Figure 4. The engraving of Kodeljevo castle in Ljubljana (top and middle), shows the typological appearance of the boat. But the copper engraving makes it extremely difficult to confirm that all the relevant elements of the construction of a drevák are present (Thurn an der Laybach; Valvasor 1689: 264). Two different images of Lake Cerknica (bottom). The left image is highlighting the human activities (fishing, etc.) on the field during the flooded Lake period. On the right image, they have presented bear and deer hunting as well as mowing meadows. 'Derberanderliche Czircknitzer See' (Brown 1696: 190).
Figure 6. Nailing techniques are the same in the case of a ship from Altenwörth as notranjski drevák. The only difference is that in the case of the ship from Altenwörth (Reitmaier 2008: fig. 81) the nailing process was done from the inner side of the boat, and in notranjski drevák from the outside (top and middle). Bottom right: Comparison of flat-bottomed Roman ships from the Lipe, Sinja Gorica, Yverdon-sur-Bains, Woerden, De Meern and Sisak (Erič et al. 2014: fig. 31). Bottom left: On the image of a Roman ship from the 1st century AD from the Kupa River in Kamensko near Karlovac (Croatia) the open L-shaped cross-section of chine-girder is clearly visible.

In 2015 the Slovenian Register of Intangible Cultural Heritage was enriched with the description of how to make a characteristic extended logboat, called a drevák. Its presence can be traced to the 17th century when the first written sources witness its use in the basin of the Ljubljanica River—a region of karstic fields (called ‘polje’) in Notranjska. The boat is made from spruce and is still used for fishing, rescuing, recreation and heritage promotion. The drevák is made from C-profiled chine-girders and embedded with one to three bottom planks, which are no more than 70cm wide. The flat central bottom rises towards the bow and stern where it rounds into an ellipse. Based on iconographic sources and boats still in existence, we can gather that the drevák was between five and 12m long, but, unlike similar boats, it has no knees or floor timbers. Until recently, it was believed that this type of logboat originated in the basin of the Po River in Italy. However, new research into the Roman Age shipbuilding tradition through excavating a shipwreck in the Ljubljanica River in Slovenia and another in the Kupa River in Croatia, provided a reason to reconsider its origin. In Europe, there is wide-ranging evidence of boats constructed similarly to the drevák; the closest can be found in Krefeld-Gellep II in Germany, which is a logboat from the early Middle Ages. During our research, we also found a surprisingly similar extended logboat in Lake Suwa near Nagano in Japan.
