[66] The plaintiff's evidence was that he worked up to 80 hours per week trawling and maintaining the boat. The plaintiff gave evidence as to the work which he performed on a typical day. Each round trip on the vessel involved between about 13 to 16 hours work. The plaintiff spent one hour preparing the boat, which involved: unpacking the nets; fixing the ropes; checking oil, water, steering and electronics; and shovelling ice into 4 to 6 plastic fish boxes at the co-operative, which he then carried to his truck. The boxes were 2 feet long, 1 foot wide and 1½ feet deep, and were filled ¾ full of ice. The plaintiff then drove to the boat and carried the boxes of ice down the jetty to the boat, which was about 11 metres long. It took the plaintiff 2 hours (each way) to get to the fishing location. On the way out, the trawl booms were lowered. The rest of the 2-hour journey was spent sitting in the wheelhouse motoring. He trawled for about 2 hours and then would winch up the gear, unload the nets and put them back in the water. The plaintiff did 4 to 5 "shots" each night, which took about 2 hours each. While trawling, he sorted the catch, which he then placed in the vessel's cooker and later stored in ice boxes. This process took about 40 minutes. The plaintiff would sit and rest his leg for the remaining time between shots. On his return, he carried the product from the ice box to his vehicle and then to the co-operative. These tasks took 45 minutes to 1 hour. The plaintiff did not use a trolley to assist in unloading the boat. A good catch was about five boxes of prawns. The plaintiff usually loaded the boxes with up to 15 kilos of catch. The plaintiff worked alone, although occasionally a few mates would join him.
