The Jeanneau Sun Way 28 CB represents a pivotal era for the French shipyard, bridging the gap between performance-oriented designs and the burgeoning demand for family-friendly coastal cruisers. Launched in the early 1990s and designed by the renowned naval architect Tony Castro, the Sun Way 28 was conceived as an accessible entry point into the yachting lifestyle. The "CB" designation denotes the swing-keel (centerboard) configuration, a design choice that significantly expanded the cruising grounds for owners by allowing access to shallow estuaries and drying harbors—territories often off-limits to its fixed-keel sibling. Despite its modest length of just under 28 feet, the hull carries a generous beam of nearly 10 feet, typical of Tony Castro’s ability to maximize internal volume without sacrificing the sleek, European aesthetic that defined Jeanneau during this period.

Sailing Performance & Handling
The Sun Way 28 CB is recognized for its balanced and forgiving nature, making it an ideal platform for shorthanded crews or those new to keelboat sailing. Because it utilizes a swing keel, the ballast is concentrated in a stub keel and the centerboard itself, which results in a slightly different center of gravity compared to the deep-fin version. In light to moderate air, the boat is remarkably lively; the hull's relatively light displacement allows it to accelerate quickly out of tacks.
Under sail, the boat exhibits a fair degree of "feel" through the tiller, though the centerboard version does trade some ultimate upwind pointing ability for its shallow-draft utility. Owners frequently note that the boat tracks well when the board is fully deployed, but like many lifting-keel designs, it can experience increased leeway in heavy gusts if not properly trimmed. The sail plan is typically a masthead sloop with a large genoa, providing the power necessary to push through choppy coastal waters. According to historical design notes from the era, the boat was engineered to prioritize "easy sailing," which manifests in a stable platform that remains predictable even as the breeze freshens.
Interior Comfort & Variations
For a vessel of 28 feet, the Sun Way 28 CB offers an interior volume that was considered revolutionary at its launch. Jeanneau utilized an open-plan layout in the main saloon to enhance the sense of space, a design hallmark that made the boat feel significantly larger than its contemporaries. The use of light-colored woods, often ash or light oak, further brightened the cabin, moving away from the dark, cavernous interiors of the previous decade.
The layout features a dedicated V-berth forward, which is often left open to the saloon to maintain airflow, and a surprisingly spacious aft cabin tucked under the cockpit sole. This aft cabin was a significant selling point, providing a degree of privacy rarely found in sub-30-foot boats of the early 90s. The L-shaped galley is functional for coastal hops, typically equipped with a two-burner stove and a modest icebox.
The primary variation of this hull is the standard Sun Way 28, which features a fixed fin keel. While the fixed-keel version offers superior stiffness and upwind performance, the CB variant is more sought after in regions with high tidal ranges or shallow cruising grounds, such as the Chesapeake Bay or the French Atlantic coast. Both models share the same deck mold, featuring a clean, uncluttered cockpit with lines led aft for ease of handling.
Known Issues & Buyer’s Checklist
Prospective buyers should focus their inspections on the specific mechanical and structural elements of the lifting keel system.
- Centerboard Pivot and Pennant: The most critical area for the CB model is the pivot pin and the lifting pennant. Over time, the pin can wear, leading to "keel clank" when at anchor or under sail. The lifting cable should be inspected for fraying, as a failure can result in the board being stuck in the down position.
- Deck Hardware Bedding: Like many production boats from the 1990s, the Sun Way 28 can suffer from moisture ingress around stanchion bases and cleats. Check for soft spots in the deck sandwich core, particularly around the mast step.
- Rudder Bearings: The spade rudder is effective but can develop play in the bearings. If the tiller feels "notchy" or vibrates excessively while under power, the bushings likely require replacement.
- Engine Maintenance: These boats were commonly fitted with small Yanmar or Volvo Penta diesel engines. While reliable, the tight engine compartment makes checking the heat exchanger and water pump difficult, often leading to deferred maintenance in these areas.
Community & Resources
Owners of the Sun Way 28 CB benefit from a robust international support network. The Jeanneau Owners Network serves as the primary repository for technical manuals, rigging diagrams, and historical brochures. This community is particularly active in Europe and North America, offering specific advice on modifying the centerboard mechanism and sourcing replacement parts for the Castro-designed hull.
The Verdict
The Jeanneau Sun Way 28 CB remains a highly capable and versatile small cruiser that punches well above its weight class in terms of interior accommodation and coastal utility. While it may not satisfy the "purest" racer due to the compromises of the swing-keel design, its ability to explore shallow waters and provide comfortable overnighting for a small family makes it an enduring favorite on the used market.
Pros:
- Exceptional interior volume and a genuine aft cabin for its size.
- Versatile shallow draft (CB version) allows for "gunkholing" and easy trailering/storage.
- Predictable and forgiving handling characteristics.
Cons:
- Lifting keel mechanism requires more maintenance than a fixed fin.
- Light displacement means it can be "tender" in heavy weather, requiring early reefing.
- Upwind performance is slightly hampered compared to the deep-keel variant.
