Abstract
A pole structure comprising two elongated sheet metal or extruded sections (1 and 2) which are joined together by spacers (7) to provide a gap (5) between the adjacent edges of the elongated sections (1 and 2). This structure provides access to the interior and is most suitable for utilization as a mast of a sailing yacht, being lighter in weight than the standard masts yet being as structurally stable and flexible.
