I actually have a friend who did this: How many of us think it is right for a captain to take his parents on a ten day cruise, without the owner's knowledge? Specifically, the vessel is being transported to the Carribean to hopefully pick up some charter business, and the captain allows his parents to come along, sleep in one of the several vip cabins, and even stay on board for several more days once the destination is reached. Sounds like theft to me--am I wrong? The particular owner stated quite clearly upon retaining the captain that no unauthorized persons would be allowed aboard, and such was even included in the employment contract. I would love to hear everyone's thoughts about this situation, and how the owners you know would deal with it.
