Interior and Sleeping Arrangements

Inside, the Boström 31 accommodates four people, with two fixed berths and two additional berths. The interior is functionally designed but shows signs of aging. The cockpit is equipped with seating finished with synthetic teak, which adds to the comfort while sailing or at anchor. The boat has a manual toilet with direct discharge to open water. 

Sail Plan and Rigging

The Boström 31 is rigged with an aluminum mast and has four sails: a jib, genoa, mainsail, and storm jib. The condition of the sails is described as reasonable. The sail plan is suitable for various weather conditions, with the boat characterized by direct steering and good upwind performance. These features make the vessel suitable for sailors who value maneuverability and course stability.

Motorization and Electrical Installation

The boat is equipped with an inboard diesel engine from the brand Yanmar, type 2MG20, with an electric start system. The engine is connected to an alternator and supported by two batteries. There is a provision for shore power connection, as well as a battery charger. This combination allows for sufficient power supply during longer trips.

Equipment and Safety

On deck, the Boström 31 is equipped with a swim ladder, guardrail, fenders, and lines. The cockpit is self-draining, which contributes to safety in rougher weather. For emergencies, a lifebuoy and a life raft are available (inspection required). The electric bilge pump provides extra security in case of water ingress. 

Maintenance and Condition

The last time the boat was taken out of the water for maintenance and antifouling treatment was in 2025. A leak at a window has been reported, which requires attention. The condition of the boat is described as reasonable, meaning there may be some points that need maintenance or replacement. The antifouling below the waterline is blue, while the upper deck is finished in white.

Usage and Sailing Area

The current owner has mainly used the Boström 31 for day trips on inland waters and lakes. The boat is suitable for recreational use and offers sufficient comfort for short stays on board. The direct steering and ability to sail close to the wind are noted as characteristic sailing properties.

Summary

The Boström 31 is a classic polyester sailing yacht with functional equipment and a sail plan suitable for various conditions. With a length of just under 10 meters and a relatively deep keel, the vessel offers stability and course stability. The combination of a Yanmar diesel engine, electrical provisions, and a self-draining cockpit makes the vessel suitable for both novice and more experienced sailors looking for a sailboat for recreational use on inland waters.
