About the Islands 19 Sailboat

Built by Sumner Boat Co. from 1980 to 1994, this compact fractional sloop represents an excellent entry point into trailerable sailing and coastal cruising. With her swing keel design, the Islands 19 offers remarkable versatility, drawing just 3.75 feet when deployed for sailing performance, yet capable of shallow-water exploration and easy launching from boat ramps when retracted. The fiberglass construction and conservative proportions create a stable, forgiving platform ideal for beginning sailors and small family outings. Her generous beam of 7.58 feet provides surprising interior volume for weekend camping aboard, while the relatively light 950-pound displacement keeps her easily manageable on a trailer. The 205 square feet of sail area delivers respectable performance without being overwhelming for novice crews. This design excels in protected waters, small lakes, and coastal day sailing where her shoal draft capabilities truly shine. The swing keel configuration allows access to beaches and shallow anchorages that would challenge fixed-keel boats, making her particularly appealing for exploration and camping adventures. While not intended for serious offshore work, the Islands 19 provides solid construction and seaworthy handling characteristics that have earned a loyal following among sailors seeking an affordable, versatile small cruiser.
