OneSails Cruising Symmetric and Asymmetric Spinnakers

The Downwind cruise sails by Onesails are designed for a safe and easy navigation even with a short handed crew. All the designs are developed with CFD simulation because the first aim of OneSails that is Quality and attention at all the details. The materials used are the best and selected to work properly under load, in a way to offer the best solutions to any customer. The Spinnaker and the Gennaker by OneSails can be provided with a special bag, the sock or a special furling system studied to simplify the dip.


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.

  1. Improved aerodynamic performance.
  2. Structure integrated within the sail which allows furling without an anti-torsion cable.
  3. Lower halyard tension by 35% when compared to a traditional sail with cable.
  4. Without a cable the sail’s luff can be designed to project forward and to windward, improving performance at wider angles.
  5. Easy to handle because the furled sail is light and can easily be folded to fit in its bag.
  6. Stable leech profile even if measured as a gennaker according to ORC and IRC rules.
  7. Lighter sail (without anti-torsion cable).
  8. Bespoke finishing and accessories.

The spinnaker is an important sail for cruising and OneSails provide the experience of designers and sailors, giving the perfect equilibrium between the surface and wind range angles. The spinnaker becomes, in this way, a real enjoyable moment for the whole crew and they can sail downwind without stress.

The gennakers by OneSails are designed for a wide range of apparent wind angle to avoid a continuous trimming during sailing. The Sails are controlled with fluid dynamic software simulations and optimized with the boat dimensions to get easy hoist and dip.
