Knots

The reef knot is used to tie two ropes together of equal diameter, it is, however, quite an un-secure knot.

It is especially good for tying two lines of different diameter, and is much more secure than a reef knot.

The Bowline is also known as the King of Knots as it is one of the most important maritime knots.

This knot is used to join to two pieces of rope of different diameters, it is more secure than the sheet bend.

A Round Turn and Two Half Hitches is used to tie a line to a ring, very good if the line is under tension either when tying or undoing the knot.

The Rolling Hitch is used in sailing to relieve the tension on a line or chain. You can slide it in one direction but not in the other.

The clove hitch is used most commonly to tie your fenders onto your boat. It is easy adjustable, since feeding in rope from either direction will loosen the knot to be tightened at a new position. 

The figure 8 knot is sometimes called the Flemish knot. It is used as a stopper knot and is quick and easy to tie.
