Design and Construction
Dufour built the Atoll 43 in fibreglass, using the solid-hull construction typical of the yard’s sub-50-foot boats of the period. The deck is also solid fibreglass. Below the waterline, she carries lead ballast, a fin keel, and a spade rudder.
The Atoll’s defining feature isn’t her moulding but her architecture. She was specifically designed for charter use, and that brief produced a layout with all the main living and entertaining areas on deck around the cockpit. This exterior living space occupies close to half of the boat’s 13.1-metre length. A hard top, hood, and windscreen provide shelter, and the area can be heated when conditions turn.
Her dimensions and displacement are substantial: around 9.5 tonnes, with a 4.64-metre beam and a 1.6-metre draft.
Cockpit and Accommodation
The walk-through transom incorporates a well and swim ladder for easy cockpit access. From there, three steps lead beneath the deck to the sleeping quarters, but the heart of the boat remains above.
The daytime living area includes a large saloon with padded wraparound seating. A vast galley to port provides more than 300 litres of cold storage, while the navigation station is to starboard. There’s also a cushioned sunbathing well set into the foredeck.
Below, the Atoll 43 can accommodate a charter party of up to eight, with four double berths across four cabins and a salon, plus two heads. The two forward cabins can be combined into a single master cabin if required. Opening hatches and ports ventilate all the cabins, and purpose-built lockers provide ample stowage throughout.
Rig, Performance, and Handling
The Atoll 43 carries a fractional sloop rig with 88 square metres of sail. The builder fitted a large fractional rig with a fully battened mainsail, single-line reefing, and a furling headsail with just 110 percent overlap.
All winches, sheets, and control lines are within easy reach of the helmsman, setting the boat up for single-handed sailing despite her size. Sail balance remains an important consideration. Although every yacht needs careful sail balance for best performance, the Atoll’s trim must be watched closely to keep her sailing at her best.
Writing in Seamagazine, testers described her as stiff and stable, with a balance number of 1.6. They noted that she performs well offshore but may need reefing often.
Under power, a 62 hp motor driving a three-bladed propeller takes her to about 8 knots.
Equipment and Tankage
The Atoll 43 carries twin 550-litre water tanks, giving a total capacity of 1100 litres, along with 500 litres of fuel. Those figures suit extended charter turns. Her auxiliary engine is a 62 hp diesel rated at 2400 rpm.
The navigation inventory aboard one surveyed example included GPS, a chartplotter integrated with the GPS, autopilot, radar, a depth sounder, and wind instruments.
Verdict
The Dufour Atoll 43 is a limited-production charter boat that treats the deck as the saloon and the cabin as the dormitory. For buyers who want open-air living and genuine offshore stability, she offers a stiff, well-tanked platform with sail controls arranged for single-handed use.
Her unconventional layout and short production run make her a niche choice rather than a mainstream cruiser.
Pros
- Exceptional above-deck living space occupying nearly half the hull length
- Stiff, stable hull with offshore capability, according to a period review
- Sail-handling controls arranged within reach of the helm for single-handed sailing
- Generous capacity of 1100 litres of water and 500 litres of fuel for extended use
Cons
- Only 40 were built, so spares and comparable boats are scarce
- The inside-out layout leaves only a minimal conventional saloon below deck
- Sail balance requires active management for best performance
