To provide a ship performance estimation method, a performance estimation program, and a performance estimation system capable of accurately estimating a ship performance.SOLUTION: A ship performance estimation method includes: a hull condition acquisition step S1 of acquiring a hull condition of a ship; a navigation condition acquisition S2 of acquiring a ship navigation condition; a water-tank test step S3 of finding a drag coefficient and a self-propulsion factor of the ship by conducting the water-tank test based on the hull condition and the navigation condition using the model ship of the ship; a CFD calculation step S4 of finding the drag coefficient and the self-propulsion factor of the ship by carrying out the CFD calculation based on the hull condition and the navigation condition; and a step S5 of correcting the drag coefficient and the self-propulsion factor, where the difference between the drag coefficient and the self-propulsion factor is found by the water tank test and the CFD calculation, the difference is corrected based on a setting number of variables for the navigation condition in the water-tank test, and the correction values of the drag coefficient and the self-propulsion factor are obtained.SELECTED DRAWING: Figure 1
