<p>An apparatus (10) for adjusting the trim of a marine hull (1) includes a blade (11) having an upper edge (11b) and lower edge (11a). An expandable chamber (13) is located above the blade (11). The expandable chamber (13) is defined by a chamber wall. At least part of the chamber wall is formed of an elastically deformable material. The chamber wall includes a lower chamber wall portion (14a) fixed to the blade upper edge (11b). A pressure supply (15) communicates with the expandable chamber (13) for expanding the expandable chamber (13) from a non-pressurized state to an expanded, pressurised state. The blade (11) is adapted to be slidably mounted with respect to the marine (hull1), with the blade (11) extending laterally along or adjacent to the hull running surface (2), such that expansion of the chamber (13) from a non-pressurized state to the expanded, pressurized state slidably displaces the blades (11) from retracted position above the running surface (2) to an extended position with the blade lower edge (11a) protruding below the running surface (2).</p> |
