About the Iw 26 Sailboat

Designed by renowned Swedish naval architect Peter Norlin and built by Iw-Varvet beginning in 1971, this 25-footer represents solid Scandinavian craftsmanship from sailing's golden era. The fiberglass construction features a fin keel with rudder on skeg configuration, providing reliable directional stability while maintaining reasonable performance under sail. With a displacement of 4,189 pounds and 1,800 pounds of ballast, the Iw 26 strikes a balance between seaworthiness and sailing ability. The masthead sloop rig carries 238 square feet of sail area, delivering a moderate sail area-to-displacement ratio that favors steady, predictable sailing over raw speed. Her comfort ratio of 18.19 indicates quick motion in waves, typical of boats designed for active sailing rather than heavy cruising. The hull proportions, with a waterline length of 19.33 feet and beam of 8.33 feet, create a relatively narrow profile that enhances sailing performance while the 4.83-foot draft provides good upwind ability. This combination makes the Iw 26 well-suited for coastal cruising and club racing, particularly in areas with moderate weather conditions. The design reflects Peter Norlin's philosophy of creating practical, seaworthy boats that reward active seamanship.
