Ropes and lines are an important part of any boat, especially sailboats. They have a multitude of uses and there can never be too many of them on board. Take a moment to learn or refresh your memory on the ins and outs of the following knots.
A length of line is of little use unless it is fastened to something, usually at both ends. One or both ends may be belayed (i.e., fastened) to a cleat or a bollard, but often the fastening is made by means of a knot.
