The Allied 39, produced by the esteemed Allied Boat Company from 1970 to 1973, is a robust offshore cruiser known for its solid construction and seaworthy design. Conceived from an earlier design and significantly re-engineered by Robert Harris, this masthead sloop (also available as a yawl) embodies Allied's commitment to building capable and dependable fiberglass yachts. She was designed for comfortable cruising and stands as a testament to the company's reputation for quality in the early 1970s.

The Allied 39's lineage traces back to the wooden Owens Cutter, with its fiberglass iteration first appearing as the Borsaw 40. Allied Boat Company acquired these molds, and under the naval architecture of Robert Harris, the design underwent significant modernization. Harris transformed the traditional transom to a reverse transom, updated the underbody with a more contemporary fin keel, and added slightly more beam. This redesign aimed to enhance performance and handling while retaining the robust characteristics Allied was known for. Built for serious cruising, the design prioritizes reassuring stability and a generous sail plan to deliver good light-air performance.

Allied Boat Company, established in 1962, quickly gained a reputation for robust construction and a strong warranty. During the Allied 39's production run from 1970 to 1973, the company upheld its ethos of building solid, offshore-capable fiberglass sailboats. The Allied 39, with its fiberglass solid hull and deck construction, exemplifies this commitment to durability.

Sailing Performance and Handling

With a calculated sail area to displacement ratio of approximately 16.4, the Allied 39 is categorized as a moderately powered cruiser. This suggests a boat that performs competently across a range of wind conditions, offering a good balance between light-air performance and the ability to carry sail in stronger breezes without being overly tender. The generous sail plan is specifically noted for its excellent light-air performance.

The ballast to displacement ratio of around 0.394 indicates a boat with good initial stability, allowing her to stand up well to her canvas. Coupled with a displacement to length ratio of approximately 316, the Allied 39 falls into the category of a heavier displacement cruiser. This heavy displacement, combined with her fin keel and skeg-hung rudder, implies a comfortable motion in a seaway, making her well-suited for extended cruising and offshore passages. She is designed to offer reassuring stability in all conditions.

Accommodations and Layout

While specific interior layouts for the Allied 39 are not widely detailed in general specifications, boats of this size and era from Allied Boat Company were typically designed for comfortable cruising. The company's reputation for solid construction would have extended to the interior, with robust joinery and functional layouts. Accommodations generally featured standard layouts for a monohull of nearly 40 feet, prioritizing practicality and seaworthiness for extended voyages. Water capacity is 100 gallons and fuel capacity is 30 gallons, supporting a self-sufficient cruising lifestyle.
