This illustration does little visual justice to the end product, a 6 (7 meter measured from floor) tall mast with cross forms near the top, made from steel (originally aluminium, see below) and cleverly painted to look like wood. Hydraulics drive the mast from horizontal deck resting to the vertical. Like the wheelhouse, the mast hydraulics will assist in quickly lowering the mast when negotiating low bridges etc. Hydraulic motors drive the cable winch and the base turntable, allowing ease of pivoting the loaded mast with RIB or 'bike' from bow store to quayside or waterside. The mast design is of the GAFF style and reminiscent of the 1800's rigging design where the sail has a squared off top section, reducing its height but offering more sq meters of sail area in its main cloth. The GAFF arm is made of steel and the boom of aluminium. The reason for this differing materials is one of strength and wear-n-tear. The boom will undergo regular man-handling transfer from mast to deck as it is discarded when not sailing and when the mast turns into a hoist. |
