History and Design

Albin Marine, initially established as Albin Motors in 1899, transitioned from marine engine production to boat building in 1929, eventually focusing on serial production of fiberglass boats from 1966 onwards. The Delta 31 emerged during a period when Albin Marine had already solidified its reputation for durability and thoughtful design, appealing to a wide range of mariners. The Delta 31, also known as the Albin Delta, was designed by Peter Norlin as a cruiser-racer, reflecting a design philosophy aimed at combining sporty performance with comfortable cruising capabilities. Its production run from 1983 to 1986 saw 300 hulls completed, contributing to Albin's respected sailboat range which included other notable models like the Albin Vega and Albin 25. There is no information to suggest significant variations or MkI/MkII versions during its production run.

Sailing Performance and Handling

The Albin Delta 31 is recognized for its responsive and sporty sailing characteristics. With a total calculated sail area of 436.45 sq ft and a displacement of 8598 lbs, its Sail Area to Displacement ratio (ratio_sa_disp) is approximately 19.5, suggesting good performance in lighter winds. Its Ballast to Displacement ratio (ratio_bal_disp) is around 0.41, indicating a relatively stiff and stable boat, capable of standing up to more wind. The Displacement to Length ratio (ratio_disp_lwl) is approximately 229, placing it in the medium-light displacement category, which aligns with its cruiser-racer designation, offering a good balance between speed and seaworthiness. The boat is built with a fin keel and a spade rudder, which are known to provide splendid maneuverability and quick response to sail trim. Anecdotal evidence suggests the Delta 31 is a fun boat to sail and handles well in various sea states. Its generous sail plan is noted to deliver excellent light-air performance.

Accommodations and Layout
