 38% and 42% of the length between perpendiculars (measured forward of the aft per- pendicular). The results are presented as model scale values in the form of; RT/delta, SDYN, CR, LCG Heave, and Pitch angle. Additionally, EHP was calculated for the 47-foot MLB from 5628 model data and compared with EHP calculations from previous 47-foot MLB model test data.
