The first line to set is the stabilization line. This is critical to success in most pin rescues. The stabilization line basically helps support the trapped boater so they can conserve their strength and breathe freely. In some cases, extra equipment can be quickly sent to a rescuer that is with the victim, sort of like a zip line. When setting a stabilization line, don't forget how powerful a vector pull is - set a low angle V in the line. The deep V also provides more support for the trapped boater. For maximum support where it is needed, the line should cross the paddler right around their nipples and under their arm pits. This set-up makes it much easier for the paddler to support themself in an upright position where they can breath easily without fighting the current. Nearly all pin/entrapment rescues use a stabilization line because it works. If the person is unconscious, this technique isn't as effective. Their arms may flop out of the way causing the rope to ride too high. When the person is unconscious, you really need to get someone to the victim quickly to render assistance.
