In order to maintain the safety of sailing, it is necessary to determine the relationship between the vessel and any obstacle that may appear on its way. This relationship is essentially the distance of the obstacle from the vessel. It is therefore very important to identify a zone or zones surrounding the ship that determine the location of the target for it in order to prevent the presence of any obstacle within it. In this research, a fuzzy system is designed to calculate the radius of three proposed zones, namely the forbidden, dangerous and safe zone, based on human experience, taking into consideration the rules of COLREGS (International Regulations for Preventing Collisions at Sea).This system is Multi Input Multi Output (MIMO) and has three inputs that are the length, speed of the vessel, and sea state; and it has three outputs that are the radius of the three zones (forbidden, dangerous and safe zones). The proposed system is adjustable according to length and speed of vessel, and sea state.The system is designed and tested using MATLAB. The results were showed to marine experts who said that are good.
