Sailing downwind can feel settled once a boat is correctly trimmed, but large sails are not always straightforward to set and recover with a small crew. OneSails has published further guidance on its IFS Multi Tradewind Sail, a twin-sail arrangement that revisits the wing-on-wing concept using an integrated furling structure.
The approach is intended to combine balanced running with simpler handling than some conventional large downwind sails. It is an equipment-development story rather than a guarantee that the system suits every rig.
Twin sails on opposite sides
The concept sets two symmetrical panels to work on opposite sides of the boat, presenting sail area on a broad run. That can give cruising sailors a different way to use following wind without relying entirely on a conventional spinnaker.
The correct trim and suitable apparent-wind range remain important. A sailor should use the manufacturer guidance and the vessel's own stability and rig limits.
What the structure changes
OneSails' Integrated Furling Structure brings load-bearing elements into the sail design, seeking a more controlled hoist and recovery process. Furling features are particularly interesting for short-handed cruising crews.
Good line leads, enough deck space and crew practice still determine whether an operation is safe. A mechanism does not remove the risks of loaded running rigging.
A small-boat perspective
For an under-12-metre cruiser, the relevant question is whether the chosen size and hardware match its rig and crew. Installation needs approval from the sailmaker and an appropriate assessment of attachment points.
