Sefyr is a boat transport company that mainly runs in the western archipelago of Åland.

Sefyr is anchored in Käringsund's guest harbor in Eckerö in the western part of Åland, about 30 minutes drive from Mariehamn. You can easily reach us with the Eckerölinjen ferry from Grisslehamn in Sweden. It is also possible to come between two of the Eckeröljens tours and get a full day at sea with us.

Sefyr's main destinations and excursions are the Märket lighthouse, seal safari and Signilskär. But we can also offer a one way journey from "A to B" and the possibility of tailoring your own adventure.

Contact me with your wishes and I'll do everything I can to make them reality


Sefyr is driven and steered by me Fredrik Holmström, born and raised in Jomala in Åland. Since childhood I've spent my summers in Eckerö, on the family cottage village of Holmström's cottages.
Therefore, I am well knowed with the sea around Eckerö.

I'm a educated chef and mate and have among other things, worked on the large ferries in the Baltic Sea.

My greatest interests are hunting and fishing. But of course I spend most of my time with my two daughters and spouse.


M/S Sefyr is of the type Watercat 1101 built with aluminum. The boat is about 12.5 m long and 3.5 m wide. The engine is a Scania 500 hp with water jet, cruise speed 17 knots and approved for a maximum of 12 passengers. The boat is inspected and CE-marked.


Of course, we have life jackets and life rafts for everyone on board.
