A STUDY OF PLANING CATAMARAN HULL AND TUNNEL INTERACTIONS

A high speed, low displacement set of catamaran hulls has been model tested with various hull separations and tunnel heights. Symmetric, axisymmetric and unsymmetric hull forms have been tested and compared in terms of resistance to determine the interaction effects of the sponsons. A computer program for the prediction of power for prismatic planing boats has been modified to include catamarans.
