EMS Furling Main is an in-mast furling mainsail with long vertical battens making a positive roach possible. The performance almost equals that of a conventional mainsail, whereas the convenience is surpassed.
The long vertical battens with a round profile can be rolled into the mast without being distorted or twisted. This also keeps the bulk of the battens in the mast as small as possible, but with the maximum stiffness. The upper (leech) part of these battens is constructed in carbon for extra stiffness. The round profile of the battens also allows the sail to roll in and out without any hard edges to catch on the entry to the mast chamber.
The battens are joined to make it as easy as possible to get the battens into the sails, and to be stored when the boat is ashore. The bottom end of the batten has an in-built adjuster, as well as an adjuster on the batten pocket. The joints and adjuster are in marine grade stainless steel, to a esign unique to Elvstrom Sails.
Available in woven polyester, DC laminates or EPEX. (tjek tekst)
