35. One-handed Bowline

Also known as: Bowline Loop, Bowline Knot

Climbers occasionally need to tie a Bowline with one hand because the
other is occupied holding on to something for dear life. This method
requires good manual dexterity, but it produces a standard Bowline with all
its virtues.

Uses: general lifting, personal safety, connecting ends of two ropes, sail-to-sheet connections, docklines
Pros: secure; easy to tie, easy to untie

Cons: can capsize and slip; not the most secure form of bowline
