What are described are a propeller for driving of watercraft, having propeller blades (2, 6, 9, 15) and a metallic hub (1, 7, 8, 14, 31) for bonding to a ship's shaft, and a method for production thereof. The propeller blades are manufactured from polyamide 12 C or a composite material composed of polyamide 12 C with a long and/or short fibre core. The propeller blades or components of the propeller blades are mounted on the hub, or the propeller as a whole consists of polyamide 12 C or a composite material composed of polyamide 12 C with a long and/or short fibre core and the hub encapsulated with PA 12 C. This can achieve an improvement in thrust performance and reduction in acoustic signature compared to metallic propellers.
