Our furling profiles are initially designed to carry out a proper furling of the sail along its base and to guarantee its reliability in use. In contrast to other systems, furling in the boom allows the sailmaker to design a high-performance joint sail thanks to the possibility of using high-tech materials such as laminates and aramid fibre membranes. In addition, their battens make it possible to obtain very tapered sails by significantly increasing the surface area in the high-performance part of the sail. It is also possible to design semi-squaretop sails, thus offering modern and elegant sail plans. modern and elegant sail plans. The particularity of furling mainsails also lies in their reinforcements in the reefing areas, thus allowing excellent sailing even in strong wind conditions with a reduced mainsail, considerably increasing the range of use.
