Gear Boat Recovery & Flip Lines | Gear Garage Live Show

This podcast is the audio version of the Gear Garage Live Show, where we answer submitted questions and talk all things whitewater.

Episode Summary

In this end-of-year edition, Zach tackles the nitty-gritty of personal rescue equipment (PRE), specifically nerding out on the materials and dimensions of flip lines. The show moves into a masterclass on cataraft frame setup and a high-stakes discussion on the realities of recovering heavy gear boats in swift water—a scenario Zach describes as "a marathon, not a sprint." To wrap things up, Zach clarifies the often-confused vocabulary between Personal Protective Equipment (PPE) and Personal Rescue Equipment (PRE).

Highlights

• The 5mm Flipline Debate: A deep dive into whether ultra-thin Dyneema is practical for flipping rafts. While it saves space, Zach explains why "grabbability" often trumps strength and weight.
• Cataraft Rigging Theory: Zach discusses the "center of mass" vs. "center of pivot" debate when setting up an oar frame and why your seating position should change based on whether you're pushing through big waves or dropping into technical holes.
• The "Bulldozing" Technique: When an 18-foot gear boat flips in 15 mph current, towing with a rope is often a recipe for disaster. Zach breaks down why pushing (bulldozing) the boat is safer and more effective.
• PPE vs. PRE: A vocabulary lesson for guides. PPE is what protects you (helmet, PFD, knife, whistle), while PRE is the gear used to rescue others (throw bags, pin kits, flip lines).

Technical Deep Dive: Flip Lines and Towing

Nerd-Out: Flipline Materials

A viewer asked about making a custom flip line from 5mm braided HMPE (Dyneema). While the material is incredibly strong (often stronger than the carabiners it's attached to), Zach warns that thin diameter rope is punishing on the hands. A flip line's primary job is to be grabbed under duress. Zach’s preference is a slightly wider, low-friction webbing that slides easily over carabiners for mechanical advantage systems but remains easy to grip when you're standing on an overturned floor.

The Reality of Gear Boat Recovery

Recovering a flipped gear boat in continuous, swift water (like the Alsek or certain sections of the Grand Canyon) is one of the most exhausting tasks in rafting. Zach emphasizes:

• Avoid Lines: Tying two boats together in swift current can lead to a tangled, hazardous mess.
• Downstream Safety: If a boat flips, someone needs to "bomb down" immediately to act as a catcher's mitt with a rope from shore.
• Communication: The best recovery happens during the scout. If the recovery looks brutal, talk about the plan before anyone flips.

Gear Mentioned

• River Hardware Flipline: A 14mm ultra-high-molecular-weight polyethylene line designed for low friction and high grabability.
• SOTAR Legend Cataraft: Discussed in the context of frame setup and how to rig for day trips vs. loaded overnights.
