Design and Construction
The 45.2 measures 46 feet 5 inches overall, with a 38-foot-5-inch waterline and a beam of 14 feet 8 inches carried well aft. Displacement is a relatively light 21,605 pounds, including 8,102 pounds of iron ballast in a bulb fin. Briand’s D/L ratio of 170 confirms that she’s light for her length.
That lightness contributes to quick, surf-friendly manners downwind, while the high-volume hull provides immense interior space and initial stability. Her initial stability also keeps her from heeling much in light air.
Below the waterline, the hull is solid hand-laid fiberglass, with Kevlar reinforcement in the bow sections. This “collision mat” adds impact resistance for offshore encounters with debris or containers and offers some peace of mind in those waters Kevlar bow impact resistance. The deck uses a balsa core for stiffness and reduced weight, and the overall low-maintenance GRP construction will be familiar to boatyards worldwide.
The standard bulbed fin keel draws 6 feet 7 inches; a 5-foot-3-inch shoal-draft version was also available. A deep, balanced spade rudder handles steering. The capsize screening ratio is 2.11, slightly above the traditional 2.0 offshore benchmark. That places the 45.2 more in the coastal-and-offshore cruiser category than among dedicated Southern Ocean storm boats. In extreme breaking-wave rolls, her width makes her slightly more prone to remaining inverted than a narrow, heavy-keeled specialist.
Rig, Performance, and Handling
The masthead sloop carries roughly 1,001 square feet of sail and has a sail-area-to-displacement ratio of 20.7. That generous sail area delivers strong light-air performance, keeping the boat moving in Mediterranean or Caribbean breezes when heavier boats may resort to the engine.
The trade-off is that she becomes overpowered quickly. Once the wind rises past 15 to 18 knots, she needs early reefing. A test sail found her footing happily about 50 degrees off the wind at 6 knots in 19 knots of apparent breeze.
The standard rig includes a furling mast and rigid vang, and the all-furling sailplan is controlled from the large aft cockpit. Single-pod chainplates set well inboard allow the genoa to be strapped in tightly for close angles. The mainsheet traveler is forward of the companionway, with midboom sheeting, and all sail controls lead aft through deck organizers. A split backstay improves access over the stern.
The main handling drawback is winch placement. The primary winches sit at the aft end of the coachroof, beyond the helmsman’s reach. When sailing single-handed, tacking therefore depends on the autopilot holding course while the sailor moves forward to work the sheets.
Cockpit and Deck Layout
Twin steering wheels define the cockpit and leave a clear central walkway between the companionway and reverse transom. This arrangement makes access to the water or dinghy easy and gives the helmsman a choice of steering positions, reducing fatigue on long passages. The beam carried well aft provides enough room to make the twin-wheel layout practical.
The teak-covered cockpit seats are angled for comfortable sitting when the boat is heeled and are long enough for sleeping under the stars. A huge cockpit table with a built-in ice chest fills the center of the space. Port and starboard gull-wing lockers flank it, and a large lazarette sits between the wheels.
Twelve opening hatches help keep the interior ventilated without cluttering the deck. Forward, the double anchor roller and pulpit step sit above a below-deck headsail-furling drum in the anchor locker. A watertight deck locker and sail bin just aft of the chain locker accompany two stout midships cleats.
At the stern, the opening transom has a stern step and deep ladder. A swim ladder stows in its own locker, completing a layout well suited to swimming and Mediterranean-style mooring.
Accommodations
Jeanneau offered two layouts. The owner’s version has one forward cabin and two double aft cabins. The charter edition has two double cabins forward and two aft.
In the owner’s layout, the forward stateroom includes a centerline queen berth, mirrored vanity, and light teak cabinetry. Its extraordinary head has a curved door enclosing a separate shower. Both heads are molded entirely in fiberglass.
In the saloon, a starboard settee and freestanding centerline seat surround a teak table that the builder claims can seat 10. Opposite, the well-regarded linear galley runs along the port side. It includes double sinks, a four-burner stove and oven, separate fridge and freezer, and an ingenious sliding food locker. The long layout allows several people to use the space without getting in the cook’s way.
The navigation station is angled 30 degrees off center beneath the starboard side deck, opposite the aft head. Opening portlights in every cabin, together with the deck hatches, provide excellent ventilation throughout.
Machinery and Known Issues
The upper rudder bearing is the main area that demands maintenance attention. Its original galvanized-steel carrier can rust if water collects in the housing, and many owners replace it with a custom stainless-steel or bronze version. Some owners also report that chain can pile up in the anchor locker unless retrieval is monitored.
The boat is listed with a 62-horsepower Yanmar diesel, while most examples carry a 4JH-series engine of roughly 56 to 75 hp. Access is good through the companionway steps and aft-cabin hatches. The engine installation includes a dripless, maintenance-free stuffing box, and Yanmar’s global parts network helps make the boat a durable, ergonomic candidate for bluewater passages.
The Verdict
The Sun Odyssey 45.2 balances two roles: Mediterranean charter platform and capable offshore passage-maker. She’s fast and rewarding in light to moderate air, but needs a proactive hand on the reefing lines as the breeze builds. She best suits a buyer who keeps her lightly loaded and pays close attention to the upper rudder bearing.
Pros
- Light, agile hull with strong light-air performance and surf-friendly downwind speed
- Kevlar bow reinforcement for offshore impact resistance
- Twin-wheel cockpit with a clear transom walkway and easy water access
- Spacious, well-ventilated three- or four-cabin interiors with a standout linear galley
- Reliable Yanmar 4JH-series diesel with worldwide parts support
Cons
- Upper rudder-bearing carrier can rust if water collects; many owners replace it
- Light displacement and lively motion punish overloading and require early reefing
- Winches forward of the helms complicate short-handed tacking
- Wide beam and 2.11 capsize screening ratio make her less suitable for dedicated heavy-weather Southern Ocean work
