On Fast Ferries the top speed can cause a not quite dynamic behaviour of the vessel affecting the travel comfort of the passengers. However the high speed allows to realize through a set of properly controlled hydrodynamic appendixes a very sophisticated stabilization system able to reduce drastically pitch, roll and yaw of the platform. On this regard RMS, due to its huge experience with fast ferries realized by and with RCN, is able to propose MSI proven systems with very high performance.
