Alpine coil

Some coils are for rope that is to be stored or hung up out of harm’s way for a period of time;

others are intended to keep a rope handily neat while it is carried, and for imminent use. This
coil is one of the latter.

Coil the rope and, having brought both ends together at the top, bend one back to create a bight
(1). Then take a series of snug wrapping turns with the other end around it (2). Finally, tuck the

working end through what remains of the initial bight, and pull on the other end to trap it securely
(3).
