Re: What Swedish boat is this?
I have sometimes seen an old black and white picture of a quite similar boat used as a ship's boat by the Swedish (or was it Danish) navy. My memory may fail though but it looks somehow known. I have seen in person a quite similar but square sterned boat which was said to be a late 19th century Swedish navy ship's boat. So something naval it definitely is.
That oarlock system was common on naval ship's boats of all sizes. A system similar in principle was even used on fishing boats around here.
