OneSails presents the IFS™ (Integrated Furling System), a new style of headsail and downwind sail construction which uses continuous fibre technology to create sails which can be furled without the use of a heavy and expensive anti-torsion cable. IFS™ sails are designed to incorporate a net of continuous structural fibres, laid directly on to the sail’s luff, effectively replacing the cable. The advantages of this technology are considerable. A wider range of sail shapes can be set and furled with sail handling eased by the reduction in weight. Thanks to the lower halyard tensions needed, 30% - 35% less than used with anti-torsion cable, it’s possible to avoid the need for a 2:1 halyard, reducing the sprit load and improving safety.
The IFS™ is a new sail concept with important advantages noticeable both when racing and cruising. Improved aerodynamic performance. Structure integrated within the sail which allows furling without an anti-torsion cable. Lower halyard tension by 35% when compared to a traditional sail with cable. Without a cable the sail’s luff can be designed to project forward and to windward, improving performance at wider angles. Easy to handle because the furled sail is light and can easily be folded to fit in its bag. Stable leech profile even if measured as a gennaker according to ORC and IRC rules. Lighter sail (without anti-torsion cable). Bespoke finishing and accessories.
