RLG EVO furling system for Gennaker
New furling system for Gennakers (sails with free flying luff ), an evolution of the well-known and patented ROLLGEN system. This new development is characterized by both higher performances in terms of working load and smoothness in movement, and weight decrease by roughly 60%. Such characteristics have been obtained thanks to the use of materials such as Ergal aluminium alloy and 17-4PH steel.
Differently from the previous model, in the new RLG EVO, the tack swivel (fundamental element when furling free flying sails) is independent from the drum. In fact, it is now integral part of the special ROLLGEN stay.
Consequently, drum and halyard swivel may as well be used to furl CODE 0-type sails (sails hoisted on anti-torsion stay), whereas the special stay totally integrates the furling system for free flying sails (Gennakers) which is Bamar ROLLGEN “patent”.
