Hull Design and Offshore Credentials
Lombard drew a fin hull with bulb and dual rudders — a configuration that became standard practice on quality European production boats during the 2010s. Twin rudders maintain steering authority when the boat heels and load up predictably rather than suddenly, which matters when conditions deteriorate offshore. The capsize screening formula comes in at 1.99, just within the threshold considered suitable for ocean passages, confirming that the wide beam has not come at the cost of seakindliness. The displacement-to-length ratio of 172 places the 389 firmly in the light-displacement bracket, and the CE Category A certification for eight people confirms the design's seakeeping credentials at the regulatory level. Three keel options — standard, shoal, and swing — give buyers meaningful flexibility depending on their cruising grounds.
Rig, Sail Plan, and Handling
The fractional sloop carries a modest but well-proportioned sail plan: the I measurement of 46.6 feet and P of 44.6 feet produce a reported sail area of 754 square feet, and the sail area-to-displacement ratio in the range of reasonably good performance means the boat moves well in a breeze without demanding the crew be athletes. A full-size headsail on a furling system is standard in most configurations; charter experience confirms she sailed great both upwind and downwind, achieving hull speed readily in the afternoon Mediterranean thermal winds that run to 15 knots. The Code 0 option, reflected in published polar curves for every keel variant, extends the light-air range meaningfully when fitted with a bowsprit. Visibility from the twin-helm station is a consistent positive, and the cockpit offered good visibility from the helm even with a full charter complement aboard.
Cockpit and Deck Layout
The cockpit represents some of the 389's most thoughtful engineering. An innovative cockpit table with integrated storage, a bench lazarette, and two deep aft lockers — one purpose-built for gas cylinder stowage — demonstrate that Jeanneau's production team thought through daily liveaboard logistics. Companionway steps were designed more like stairs than a ladder, a refinement that makes moving between deck and saloon with loaded arms or at night significantly safer. Grab rails and handholds are well placed both above and below deck for safe movement in a seaway. The 389 also introduced a wider swim platform relative to the SO 379, according to the sailboatdata notes — though user experience suggests the standard platform can feel abbreviated for boats with young crew or when conditions require repeated water entries.
Accommodations
Below decks, Jeanneau offers two- or three-cabin layouts. The three-cabin version divides the interior into a forward V-berth owner's stateroom, a midship double to port, and a single aft to starboard, with two heads. Water capacity of 201 liters and a 29-horsepower Yanmar diesel back up the accommodations package for extended passages. The main head is generous by production-boat standards — the head was larger than comparable boats of the same vintage and offered comfortable standing room for showering, including room for two. Electrical provision is thorough: 220V outlets in every cabin and USB ports throughout reflects a builder responding to the connectivity expectations of modern charterers and owners alike. The galley, however, has limitations: cabinet doors are not soft-closing, and storage volume is adequate for coastal hops but may feel tight on longer passages where provisioning depth matters.
Known Shortcomings
The 389 accumulates a reasonably short list of recurring complaints, but they are worth understanding before purchase. Reefing and mainsail handling require climbing two to three steps up the mast rather than working the sail from the deck — a meaningful inconvenience in rough conditions and a genuine safety concern on a short-handed boat in any kind of seaway. The forward cabin receives natural light only through a single overhead hatch; the absence of hull windows in the V-berth leaves it noticeably darker than competing designs that fit portlights at the waterline. The galley's overhead cabinet opens downward directly over the cooktop, creating a collision hazard for anything on the burner when the locker is accessed underway. There is also no saltwater foot pump in the galley, which accelerates fresh water consumption during extended passages.
Refits and Upgrades
The structural platform is sound fiberglass construction, and the mechanical package — Yanmar diesel at 29 horsepower with a 129-liter fuel tank — is a proven combination that supports reasonable range under power. Owners commonly address the sail-handling ergonomics by adding a rigid vang or stack pack to minimize the need to go to the mast for flaking. The swing-keel variant opens up shallow-water cruising possibilities that the standard fin cannot match, though the added mechanical complexity deserves scrutiny on any used example. Upgrading to a larger swim platform or adding a telescoping boarding ladder substantially improves ease of boarding from the water — an upgrade many owners pursue early in their tenure.
The Verdict
The Jeanneau Sun Odyssey 389 is a polished, well-sorted coastal and offshore cruiser that earns its place as one of the more compelling production boats in the 38-39 foot class. Marc Lombard's hull delivers genuine seakeeping ability within a broad, comfortable package, and the interior volume and electrical provision are excellent for the size. The shortcomings — mainsail handling ergonomics, a dim forward cabin, and a functional but imperfect galley — are real but not disqualifying, and most can be addressed at modest cost.
Pros
- Dual rudders and bulb keel deliver confident, predictable handling
- Wide beam creates genuine liveaboard volume for the waterline length
- Well-engineered cockpit with practical stowage and stair-style companionway
- Generous head with comfortable shower for two
- Full-size headsail rewards close-hauled and downwind sailing equally
- Three keel variants suit a wide range of cruising grounds
- CE Category A certification for offshore passages
Cons
- Mainsail cannot be dropped from deck; mast steps required in all conditions
- Forward cabin relies on a single hatch for natural light
- Galley storage volume limits provisioning depth for extended passages
- Overhead galley locker hazardous to open while cooking
- Standard swim platform is abbreviated for a boat this size
- No saltwater foot pump reduces self-sufficiency on long passages
