Moody 336 Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Moody 336 are defined by its high-aspect fractional rig and a hull shape that prioritizes speed over the sheer volume seen in earlier center-cockpit designs. Unlike the earlier Moody 33, which relied on its weight for stability, the 336 uses a more balanced approach. According to an editorial review by Yachting Monthly, the boat is surprisingly nimble, capable of pointing high and maintaining momentum in light airs, yet it remains stiff and predictable when the wind climbs toward 20 knots.

The 336 was offered with both a deep fin keel and a twin-keel (bilge keel) configuration. While the fin keel provides superior lift and pointing ability, the twin-keel version was highly popular in the UK and Northern Europe for its ability to dry out in tidal harbors. Despite the added drag of the twin keels, the Dixon-designed hull retains enough efficiency to remain competitive in club racing. The helm is typically reported as light and responsive, thanks to a well-balanced spade rudder, which allows for effortless handling even when the boat is pressed under full sail.

Interior Comfort & Variations

For a 33-foot yacht, the interior of the Moody 336 is often described as "Tardis-like" due to its clever use of beam and the strategic placement of the engine. The layout is centered around a traditional saloon with a folding central table and straight settees that double as sea berths. The joinery is predominantly teak-faced plywood with solid teak trims, reflecting a level of craftsmanship higher than many contemporary mass-market competitors.

The standout feature of the 336 is the aft cabin. By utilizing the full beam of the stern, Bill Dixon created a master suite with a massive transverse double berth, a private settee, and ample hanging locker space—a luxury rarely found on yachts of this size in the late 80s. The forward V-berth provides a secondary private cabin, making the boat ideal for two couples or a small family. The L-shaped galley is located to starboard, featuring a twin-burner stove, oven, and deep refrigerated icebox. While the interior remained largely consistent throughout its production, minor variations in upholstery and the transition from the Thornycroft T80 to Volvo Penta engines are common among used models.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Moody 336 with a focused checklist, primarily targeting age-related maintenance and specific construction choices of the late 20th century.

• Deck Core Integrity: Like many yachts of this era, the 336 features a balsa-cored deck. Buyers should check for "soft spots" or delamination, particularly around stanchion bases, cleats, and the windlass, where water ingress can rot the core.
• Engine Service History: Many original 336s were fitted with the Thornycroft T80 (based on the Mitsubishi block). While reliable, parts for the Thornycroft marinization components (like the heat exchanger) can be harder to source than those for the later Volvo Penta 2000 series or modern Beta/Yanmar replacements.
• Rudder Bearings: The spade rudder is a performance asset, but the bearings are prone to wear. Excessive play at the helm or a "clunking" sound while underway often indicates that the top or bottom bearings require replacement.
• Headlining Sag: The foam-backed vinyl headlining used in the cabins is notorious for failing over time as the foam degrades. If the lining is sagging or "dusty," a labor-intensive replacement is likely necessary.
• Keel Bolts: Particularly on twin-keel versions, the stresses on the keel-to-hull joint should be inspected for signs of movement or "smiles" in the sealant, which may necessitate re-torquing or replacing the bolts.

Community & Resources

Owners and prospective buyers have access to a wealth of technical data through the Moody Owners Association. This organization maintains an extensive archive of original brochures, wiring diagrams, and a technical library that is considered one of the most comprehensive for any production yacht brand. The association also organizes regional rallies and provides a forum where the specific nuances of the 336 are discussed by long-term owners.

The Verdict

The Moody 336 remains a top-tier choice for sailors seeking a balanced cruiser that doesn't sacrifice sailing pleasure for dockside comfort. It bridges the gap between the "heavy" cruisers of the 70s and the "light" cruisers of the modern era.

Pros:

• Exceptional Aft Cabin: One of the best master cabins in the 30–35 foot class.
• Balanced Performance: Capable of offshore passages while remaining fun to sail in coastal breezes.
• Build Quality: Solid GRP layup and high-quality interior joinery that stands the test of time.

Cons:

• Aging Systems: Original engines and electronics are often at the end of their service life.
• Headlining Issues: The common "Moody sag" in the cabin overheads is a messy and expensive fix.
• Galley Size: While functional, the galley is compact compared to more modern, beamier designs.
