The capstan knot
It is an essential knot on board. It is used for several purposes, but in our case, we use it mainly to attach the fenders to the sides of the boat. Very practical because you can easily adjust the height of the fenders without undoing the knot, just by loosening it. It is possible to secure a capstan with two half hitches, especially if the rope is of large diameter.
This knot is widely used on a boat but also in the mountains. It is simple to make, very solid while remaining easy to undo once the tension is released. Be careful, on a rope that is not under tension, it can become undone by itself. Especially if the rope is thick. In principle, it will not be used on an anchor or to moor a boat. The surf could cause it to unravel on its own or to slide.
The cleat knot
This is the third knot that you have to know how to make perfectly. It is made around a cleat that is found on boats, but also on docks. It is mainly used to “tie up” the boat when it is docked. It is also used quite simply when you want to tie down a rope. It is important to make it correctly in order to ensure its strength but also its simplicity to be undone it quickly, even under tension.
The figure eight knot
It takes its name from its shape. Certainly one of the easiest knots to make.
This is a stopper knot. This knot is made at the end of a line to prevent it from going through a block, a cleat or a spinlock. It is relatively easy to undo, does not damage the line too much, and forms a larger knot than the simple knot. Be careful, on the sheets and spinnaker arms, you should never tie a stopper knot.
Doubled up, it is also widely used in the mountains by alpinists to rope up.
