Perhaps "tub trawler", which means longliner with the separate segments put into tubs, line coiled (or better, flaked down flat) in the center, hooks set around the rim, then set out turning the tub if needed to have the hooks clear without tangling. Difficult to describe, I guess. Never used that method myself. Lots of other commercial fishing, though, including many years of actual "trawling" with nets of various type, some clip-on long-lining like was seen in the movie Perfect Storm (but not for swordfish, I netted those things years ago, under California gill net permit).
Would a 44 foot shrimper be a trawler? My father made one out of a hull he bought out of a farmer’s field, after Hurricane Carla.
Wonder if the reporter meant Troller instead of Trawler.
