Bianca 107 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Bianca 107 is characterized by a high ballast-to-displacement ratio of approximately 45%, which contributes to exceptional stability and a stiff, upright sailing posture. Its fin keel and spade rudder configuration, coupled with a displacement of roughly 4,800 kg, allow the boat to track reliably while remaining responsive in light air. Most hulls were equipped with a 7/8 fractional rig, a design choice by Jan Kjærulff that allows for precise mainsail trimming and easier handling for shorthanded crews compared to the large, overlapping genoas of masthead rigs.

The boat’s technical ratios suggest a hull that is optimized for windward performance. With a sail area-to-displacement ratio hovering around 19, the 107 feels lively and accelerates quickly out of tacks. Owners frequently report that the vessel feels "locked in" when sailing upwind, a trait inherited from Kjærulff's background in competitive racing designs. While the narrow beam (3.2 meters) limits initial stability compared to wider modern designs, the deep ballast ensures it handles heavy gusts with composure rather than excessive heeling.

Interior Comfort & Variations

The interior of the Bianca 107 showcases traditional Scandinavian joinery, utilizing high-grade teak and a thoughtful layout that was considered modern for its era. The arrangement typically features a double V-berth forward, a central saloon with a folding table, and a notably large aft cabin that extends beneath the cockpit—a significant feat for a 35-foot boat of this vintage. A distinctive feature of the 107 is the placement of the head on the port side immediately adjacent to the companionway, which provides easy access for the crew while on watch.

Unlike many of its Mediterranean contemporaries, the Bianca 107 did not feature multiple cabin variants (such as a four-cabin version); instead, the yard focused on a singular, high-quality two-cabin layout. However, the model is often discussed alongside its "siblings" from the same design era, such as the larger Bianca 111 and the slightly smaller Bianca 320. While these boats share the same design language, the 107 is often cited as the "sweet spot" in the range, offering a balance of manageable size and genuine offshore capability.

Known Issues & Buyer’s Checklist

Prospective buyers of a Bianca 107 should focus their inspections on several age-related technical areas common to high-performance Danish cruisers of the 1980s:

• Teak Deck Integrity: Many 107s were originally delivered with high-quality teak decks laid in bedding compound. Over four decades, these decks may suffer from thinning or failing sealant. Inspection of the core for moisture ingress is critical, as many owners have opted to replace original teak with synthetic alternatives or non-skid paint.
• Rudder Bearings and Stock: The spade rudder is a high-load component. Check for excessive play in the bearings and signs of corrosion on the rudder stock, especially on boats that have spent significant time in saltwater.
• Chainplate and Rigging Tensioners: The 7/8 fractional rig places significant tension on the backstay and shrouds. Inspect the hull-to-deck joints near the chainplates for stress cracks or evidence of movement.
• Engine Service History: Original models were typically fitted with Yanmar or Volvo Penta engines (often the 2GM20 or 3GM30 series). Buyers should verify the condition of the saildrive seal, as these require replacement every 7–10 years depending on manufacturer guidelines.

Community & Resources

The legacy of the Bianca 107 is maintained through a dedicated community of Northern European sailors. Technical documentation and historical context are frequently curated by the Bianca Yacht Club, which serves as a repository for owners looking for original blueprints or advice on restoration. In Denmark and Germany, the model is a frequent participant in classic yacht regattas, where it continues to hold its own against more modern designs.

The Verdict

Pros:

• Excellent windward performance and high stability (45% ballast ratio).
• Superior Scandinavian build quality with high-end teak interiors.
• Timeless, elegant hull lines that age better than wider modern cruisers.
• Efficient 7/8 fractional rig is easy for a couple to manage.

Cons:

• Narrow beam results in less interior volume and narrower side decks than modern 35-footers.
• Original teak decks are often at the end of their service life.
• Limited freshwater and fuel capacity (typically around 100L and 60L respectively) restricts long-range autonomy.
