Seafinn 411 for sale


We have reached an age where it is about time to get an easy apartment ashore, so our lovely long-distance boat and home for the last 8 years is for sale.

Boat for long-distance and liveaboard

The boat has had a total of three owners, all three owners have been on a trip to the Mediterranean with the boat. As it only has a draft of 1.60 m (full last), it is suitable for sailing the inland waterways through the French rivers and canals, but at sea down the European west coast is also an option.

The previous owner was told by a surveyor that the boat (after extra examination of the mast) could be insured for a trip across the Atlantic, but if you dream of circumnavigating, there are better boat types. A Seafinn 411 is a motor yacht that sails really well with a little slack on the sails. It sails well close-hauled, but in headwind we have nearly always used motor + close-hauled mainsail, which provides a comfortable sailing.

The boat is well equipped with spare parts for the engine, so common small repairs can be done on site (by yourself or the local mechanic).

In addition, both the previous owners and we have been liveaboards. For that purpose the boat is optimized for max. three people, but in summertime it has worked well as a holiday home for 6-7 people in several weeks.

Side cabin (depot and washing machine)

Here, e.g. folding bikes (can be included), base and mattress for making up a double bed in the salon, extra life jackets, cockpit cushions and everything else that needs to be kept dry! In addition, the washing machine goes through the upper bunk floor and stands on a plinth on the lower one.

If desired, the bunks can be re-established by removing the washing machine, replacing the cut section of the upper bunk bottom and making new mattresses.

The Seafinn boats have to some extent been self-adapted and perhaps also built in relation to the customer’s wishes. At some point, a standard version of the Seafinn 411 came out, for which there is also an old sales brochure. This is the version we have. There is only one side door in the wheelhouse, instead there is a staircase with a sliding hatch up to the aft platform. We really appreciate that, both during sailing and when we sit outside in good weather.

Compared to the original layout, rebuildings and additions have been made that make the boat even more suitable for living onboard.
