Design and Construction
The Moody 31 Mk I measures 30 feet 9 inches overall, with a 26-foot waterline and a beam of 10.5 feet. Displacement is near 9,921 pounds, including 3,527 pounds of ballast, for a ballast-to-displacement ratio close to 36 percent.
The hull is solid fiberglass with thick laminates, and the deck is likewise solid. Below, the joinery is teak. The boat has a modern fin keel, with a twin-bilge-keel version available as an option. Both are paired with a skeg-hung rudder, providing balanced handling and protection.
Rig and Handling
The masthead sloop rig keeps sail management straightforward while delivering good all-around performance. Its sail plan is modest but versatile. The mainsail is roughly 199 square feet, with a 33.5-foot luff. A 115-percent jib measures near 233 square feet, while the 150-percent genoa is about 361 square feet.
For sailing off the wind, the inventory extends to a drifter of similar area and a 595-square-foot asymmetrical spinnaker. A conventional spinnaker reaches 736 square feet, while a 60-percent storm jib provides 83 square feet for heavy air.
Together, the skeg-hung rudder and the choice of fin or bilge keels make the boat predictable in close quarters and forgiving for a cruising couple or family.
Accommodations
For a boat of this length, the Moody 31 has a spacious and practical interior. It sleeps six across a forward V-berth, the saloon settees, and an aft cabin. There’s also a galley and an enclosed head.
The layout earned praise for its excellent headroom and storage, both unusual in a boat of this size. Solid teak joinery gives the cabin a durable, settled feel rather than the character of a lightweight production finish.
Machinery and Ownership
Auxiliary power comes from a 28-horsepower Volvo Penta MD2003 diesel with shaft drive. It’s a straightforward unit to service, while the simple masthead rig makes the running rigging and sail inventory easy to maintain or renew.
The Moody 31 Mk I belongs to a small, clearly defined production run of 259 boats. Its reputation as a comfortable, seaworthy 30-footer of its era supports steady interest, although production lasted only from 1983 to 1987 and the design didn’t continue as a direct line under later Moody generations.
The thick hull laminates and solid teak joinery point to conservative construction, but each used example should still be surveyed on its own merits.
The Verdict
The Moody 31 Mk I is a Dixon-designed British cruiser that punches above its 30-foot length, thanks to conservative construction and a genuinely roomy interior. For a couple or small family looking for a well-built 1980s cruiser with a forgiving helm and practical accommodations, it remains a considered choice.
