QUESTIONKevin operates fishing tours off the Slippery Coast in South East Queensland. Kevin has a small boat. The marine authority, which regulates licensing for tourist operators, has determined that Kevin’s boat can safely accommodate two passengers at a time.Simon has invited his brothers, Paul and Mark, to come from Victoria to the Slippery Coast for a holiday. Simon arranges to take a fishing trip with his brothers on Kevin’s boat the morning after they arrive.Kevin was unwell that morning and told his son, Jack, to take the boat out. Jack is 16 years of age and does not have a boating licence. Jack decides that it will be all right to take three people out because the regulations are very conservative. Jack knows that other operators frequently exceed their limit. He makes sure he has three lifejackets on board for his passengers.The brothers arrive early at the dock to board the boat. Jack notices that the three brothers are all very large men. On boarding Paul notices a sign attached to the boat, which says ‘Lifejackets must be worn at all times.’ Paul thinks that a jacket would be hot and uncomfortable and ignores the sign. The weather looks fine. They head out to sea.
