04 KNOTS
While many elaborate and complicated knots exist, a good knowledge of a number of
simple knots is all that is required for most situations. What is needed are techniques for
joining lines even if they are of different diameters, for securing a bight or loop on a line,
and ways of securing lines to poles, bollards trees etc. The following is probably sufficient.
Refer to diagrams
For joining lines:
Reef knot:
Useful for narrow cordage. Not good on larger lines. Easily miss-tied into a Granny knot.
Sheet Bend:
Good for lines of equal or unequal size. Ties securely
Fisherman’s knot:
Very easy and secure way to join lines of same or different size but hard to undo if it has
been under load.
To make and secure a loop:
Bowline:
Reliable, quick to tie, never slips, can be tied with loose line or line under tension, easy to
undo after load. An indispensable knot and by far the best way to create a loop on a line.
Securing line to post etc:
Clove Hitch:
Easy to tie but can jam if it has been loaded heavily, Can slip along the pole or post and
can work loose if intermittently loaded. With an extra locking turn it becomes a Rolling
Hitch which is more secure.
Round Turn and Two Half Hitches:
Easy to tie, secure once loaded, but remains easy to undo.
Anchor Hitch:
Similar to above but even less likely to loosen. It is however harder to undo after loading.
