How to Tie the Yosemite Bowline

Usage

The Yosemite Bowline is a modified version of the Bowline designed for added security and ease of untying after heavy loads. It is frequently used in climbing, hoisting, and securing objects, particularly in situations requiring a dependable loop.

Why Learn the Yosemite Bowline?

The Yosemite Bowline improves upon the classic Bowline by adding a Yosemite Finish, which enhances the knot’s security and prevents it from capsizing into a slip knot. This makes it a safer choice for climbing and rescue scenarios where reliability is paramount.

Common Uses

• Climbing:
  • Tying into a harness as an alternative to the Figure Eight Loop.
  • Securing haul bags or heavy loads.
• Hoisting: Creating secure loops for lifting equipment.
• Rescue Operations: Tying secure loops for safety lines.
