Jeanneau Sun Odyssey 31 Buyer's Guide
Shopping the used market for a Jeanneau Sun Odyssey 31 means looking at a French Daniel Andrieu cruiser built from 1991 to 1997, now out of production but still circulating in European waters. She is a 30-foot masthead sloop with a tiller-steered spade rudder and a reverse transom swimming platform, offered in two factory interior layouts and frequently in ex-charter condition. Knowing which layouts and upgrades are common helps a buyer separate a tired charter hull from a cared-for owner boat.
Layouts on the Used Market
On the used market, owner three-cabin layouts are the more common, but both factory plans remain available, and ex-charter examples are common. The first layout sleeps four with a U-shaped settee and amidships straight galley, while the second optional layout sleeps six with two straight settees and an L-shaped galley at the companionway. Either way the boat carries a bow "V"-berth and a port-side aft double, so the real choice is berth count versus main-cabin social space. Ex-charter history is worth probing because those hulls often saw heavier cyclic use than private boats.
Equipment and Common Upgrades
Buyers will find autopilot, chartplotter, life raft, heating, and inverter commonly fitted, forming the baseline safety and comfort suite on most used boats. Often-seen additions include solar, furling main, hot water, bimini, and cockpit shower — practical cruising upgrades rather than luxuries. A frequent owner upgrade cluster brings electric winches and a spinnaker for easier short-handed sail handling, while less common but consequential options include dinghy davits and AIS for those planning longer passages. Teak decks and a dodger appear as occasional refinements rather than standard spec.
What to Inspect
The Sun Odyssey 31 was built predominantly of fiberglass with wood trim, and the fixed fin keel or optional shoal-draft keel attaches to a hull with a reverse transom swimming platform and internally mounted spade rudder. Inspect the rudder trunk and the fin-to-hull joint carefully, since the spade rudder is internally mounted and the keel is a fixed fin. The Yanmar 2GM20 diesel is fitted for docking and maneuvering, so confirm cold-start behavior and shaft alignment. Wood trim throughout should be checked for softening or discoloration that signals past leaks around ports and hatches.
Availability and Buyer's Takeaway
These boats typically appear in France, the United Kingdom, Germany, Greece, and the Netherlands, with ex-charter units most prevalent among them. For a buyer, the short checklist is: confirm which of the two factory layouts is fitted and whether it is an ex-charter hull; verify the Yanmar 2GM20 and spade rudder condition; look for commonly fitted heating and inverter as signs of cruise-readiness; and treat electric winches or davits as bonuses rather than expectations. A well-kept example rewards the buyer with a simple, tiller-driven cruiser of proven Andrieu lineage.
