Highlights
Nowadays, it is important to consider many points in the ship design process
Experiment From the results of the experiment using the towing test method, certain velocities were tested on the ship model and some of the total-resistance forces were found
In the 2-kg loading condition, the total resistance experienced by the ship model with a stern foil tended to decrease compared with other loading conditions; it could be concluded that the stern foil worked optimally under this condition
Summary
It is often necessary to make improvements or apply new inventions based on a previous design, starting with machining efficiency the impact on production costs. More research has focused on the development and modification of ship performance, and the important objectives will focus on resistance and optimising the efficiency of the ship’s propulsion system. The main variables in the ship design process are Length (L), Beam (B), Draught (T), Coefficient block (Cb) and Velocity (V). Changing these variables may affect the optimisation of the design and ship performance, and the results of the calculation of efficiency will depend on the changes to each of them (Edalat & Barzandeh, 2017; Grigoropoulos & Chalkias, 2010)
