Leonard Brooks' painting of a scene aboard HMCS Cowichan, one the Canadian minesweepers present at D-Day, shows some of the hazards of minesweeping.

In rough seas, an Oropesa float (sometimes called a paravane) has become tangled in a cable (left). Some of Cowichan's crew attempt to free the cumbersome float while it hangs from one of the derricks (centre). The louvered object to the left of the empty cradle for the float (far left) is probably an "otter", one of the devices which kept the minesweeping cable at a certain depth and streaming out behind the minesweeper.
