All entertainers are required to participate in passenger and crew boat drills. Drills will teach you how to act if an emergency situation arises. Boat drills happen once per cruise and are compulsory for both crew and passengers. A drill lasts about 20 minutes and is similar to an airplane drill. There are also special training periods for crew, which you must attend. Although cruise ships are extremely safe, take the time to learn how to save your life and that of others in case of emergency. These drills are part of life at sea and are not considered part of your work schedule.
