The small province Blekinge in southeast Sweden actually has its own boat type. Specific for the type is the pentagonal transom that sits on the top of the stern. It has few but wide plankings and quite weak ribs. The entire boat hull should be built of oak. It is originally a rowing and sailing boat. Spritsail has been the most common sail, but for herring fishing far offshore, an asymmetrical square sail was used during the 19th century.

We do not know when it was created, probably in the 17th century, but in the 19th century it was almost alone as a boat type in Blekinge. It was built in different sizes between 11 foot to 45 foot, adapted for its various purposes. It was named after its use, such as garnbåt, vrakeka, sätteka, krokeka, frakteka, or just eka.

The coast's appearance has also affected the look of the boat. In western Blekinge with its open sea, the boat is more heavily built, in the east with its protective archipelago, it has more falling stem and slender materials. It has been used between the Kalmarsunds coast and the southern coast of Skåne.
