I was on a cruise this last May aboard the Royal Princess going to Alaska. It didn’t seem like it had that many lifeboats on that one either.
However, onr of the things I noticed is that it has four very large inflatable life rafts that are on the side of the ship In large room-size boxes.
If I remember correctly, it is international law that you now have to have enough life rafts or life boats for everyone aboard the ship. They did that specifically because of what happened to the Titanic.
Yes...given the size of this beastie...there must be a number of life craft not in sight from the exterior. Inflatable or otherwise.
