The rig includes a fully-battened, 4.5m² mono-film sail with mast pocket,
similar to that of a windsurf sail. Rigged on an epoxy mast, the sail has
been designed with an open leech to give sailors maximum control
and performance in windy conditions. The Cunningham tackle
(6 threads + cleat) associated with the boom vang / boom safety
attachment, allows sailors to trim efficiently the tension of the sail.
