40. Eskimo Bowline

Also known as: Boas Bowline

Although similar in its final form to a standard Bowline, this knot is tied
quite differently, so it’s best to approach it as something new. It is trickier
to tie and fair than a standard Bowline, but it is said to be more secure. It is
reliably reported as being of true Inuit (i.e., Eskimo) origin, and was tied in
rawhide as hitches to assemble dogsleds.

Uses: lifting, pulling, safety; may be used as a hitch
Pros: very secure, especially in synthetic line

Cons: tricky to tie and fair
