A labourer, with his hands covered in sawdust, grinds away a portion of a wooden cargo ship during its overhaul in Karachi's Fish Harbour on Sunday. The process of overhauling a boat takes about a week, in which the boat is brought to dry land and its wooden panels and paint serviced by a team of 20 carpenters and labourers, before it is set back to sea.
