These are important questions in deep water conditions where telecommand is impracticable. The present study is based on the behaviour of a stern shaped as a fishtail in three different ways, and considers several attack angles. The solutions of the Navier-Stokes equations are computed with the OpenFOAM library. An open source library based on the Finite Volume Method (FVM) using C++ language. An analysis of the effects of the fishtail shape on the resistance and stability is based on the calculation of the averages drag, lift and torque. A filtering on the Fourier transform of the torque is used to discuss the manoeuvrability in each case.
