68. Rolling Hitch
Also known as: Magnus Hitch, Magner’s Hitch
Where the Clove Hitch only works well when the load is at nearly a right
angle to the object, this cousin knot holds securely when the load and the
object are in or near alignment with each other. It therefore works well to
hoist spars, pilings, and other poles in a vertical orientation.
Uses: lifting or securing a load in the same direction as a shaft or line, taking strain off another rope,
pulling or securing another rope
Pros: secure and easy
Cons: only secure with load in line with object
