Shannon 39 Information, Review, Specs

Sailing Performance & Handling

The Shannon 39 is defined by its sea-kindly motion and exceptional tracking, traits inherent to its hull shape. It features a modified full keel with a cutaway forefoot and a protected skeg-hung rudder. This configuration provides the directional stability required for long offshore passages while remaining significantly more maneuverable in tight marinas than a traditional full-keel vessel. With a displacement-to-length (D/L) ratio typically falling in the "heavy cruiser" category, the 39 does not "bounce" over waves; rather, it powers through them, maintaining momentum in a seaway.

One of the most distinctive aspects of the 39’s performance is the available "Scutter" rig—a proprietary Shannon innovation that combines the benefits of a sloop and a cutter. This rig utilizes two non-overlapping headsails: a large reacher/genoa for light air and a smaller working jib for heavier conditions, both mounted on furlers. Editorial testing by Cruising World has historically praised this setup for its versatility, allowing sailors to adjust the sail area from the safety of the cockpit as wind speeds increase. While not a light-air racer, the 39 finds its stride in 15 to 25 knots of breeze, where its stiff stability and balanced helm allow it to eat up offshore miles with minimal stress on the autopilot or wind vane.

Interior Comfort & Variations

Inside, the Shannon 39 is a masterclass in New England cabinetry. The interior is characterized by extensive use of hand-varnished teak or cherry and a teak-and-holly sole. Unlike mass-produced boats that rely on fiberglass liners, the 39’s furniture is often tabbed directly to the hull, contributing to the vessel’s structural rigidity. The standard layout features a forward V-berth (or sometimes a Pullman berth), a comfortable main saloon with a drop-leaf table, and a well-appointed galley to starboard.

Because Shannon is a semi-custom builder, variations are common. Some hulls were outfitted with a dedicated navigation station that rivals those found on 50-footers, while others prioritized a larger head with a separate stall shower. Headroom is generous, typically exceeding 6’4”, a feat achieved without making the coachroof appear overly bulky from the exterior. The 39 shares much of its interior DNA with its larger sibling, the Shannon 43, though it manages to feel remarkably spacious for a sub-40-foot boat by utilizing every nook for dry storage—a necessity for the "liveaboard" mission for which it was designed.

Popular Mentions & Media

The Shannon 39 has long been a darling of the yachting press, frequently appearing on "best used boat" lists for prospective circumnavigators. It gained significant attention during its launch for being one of the first high-end cruising boats to successfully implement vacuum infusion on a large scale. The model is also featured in various blue-water cruising guides as a benchmark for "over-built" American craftsmanship. While it may not have the YouTube presence of modern carbon-fiber flyers, it remains a staple in the logs of the Seven Seas Cruising Association.

Known Issues & Buyer’s Checklist

Purchasing a Shannon 39 requires a keen eye for systems maintenance rather than structural failure, as the hulls are notoriously robust. However, prospective buyers should focus on the following:

1. Chainplate Inspection: Like any boat designed for offshore work, the stainless steel chainplates should be inspected for crevice corrosion, especially where they pass through the deck.
2. SCRIMP Hull Condition: While the infusion process produces a superior laminate, a marine surveyor should verify that no aftermarket thru-hulls were improperly sealed, which could lead to moisture entering the core.
3. Teak Deck Wear: Many Shannon 39s were commissioned with traditional teak decks. On older hulls, check the thickness of the wood and the condition of the caulking, as a full deck replacement is a significant capital expense.
4. Standing Rigging: Given that these boats are often used for transoceanic voyages, the age of the standing rigging is a critical safety factor. Most insurers require replacement every 10–12 years regardless of visual appearance.

Community & Resources

Owners of the 39 benefit from the "Shannon Family" atmosphere cultivated by the shipyard. The Shannon Yachts company maintains a high level of involvement with their legacy fleet, often assisting second or third owners with original blueprints and technical advice. The most prominent hub for technical exchange is the Shannon Owners Group, an informal but highly knowledgeable network of sailors who share specific maintenance tips on everything from rudder bearing replacement to optimizes sail trim for the Scutter rig.

The Verdict

The Shannon 39 is a connoisseur's yacht, built for the sailor who values safety and longevity over the latest Mediterranean styling trends. It is a vessel that looks as "right" in a Maine harbor today as it did thirty years ago.

Pros:

• Exemplary build quality and "old-world" joinery.
• The Scutter rig offers exceptional versatility for short-handed crews.
• Superior heavy-weather handling and motion comfort.
• High resale value due to the brand’s prestigious reputation.

Cons:

• High initial and secondary market price point.
• Traditional heavy displacement makes for slower speeds in light air.
• Teak-intensive exteriors require significant maintenance to keep in Bristol condition.
