A controllable pitch propeller for a vessel comprises a propeller hub, connectable to a drive shaft for rotating the hub about a longitudinal axis. A travelling member is arranged at least partially within the propeller hub to be moved in a direction along the longitudinal axis and is connectable to an actuating device for creating movement of the travelling member along the longitudinal axis. A plurality of propeller blades each having a propeller blade base are mounted on the propeller hub, wherein each propeller blade has a blade angle that is adjustable through at least 140 degrees by rotating the propeller blade about a respective pivot axis oriented transversely with respect to the longitudinal axis. A linkage arranged between the travelling member and the respective blade bases causes adjustment of the blade angle of each propeller blade by converting the movement of the travelling member into rotation of each propeller blade over a range of at least 140 degrees.
