Abstract
A plough by means of which a cable may be buried below the sea-bed is characterized by means to vary the length of the path of a cable extending through the plough, which means is responsive to changes in tension in the cable. In one preferred form of the plough, the cable extends over two surfaces and these surfaces are mounted so as to be relatively movable in response to changes in the cable tension.
