It’s been a great week in Göteborg – Eva-Britt has been the most fabulous host, Göteborg is a great town and of course the islands are amazing. not to mention to wealth of information that has been obtained – awaiting translation, of course.
The great lump of amber I am holding is wonderful bit if treasure form Nils Eriksson’s past, one brought up in a net from the bottom of the Baltic. Nils was one of several stops, including visiting Sven-Olof Larsson on the island of Hönö, a very much clear-minded gentleman in his 90’s. Another useful visit (complete with a free book) was with Lennart Bornmalm, who has contributed to several book about the fishing community of Bornhuslan. Last but not least, a visit to Stig-Rune Yngvesson – son of my primary patent applicant, Yngve Bernhardsson. A wealth of information and a handful of documents – prefect and of course a welcome conclusion to a week in Göteborg!

I’m heading of to catch a ferry to Göteborg – I shall be spending a week there with the lovely Eva-Britt Larsson, form the Swedish paper Yrkesfiskarna. We shall be adventuring forth to chat to some fishermen in Göteborg and on the islands nearby – it’s certainly something to look forward to, as I have no doubt that I shall be getting to the real roots of pelagic trawling!
Patent no. GB598097
I took me a long time to realise that this was the oldest patent I had for a functioning pelagic trawl – I had misfiled it under headline floats, for some silly reason. But the niggling feeling that I was missing a piece and my Dad’s recollection of the first pelagic pair trawl had been Swedish got me to searching my database again – and up popped Yngve Bernhardsson. According to his patent, filed September 20th 1945, he was a Swedish national living on Fotö, near Göteborg in Sweden.
His patent is a short affair, 3 pages, with less than 1 and a half given over to explanation. For your pleasure I include his diagrams. He describes his trawl as having a ‘substantially rectangular mouth’, ‘tow-lines fastened at each corner of the mouth’ and that the two towing vessels ‘should be at a distance form each other that the mouth will be strained in a horizontal direction’. There is a complex affair of float and weights, which are interlinked and depicted in the diagram – apparently with some adjustable features to vary the size of the mouth. where I fell down was the lack of specificity – he, or rather the agency no doubt translating and typing up – does not mention at what depth the gear is to be deployed, or even any measurements. No doubt this is why it got filed under floats and bottom trawls.
On the upside, now I get to go through every patent and double check their classification… And that Bernhardsson beats Larsen by two months with the patents that I have at hand.
