doc, growing up in sheepshead bay we always had at least one boat, my dad being a navy guy began teaching my brother and i about the sea and ships/boats at a very young age, anytime we didnt perform a task to dads liking he would say "your going to be "keelhauled", what that means is that your hands and feet would be tied together with two seperate lengths of rope/line, then youd be taken to the bow, one line would be held by the crew on the port side the other held on the starboard, while under way youd be pushed off the bow while the crew holding the lines taught walked topside down along the length of the boat keeping you centered under the boats keel as you tumbled from stem to stern, ever bump into a "barnacle and have salt water enter the cut, they would do this any number of times depending on the severity of the infraction, if you survived youd be a changed man, perhaps the navy should revisit this form of punishment.
