J/109 A4-1 Asymmetric
Wind range: 18+ knots
The A4-1 Asymmetric isn’t just a heavier version of the A2, its shape and geometry are optimized for sailing in breeze over 18 knots TWS. The A4-1 Asymmetric is more stable and easier to trim and gybe in heavier breeze. It is designed to keep the tack down while still projecting out to windward, which makes it easier to keep the boat under the chute even in lumpy conditions. A great addition to any J/109 inventory.
