I hope I don't get flamed here for my answer but here it is: There seems to be lots of different opinions here. If I were you, I would ask this same question to one of the officers on board your ship, unless, of course, you don't want to hear their answer, and don't want to alert anybody of your intentions. Just sayin'. That would be the smartest and safest thing to do. At worst case, they just might suggest that an adult walk back to the ship with the minor to make sure he makes it there safely. Problem solved!
