The Bianca 28, a hallmark of Danish maritime craftsmanship from the mid-1970s, represents a refined evolution of the Quarter Tonner racing philosophy tailored for family cruising. Designed by the esteemed duo Paul Elvstrøm and Jan Kjærulff, the model was initially launched as the Bianca 26 before being marketed as the Bianca 28 to reflect its overall length more accurately. Produced by Bianca Yachts in Rudkøbing, Denmark, between 1974 and 1981, the boat gained a reputation for its robust build quality and elegant, slender lines typical of Scandinavian designs of that era. With approximately 400 to 500 units produced, it remains a common sight in Northern European waters, prized for its ability to balance competitive speed with the structural integrity required for Baltic coastal passages.

Sailing Performance & Handling
The Bianca 28 is characterized by a high ballast ratio—approximately 41%—which lends the vessel significant stiffness and a reassuring sense of stability in a blow. Its hull features a relatively narrow beam by modern standards, a design choice that prioritizes upwind efficiency and a smooth motion through choppy seas. Under its masthead sloop rig, the boat is known for having a "big boat" feel, tracking reliably thanks to a rudder mounted on a partial skeg, which offers a compromise between the maneuverability of a pure fin keel and the directional stability of a full-keel cruiser.
Owners frequently report that while the boat can be somewhat under-canvased in light winds (with a Sail Area/Displacement ratio in the mid-15s), it excels when the breeze freshens. It is particularly noted for its sea-kindliness; it does not slam into head seas but rather slices through them. The Elvstrøm influence is evident in the cockpit ergonomics, which are optimized for efficient sail handling, making it a popular choice for shorthanded sailors who appreciate a boat that can be pushed hard without becoming unruly.
Interior Comfort & Variations
For a 28-foot vessel of its vintage, the Bianca 28 offers a surprisingly functional and warm interior, traditionally finished in high-quality teak. The layout is a classic arrangement for a coastal cruiser of this size: a V-berth in the forepeak, a compact head (marine toilet) located between the saloon and the forward cabin, and two longitudinal settees in the main saloon that double as berths. A notable feature is the presence of a quarter berth to port, tucked behind the navigation station, providing a total of five berths.
Variations between the early "26" and the later "28" models are most visible in the fenestration; the original 26 typically featured a single long window on each side of the coachroof, while the 28 transitioned to two distinct windows per side. The galley is generally located to starboard and is equipped with a gimbaled stove and a small sink, though space is at a premium. Headroom is approximately 5'9" (1.75m), which is respectable for a performance-oriented 28-footer but may feel restrictive for taller crew members during extended stays.
Known Issues & Buyer’s Checklist
Prospective buyers should approach a Bianca 28 with a focus on age-related maintenance, specifically regarding the drivetrain and deck integrity:
- Original Engine Performance: Many units were originally fitted with the Yanmar YSE8 or YSM8 diesel engine. These 8hp units are often considered underpowered for the boat's 2.3-ton displacement, particularly when fighting tide or heavy head-seas. Check if the engine has been repowered with a more modern 10–15hp twin-cylinder unit.
- Deck Core and Hardware: Like many Scandinavian boats of this era, the deck utilizes a balsa or foam core. Inspect for "soft spots" around high-load areas such as the mast step and stanchion bases, where water ingress can lead to delamination over decades.
- Window Seals: The elongated windows of the Bianca 28 are a known point of failure. Look for evidence of wood staining on the interior teak, which indicates leaking seals that require re-bedding or replacement of the acrylic panes.
- Standing Rigging: Given that many of these boats are still campaigned in club races, the masthead rig should be carefully inspected for hairline fractures in the chainplates and fatigue in the wire terminals.
Community & Resources
The Bianca 28 enjoys a dedicated following, particularly through the Bianca Club, an organization based in Denmark that provides technical support and hosts rallies for owners of all Bianca models. While no longer in active production, the lineage of the 28 lives on through its larger siblings, such as the Bianca 320 and 360, which followed the same design language of high-performance cruising.
The Verdict
Pros:
- Exceptional Build Quality: Hand-laid GRP and fine Danish joinery ensure the boat ages gracefully.
- Stiff and Predictable: High ballast ratio makes it a safe, dry sailer in heavy weather.
- Timeless Aesthetics: Slender, low-profile lines that avoid the "boxy" look of modern high-volume cruisers.
Cons:
- Light Air Sluggishness: Requires a large genoa to perform well in winds under 8 knots.
- Tight Galley/Head: Modern sailors may find the 2.6m beam restrictive compared to newer wide-stern designs.
- Underpowered Auxiliaries: Original 8hp engines are often inadequate for modern cruising demands.
