I don’t know, but we got a Dutchman here that may explain the “Flyshooter”.
“Twinrigger” presumably means that they have to trawl nets. Whether they can tow both simultaneously is another question. (??)
I know that larger bottom trawlers is set up with two trawl nets, but they shoot one while the other is on the way up with catch to ensure they don’t miss any “on bottom time”.
(Kraken to the rescue??)
PS> To me Pelagic and Midwater trawling is one and the same, but different from bottom trawling.
That’s a flyshooter, not a trawler. They deploy the buoy (shown in the photo) then stream out a long Seine net rope, then alter course and deploy the net across the second leg of the triangle and alter again back towards the buoy paying out another leg of rope. They then pick up the buoy and pull both ropes in as they slowly steam ahead, the ropes draw together and any fish in the triangle is caught in the net.
A twin rigger is a trawler what tows two nets. The inboard end of each net has sweeps up to a clump which is on its own warp. So you have warp, door, sweeps, net, sweeps, clump (warp) sweeps, net, sweeps, door, warp, if that makes sense.
The scandalous thing about the picture is that the boat is Dutch owned, managed and crewed yet registered in the UK and catching fish against the UK quota. There’s heaps of them in the southern North Sea and will only be more following brexit.

1986 according to the internets, and very similar vessels are still built… The severely rusted patch is where the beam nets come on board. They are mainly used for catching flatfish, prawns and other beasties that hang out on the seabed.
More recently Dutch fishermen have switched to pulse-gear which uses electrical currents rather than chains in front of the net to scare the fish off the seabed. The advantage is that it reduces drag and thus fuel consumption, and causes less damage to the seafloor. Only problem is that the changes in gear were covered under an experimental permit that the NL government handed out to pretty much anyone in the expectation that the rules would change permanently - and now the experiment is over and the EU is having none of it (mainly because of French resistance as they’re using older methods).
It says Dutch and UK boats, but as mentioned elsewhere the UK boats are just reflagged for quota reasons.
This colourful little beauty is a “killing machine”. It collects live fish directly from floating cages and transport it to the processing plant.
As an additional service the fish is stunned, killed and bled out in chilled water while enroute.This is all done as humanely as possible to ensure that the fish is not stressed, thus maintaining best possible quality of the end product.
Of course carried out by machine and computer controlled, not manually.
they shut us down pairtrawling in the northeast,codfishing anyway, in the mid 90s. we got too good at it. same with palegic tuna pair trawling, was great going for a few years, but it too was shut down…
