Instability of a ship towing system indicated by vigorous yaw motion of a towed ship may reduce the safety of the navigation especially in the restricted with heavy congestion waterways. To stabilise this towing system, a comprehensive investigation on a towline configuration is therefore required. This paper presents Computational Fluid Dynamic (CFD) approach to analyse the unsteady yaw motion characteristic of a towed ship using symmetrical bridle towline. Several towing parameters such as various towing point locations on the symmetrical bridle towline and towing’s velocity have been taken into account. Here, a towed ship designates as 1B (barge) is employed in the simulations. The results revealed that the subsequent increase of towing point location on the symmetrical bridle towline will reduce significantly her unsteady yaw motions by 99.67%, improves barge course stability. In addition to increasing towing’s velocity, it gradually leads to have poor course stability as the yaw motion increased by 23.83% meanwhile slewing period decreased by 20% as velocity increased
