Do You Draw Straws? Which Crew Must be in the Lifeboat

On a cargo vessel, there are twice as many lifeboat seats as the maximum crew and passenger capacity. If the lifeboats on one side of a ship are unusable due to damage or excessive angle of incline, there will be enough seats on the usable side. When I was on a ship with one temporarily- disabled lifeboat, part of crew travelled to the next port by airplane, so that this safety law would not be broken. The station bill lists lifeboat assignments and duties for crew and passengers. For simplicity, crewmembers assigned to the working lifeboats would continue to exercise those roles, such as launching or steering away from the ship. If it turns out that only one lifeboat out of four is launchable, and there are not enough seats, there are inflatable survival rafts located adjacent to the lifeboats on either side of the ship. Much better than their World War Two era predecessor that resembled a giant floating donut, these modern models offer the opportunity to stay fairly dry while under a canopy. Here’s an exercise for ethics and ship’s management: who should get the better chance for survival in the lifeboat, and who should be sent to the raft? The lifeboat needs two engineers in case engine or electrical adjustments are required. The shock of a maritime casualty has incapacitated many would-be survivors, so all survival tasks must have two people assigned, to ensure that the job gets done. Lifeboatmen, or “Persons Proficient in Survival Craft”, are officers and able seafarers who are trained in navigating and managing day-to-day life in a lifeboat. Part of this qualification used to require demonstrating competency as a coxswain while rowing a boat with your classmates or shipmates. You can never have too many lifeboatmen on your lifeboat, although each raft should have at least two qualified personnel. Contrary to popular belief, the captain should avoid going down with the ship. The captain is an established authority figure to the crew, but more importantly, someone with celestial navigation skills. (For about 20 years, the US Navy dropped this competency, relying instead on GPS navigation on the ship, or a quick rescue by a coalition vessel if the ship must be abandoned. This competency has been restored.) Always bring a successor as well- the second mate is often the most proficient at navigation, as part of their daily shipboard duties of charting course. A modern enclosed lifeboat, an orange jellybean of sorts, is self-righting, provided that occupants remain seated, and that the lifeboat is not overweight. They also have engines, while rafts require rowing or towing. Inflatable rafts lack this self-righting feature, so anyone who can’t pull the weight of the raft, or the oars should be in the lifeboat. Think exit row on an airplane- children, the ill, and the very elderly. The lifeboat will be much drier than a raft. The chief steward or cook is often delegated the responsibility of managing food and water rations. While a survival amount is pre-staged inside the lifeboat, bottled water and non-perishable carbs and protein will be brought onboard if time permits. The medical officer, if there is one, may bring a go-bag onto the lifeboat. Anyone with metal implants or artificial limbs must ride in the lifeboat, due to the risk of puncturing the raft with sharp objects. Anyone who is not in a survival suit- an orange or red wetsuit issued to all crew- should be in the lifeboat. Negligence should not be assumed- survival suits are mostly kept in staterooms, not workplaces, and crewmembers are discouraged from returning to their rooms for missing items. Most importantly, fill the darn seats. On the RMS Titanic, an Edwardian sense of propriety sent lifeboats away with empty seats. I did this tabletop exercise as Leadership and Teamwork Training as a Third Engineer, but didn’t realize it until now. The scenario was choosing eight people to travel from a disintegrating moon colony in an escape pod. They had to keep it abstract.
