ROV Lightweight Lifting Tether System

A segmented marine tether that keeps a compact diameter for comms/power while adding a load-bearing lifting sleeve for safe launch/recovery, plus torsion control and optional “S-tether” buoyancy behavior. Enables lighter signal tethers to lift heavy ROVs safely: adds a load-bearing sleeve for in-air lift, reduces twist/hockling, and can form an “S” shape to lower tug on the vehicle.
