It’s time to let the genie out of the bottle and make it public, we are moving to a bigger place (more about that later). We kind of knew this already when we left Sweden almost a year ago but we didn’t know where to and that it would come this soon.
The price of the boat has been lowered with € 2000 and is valid till we put her on the dry next week (week 19). It’s also possible to buy her without the wind vane and with regular batteries and a regular 5A CTEK charger instead of the 300Ah Lithium batteries and the 25A CTEK charger, that will cut another € 2000 each from the initial price of € 18500 lowering the total to € 12.500.
If you would like the wind vane then € 2000 is added to the price of the boat and the same goes for the 300Ah lithium batteries.
During the time we’ve been sailing we’ve realised that a few more feet here and there wouldn’t be a bad thing since we live on our boat 24/7 so the last few month we’ve been juggling different boats and weighing our options back and forth and the time has now come to bid farewell to our beloved B31 Mk2. At the time we’ve sailed her about 2000nm from Malmö down to A Coruña in northern Spain and we’ll keep sailing her till we either reach Greece or find her new owner whatever comes first. She is for sure a lovely boat that has been in the family since 1978 when she was built by my father so it is without doubt hard to put her up for sale.

If you ever sailed a B31 you already know that it is a sturdy 31 foot boat with a strong keel-stepped Seldén mast and with a V bolted fin keel, with 22 sturdy keel bolts over 175cm, and rudder on skeg. She that moves and feels like she’s way bigger than she actually is. The deep protected cockpit creates a safe sailing environment with high coamings gives great back support both when sailing or just chilling in the cockpit. Talking about the cockpit, all teak lockers in the cockpit has been replaces and renewed the last few years and are in very good condition.
Due to the weight ratio the B31 is a stiff boat, our keel is 1.8 tonnes of the boats 3.5 tonnes displacement. Even if she prefer 15-20 knots of wind she’ll still behave well in 30 knots of wind if asked and even above 40 knots she’s still safe and sound.
Since the B31 was sold as a “kit boat” the interior can sometimes differ quite a bit depending on the skill of the builder. This particular B31 was built by a skilled craftsman and has been maintained and taken care of by the same single owner since then, I bought the boat from my father (the one who built her) 2 years ago and upgraded the core electric system, installed LED’s and dimmable LED lights, solar panels, kitchen, heater, and some of the storage to ensure trouble free living onboard both in marinas and at anchor.
As you can tell our particular boat has been “slightly” upgraded since we planned to bring her far away from home. Some of the current configuration can be found in the table below, the prices are what we paid about a year ago and unless a possible buyer request otherwise everything below will come with the boat.

Beside everything above we also got a ton of spare parts, tools, small electrical heater, mooring lines, anchor lines, new halyards, small inflatable dingie with oars, cooking equipment, pots and pans, plates etc. As of now the boat comes with everything you need to live onboard and sail to the end of the world and back if you are up to it.
The B31 came with 2 engine options 8 or 12hp, this one got the YSB12 (12hp) engine. Even if you can motor along quite well with it its main purpose is to take you in and out of the marinas in a convenient way. The engine, that is freshwater cooled, has been taken care of with regular oil and filter changes during the years, the only thing it’s lacking at the moment is some fresh paint that we haven’t got around to take care of but at the end of the day it is the inside that matters.
The boat comes with fresh but not new sails. The furling genoa got a new UV-protection a few years back and both the genoa and mainsail has been reviewed by sailmakers before we left Sweden last year. Beside the regular sails we also got a spinnaker with pole.
The old mainsail track with traveller was replaced 2020 with new ones from Seldén to allow easy and convenient trimming
So what’s “missing” and what needs to be done next with the boat?
Let’s start with the “missing” parts:
– Since we use the wind vane when sailing we haven’t bought an autopilot.
– We haven’t really found any use for a radar either so there is none.
– We got no freezer either (the cooler is enough for us), however a spot that we now use as storage has been kind of prepared to install a freezer in if needed in the future.
– Windlass, since the anchor is only 15kg we haven’t got around to installing one. Oh, about anchors, we also got 2 extra anchors of 7 and 10kg.
What needs to be done with the boat:
Nothing really, but the next thing I would do when the boat is on the dry is to reseal the keel joint since the boat has been around for a few years.
Some pictures
So what will a complete “just move in and explore the world”-sailboat set you back? The current asking price is 18.500€ €12.500 or about 185.000sek 125.000sek with everything included except the wind vane and lithium batteries as stated above. She is located and ready to be sailed in Portimão Portugal.
She’s currently flying a Swedish flag (obviously) and since she’s before 1986 there are no VAT regulations but we do have all documentation since she was built with VAT defined as well just in case.
