In this paper, we used Harvard guldammer method to calculate water jet system parameters at maximum velocity of 35 knots such as inlet diameter and nossel diameter, pump power, pump type used and other parameters to obtain the Overall Propulsive Coefficient at that speed (Kim 1966).
The planning of the water jet propulsion system started by taking the Overall Propulsive Coefficient (OPCo) as a first step to calculate the parameters of the water jet propulsion system until the OPC was obtained in accordance with the predefined OPCo.
Based on the calculation of Overall Propulsive Coefficient (OPC), an equal value to the previous forecast was obtained so that the calculation could be continued.
