A propeller for driving watercraft, having propeller blades and a metal hub for connection to a ship's shaft and a method for the production thereof are described. The propeller blades are manufactured from polyamide 12 C or a composite material made of polyamide 12 C with long and/or short fiber cores. The propeller blades or components of the propeller blades are mounted on the hub, or the propeller as a whole is made of polyamide 12 C or a composite material made of polyamide 12 C with long and/or short fiber cores and the hub encapsulated with PA 12 C. This can achieve an improvement in thrust performance and the reduction in acoustic signature as compared to metal propellers.
