The ‘sails’ of each structure are formed from laminated strips of red oak, shaped over a variety of formers, to give a billowing effect. The two ‘masts’ are made from solid red oak, spindle-moulded to give a cylindrical profile, but with faceted detailing for each sail component to connect into the mast via a series of hand-turned wooden pegs. The 16mm hemp rope has been made by a traditional ropemaker and holds the piece under tension.
