My experience was on large highly mechanised trawlers in the North Sea - sleeping for two or three hours then gutting fish for a few hours then eat and sleep and repeat for best part of 5 days.... NB The "highly mechanised" part just adds to the fear factor - winches and other heavy equipment are scary enough at the best of times, but when the sea is rough, its dark they are (for me) terrifying.
