The induced velocity of the bow and stern bilge vortices generated around a wallsided model is measured using a five-hole pitot tube to study the behaviour and property of the vortices. The numerical calculation of the locus of the bow bilge vortex is also carried out by applying the line vortex approximation and the conformal mapping method. Some of the main results obtained are as follows: 1) The structure of the wake distribution deformed by the induced velocity of vortices is experimentally clarified. 2) The diffusive interaction of the counter-rotating components of vortex causes the decay of the vortex circulation. 3) The numerical calculation agrees well with the experiments.
