About the Gk 24 Westerly Sailboat

Built by respected British yard Westerly Marine from 1976 to 1981, this 24-footer represents solid coastal cruising capability in a compact package. The design collaboration between Laurent Giles and Chris Hawkins produced a well-balanced boat that earned a reputation for seaworthiness and practical accommodation during its five-year production run of 320 hulls. With her fin keel and transom-hung rudder configuration, the GK 24 offers responsive handling while maintaining the shallow draft advantage typical of coastal cruisers. The masthead sloop rig provides straightforward sail handling, making her appealing to both experienced sailors and those transitioning to larger boats. Her substantial displacement of 4,100 pounds, combined with 1,400 pounds of ballast, delivers the stability and motion comfort expected from British design philosophy of the era. The boat's comfort ratio of 15.48 suggests she'll provide a relatively easy motion in a seaway, while her capsize screening value indicates good stability characteristics for coastal and near-shore sailing. Built with Westerly's typical fiberglass construction quality, these boats have proven their durability over decades. The GK 24 suits sailors seeking a manageable yet capable coastal cruiser with accommodation for weekend or short-term cruising adventures.
