Hot Sails Maui Kauli Seadi 3 Batten XLightThe KS3 is powerful yet unbelievably stable as the three batten design has radically less sail momentum which leads to faster response times and improved feel. The result is a more explosive wave ride and quicker action in the air. The result for those not wave sailing is an amazing new type of sail that seemingly does not get overpowered and maintains a locked in feel under all wind conditions.
