Oropesa Minesweeping Float
Oropesa floats (sometimes called paravanes) were essential minesweeping equipment.
Minesweepers used Oropesa floats to support one end of a cable fitted with specialized devices, including cutters that severed the lines attaching underwater mines to the seabed. The cable, attached to a U-shaped towing bracket (bottom) could be more than a kilometre long. A flag attached to a small pole (top) indicated the float's position at the end of the cable and one edge of the area cleared of mines. When not in use, the large floats, over three metres long, were prominent objects on a minesweeper's deck.
