The Sq 25 combines sportboat characteristics with practical cruising capabilities, making it an appealing choice for sailors seeking both excitement and comfort in a trailerable package. Built by Sq Yachts using GRP construction, the design features a distinctive fin keel with bulb and transom-hung rudder configuration that delivers impressive sailing performance. The fractional sloop rig provides excellent sail handling characteristics, while the generous sail area of 376.74 square feet and substantial SA/Displacement ratio of 26.08 indicate this boat was designed to move efficiently in light to moderate conditions.
