This study aims to reduce roll motion of a ﬁshing boat which arises from disturbing hydrodynamic effects by means of ﬁn roll stabilizer. It is assured that roll motion with nonlinear damping and restoring moment coefﬁcients are down to the desired level through classical PID and modiﬁed PID algorithms. At the time of sailing, stability, a very important concept, was examined using Lyapunov direct method taking initial conditions into consideration, and it was noted that the system was generally stable. In addition, NACA 0015 model was used for the ﬁn roll stabilizer, and ﬂow analysis was carried out with Computational Fluid Dynamics (CFD) method. In the simulation results, when the same gains were used, modiﬁed PID controller algorithms were relatively more effective compared to PID in the ﬁn roll stabilizer system
