An era of rapid technical development in vessel design began with the British factory trawler experiment in the late 1940s, which demonstrated the great advantage of large stern trawlers that processed their catch on board.
The krill-fishing operations are carried out with large stern trawlers using successfully midwater trawls, side trawls and conical nets.
The roll response for a medium-sized stern trawler is investigated in regular beam and longitudinal waves, at zero speed.
The mast supporting the booms may be located forward, in which case the wheelhouse is located aft as on a side trawler, or they may be amidships with the wheelhouse forward, as on a stern trawler.
It can be either a side or stern trawler with an insulated hold where the fish are stored "wet," or fresh, after sorting.
A quartet of porpoises began to surf our large stern wake.
Large stern waves can capsize smaller boats and cause turbulence for larger boats.
Modern fishing vessels include fishing trawlers with a small crew, stern trawlers, purse seiners, long-line factory vessels, and large factory ships which are designed to stay at sea for weeks, processing and freezing great quantities of fish.
Another important innovation was the stern chute for stern trawlers, a development made possible by cooperation between naval architects and fishing-gear experts, which permitted large-scale mechanization of gear handling.
Practically all trawlers built today are stern trawlers, with the trawl launched and recovered over the stern.
On smaller stern trawlers the trawl is lifted on board by a hoist.
