The National 10 (Turnabout) is a venerable small sailing dinghy with a rich history as a training vessel and club racer. Designed by Harold R. Turner in 1953, this monohull features a centerboard and a simple cat rig, making it accessible for new sailors and a popular choice for junior programs and frostbiting fleets. While originally known as the Turnabout Class, it formally adopted the name National 10 in 1972, with JG Marine emerging as a key builder in its later production years, upholding the boat's one-design principles.

The National 10 began its journey in 1953 as the Turnabout Class, conceived by Harold R. Turner. It was initially designed as a small wooden single or double-handed junior training dinghy, with many units completed by "do-it-yourselfers" from kits. In 1972, the Turnabout Class officially changed its name to the "National 10" class. This transition also involved a refinement of the class, approving a new mold that adhered closely to the original wooden design while incorporating improvements such as aluminum spars. The minimum class weight was also increased from 215 lbs to 255 lbs to maintain competitive balance between the older wooden boats and the newer fiberglass iterations. Builders like Parker River Marine and J.R. Duplin Marine were instrumental in its early production, with JG Marine later continuing its legacy, emphasizing consistent, high-quality construction aligned with the strict one-design specifications to ensure fair racing.

Sailing Performance and Handling

With a length overall of 9.67 feet and a reported sail area of 61 square feet, the National 10 is designed for simplicity and ease of handling, characteristic of a training dinghy. Its cat rig, featuring a main sail, contributes to straightforward rigging and sailing. Anecdotal evidence from owners suggests the National 10 is a stable and forgiving boat, making it an excellent platform for learning the fundamentals of sailing and racing. Its centerboard configuration allows for flexible sailing in varying depths and contributes to its upwind performance when lowered, while providing the ability to reduce draft for beaching or shallow waters when raised. Owners often praise its suitability for family outings and its ability to handle choppy conditions on lakes.

Accommodations and Layout

Given its compact size as a 9-foot, 8-inch dinghy, the National 10 does not feature enclosed interior accommodations in the traditional sense. Instead, its layout is focused on an open cockpit designed to maximize space for a single sailor or a small crew, typically two people. The design prioritizes functional, open space for sailing maneuvers and comfort during short excursions or races. The robust fiberglass hull, typical of later models, provides a durable and low-maintenance structure.

Owner's Perspectives

Owners of the National 10 consistently appreciate its solid construction and durability, often highlighting its suitability for junior sailing programs and club racing. The boat's simple design and stability are frequently cited as key strengths, making it an ideal choice for new sailors. While not widely detailed in terms of common problems due to its robust and straightforward design, any issues tend to relate to general wear and tear typical of a small, frequently used dinghy. Its longevity and the active class community demonstrate a strong owner satisfaction and a commitment to preserving this enduring training vessel.
