Mending fishing nets is no easy task when the net is from a purse-seiner and may be up to 3,000 metres long and 300–400 metres deep, and weigh 6 tonnes, as in the case of super-seiners.

The design and construction of these nets are complex, as they have to function well in a variety of situations, weather and sea conditions that are pretty challenging. Not only do they have to withstand the complicated mix of forces and tensions during setting and hauling, they also have to cope with the extra stress put on them by being used under potentially different currents from the water surface to the bottom of the net.

Running repairs are done constantly. Many are done on board, but major repairs require a large, flat surface such as a wharf or net yard, and the use of forklifts and other equipment to move the net panels around. Francisco Blaha gives us a better appreciation of the difficulty crews face when repairing nets, at sea and in port.
