Design and Construction
Primrose’s brief was a light-displacement cruiser with a very large beam to deliver both stability and maximum accommodation, and the numbers bear this out: roughly 18,150 lbs displacement carried on a 13 ft 4 in beam, with 6,680 lbs of iron ballast. The wide-beamed hull was unusual in Europe at the time, where narrow hulls dominated the market, and it allowed the 39 to feel huge below while still being a manageable 38 ft 6 in on deck with a 32 ft 6 in waterline. Writing in boats.com, reviewers noted the distinctive centre-cockpit layout and wide-beamed hull design as the defining external cues anchor, and the same source credited the extra beam with letting the boat swallow a large crew and their gear for extended cruising.
Rig and Sail Plan
The 39 is a masthead sloop carrying a 300 sq ft mainsail and a 555 sq ft working genoa, with a 295 sq ft working jib also listed. The sail area supports the light-displacement hull’s character as a quick, roomy cruiser rather than a heavy-weather slug. A 47 hp Thornycroft T108 diesel drives a shaft, and across the Moody range of this period those Thornycroft engines were regarded as robust with greater longevity than many contemporaries anchor, a meaningful point for a boat now decades old.
Accommodations
Below decks the leap from the 33 is immediate. The roomy saloon sits forward of the centre cockpit and houses a U-shaped settee that converts to a double berth; opposite are the chart table, galley, and the passage aft. That passage leads below decks to the owner’s cabin, a proper double with much improved headroom over the 33, an en suite heads and shower, dressing table, wardrobe, and stowage lockers. Between the saloon and the forecabin lies an extra cabin with twin bunks, generous standing and stowage space, and its own spacious heads compartment. Forward of the saloon to port is a guest cabin with two berths and a sliding door, while opposite sits a second wc/shower. The fo’c’s’le cabin offers two berths convertible to a double. The overall effect, boats.com observed, is a boat that feels huge and can easily accommodate a full complement aboard anchor.
Lineage and Successor
The 39’s run was short but influential. The Moody 40, launched in late 1978, was based directly on the 39, adopting a revised aft cabin layout for more space and a modified cockpit arrangement before the cut-off of that record. The 39 thus stands as the roomy centrepiece of Primrose’s centre-cockpit Moody generation before Bill Dixon’s later designs took the marque forward.
The Verdict
The Moody 39 is a compact-volume cruiser that punches far above its 38 ft 6 in length for liveaboard and extended-family cruising. Primrose’s wide-beam, light-displacement hull and centre-cockpit plan created a three-cabin layout with en suite owner’s stateroom that was exceptional for its era, and the Thornycroft diesel gives buyers a known-durable drivetrain. The short production run means scarcity, but the 82 built share a coherent, well-resolved design.
Pros
- Exceptionally spacious three-cabin interior with en suite aft owner’s cabin
- Wide-beamed, light-displacement hull unusual for mid-1970s Europe
- Robust Thornycroft diesel with strong longevity record
- Direct, larger development of the proven Moody 33 lineage
Cons
- Only 82 built (1975–1978), so limited availability
- Centre-cockpit configuration may not suit those wanting aft-cockpit access
