Dufour 310 Grand Large

Parker Adams are delighted to offer Calypso, a much-loved and meticulously cared-for Dufour 310 Grand Large, first commissioned in March 2015. With a host of recent upgrades, she’s in excellent condition and ready to sail away.

At just over 30 feet (9.67m), the Dufour 310 may be the smallest model in Dufour’s acclaimed Grand Large range, but she packs in a huge amount of character, performance, and innovation. Designed with ease of handling in mind, Calypso is ideal for short-handed or even single-handed sailing, making her a perfect choice for couples, small families, or those new to yacht ownership.Built with the same principles, style, and quality as her larger Dufour sisters, the 310 delivers superb sailing performance, smart design, and impressive onboard comfort. She’s particularly well-suited for coastal cruising, and her compact size means she can slip easily into the most beautiful and sheltered anchorages. Below decks, the Dufour 310 makes excellent use of space, offering both practical functionality and stylish comfort for relaxed living aboard.

She has benefited from a range of recent upgrades and essential maintenance.In 2023, all seacocks, skin fittings, and associated plumbing were professionally replaced. In 2025, three new batteries were installed—one starter and two domestic—with an override system that allows all battery power to be diverted to the starter in the event of an emergency.Most recently, in October 2025, she was antifouled, and the hull treated with a high-performance ceramic coating and Prop One application on the propellor. 

Owners Comments

We sail her regularly in all the usual Solent haunts and have made trips to France and the Channel Islands in her, she is such a pleasure to sail & we always arrive first when on joint trips with friends!Rigged with the German mainsheet system which leaves a completely clear cockpit but this can be switched to traditional if preferred - we have the tackle on board but never used.
