Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her light displacement on a moderate beam gives 24 — a moderate, middle-of-the-road motion.

Comfort ratio 24
CoastalBluewater

2.03 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.03
LightHeavy

125 — light for her waterline, so she is easily driven and quick to accelerate.

Displacement / length 125
EasygoingPowered-up

19.1 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 19.1
TenderStiff

24% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 24%

Light and lively — happiest day-sailing and coastal-hopping in settled weather.

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Jeanneau Sun Odyssey 455 is a fractional sloop designed by Marc Lombard and Jean-Marc Piaton, built by Jeanneau since 2026, featuring a fin with bulb and dual rudders. With an LOA of 14.3 m and a displacement of 11230 kg, it offers a standard draft of 2.4 m, with a shoal keel option reducing draft to 1.75 m. The hull's extended knuckle span creates a full-size double berth in the forward cabin, and a utility room aft of the galley can accommodate a washing machine or an extra refrigerator.1:43 The galley is U-shaped and runs longitudinally, featuring a deep top-loading refrigerator.2:30 Inboard chainplates clear the side decks, and recessed winches allow for grinding without obstructing the cockpit.4:09 All running rigging leads to the coachroof, and large chart plotters are mounted on raised pods at the helm. Jeanneau has standardized a tall rig across its range to manage build complexity and pricing.4:52 Aboard SEILmagasinet, the 455 is positioned for the Norwegian market at approximately 5.5–6 million NOK fully equipped.0:01
