Abstract

A sailing crane system (1, l1) comprises: a column (10) comprising a base (20) and a body (30); a sail boom (50) coupled to the base (20); a load-bearing boom (70, 70') extending between a proximal end (71, 71') and a distal end (72, 72'), wherein the proximal end (71, 71') of the load-bearing boom (70, 70') is rotatably coupled to the body (30), the load-bearing boom (70, 70') being configured to rotate between: i) a stowed boom configuration in which a longitudinal axis (L) of the load-bearing boom (70, 70') is aligned with a longitudinal axis (X) of the column (10); and ii) a load-bearing configuration. A method of operating the sailing crane system (1, l1) comprises rotating the load-bearing boom (70, 70') from the stowed boom configuration to the load-bearing configuration; and/or rotating the load-bearing boom (70, 70') from the load-bearing configuration to the stowed boom configuration.
