Windbreaker is a 2015 Jeanneau Sun Odyssey 439 that has been rebuilt system by system since 2022 into a boat that is ready to leave the dock, not one that needs a season of work first. The current owner is a hands-on, detail-driven maintainer who documents everything, down to a physical maintenance log kept aboard and a digital archive of every service receipt. In his own words, "the goal was to make this a boat where the next owner looks at it and thinks: he already did this, so I don’t have to." That makes Windbreaker the right choice for a buyer headed south this winter, to the Bahamas or the Caribbean, who wants a capable, well-sorted 439 with the upgrades already finished rather than a project to inherit.
The Jeanneau Sun Odyssey 439 was designed by Philippe Briand, who drew 45 production models for Jeanneau over 38 years, and the boat carries the résumé well. The hull has a near-plumb bow, hard chines aft, and a fiberglass structural grid tying keel and rig loads into a hull built with Jeanneau’s Prisma resin-infusion process, hand-laid fiberglass below and a balsa-cored deck above, for a hull that is strong without being heavy for its size. Sail Magazine tested the 439 off Annapolis in a cold front with gusts over 20 knots and called it, in the reviewer’s words, “quite simply a joy to sail: both steady and nimble,” noting that it sliced through a short, stiff chop instead of pounding and came through tacks effortlessly. Cruising World’s sea trial had the boat making 7 knots close-hauled and 8.5 knots reaching in just 16 knots of breeze, and found it light on the helm and easy to sail short-handed, with every control led back to the twin wheels.
The deck layout backs that up. Both primary winches serve the jib and mainsheet from either helm station, so two people can reef, tack, and trim without leaving the wheel, and the recessed genoa tracks and covered line bins keep the cockpit clear underway. Windbreaker carries the shoal-draft keel, 5' 2" instead of the standard 7' 2", which opens up the shallow anchorages and thin-water cuts that keep a lot of deeper cruising boats offshore, exactly the places a Bahamas or Eastern Caribbean itinerary runs through. This is a boat built for putting miles under the keel, not just for looking good at the dock.
A 439 set up like Windbreaker is built to be lived on, not just sailed. The 2-cabin, 2-head layout means two couples can each have a real cabin and a private head instead of trading off a single one, and the wide beam carries through into the galley and salon so the boat does not start to feel small three weeks into a trip. Ventilation is a strong point of the design, with opening ports and hatches throughout that keep the cabin livable at anchor in warm climates before the air conditioning ever comes on, and on Windbreaker, three separate reverse-cycle zones mean the forward cabin, aft cabin, and salon can each be run independently.
The systems are what make extended time aboard realistic rather than aspirational. With 600Ah of lithium and 1,300 watts of solar, the boat can run refrigeration, air conditioning, and everyday loads for days at anchor without the generator, and the Onan 5kW is there as backup rather than a daily chore. The dedicated washdown pump keeps the anchor locker clean through repeated sets in soft bottoms, the spares inventory covers the parts most likely to fail on a long trip, and the freshwater-only head setup leaves a raw-water seacock free to feed a watermaker if a future owner wants one.
The electrical system is the strongest argument for this boat. In March 2023, Chesapeake Dockside rebuilt the charging and power system from the ground up and expanded it further in 2025, giving the boat a 600Ah lithium bank, full remote monitoring, and enough new 110V outlets to fix a common complaint about French-built boats running short on them.
A custom-fabricated stainless stern arch, built by Eastport Spar & Rigging through the winter of 2024 into January 2025, carries the solar array and integrates the dinghy davits. With 1,300 watts behind the lithium bank, the Onan generator has become a backup rather than a daily necessity.
The original B&G package has been fully replaced with Raymarine, installed and wired by Chesapeake Dockside across 2023 and 2024, plus Starlink for connectivity and remote monitoring from anywhere.
The Yanmar 4JH5E shows 746 hours and has been kept current on every scheduled service, including a proactive fix this spring for a known issue on this engine and saildrive pairing.
The mainsail is in-mast furling, the forestay has been replaced, and the deck hardware was re-bedded fleet-wide last fall. The sails themselves are a step up from what most 439s carry.
The ground tackle was upgraded in 2024 for a lighter, cleaner-setting anchor, and the chain is color-marked for quick reference from the helm.
The bottom, canvas, and brightwork are all current, and the boat came out of a full professional detail the week before this listing was written (early July).
Three-zone air conditioning covers the whole boat, and both heads have been fully rebuilt.
