Safety is the number 1 priority on a ship. Everywhere there are signs telling you to mind your head or watch your step. But, the most important safety issue, is the lifeboat/safety drill that everyone has to participate in before the ship sets sail.
Depending on the company (Holland America, Royal Caribbean, Princess, etc.) there are specific standards that HAVE to be met. One of the basic standards is "Everyone has to participate in a safety drill." That's not hard. However, how you participate in that safety drill is different for each line and sometimes for each ship.
As an example, when we were on the Oasis of the Seas, a Royal Caribbean ship, we were instructed to go to the Champagne Bar to see the pre-recorded safety message on the TV that was scheduled to be shown at a specific time. We showed up without our life jackets, listened to the message, watched a live demonstration on how to wear a life jacket, and we were dismissed. That was the full extent of the safety drill.
On most Princess ships, we have been instructed to go to a lounge near our muster station, with our life jacket, and watch a pre-recorded safety message on the TV. Then there's a live demonstration on how to wear a life jacket followed by the passengers actually putting on their life jackets. After getting "inspected" for doing it correctly, everyone is dismissed.
Then there's "The Westerdam" on Holland America. No cushy lounge or bar for the Westerdam...no... We had to go to the actual muster station which is boldly printed on our room key. At the designated time, we proceeded to our muster station where we were checked in. Then came a waiting game as everyone had to be quiet so the captain could speak. He told us what needed to be done in case of an emergency. The captain of this ship is definitely the leader as he has a huge booming voice that does not let anyone even think about doing anything other than following his directions. After the directions, we saw a live demonstration on how to put on the life jacket. We were not requested nor required to put on the life jacket. It did not take long to get to the muster station, but it took a lot of time for everyone to get quiet and then listen to the announcement. It was a very different feeling from any other ship we have been on over the years. I don't know if it was "better" than other safety drills, but it was certainly different.
Whatever the case, when the drill is over, most folks have a general idea what needs to be done in case of an emergency. What is never ever told to the passengers is HOW to get into the lifeboats. Somehow that is completely ignored. I guess we are supposed to know how to do that task.
These are the formal directions for putting on a life jacket.
And these are the formal directions for putting down the extra life rafts. Again, no directions on how to get into the life rafts.
