Welcome to Sonwik Yacht Harbour, your starting point for the Western Baltic Sea.

Located in the Flensburg Fjord you have the amenities of the picturesque city of Flensburg, but also a quiet and protected place for the night in our marina.

With more than 400 berths for boats up to 25m length we can offer you a relaxed stay. Our 4 Star Blue Star IMCI certified Marina has a minimum depth of 6m and is equipped with swimming pontoons and finger piers, free use of showers and Wi-Fi, restaurants, a café and a sailmaker. At our self-service diesel fuel station, which is open 24/7, you get marine diesel, i.e. pure diesel without bio content. You can book your berth in advance via dockspot.com and pay via Go Marina.

If you need service for your boat, with our Flensburger Yacht-Service we offer you full service. From our repairs, refits, engine and rig service, winter storage – you name it, we have it.

We can lift boats up to 3 t directly at the marina. For boats up to 18 t. we have a crane at the Yacht-Service. There you also find a 300 m² chandlery for clothes and all your spare parts and equipment needs.

You can easily travel to the inner city of Flensburg by bus, ferry or you just take a stroll along the seaside. Here you can discover little medieval streets, restaurants and bars or find a lot of nice shops for shopping.

The Flensburg Fjord itself is a great cruising ground but is also the entrance door to Denmark with its hundreds of lovely islands. Just come and see for yourself!
