Just to recall, this piece was published back when they still thought nautical terms and technology had been passed on from German speaking people to the Sa'ami.
We now know it was the other way around with even some grammatical practices in the Sa'ami languages having found themselves firmly lodged in the German languages.
These "sewn boats" are actually plank boats curved against a sort of proto-frame, and tied in place through holes drilled at regular intervals.
The discovery sites of the most ancient extant boats occur in upland sites throughout Scandinavia. Total wrecks are found in the estuaries. The implication is that the boats were built in the mountains, used, sold down river, and finally put to work in the Actic Ocean, a very unforgiving environment.
The fundamental hullshape and ribbing designs are translated to the early Indo-Europeans (aka Vikings) at some period of time. The boats were scaled up and turned into the typical seagoing ships used by the Vikings.
This piece gives a good idea of what might well have been an Ice Age boat design. The writer, though, seems to think this design was the step up from dugouts ~ even though there were no trees large enough to be "dug out" in the Sapmai!
One important point for archaeologists should be that improved boat designs in Scandinavia came about first at an early age INLAND for use on wild glacier rivers and streams. Those boats were then modified for use in the far gentler ocean.
