Design Brief & Intent
The core mission of the Jeanneau Sun Way 28 CB was to maximize both cruising comfort and geographical versatility without sacrificing the sailing dynamics that owners expected from a Tony Castro design. To understand the Sun Way 28, one must look at its heritage: the hull is closely related to the earlier Arcadia 30, which itself was adapted from Castro's successful Half Ton racing prototypes 2 3. However, unlike the strict racing machines of the era, the Sun Way 28 was built for families and shorthanded crews who demanded a boat that was easy to handle, cheap to slip, and spacious enough for extended weekend cruising.
Within Jeanneau’s own lineup, the Sun Way 28 was positioned as the flagship of the entry-level "Sun Way" series—sitting above the trailerable Sun Way 21 and Sun Way 25—before the yard transitioned this size range into the early Sun Odyssey line, specifically the Sun Odyssey 28.1. Compared to competing French models of the late 1980s and early 1990s, such as the Beneteau First 285 or the Feeling 29, the Sun Way 28 was notable for its aggressive use of interior volume.
Stepping down the companionway reveals a cabin that feels remarkably bright and open, a direct result of the panoramic, near-continuous coachroof window wrap that flooded the saloon with natural light 6. The interior layout was highly advanced for its time, featuring a private double aft cabin with decent standing headroom at the entrance, a fully functional L-shaped galley to port, a proper navigation station to starboard, and a separate private marine heads compartment 1. The forward V-berth, while somewhat short for taller adults, opened directly into the main saloon to amplify the sense of space. Solid teak joinery and satin varnishes were used extensively throughout, providing a warm, traditional feel that contrasts sharply with the fiberglass inner liners of modern production boats.
Variations & Configurations
While the hull mold remained consistent throughout the production run, Jeanneau offered the Sun Way 28 in several distinct configurations to cater to different regional waters. The standard fin keel version carried a single deep spade rudder and offered a traditional, draft-dependent sailing profile. In contrast, the Sun Way 28 CB was engineered specifically for tidal regions and shallow estuaries, such as those found along the Atlantic coast of France and the East Coast of the United Kingdom.
The CB version features a shallow-draft cast iron stub keel that houses a pivoting fiberglass centerboard. This arrangement allows the boat to operate with a mere 2.13 feet of draft with the board fully raised, extending to 5.08 feet when the board is lowered for upwind performance. Because of the mechanical housing and the reinforced structure of the stub keel, the centerboard version is heavier than its fin-keeled sibling, displacing 5,732 pounds compared to the fin's 5,291 pounds.
Crucially, to preserve steering control when the centerboard is raised or when the boat is heeled in shallow water, Jeanneau equipped the CB version with twin rudders. These twin rudders are splayed outward, ensuring that the leeward rudder remains fully vertical and deeply immersed even when the boat is pressed hard on a reach. Additionally, while the earlier Sun Dream 28 utilized a masthead sloop rig, the Sun Way 28 made the transition to a modern fractional sloop rig. This fractional configuration features a larger mainsail and a smaller, non-overlapping headsail, which greatly simplifies tacking and reduces the physical effort required by shorthanded crews.
Sailing Performance & Handling
On the water, the Sun Way 28 CB delivers a lively and responsive feel that betrays its racing pedigree. With a Displacement-to-Length (D/L) ratio of 206.79, the boat sits firmly in the moderate displacement category. It possesses enough physical mass to carry its momentum through a light coastal chop, preventing the boat from stalling out during tacks, yet remains light enough to accelerate quickly in a puff. This performance is supported by a Sail Area-to-Displacement (SA/Disp) ratio of 17.48, indicating a moderately powerful sail plan that performs very well in light-to-moderate air. Because of the fractional rig design, upwind work is balanced and highly controllable, though downwind performance in light air will benefit significantly from flying an asymmetric spinnaker or gennaker to compensate for the smaller standard jib.
With a Capsize Screening ratio of 2.19, the Sun Way 28 CB features a relatively wide beam of 9.81 feet relative to its displacement. This wide beam translates to excellent initial "form stability," meaning the boat heels to a certain angle and then stiffens up quickly, reassuring novice sailors and keeping the cabin relatively level in moderate winds. However, this ratio also indicates that the boat is designed for coastal and near-shore cruising rather than crossing oceans, as its ultimate self-righting capabilities are less than those of narrower, heavy-keeled offshore cruisers of the same era.
The Comfort Ratio of 17.06 indicates that the Sun Way 28 CB will have a quick, lively motion in a seaway. Because of the relatively flat forefoot design inherited from Tony Castro’s racing hulls, the boat can be prone to slamming or pounding when driven hard directly into short, steep head seas. Falling off a few degrees to crack off the sheets generally softens the ride. The twin rudders on the CB version are a major handling advantage; they provide phenomenal traction on the water and make the helm feel exceptionally light and positive. Even when over-canvased on a reach, the boat resists the urge to broach, as the leeward rudder remains fully effective.
Known Issues & Triage
Decades after leaving the factory, several specific areas of the Sun Way 28 CB require close inspection and preventative maintenance:
- Centerboard and Pivot Assembly: The cast iron stub keel houses a pivoting fiberglass centerboard. Over time, rust can scale up inside the centerboard slot, constricting the cavity and causing the board to jam in either the up or down position. The pivot pin itself can wear, leading to lateral slop and an irritating "clunking" sound while at anchor or under sail. The lifting pendant—the line used to raise and lower the board—is prone to chafe and must be inspected and replaced periodically while the boat is hauled out.
- Headliner Sag: Like many French production boats built in the late 1980s and early 1990s, the foam-backed vinyl headliner used in the cabins and saloon is notorious for adhesive failure. As the foam backing disintegrates into a sticky, orange powder, the vinyl sags and pulls away from the fiberglass deck deckhead. Remnants must be scraped clean, and owners typically resolve this by gluing new marine-grade vinyl or installing thin wood batten panels.
- Plywood Bilge Support Delamination: The structural grid of the boat relies on fiberglass-encased plywood floor frames and stringers in the bilge. If freshwater leaks from the deck fittings, mast step, or portlights are allowed to pool in the bilge over several years, this water can penetrate the fiberglass encasement and cause the underlying plywood structure to rot or delaminate.
- Aft Cockpit Locker and Hull-Deck Joint: The large cockpit locker is spacious but can seal poorly if the rubber gaskets have degraded, leading to water intrusion into the aft cabin. Additionally, the mechanical fasteners along the aluminum toe rail at the hull-deck joint should be checked for leaks, which often manifest as damp spots behind the saloon cabinetry.
- Underpowered Engine Options: Some early Sun Way 28 models were shipped with a single-cylinder, 9 horsepower Volvo Penta (Volvo 2001) diesel engine. While adequate for flat canals, this engine is widely considered underpowered when trying to push a 5,732-pound hull against a strong tidal flow or a stiff headwind, making units equipped with the two-cylinder 18 horsepower Volvo Penta 2002 or Yanmar 2GM20 much more desirable.
Modernization & Upgrades
Many veteran owners have successfully modernized the Sun Way 28 CB to meet contemporary cruising standards, focusing on off-grid capability and improved handling:
- Repowering: Replacing an aging, raw-water-cooled Volvo Penta 2001 or 2002 with a modern, fresh-water-cooled diesel engine (such as a Beta Marine 14 or 20, or a Yanmar 3YM20) is a highly effective upgrade. These modern lightweight diesels offer superior fuel efficiency, reduced vibration, and high-output alternators to keep domestic battery banks charged.
- Electrical System and Lithium (LiFePO4) Conversion: The generous lockers beneath the saloon settees and the cockpit make the Sun Way 28 an excellent candidate for a modern electrical refit. Owners frequently install a 200Ah to 300Ah Lithium Iron Phosphate battery bank paired with a high-efficiency smart charger and a DC-to-DC charger from the engine alternator. Adding flexible solar panels on the coachroof or on a small stern gantry provides sustainable power for 12V refrigeration and modern electronics.
- Running Rigging and Deck Hardware: Upgrading the centerboard lifting system by replacing the old polyester rope pendant with low-stretch Dyneema dramatically increases reliability and reduces the effort required at the cabin-top winch. Leading all halyards, reefing lines, and the centerboard control line back to the cockpit via modern deck organizers and spinlocks makes the boat incredibly easy to sail single-handed.
- Asymmetric Spinnaker Bowsprit: Installing a small, removable bowsprit on the foredeck allows owners to fly a modern asymmetric spinnaker or a Code Zero sail. This upgrade significantly improves downwind performance in light air, resolving the inherent downwind sluggishness associated with the small, fractional headsail.
The Verdict
The Jeanneau Sun Way 28 CB remains one of the most intelligently designed, high-volume pocket cruisers of its era. For sailors seeking a budget-friendly coastal cruiser capable of sneaking into knee-deep waters, navigating shallow channels, and taking the ground in tidal bays, the combination of a lifting centerboard and twin rudders is tough to beat. While buyers must be prepared to tackle age-related issues like sagging headliners or centerboard maintenance, the structural integrity of the solid GRP hull and the brilliant space-planning of Tony Castro make this model a highly rewarding platform for modern coastal adventures 6 9.
