Allmand 31 Information, Review, Specs

Sailing Performance & Handling

The Allmand 31 is characterized by a heavy-displacement hull and a generous beam of 11 feet 3 inches, which provides significant initial stability. With a displacement of approximately 11,000 pounds and a ballast-to-displacement ratio near 36%, the boat feels "stiff" and predictable in a breeze. However, this stability comes at the cost of light-wind performance. Technical analysis of its Sail Area/Displacement (SA/Disp) ratio, which hovers around 14.5, classifies it firmly as a moderate-to-heavy cruiser rather than a performance-oriented yacht.

In terms of sea-kindliness, the boat’s motion is damped and comfortable, making it an excellent choice for families or less-experienced sailors who may be intimidated by the "twitchy" nature of lighter fin-keel designs. The shoal draft version, drawing only 4 feet, is the most common configuration found on the used market. While this allows access to thin-water anchorages, owner anecdotes and historical reviews from Practical Sailor note that the boat does not point particularly high into the wind. Its tracking is reliable, though it requires a fair amount of canvas to maintain momentum in anything under 10 knots of true wind.

Interior Comfort & Variations

The defining feature of the Allmand 31 is undoubtedly its "tri-cabin" layout, a design feat that was virtually unheard of for a 31-foot monohull in the late 1970s. By utilizing the wide beam and a clever use of space near the companionway, Walter Scott managed to squeeze in a private aft cabin—often referred to as the "owner's stateroom"—separate from the main salon and the forward V-berth. This configuration offers three distinct sleeping areas, making it a favorite for couples cruising with children or guests.

The interior boasts an impressive 6 feet 4 inches of headroom in the main salon, a specification that outperformed many of its larger contemporaries like the Pearson 32 or the Catalina 30. Allmand utilized a mix of fiberglass liners and teak trim to keep the cabin bright while maintaining a traditional feel. Variations of the model include the standard sloop rig and a less common tall-mast version designed for lighter air regions. The galley is typically U-shaped and positioned to starboard, providing a secure location for food preparation while underway. The 31's sibling, the Allmand 35, followed a similar design philosophy but offered even greater displacement and storage for long-range voyaging.

Known Issues & Buyer’s Checklist

Prospective buyers of an Allmand 31 should prioritize a thorough inspection of the deck and structural components. Like many Florida-built boats of the era, the deck utilizes a balsa core which is susceptible to moisture intrusion and rot if hardware—such as stanchion bases or the windlass—was not properly re-bedded over the decades. Soft spots on the side decks are a frequent "gotcha" for this model.

The aluminum fuel tanks are another critical inspection point; as these boats approach the 40-year mark, original tanks are often nearing the end of their lifespan due to exterior corrosion from sitting in bilge water. Additionally, the rudder post and bearings should be checked for play, as the heavy displacement of the hull puts significant stress on the steering system in heavy weather. Finally, because Allmand used a variety of engine suppliers, including Universal and Yanmar, buyers should verify the parts availability for the specific diesel plant installed in the hull they are considering.

Community & Resources

While there is no longer a formal manufacturer support system, the Allmand 31 maintains a dedicated following. Owners often congregate on platforms like the Allmand Boats Facebook group or specialized threads on CruisersForum to share technical advice on the unique "tri-cabin" plumbing and electrical runs. These communities are vital for sourcing replacement parts that may be specific to Walter Scott's custom hardware choices.

The Verdict

The Allmand 31 remains one of the most spacious 31-footers ever built, offering the interior privacy of a 36-foot vessel without the associated dockage fees. It is a purpose-built coastal cruiser that sacrifices racing speed for comfort and shallow-water utility.

Pros:

• Revolutionary tri-cabin layout provides exceptional privacy for its size.
• Excellent headroom (6'4") caters well to taller sailors.
• Shoal draft makes it an ideal candidate for Florida, the Bahamas, and the Chesapeake Bay.
• Heavy, sturdy construction provides a safe, stable platform in choppy coastal waters.

Cons:

• Sub-par upwind performance due to the shoal keel and heavy displacement.
• Aging balsa-cored decks require diligent maintenance to avoid expensive delamination.
• Sluggish performance in light air (under 10 knots).
