Finnish designer Matti Pulli created this elegant 31-footer during the early 1980s as a sophisticated coastal cruiser with surprising offshore capabilities. Built by Länsivene Oy in mahogany construction, only eight examples were produced between 1982 and 1984, making the Mp 31 a rare find in today's market. The design showcases classic Scandinavian sensibilities with its moderate displacement of 6,614 pounds and well-balanced proportions. The fractional sloop rig with 473.61 square feet of sail area provides excellent performance in light to moderate conditions, while the fin keel and spade rudder configuration delivers responsive handling and good upwind ability. With a waterline length of 24.61 feet, the boat achieves a respectable hull speed of 6.65 knots. The Mp 31's comfort ratio of 16.81 indicates this is primarily a performance-oriented cruiser rather than a heavy offshore passage-maker, though the reasonable capsize screening value of 2.24 suggests adequate stability for coastal and near-offshore sailing. The mahogany construction reflects the high-quality craftsmanship typical of Finnish boatbuilding, though potential buyers should carefully evaluate the condition of the wood and any necessary maintenance requirements given the boat's age.
