Moody 31 Mk I Information, Review, Specs

History and Design

The Moody 31 Mk I entered production in 1983 and was built until 1985, a period during which Moody Yachts, then A. H. Moody & Sons, was firmly established as a leading builder of GRP (Glass Reinforced Plastic) cruising yachts. The design was entrusted to Bill Dixon, a prominent naval architect who would contribute significantly to Moody's fiberglass era, shaping many of their successful aft cockpit and center cockpit cruisers throughout the 1980s and 1990s. Dixon's philosophy, aligned with Moody's core values, focused on creating vessels that offered ample volume, comfort, and dependable sailing performance.

During this era, Moody maintained a strong reputation for construction quality, moving from traditional timber to modern GRP, which allowed for increased production efficiency while upholding their commitment to durability. The company's manufacturing ethos emphasized building yachts capable of handling challenging sea conditions, appealing to cruising sailors who valued offshore capability and liveability.

A notable variation during its production run was the availability of a bilge keel version, offering a shallower draft of 3.67 feet compared to the standard fin keel's 5.0 feet. This option provided greater flexibility for accessing shallower anchorages and drying out. The Mk I is distinct from its successor, the Moody 31 Mk II, primarily by its flat transom, whereas the Mk II features a small sugarscoop boarding platform.

Sailing Performance and Handling

The Moody 31 Mk I, with its specifications, presents a profile of a moderate displacement cruiser. Its Sail Area to Displacement ratio (SA/D) of approximately 14.76 suggests a boat that will perform adequately in moderate to strong breezes but may require more wind to get moving swiftly in lighter conditions. The Ballast to Displacement ratio (Ballast/Disp) of around 0.37 indicates a reasonable degree of stiffness, allowing the boat to stand up to its canvas well in a blow, contributing to a comfortable and stable ride.

With a Displacement to Length (D/L) ratio of approximately 271, the Moody 31 Mk I falls into the category of a moderate to heavy displacement cruiser. This translates to a solid feel and a comfortable motion, particularly in a seaway, rather than a light, agile, or overtly performance-oriented vessel. Owners frequently praise the Moody 31 for its excellent sailing qualities and good seakeeping abilities. It is often described as a solid, capable, and surprisingly fast boat for its type, offering ease of handling, even for single-handed sailing. The skeg-hung rudder also contributes to good directional stability.

Accommodations and Layout

Despite its modest length, the Moody 31 Mk I is renowned for offering surprisingly spacious and well-appointed accommodations, making it a popular choice for couples and families. The interior typically features a traditional layout designed for comfortable cruising.

Forward, there is generally a V-berth cabin, providing sleeping for two. Aft of this, the main salon typically includes settees on both sides, often convertible to berths, surrounding a central table. The galley is usually located along one side, equipped with essential cooking facilities, while the navigation station often occupies the opposite side. One of the distinguishing features highlighted by owners is a good-sized aft double cabin, providing a private and comfortable sleeping area. The head (bathroom) is typically located to one side, offering adequate space and facilities.

Owners report that the Moody 31 offers excellent accommodation and is roomy, with sufficient headroom for most individuals, even those around 6'4". The overall finish quality generally reflects Moody's commitment to traditional joinery and robust materials, offering a warm and inviting interior. Storage is typically ample for a boat of this size, and good ventilation is provided through deck hatches and portlights.

Owner's Perspectives

Owners of the Moody 31 Mk I consistently express high satisfaction with the boat's solid construction and its ability to handle various sea conditions with comfort. Many consider it an ideal first yacht or a capable vessel for long-term cruising, praising its ease of handling, even for those sailing single-handed or with limited crew. The generous interior volume, particularly the aft cabin, is a frequently lauded strength, providing comfortable living spaces for extended periods aboard. The boat is often described as capable and surprisingly fast for a cruising yacht, offering a good balance of performance and comfort.

While generally well-regarded, some common points of discussion among owners include potential issues with corrosion at the base of steel components, which is a consideration for older vessels. As with any boat of its age, original deck fittings may develop leaks over time, necessitating re-bedding. However, the strong community of Moody owners worldwide indicates a collective appreciation for these enduring yachts, with many owners expressing their enduring love for the model and its suitability for comfortable cruising.
