A4 asymmetric spinnaker

The A4 is a high-wind runner designed for downwind courses in demanding conditions, where stability, control, and sail reliability are key. It is a heavier and smaller version of the A2, making it ideal for situations where a medium-wind spinnaker begins to be overloaded and loses its effectiveness.

Thanks to its reinforced construction and smaller A4 area, it remains stable and allows you to sail the yacht confidently even in challenging conditions. It is the ideal choice at speeds above 20 knots, when full-size, lighter spinnakers become too difficult to handle.

The A4 performs particularly well on long stretches with strong winds, maintaining high speeds while minimizing the risk of stalling. It’s a sail that gives the crew confidence and control when conditions start to dictate the pace—indispensable during high-wind ocean races and coastal regattas.
