About the BIANCA 27
Based on the earlier PITI. Said to be the first series-produced Danish sailing yacht in fiberglass.
Designed by Svend Aage Christensen and built by Bianca A/S in Denmark, the Bianca 27 is a classic full-keel sloop with a production run of 604 hulls from 1964–1975. Its substantial displacement of 7165.0 lb and full/long keel configuration define its heavy, stable character, making it a distinct choice among 1960s European designs.
- Best for:
- This boat suits coastal cruisers and budget-conscious buyers seeking a robust, traditional layout, as evidenced by the high frequency of dodger and cockpit canvas upgrades. Its manageable size and heavy displacement also appeal to those prioritizing stability and comfort over high-speed performance.
- Bluewater capability:
- With a capsize ratio of 1.66 and a comfort ratio of 31.03, the Bianca 27 offers good offshore stability, though its age and specific keel attachment vulnerabilities require careful assessment for extended bluewater passages.
- Comparables:
- Comparable boats include the O'Day 27 and Pearson 27, which share similar era, displacement, and full-keel characteristics. These vessels offer similar coastal cruising capabilities and traditional sailing dynamics, making them direct competitors in the used market.
