Abstract: This paper deals with the data gathering phase for a 21-foot long planing catamaran. The boat experiences a take-off phenomenon at high speed which needs to be countered. An overview of stability problems in high speed hydroplanes is described with possible solutions recommended. A subsequent gathering of data using laser scanning and computational fluid dynamics (CFD) analysis of the boat are described. The paper ends with a look at the initial developments of stabilising systems for the boat.

Keywords: pitch control; data collection; mathematical modelling; pitch stabilisation; high speed catamarans; CFD; computational fluid dynamics; hydroplanes; laser scanning.
