You mean like these??:
Most are second hand from, or newbuilt in Norway or Denmark. The difference is that they don’t have seining equipment.
Yes they do use pumps to bring the catch from the trawl bag to RSW tanks:
As do the seiners, as seen in the video linked in this article:

This should also explain how they manage to shoot the net without a skiff.
There do not appear to be a lot of manual work involved for the crew of 10.
PS> There are links to videos from different vessels and fishing methods as well.
Maybe a Moderator could move the last few posts to a different thread, since they are not about boat handling??
