BOSTROM 31 MKII

About the BOSTROM 31 MKII

Same hull as BOSTROM 31 but with more freeboard and new deck.

The Bostrom 31 MKII, designed by Bruno Boström/Grandinsson and built between 1977–1984, is a classic Swedish cruiser known for its robust construction and comfortable accommodations. With a displacement of 7275.0 lb and a comfort ratio of 21.81, it offers a stable platform that balances performance with liveability, though specific hull production numbers are not definitively recorded in the source data.

Best for:

This boat is well-suited for coastal cruisers and couples seeking a comfortable, well-proportioned sloop for extended weekend trips or moderate offshore passages. Its manageable size and strong build quality also make it a viable option for experienced single-handers who prioritize safety and ease of handling over high-speed racing.

Bluewater capability:

With a capsize ratio of 1.87 and a displacement of 7275.0 lb, the Bostrom 31 MKII demonstrates strong inherent stability and seaworthiness suitable for offshore cruising. Its fin keel design and moderate sail area-to-displacement ratio of 15.82 suggest it is capable of handling open ocean conditions, provided the hull integrity is maintained.

Comparables:

Comparable vessels include the Hallberg-Rassy 31 and the Nauticat 31, as they share similar Swedish design philosophies, heavy displacement characteristics, and a focus on seaworthiness. These boats are often compared due to their overlapping production eras and reputation for being sturdy, safe cruisers with excellent interior layouts.
