The Mighty Vector Pull



The Mighty Vector Pull
The Vector Pull is an additional mechanical advantage you could add to an existing line for many applications.  The vector pull can be created by a hand over hand motion on the haul line, a carabiner attached to an additional throw line, or long piece of webbing which, will then be attached to the haul line of the swimmer or rescuer [reference picture above].     
Why use the Vector Pull?  
·         Increases your pulling power
·         Can reduce the distance downstream of bringing someone to shore

Where would I use the Vector Pull?
·         To assist in retrieving a swimmer holding a throw line
·         To assist in retrieving a tethered rescue swimmer and victim after the rescuer has made contact  
·         During a pendulum with a person(s) or boat
·         Unpinning a boat off an obstruction

What is the set up? Here are a couple of examples. 

Throw Bag assist
·         Personnel - 2 to 3 team members…possibly set up as downstream safety.
o   Rescuer A – Thrower/Belayer, Rescuer B – Anchor or additional thrower, and Rescue C – Vector Man
·         Once victim receives throw line from Rescue A, Rescuer C clips in vector line close to Rescuer A, starts walking downstream while panning out rope. 
·         The objective is to get the vector line closer to the swimmer to reduce pull on Rescuer A.
·         Once vector line is closer to the swimmer it can be tensioned while still moving downstream which will bring the swimmer to shore.
·         The speed of the vector pull needs to be at a higher pace walk…don’t run! 
Tethered Rescue assist
·         Personnel – 2 to 3 team members…set up as downstream safety.
o   Rescuer A – Tethered Rescue Swimmer, Rescuer B – Belayer, and Rescuer C – Vector Man 
·         Once the victim is contacted by Rescue A, Rescue C can clip-in and start walking downstream while panning out rope.
·         The objective is to get the vector line closer to the swimmer to reduce pull on Rescuer A.
·         Once vector line is closer to the swimmer the vector line can be tensioned while still moving downstream which will bring the rescuer and swimmer to shore.
·         The speed of the vector pull needs to be at a higher pace walk…don’t run!    
 
Are there limitations to the use of the Vector Pull? 
·         Yes, you will need room on shore to move down stream.

Okay, now it is time to go practice the Vector Pull.  Here are a few reminders!
·         DO NOT clip the vector pull to the haul line until the swimmer is holding the line or rescuer has made contact with the victim.
·         If you are the Vector Man make sure to have the gate of your carabiner already open for an easy connection and you are standing on the downstream side of the thrower/belayer.
