Can a 45-footer take on the 50s? Sailing and full tour of the new Jeanneau Sun Odyssey 455

Stepping aboard hull number 3 of the Jeanneau Sun Odyssey 455 anchored in the bay off Cannes in southern France, Yachting World test editor Toby Hodges set out to determine whether a dedicated 45-foot production cruiser can compete against established 50-foot models. Having previously inspected hull number 2 at the boat show in Düsseldorf, Hodges met up with Michael off the coast of Cannes to run an early sea trial on the newly minted flagship of Jeanneau’s ninth-generation Sun Odyssey cruiser line.

The Lombard hull design represents the French shipyard’s first completely fresh hull mold for its ninth generation, tasked with replacing both the 440 and the 490 from the eighth generation. Facing very light breezes of four knots in the anchorage, Hodges initiated a detailed forensic walkthrough of the deck arrangement, cockpit layout, and interior accommodation before setting sail offshore to test the rig under overlapping genoa, Code Zero, and asymmetric spinnaker.

Cockpit Architecture and Walk-Around Deck Layout

The hull features a 4.5 m beam carried right through to the transom, paired with Jeanneau’s trademark sloping walk-around side decks. Boarding from the water or dock leads directly across a wide fold-down transom platform that serves as a spacious teak-alternative recreation terrace. As Hodges observed while lowering the swim platform on its tackle:

“Big bathing platform is the easiest way of extending your yacht”

Jeanneau arranged the cockpit on a single level without an aft bench or transverse wet bar interrupting the flow, allowing clear walkthrough passage from the stern straight to the companionway. Because the cockpit sole sits lower than on comparable models, the drop down into the saloon requires only four steps rather than five companionway steps. Twin helm stations feature double seats mounted on gas struts, giving access beneath to the steering gear and lazarette.

A key ergonomic feature is the placement of the primary winches well inboard of the helm pedestals rather than right on the quarters, keeping working tail lines clear of the sloping side decks. Reviewing the helm station layout, Hodges noted:

“it allows you to work those winches safely inboard holding onto something”

Twin cockpit tables with folding leaves allow comfortable center walkthrough access. When lowered on optional telescopic pedestals, both tables convert into expansive double day beds. A dedicated liferaft locker sits beneath the cockpit sole, while the after lazarette compartment provides structural access to twin rudder stocks linked by an aluminum tie bar alongside the mechanical quadrant, emergency tiller socket, and autopilot drive unit.

Interior Accommodations and Service Engineering

Below decks, the Jean-Marc Piaton interior design prioritizes natural light with oversized coachroof windows, hull ports, and multiple deck hatches. To solve the common boat-show complaint of creaking soles underfoot, Jeanneau screwed down the floorboards throughout the cabin, fitting latched inspection covers only over high-frequency maintenance access points.

Around 70% of private buyers select the three-cabin, two-head owner arrangement demonstrated on test hull 3. This layout provides an en-suite forward master stateroom, twin aft cabins, and a private utility room on the starboard side. Fitted with a hanging rail, shoe cubbies, and modular storage crates, this utility space caters to long-distance cruisers seeking dedicated stowage for foul-weather gear, provisions, and spare boat parts.

At the navigation station, the shipyard engineered an innovative forward-facing captain’s chair contoured like a bucket seat from an offshore racing yacht. Hodges singled out this arrangement as an exceptional feature:

“probably the most comfortable nav seat I’ve seen on a production boat that comes as standard”

The companionway opens onto an L-shaped galley equipped with deep double stainless steel sinks with fitted covers, an inset waste bin system, top-loading and front-opening refrigeration, and 230 V power outlets inside a deep storage alcove. Auxiliary propulsion comes from a standard 57 hp Yanmar diesel engine paired with a sail drive, though the test vessel featured the optional uprated 80 horsepower Yanmar unit. Engine service access is provided via a gas-strut companionway lift and twin lateral access panels on each side. A 380 L freshwater tank sits below the forward berth, positioned forward of the bow thruster compartment.

Rig Configuration and Deck Hardware

The Sun Odyssey 455 carries a Z Spars two-spreader fractional mast supported by wide outboard chainplates mounted to the hull topsides. The test boat featured standard Dacron sails with a conventional stack pack mainsail, controlled by a German mainsheet system led forward along the boom and back through coaming tunnels to the inboard primary winches. To preserve clear side decks, Jeanneau eliminated long genoa tracks in favor of low-friction 3D lead rings adjustable from the cockpit.

On the foredeck, a sturdy composite bowsprit accommodates an integrated anchor roller, ground tackle windlass, and attachment points for both the headsail furler and an optional flying Code Zero furler. Just aft of the chain locker, a deep sail locker accessible by an aluminum ladder swallows large downwind sails and multiple mooring fenders.

Sea Trial Performance Off Cannes

Underway trials off Cannes began in five knots of true breeze. Flying an overlapping genoa, the 455 recorded three knots of boat speed. Unrolling the bowsprit-mounted Code Zero lifted boat speed to three knots, generating apparent wind and noticeably improving helm feel. Evaluating headsail options for cruisers, Hodges remarked:

“having an overlapping Genoa makes a lot of sense in these lighter weight conditions”

Toby Hodges, Yachting World

As the sea breeze built to six knots true with 7.5 to 8 knots apparent, the Sun Odyssey touched five knots through the water despite carrying a fixed three-blade cruising propeller. Later hoisting the asymmetric spinnaker on a broad reach between 60 and 70 degrees apparent, the yacht held 4.5 knots in four knots of breeze. When wind pressure finally increased to eight knots true, boat speed climbed to seven knots. Heading back toward Cannes under sail, true wind peaked at 10 knots, propelling the yacht to 7.5 knots of speed with a steady heel angle.

Base pricing for the Jeanneau Sun Odyssey 455 starts at 353,000, presenting a high-volume cruising proposition positioned to challenge 50-foot alternatives across the European production yacht market.
