VI. Shipboard Interrogation Techniques
In addition to the interrogation techniques discussed above, having a prisoner on-board a ship poses some challenges given space constraints and that typical interrogation tools are not readily available. Here are a few methods of corporal punishment that have proven useful in the past:
Prow Chaining
The prisoner is chained to the prow with his feet just above the waterline. As the ship is underway, waves will continually crash into the prisoner, both depriving them of sleep and also putting them into a state of continued duress. Prisoners should be positioned such that they are not at significant danger of actually drowning, simply such that they cannot sleep to simulate the effects of sleep deprivation techniques.
Keelhauling
The prisoner is tied to a line, which is then looped underneath the vessel either from Bow to Stern, or Port Side to Starboard Side - depending on how severely the prisoner needs to be punished. The prisoner is then thrown overboard and dragged underwater over the keel as he is pulled to the opposite end. Getting dragged over barnacles and other sea-borne growth attached to the underside of the vessel will cause various lacerations on the prisoner while being dragged, and he should be a bloodied, exhausted mess when he emerges on the other side.
Walking the Plank
An option for Familiar Executions while onboard a ship, the threat of walking the plank in shark infested waters is enough to turn even the most hardened and defiant prisoner. A long plank is extended out the side of the ship, and a prisoner is made to walk down the plank until he simply has to jump into the water. The longer the better so that the subject of the interrogation gets extra time to consider whether to relent and surrender information while his fellow prisoner begs and pleads for salvation. The prisoner who is walking the plank should should have his feet bloodied with fish hooks to ensure that the blood will attract sharks to his location, and that the prisoner is eaten from the feet up to prolong the punishment before he is finally dragged down into the deep.
