Why do some listings show a 1987 start date?

The official production window for the Moody 336 is 1988–1996 (starting December 1988). A 1987 date in a listing is usually a catalogue error copied between databases. Always verify the year on the boat's physical builder's plate.

What are the exact dimensions of the Moody 336?

It measures 10.19m in length and 3.53m in beam, with a displacement of approximately 5.7 tons. If you see figures like 10.21m x 3.42m, you are likely looking at a different model or an incorrect catalog entry.

Could this be a Moody 34, 346, or a Hanse-era model?

No. The 336 is a distinct Dixon/Marine Projects design with an aft cockpit. The 34 and 346 are different hulls, and the Hanse-era Moodys (post-2007 AC/DS lines) come from an entirely different shipyard and era.

What keel options were available?

The 336 was offered with either a fin keel (~1.68m draft) or a twin (bilge) keel (~1.20m draft). The twin keel is rarer but highly valued for drying moorings.

What are the critical points to check regarding moisture?

Pay close attention to the deck seals around the chainplates and the condition of the internal plywood bulkheads. Check the hull for osmosis or history of barrier treatments, noting that bilges were originally finished without topcoat.

Is it a center-cockpit boat like a Hallberg-Rassy 36?

No. The Moody 336 is an aft-cockpit cruiser. It offers a very large aft cabin, but the layout is fundamentally different from the Nordic center-cockpit tradition.

What is the difference between Mk1, Mk2, and the S336?

These variants mainly differ in salon window design, deck hardware, and the engine generation (early Volvo 2003 vs. later MD2030B). The hull remains the same, but maintenance requirements vary.

Is this the same as a Hanse Moody DS?

No. The DS/AC models built after 2007 represent a different era of the brand. While Bill Dixon's name may appear in both histories, the 336 is a classic Marine Projects build.

Moody 336

Name: Moody 336
Brand: Moody
Availability: InStock

You step into the aft cabin of a 10-metre Moody 336 and glance back at the door, half sure you walked into the wrong boat. How did a wide athwartships berth and a proper settee fit here when the deck outside still reads as a 33-footer? Bill Dixon's "TARDIS" packing for Marine Projects put the living volume aft instead of stretching it along the hull, so the cabin feels a size larger than the plate suggests.

On the builder's plate and in checked tables this is the 1988–1996 window: hull about 10.19×3.53 m, about 200 hulls, lightship about 5.7 t. Listings that open with 1987 and 10.21×3.42 are database drift, not this series. The Moody owners archive places introduction in December 1988 and the end around June 1996. This is not a later Hanse AC/DS under the same Moody badge, and not an older Primrose Moody.

Keel choice decides the berth plan: fin about 1.68 m for deeper water, or bilge about 1.20 m for British drying berths. One "336" name, two marina lives in the Baltic or on UK drying moorings; bilge boats are rarer. A roomy saloon and aft cabin sell comfort on 33 feet - that does not cancel moisture mapping or chainplate work.

A neighbouring card easily turns out to be a Moody 34, 346 or 36 MkII, or a Hanse-era Moody from 2007 (Dixon may still be named, but the yard is already different). Buyers think they are comparing one model and instead mix generation, another hull, and the post-Plymouth line. This 336 is aft cockpit with a large aft cabin, not a centre cockpit like an HR 36.

Until the boat is hauled, chainplate bedding and partial-bulkhead plywood, osmosis or barrier history (bilge without topcoat, tanks laminated into the hull), rust at keel bolts, Mk1 Volvo 2003 versus later MD2030B, standing-rigging age and invoices stay unknown. Short-handed sailing without a trustworthy autopilot on this deck is a separate budget line. You buy the survey, not the badge.

Design history

The Moody 336 was designed by Bill Dixon and built by Marine Projects (Plymouth). Beyond the basic specs, the model is defined by its two draft options, a fin keel at ~1.68m and a twin (bilge) keel at ~1.20m, and its spacious aft-cockpit layout (distinct from the center-cockpit designs of the era). The evolution from Mk1 to Mk2 and the S336 brought changes to salon windows and deck hardware. Early hulls typically featured the Volvo 2003 engine, while boats built from autumn 1993 onwards usually carry the MD2030B.

While some secondary sources list production ending as late as 1998, the actual Marine Projects window is 1988–1996; late registrations should not be confused with a model relaunch. The 336 is part of the Plymouth legacy and shares no DNA with the Hanse-era Moody AC/DS models introduced in 2007. It should also be strictly distinguished from the Moody 34, 346, or 36 MkII hulls.

Annual ownership costs

A British coastal classic like the Moody 336 (~200 hulls) offers steady but niche liquidity. Maintenance costs for this 10m class are predictable, provided you account for the replacement of aging sails, deck hardware, and heating systems. The primary financial risk is the moisture map, specifically around the chainplates, where a low asking price often masks structural neglect. UK-sourced spares remain a standard reserve for boats in Northern waters. Note: The figures below are in Swedish Krona (SEK) for Stockholm/Gothenburg benchmarks; a full osmosis treatment or a complete sail wardrobe replacement falls outside these annual ranges. Budget approximately 80,000–210,000 SEK per year for high-standard upkeep.

Item	Low (SEK)	High (SEK)	Notes
Mooring	24,000	55,000	~10m class, Stockholm/Gothenburg
Insurance	7,000	18,000	Agreed value policy
Winter Storage/Lift	10,000	24,000	Crane and keel supports
Antifouling/Hull	5,000	14,000	Materials and labor
Engine/Systems	5,000	16,000	Volvo Mk1/Mk2 service packs
Rigging Reserve	6,000	18,000	Standing rigging age factor
Sails/Deck/Moisture	13,000	35,000	Sail inventory, seals, barrier
Total per year	~80,000	~210,000	Excludes major osmosis refit

Pre-purchase survey checklist

Pre-Deposit Checklist: Moody 336

Verification: Does the year on the builder's plate match the listing? (Watch for the common 1987 'ghost' start date).
Dimensions: Are the LOA and Beam 10.19m x 3.53m? (Confirm it's not the 10.21m x 3.42m catalog drift).
Heritage: Is this a Dixon-designed Marine Projects hull (1988–1996)? Ensure it's not a mislabeled 34, 346, 36 MkII, or a Hanse AC/DS.
Draft: Which keel is fitted, the ~1.68m fin or the ~1.20m twin (bilge)?
Structural Integrity: Check chainplate seals and partial bulkhead plywood for signs of water ingress.
Hull Condition: Review the moisture map for osmosis or barrier coat history; inspect keel bolts and the keel-to-hull joint.
Engine: Identify if it's the early Volvo 2003 or the later MD2030B; verify service history beyond the basic model badge.
Layout: Confirm the aft-cockpit configuration. Do not assume S336 specs or cabin counts from other listings apply to this specific hull.

Expert verdict

FairHelm rating: 7.8/10: The Moody 336 (Bill Dixon, 1988–1996, ~200 hulls, 10.19×3.53) is a practical British coastal cruiser. FairHelm judgment: buy the moisture survey, not the badge alone.

Pros: Useful coastal layout, familiar British systems for many UK-origin buyers, and ask prices that can undercut Swedish premium peers near this LOA.
Cons: Osmosis or barrier history on older GRP, deck-hardware bedding after freeze seasons, and UK parts logistics on Nordic berths.
Who it suits: Buyers who want British coastal manners on a Baltic berth and will fund a moisture map before cosmetics. Unknown: blister extent and chainplate state until hauled; reject fixture start year 1987.

Moody 336 cockpit works well for short-handed archipelago sailing. We rebedded deck hardware in spring one — worth every hour.
