Most definitely an apology - an unbelievable situation - an investigation should point to what caused the accident - it usually comes down to human error - someone not locking something or making sure it was secured - something like this will make me look twice as I board a ship again.
For some reason, when I have had to "walk up the gang plank" I have always been leery of the last step and always look to see if it is totally across to ship.
