Abstract

A fin (3) for use on a propeller, the fin comprising a lift generating section (30) having a leading edge (302) and a trailing edge (303), and a pair of surfaces extending between the leading and the trailing edges thereby defining a tip and a root having a root chord; and a dihedral section integrally formed with the root of the lift generating section and having a rotation axis (BB) about which, in use, the lift generating system can be rotated to vary the dihedral of the fin, the axis being generally parallel to the root chord of the lift generating section.
