After three weeks of repairs, prawn trawler Zephyr is finally back in the water ready to fish. Mark and Adam Robertson put the boat to work to try to pay off the repair bills, but just 30 miles out they suffer an engine problem and have to turn back to shore. After a quick repair they head back out to sea only to be faced with another problem, a broken winch. Through some brute strength they get their gear working again and battle on to get a decent catch.

After receiving word that the current market price on fish is riding high, David cuts his trip short and returns to harbour to cash in, but will he still reach his target? Show less
