The Bianca 320 represents the final chapter of the original Danish shipyard’s prominence, serving as a refined bridge between the pure racing pedigree of the Elvstrøm-Kjærulff era and the more substantial cruising needs of the late 1980s. Designed by Jan Kjærulff and launched in approximately 1987, the 320—sometimes marketed as the Bavanca 320—inherited the sleek, "spooned" bow profiles and efficient underwater lines seen in its larger siblings, the Bianca 107 and 111. Built in Rudkøbing, Denmark, the vessel is a quintessential Scandinavian cruiser-racer: narrow enough for efficiency in the Baltic chop but significantly more voluminous than the shipyard’s earlier, more Spartan designs.

Sailing Performance & Handling

At its core, the Bianca 320 is a performance-oriented hull that prioritizes stability and upwind efficiency. With a ballast-to-displacement ratio approaching 47%, the boat is remarkably stiff, a trait that allows it to carry its sail plan longer than many modern light-displacement competitors before requiring a reef. According to the design history documented by the Bianca Yacht service yard, Jan Kjærulff focused on creating boats that offered a "soft motion" in heavy weather, a characteristic achieved through the 320’s moderate displacement-to-length ratio of approximately 267.

Under sail, the boat typically utilizes a 7/8 fractional rig, though masthead variants exist for specific markets. The fractional setup allows for easier tuning of the mast bend to flatten the mainsail in building breezes, while the high ballast ratio ensures the boat remains "on its feet" when pressed. Handling is generally described as direct and rewarding, particularly in hulls equipped with the standard tiller steering, which transmits the rudder’s feel without the mechanical friction of a pedestal system.

Interior Comfort & Variations

The interior of the Bianca 320 is defined by the high-standard wood joinery typical of Danish yards from this era, utilizing warm mahogany or teak finishes. The layout is a classic two-cabin configuration: a forward V-berth and an enclosed aft cabin to port, which provides considerably more privacy than the open-quarter berths found on earlier Bianca models. The salon offers approximately 1.82 meters (just under 6 feet) of headroom, a generous dimension for a 32-foot boat of its vintage.

Sibling models built during this period followed a similar design language. While the Bianca 320 was the entry-level offering for the "modern" line, it shared structural DNA and aesthetic cues with the Bianca 107 (35 feet) and the Bianca 111 (37 feet). These siblings offered the same "round-bilge" hull form and balsa-core construction but provided additional cabin variants. The 320 remains a favorite for its "contemporary" look even decades after production ceased, as noted in editorial reflections by Mers et Bateaux.

The Bianca 320 is frequently cited in European maritime journals as a "coup de cœur" (favorite) for its aesthetic balance and build quality. Its legacy is preserved primarily within the Scandinavian sailing community, where the shipyard’s history is celebrated by the Bianca Club, a technical association dedicated to the preservation of the brand's fleet. While it did not achieve the massive production numbers of the legendary Bianca 27, it remains a respected participant in Baltic regional regattas.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Bianca 320 with a focus on its composite construction and high-load areas:

  • Deck and Hull Core: The 320 uses a balsa-core sandwich construction for both the hull and deck. While this provides excellent thermal and acoustic insulation, any unsealed deck hardware or impact damage can lead to water ingress and core rot. A moisture meter and percussion test are essential during a survey.
  • Mast Step and Compression: Given the high tension required for a fractional rig, the mast foot and the supporting structure in the bilge should be inspected for signs of compression or "spider-web" cracking in the gelcoat.
  • Saildrive Diaphragm: Most 320s are powered by a Yanmar 2GM20 with a saildrive. The rubber hull diaphragm (collar) has a recommended replacement interval of 7 to 10 years; many original units may still be in place and represent a critical maintenance item.
  • Window Leaks: The perspex windows on late 80s models are prone to bedding failure, leading to minor leaks that can damage the interior woodwork if left unaddressed.

Community & Resources

The most prominent technical resource for the model is the Bianca Club, based in Denmark, which maintains archives for the various Kjærulff and Elvstrøm designs. Additionally, the Bianca Yacht yard in Rudkøbing continues to operate as a specialized repair and brokerage facility, providing a rare level of continuity for owners seeking original specifications or structural advice.

The Verdict

Pros:

  • Exceptional Stability: A 47% ballast ratio makes for a very safe, stiff, and forgiving platform in a blow.
  • Danish Craftsmanship: High-quality interior joinery and balsa-core insulation provide a "ship-like" feel superior to mass-market production boats.
  • Timeless Aesthetics: The spooned bow and balanced proportions have aged significantly better than the "wedge" hulls of the early 90s.

Cons:

  • Maintenance Intensive: Sandwich-core hulls require vigilant sealing and professional inspection to avoid delamination.
  • Limited Headroom: While reasonable for its size, sailors over 6 feet may find the 1.82-meter clearance tight in the forward cabin and heads.
  • Niche Market: Finding replacement parts for shipyard-specific hardware may require sourcing directly from Denmark.
