Racing boats operate under high-speed conditions and repetitive rapid maneuvers, where the performance of the propulsion system plays a critical role in race outcomes. The propeller is a key component that converts engine rotational power into thrust and must maintain structural stability under high rotational speeds and hydrodynamic loading. In this study, a racing boat propeller based on a carbon fiber reinforced plastic(CFRP) laminate structure was designed and a manufacturing process was established. The proposed propeller consists of a two-blade configuration in which the hub and blades are integrated into a single structure to minimize structural discontinuity under high rotational conditions. The composite propeller was fabricated using a prepreg lay-up process followed by vacuum-assisted thermal curing. In addition, flat laminate panels with the same carbon fiber lay-up configuration as the propeller were simultaneously manufactured to prepare bending test specimens for process verification. Flexural tests were conducted to evaluate the mechanical characteristics of the CFRP laminate structure. The results of this study provide fundamental data for the design and manufacturing of lightweight CFRP-based racing boat propellers.
