ROTATING ARM EXPERIMENTS FOR SWATH 6A MANEUVERING PREDICTIONS

This report contains the results of model experiments on the horizontal plane characteristics of a Small Waterplane Area Twin Hull (SWATH) ship in the Rotating Arm Facility of this center. Speed, drift angle, draft, roll angle, yaw rate, and rudder deflection angle were varied for three rudder configurations including a novel forward foil. Nondimensional derivatives are reported along with a comparison of rudder effectiveness for each of the rudder configurations. The results provide a data base for simulation of craft turning.
