Abstract: The paper presents a detailed analysis of experimental data, concerning decay roll oscillations of ship models, and the determination of an effectiveness of Short Wings Roll-Stabilizers as compared with bilge keels and active anti-rolling fins. The influence of end plates on the wing lift force, the SWIRS drag and the reduction of roll amplitudes owing to the increase of damping moments produced by roll-stabilizers are also considered.

Keywords: Rolling, bilge keels, short wings, damping, lift force, end plate, drag
