The foresail furler allows the sail area to be continuously reduced by simply “terzaroling” it along the luff, without moving from the cockpit. The sail is luffed along a special hollow forestay, an extrudate that today is made of two materials, aluminum (the most common but also the heaviest). The extruded is the channel where the sail luff is strung, capable of rotating continuously around a forestay. Two drums attached to the forestay, one near the tack point and one at the masthead, allow it to rotate on itself.
HOW IT WORKS.
Each drum has a fixed part, integral with the boat, and a sector that can rotate continuously. Rotation if it used to be on bearings today is almost always on balls; check the number of guides (orders): the more the better…
