Dufour 310 Grand Large Sailboats for Sale

Felci Yachts' hullform wrings remarkable beam from a short waterline, producing a wide stern that supports a genuinely social cockpit and twin wheels that are unusual — some would say indulgent — at this length. Buyers should understand going in that the twin-wheel arrangement adds mechanical complexity and, as Yachting Monthly's on-water test noted, there is rotational inertia feedback between the two wheels that tiller-accustomed sailors find disconcerting. Upgrading to carbon-fibre wheels addresses the feel but adds meaningful cost. The self-tacking jib is a practical asset for shorthanded passages; the trade-off is reduced sail area on a broad reach, which is why a 110-percent genoa option appears on the specification sheet and on many used examples.

The most important pre-purchase finding from authoritative sources is the engine bay. The standard engine installation makes fuel hand-pump use impossible without removing ventilation ducting, and fuel-filter, oil-filter, dipstick, and oil-cap access are all described as genuinely difficult. This is not a matter of opinion; it is a design constraint baked into the production run. Any used example should be evaluated for whether a previous owner addressed these access issues — some have fabricated custom hatches or rerouted ducting — and buyers who plan to do their own engine maintenance should be particularly realistic about the effort involved.

Layouts on the Used Market

The 310 Grand Large was sold in three configurations — Day Sail, Liberty, and Adventure — distinguished principally by outfitting level rather than structural cabin arrangement. Below decks, the layout follows a consistent pattern across the production run: a large, light-flooded saloon with opposing settees and a folding table, a port-side galley aft of the saloon, a starboard head with shower, a spacious V-berth forward, and a single aft cabin to port. The forepeak bulkhead is the boat's clever signature feature: it folds away in sections to merge the forward cabin into the saloon, creating a near open-plan interior for daysailing couples and restoring privacy for overnight passages with a crew aboard.

The aft cabin suits a child or a solo sleeper comfortably; it is a stretch for two adults. That constraint is characteristic across the entire used inventory, so buyers expecting symmetrical twin-cabin accommodation in thirty-one feet will be disappointed regardless of which example they view. The forward V-berth, by contrast, is genuinely double-sized once the infill cushions are placed, with overhead-window illumination making it one of the more pleasant sleeping quarters available at this length.

Equipment and Common Upgrades

Used examples across France, the United Kingdom, Croatia, Portugal, and the United States tend to be outfitted generously relative to their size, reflecting the buyer profile Dufour targeted. A self-tacking jib is essentially standard across the fleet. Code zeros and asymmetric spinnakers are commonly fitted, giving these boats genuine downwind capability that transforms passage-making in light-to-moderate conditions. Autopilot and chartplotter are found on nearly every used example, and hot-water systems are a consistent feature rather than an exception.

Biminis appear widely, particularly on boats that have cruised Mediterranean or Atlantic-coast waters, where cockpit shade matters more than racing performance. Many owners have added swim platforms and cockpit showers, and teak deck sections appear on a meaningful share of listings — desirable cosmetically but worth inspecting carefully for delamination or water ingress at fastenings, as with any teak overlay on a boat this size.

A gennaker and furling mainsail are occasional owner additions rather than fleet-wide standards; when present they signal an owner who pushed the boat beyond coastal day-sailing. A bow thruster appears on a minority of examples, typically on boats that spent time in tighter marina environments. Life rafts are present on some listings and absent on others; buyers purchasing for bluewater use should budget for a serviceable unit regardless.

What to Inspect

The engine access issue is the top priority at any survey: the fuel hand pump cannot be operated without first removing engine-bay ventilation ducting in the standard installation, and oil and fuel filter access is described as genuinely restricted. Confirm whether a surveyor can reach the dipstick and oil cap without obstruction, and ask the owner or broker to demonstrate any remedial work done. An engine that has been difficult to service is an engine at higher risk of deferred maintenance.

The twin-wheel steering system involves two stainless-steel wheels linked by cable or hydraulic run; inspect the steering box, linkage, and cables for wear, especially on boats that have logged significant offshore miles. The steering feel is otherwise described as finger-light, with twin rudders providing good grip and direct feedback, so any heaviness or slop should prompt close attention.

The large overhead skylights and freeboard ports that define the saloon's light character are options on some builds rather than standard; they are described in authoritative reviews as genuinely transformative for the interior, so if they are absent on the boat you are considering, understand you are looking at the base specification. Seal condition on those hatches and ports warrants inspection — water ingress around polycarbonate deck lights is a recurring issue on boats of this era regardless of builder.

Check the forward folding bulkhead mechanism — the multi-panel door that opens the forepeak into the saloon. The system is mechanically simple, but track and hinge wear on a heavily used boat can make the panels stiff or misaligned. Stowage volume is constrained by the hull's length; lockers and bilge compartments should be dry and free of standing water or mildew suggesting drainage problems.

The hull carries a Category B offshore rating for use up to Beaufort 8 and four-metre seas, but the draught is considerable for a 31-foot boat — approximately 1.90 metres in the standard keel configuration, which limits access to shallow anchorages in the Mediterranean and UK coastal waters. A ballasted centreboard option was available; boats so fitted should have the mechanism inspected for smooth operation and absence of play.

Availability and Buyer's Takeaway

The 310 Grand Large circulates most actively in France and the United Kingdom, where Dufour maintains its strongest dealer and brokerage presence, and across the Mediterranean littoral — Croatia and Portugal appear consistently in the used inventory. North American listings exist, with the United States showing a portion of the market, though availability there is thinner than in Europe.

This is a boat that rewards thorough pre-purchase inspection precisely because its greatest virtues — the cavernous interior, the confident offshore rating, the easy shorthanded sail plan — can mask deferred engine maintenance that the difficult access makes tempting to postpone. A qualified marine surveyor who can spend time in the engine bay, not merely report on it, is non-negotiable.

Pre-purchase checklist:

• Engine access audit: fuel hand-pump operability, filter and oil-cap reach, dipstick access
• Twin-wheel steering system: cable condition, linkage play, wheel inertia feel
• Hatch and portlight seals: all deck openings, especially overhead saloon skylights
• Forward folding bulkhead: track, hinge, and alignment across all panels
• Teak deck overlays if present: fastening integrity, delamination, water beneath
• Keel-to-hull joint: sealant condition, staining, any weeping around the ballast stub
• Centreboard mechanism if fitted: smooth operation, absence of play or binding
• Offshore safety kit: life raft serviceability, flares, harness points
• Self-tacking jib and downwind sail inventory: sheet wear, furling drum condition
• Hull Category B fitness: standing rigging, chainplate fastenings, through-hull condition
