Підсумок	The Holtrop-Mennen Method is an empirical regression-based technique for predicting total ship resistance from geometric parameters and operating conditions. Developed by Jelte Holtrop and Gert Mennen in 1982, the method decomposes total resistance into friction, pressure, wave-making, and form drag components, each estimated from ship dimensions, hull shape, and speed. Widely adopted in maritime engineering, the Holtrop-Mennen method remains the industry standard for preliminary ship design and propulsion power estimation.	Propeller lifting line theory is a mathematical framework for analyzing and designing ship propellers by modeling each blade as a lifting line with circulation distribution. Developed by Sydney Goldstein in 1929 and refined by Kerwin and others, the method accounts for blade loading, wake effects, and propeller interactions. Lifting line theory provides efficient predictions of propeller thrust, torque, and efficiency and remains standard in preliminary propeller design and optimization.
