The Moody 346 is a robust, center-cockpit cruising yacht that represents a high-water mark for A.H. Moody & Sons during the late 1980s. Designed by Bill Dixon and introduced in 1986, the 346 was an evolution of the earlier Moody 34, sharing the same hull but incorporating a refined "sugar scoop" transom and improved interior ergonomics. Over its four-year production run ending in 1990, the model became a benchmark for the "liveaboard 34-footer," offering a level of privacy and offshore security usually reserved for vessels exceeding 40 feet. It was built with the high-quality GRP (Glass Reinforced Plastic) standards that defined the yard’s reputation, ensuring that many remain in active service as reliable coastal and blue-water cruisers today.

Sailing Performance & Handling
The Moody 346 is characterized by its stiff, predictable motion and "sea-kindly" behavior, a result of its moderate displacement and well-balanced hull. With a displacement-to-length ratio that leans toward heavy-cruising stability, the 346 is not a light-wind racer but excels when the breeze freshens. According to an editorial review by Yachting Monthly, the yacht is remarkably easy to handle under power, though its high topsides and center-cockpit windage require a confident hand when maneuvering in tight marinas during a crosswind.
The boat was offered in both fin keel and twin (bilge) keel configurations. The fin keel version offers superior upwind tracking and reduced leeway, while the twin keel variant—highly popular in the UK and Northern Europe—allows the boat to dry out in tidal harbors. In terms of sail plan, most 346s were rigged as masthead sloops with furling headsails. The center cockpit provides an exceptionally high and dry vantage point for the helm, which enhances the sense of security when navigating through heavy chop or inclement weather.
Interior Comfort & Variations
The primary appeal of the Moody 346 lies in its interior volume, particularly the aft cabin. Unlike many 34-footers of its era that utilize a cramped aft quarter-berth, the 346 features a dedicated owner’s stateroom aft. In the 346, this cabin is accessed via a walkthrough corridor from the main saloon, a significant upgrade over the original Moody 34, which often required crossing the cockpit to reach the aft quarters. This walkthrough typically houses the engine access and, in many layouts, a dedicated navigation station or additional storage.
The main saloon features a traditional U-shaped settee to port and a straight settee to starboard, flanking a central folding table. The use of warm teak joinery and high-quality upholstery was a Moody hallmark, creating a cabin environment that feels substantial and durable. Headroom is generous throughout, often exceeding six feet even in the walkthrough. The 346 also features a forward V-berth and a well-appointed heads compartment, making it a true two-cabin, two-head (in some custom variants) or high-volume single-head cruiser. Its sibling, the Moody 34, utilizes an aft-cockpit layout which provides a larger cockpit but sacrifices the expansive, private aft-cabin experience that defines the 346.
Known Issues & Buyer’s Checklist
Prospective buyers should approach the Moody 346 with a focus on its age-related maintenance, as most units are now approaching or exceeding four decades of service.
- Deck-to-Hull Joint and Windows: Like many Moodys of this vintage, the aluminum-framed windows can develop leaks over time, which may damage the interior woodwork. Similarly, the deck-to-hull joint should be inspected for weeping, especially around the toe rail.
- Engine Service: Many 346s were originally fitted with Thornycroft T80 or Volvo Penta engines. While reliable, these may be reaching the end of their service life. Buyers should check for heat exchanger corrosion and ensure that the sail drive seal (if equipped) or shaft gland is well-maintained.
- Headlining Sag: A common issue in British-built yachts of the 80s is the degradation of the foam backing on the vinyl headlining. If the headlining is sagging or "baggy," it often indicates the foam has turned to dust, a labor-intensive but common repair.
- Osmosis: While Moody used high-quality resins, any GRP hull from the late 1980s should be checked for osmotic blistering. Practical Boat Owner notes that while the hulls are generally thick and robust, a moisture meter test during survey is essential.
Community & Resources
Owners of the 346 benefit from one of the most robust owner associations in the sailing world. The Moody Owners Association provides an extensive technical library, including original brochures, wiring diagrams, and a "Technical Information Exchange" where decades of owner-led solutions for specific 346 problems are archived. This community is a vital resource for sourcing replacement parts that are no longer in production.
The Verdict
The Moody 346 remains a premier choice for couples or small families seeking a safe, comfortable, and well-built cruiser that punches well above its weight class in terms of interior accommodation.
Pros:
- Exceptional aft cabin privacy for a 34-foot yacht.
- Solid, offshore-capable construction and predictable handling.
- Strong resale value and an active, supportive owner association.
- Versatile keel options (fin or twin) for different cruising grounds.
Cons:
- Center-cockpit design leads to higher windage when docking.
- Dated interior headlinings and window seals often require replacement.
- Not a high-performance boat in light air or competitive racing scenarios.
