Thethered Rescue (Live Bait)
Sunday, May 18, 2025 at 12:24PM Tethered Swimmer Rescues are one of our "7 Cores Skills". The integration of of a QRHS into our PFD's is probably the biggest game changer in advanced rescue over the past 20 yrs.
Quick Release Harness System
There are various professional opinions on the threading of your Quick Release Harness (QRH)
Rescuers need to "Try and Test" for themselves what threading is most appropriate for them
Note: Threading contrary to manufacture's suggestion could lead to liability issues
1. Full tri-glide threading (tested load bearing/maximum friction)
2. 1/2 tri-glide threading (mostly untested load bearing/moderate friction)
3. Direct threading (mostly untested land bearing/minimal friction)
Direct threading is most often used when towing where easy escaability is necessary

Rescue Tethers
Rescue tethers are a way for rescuers to engage their rescue harness without having to "reach and clip" behind their back
Safety Considerations
1. Ensure Rescue Tether is "parked" on a quick release tab on your PFD.
2. Do not 'hard clip" your Rescue Tether to your PFD
3. Replace the original carabiner with a locking carabiner
Practice clipping, unclipping and blowing your harness
Tethered Rescue Sequence (Live Bait Sequence)
1. Tethered Swimmer enters with SWE (when deemed secure)
2. Tether Swimmer enters when Subject is in the "slice of pie" (45-90 degrees upstream from rescuer)
3. Tethered Swimmer raises their hand once they have contact with Subject
4. Tethered Swimmer rotates torso upstream and "windmills" in river arm to grab the rope thus adjusting the angle of force of the current on tethered swimmer’s body
Anchor/Belay Rescue Sequence
1. Anchor/Belay positions themselves downstream of the tethered swimmer the same approximate distance as the subject is from shore. This allows the Tethered Swimmer some time to swim to the subject without the line belaying them back to shore.
2. Anchor/Belay takes in rope as soon as Tethered Swimmer has made contact with the Subject (reducing the Pendulum Arc)
3. Anchor/Belay prepares for load on the line by choosing appropriate anchor/belay position
"V" Lower
1. The Tethered Swimmer is anchored on both sides creating a movable platform out of the rescuer (can be hard to maintain in heavy current for sustained periods)
2. Best to maneuver Rescuer using "pendulum" forces rather than trying to fight the current
3. Anchor/Belay is best with multiple people (upstream personnel in Hip Belay position)
4. Anchor/Belay is better to walk upstream and downstream rather than pulling thus maintaining consistent angle between anchor/rescuer/anchor
Advanced Techniques
Hydraulic Rescue
1. Tethered Swimmer positions themselves in proximity to the boil line
2. Tethered Swimmer leaps for Subject (kayak/canoe/raft) when it reaches its furthest downstream position and is slowed down to a near stop
3. Tethered Swimmer grabs craft at this point BEFORE it is recycled back to the seam of the hydraulic (starts to cartwheel)
4. Tethered Swimmer may use an "extension" to clip the craft to remain hands free in the "pull" phase of the rescue (grip strength is weakest point in the system, extension may be rescue tether or end of rope where Tethered Swimmer is connected midline with a Directional 8 or Butterfly)
5. Rescue ends when all Subjects are out of hydraulic (be wary of multiple swimmers in rafting situations)
6. Anchor/Belay must be thoughtful about positioning
7. Anchor/Belay must be nimble and dynamic to move to appropriate position during "pull" and "post pull" phases of the rescue
Teaching Tips
Thoroughly explain that this is a high risk form of rescue which also has high reward. Students MUST experience blowing their harness on dry land to ensure they have some muscle memories to do that in the water.
