Solution
As with any situational puzzle, there are many correct explanations. So, here is one possible scenario:
A group of people are on the vacation trip in a boat. One morning, they all decide to go deep sea diving, so they put on swimsuits and dive off the side into the water.
Unfortunately, they a ladder on the side of the boat was too short and too far from the water and there was no way for them to climb back in, and they all drown.
