In addition to fire, a boater’s greatest concern may be with the possibility of capsizing or overturning the boat. A number of factors can occur that will result in a boat overturning (high waves, excessive wakes, bad weather) or sinking as a result of damage such as striking an underwater object or another boat.
In the event of such an occurrence, try to turn the engine OFF. Attempt to locate any other people who were on-board and determine whether they are injured. Unless there is fire or release of gasoline, in most instances it is wise to remain with the boat. Except the cases of sinkable damage, it will float. Climbing on the hull will make it easier for rescuers to locate you and others.
