COMMANDER 31 (BIANCA)

About the COMMANDER 31 (BIANCA)

Designed by Knud E. Hansen & Jan Kjærulff and built by Bianca Yachts, the Commander 31 is a classic fractional sloop with 150 hulls constructed between 1969–1976. This Danish cruiser is characterized by its 30.7 ft LOA, 7715.0 lb displacement, and 3.7 ft max draft, offering a balanced blend of performance and comfort with a comfort ratio of 26.62.

Best for:

This boat suits coastal cruisers and weekend sailors who prioritize a comfortable, stable platform with a 22.0 ft LWL and 8.83 ft beam. Its moderate displacement and fractional rig make it manageable for couples or small families seeking a reliable, classic cruising experience.

Bluewater capability:

With a capsize ratio of 1.79 and a D/L ratio of 323.46, the Commander 31 is primarily designed for coastal cruising rather than heavy offshore passage-making. While its fin keel and 3525.0 lb ballast provide adequate stability for protected waters, its relatively light displacement and age suggest it is best suited for shorter offshore trips with careful provisioning.

Comparables:

Comparable boats include the Valiant 32 and O'Day 32, which share similar production eras, fractional sloop rigs, and moderate displacement profiles. These vessels offer similar coastal cruising capabilities and interior layouts, making them direct competitors for buyers seeking 1970s Danish or American cruisers.
