A propeller made of reinforced plastic material has a number of reinforcing sections 4, 6, which are arranged so that the direction and/or structure and/or the material of the reinforcement in a section 4 differs from the corresponding reinforcement in a second section 5, 6, but so that the reinforcement in one and the same section in the main runs in the same direction, in addition to which the propeller is also designed so that the change of shape occasioned by loads and stresses means that the pitch is optimized with increasing load. <IMAGE>
