Bowline goes he." An alternative "lightning method" can also be used; see this animation. There is a potential with beginners to tie what is known as an Eskimo bowline. This faulty knot stems from an incorrect first step while tying the rabbit hole. If the loop is made backwards so that the end of the rope (the bitter end) is on the bottom, the resulting knot will be sideways. The final loop of a sideways bowline will slip. This makes it particularly dangerous in the case of an inexperienced sailor, who, in addition to having an insecure knot, is also less
Mutation (knot theory) Mutation (knot theory) In the mathematical field of knot theory, a mutation is an operation on a knot that can produce different knots. Suppose "K" is a knot given in the form of a knot diagram. Consider a disc "D" in the projection plane of the diagram whose boundary circle intersects "K" exactly four times. We may suppose that (after planar isotopy) the disc is geometrically round and the four points of intersection on its boundary with "K" are equally spaced. The part of the knot inside the disc is a tangle. There are two reflections that switch pairs of
