Let us continue to talk about shipboard lifeboat arrangements. Most passenger ships carry partially enclosed lifeboats and the types of release gear are similar to those used for totally enclosed boats. The winch operator lowers the lifeboat to embarkation deck where it must be securely bowsed. The methods used for that can vary very widely so you should consult SOLAS training manual for detailed instructions. Before anybody enters the lifeboat on an exercise drill, you must confirm that the fall preventing devices are in place and have been checked for security.
Only then can the person in charge enter the boat, turn on the main battery and manually disconnect the external power supply. At this point the lifeboat will be swung into the embarkation position and boarding can begin. The passengers will board the lifeboat through the ports and directed to their seats to ensure an even distribution of weight. The first to board will be placed furthest from the entrance. It is the person in charge's role to take command of the evacuees as good leadership is an important factor in survival situations.
