Cleat a line with a round turn, figure-eights and a locking hitch: step by step, with the exam context, the safety rule for sheets and the most common mistakes.
The honest answer upfront: you cleat a line with a round turn around the base, two or three figure-eights over the horns and – if the line is to stay put – a locking hitch to finish. It sounds trivial, but it is exam material: in the practical part of the German powerboat licence, "cleating a line with a locking hitch" is on the list of nine possible knots. Seven are chosen, you have to perform and explain six of them adequately, and you get two attempts for each [1].
A cleat is the simplest link between boat and line – and the one most often done wrong.
In this guide you learn the craft and, just as important, when you should not lock a line off at all.
A rule of thumb for line care: laid (twisted) rope can be given a slight twist while coiling, whereas twisting braided rope tends to cause kinks [3].
The line should run onto the cleat in the direction of pull, not chafe sideways over a fitting. Milestone: you see a straight line from the load to the cleat.
Take the line once completely around the base of the cleat, under both horns. This turn takes most of the load and can still be eased under control. That is how you let tension run slowly through your hand instead of the line jerking. Milestone: the line stays on the cleat when you let go briefly.
Lay the line in a figure eight over the horns: once over the cleat, under the opposite horn, back again. Those are the figure-eights. Milestone: the crosses lie flat side by side, no turn overlaps another.
The locking hitch is the finish: you lay a loop over one horn so that it jams under the line. It secures the line when it is to stay for longer, for example a mooring line at the dock. This finish is exactly what the exam asks for [1]. Milestone: you explain to the examiner in two sentences why it holds.
Practise the way back as well: lift the hitch off, undo the crosses, ease the round turn under control. If you only practise making fast, you stand there helpless when it is under load. Milestone: you cleat and release three times in a row in under a minute (practical rule of thumb, not a study).
session one belongs to the round turn alone. Lay it ten times without the crosses and make sure the line does not jam. In session two the figure-eights and the locking hitch are added. In session three you practise with wet hands and gloves, because that is exactly how water, cold and haste come together later. In session four you cleat on a real cleat at the dock while a second person pulls lightly on the line. That way you learn what load feels like before it is really there.
On the water, lines, winches and the boom are the classic injury sources. The RYA risk assessment for sailing schools explicitly names injuries from booms, winches and ropes, as well as slipping on pontoons [4]. For beginners, injuries mostly come from impacts with equipment during manoeuvres [5].
This guide explains and motivates, but it does not replace supervised training with an instructor.
Do the blind test: cleat the line with your eyes closed. If your hands find the round turn, the crosses and the hitch, you can do it in the dark, in the rain or when the boat is pitching. That is not a gimmick, it is exactly the situation in which you will need it later.
You take the line once around the base of the cleat (round turn), lay two to three figure-eights over the horns and, for a permanent belay, finish with a locking hitch. The round turn takes the load, the crosses spread it, the hitch secures it.
Yes, cleating a line with a locking hitch is one of nine possible knots in the practical exam. Seven are chosen, six must be performed and explained adequately. You get two attempts per knot [1].
Preferably not permanently. An RYA safety guideline recommends actively trimming sails instead of cleating them off so they can be released quickly when needed [2]. In gusts, or with little experience, hold the sheet in your hand.
Laid rope can be given a slight twist while coiling without forming kinks; with braided rope, twisting tends to cause kinks [3]. If your line forms loops, first check which construction you are holding.
