Harken Air winches feature a set of interchangeable gearing kits that give skippers the flexibility to create a perfect blend of speed and power for each day’s weather and crew configuration. The winches, which feature a nearly empty middle to reduce weight, were designed for trimming sails on AC foiling cats, IMOCA 60s, AC75s, TP52s and similar Grand Prix boats. The hollow middle is a first for sailing winches, as are the changeable gear kits. All Harken Air winch models feature interchangeable first-speed and second-speed options. The wide-diameter drums allow fewer wraps, faster trimming, and faster easing. Standard and counter-rotating versions are available. The 900 model is designed for boats over 24.4 m (80'). The 900 drum is made of carbon fiber and anodized aluminum.
