Ropework & knots

Every line on a yacht has a job, and each job has its rope, its knot and a safe way to handle it. Let a cleat or a winch take the load your hands cannot.

1 · Rope types

Stretch where you moor, none where you trim

What rope should I use for mooring lines, and what for sheets and halyards?

Use nylon for mooring lines and anchor warps: it stretches and absorbs shock loads. Sheets and halyards must not stretch, so they are polyester, or Dyneema for halyards.

RopeBehaviourUse
NylonStretches, absorbs shockAnchor warp, mooring and tow lines
PolyesterLow stretch, hard-wearingSheets, halyards
DyneemaAlmost no stretch, slipperyHalyards; spliced, not knotted
PolypropyleneFloats; sunlight destroys itDinghy painter

A mooring line in a swell takes snatch loads many times the steady pull, so it must stretch; a sheet or a halyard must not. Load a rope to about a fifth of its breaking strength at most: knots, wear and shock use up the rest.

A knot is the weakest point of a line, so a permanent loop is an eye splice. Three-strand rope is the easiest to splice by hand.

2 · Knots

Know each knot by its job

What are the essential sailing knots, and what is each one used for?

Tie a bowline for a fixed loop, a clove hitch for fenders, a round turn and two half hitches to a ring or post, a sheet bend to join two lines, and a figure of eight as a stopper.

BowlineFixed loop for a sheet or a bollard; will not untie under load
Figure of eightStopper in a sheet's end; does not jam
Clove hitchFenders: quick to adjust, can work loose
Round turn and two half hitchesLine to a ring or post; tied and freed under load
Reef knotBinding reef points and sail ties, not joining ropes
Sheet bendJoining two lines; doubled if slippery or unequal
Rolling hitchGripping along a loaded rope or chain
Anchor bendWarp to the anchor ring
Lighterman's hitchHeavy line on a bollard, eased and freed under strain
Trucker's hitchPurchase to tighten a lashing

A reef knot is right over left, then left over right; the same way twice is a granny, which slips or jams. In a sheet bend the thicker line forms the bight. Slip a knot only on a line you are watching.

3 · Cleats and lines ashore

The turn takes the load

How do I tie a line to a cleat properly?

Lead the line to the far horn of the cleat, take a full turn round the base, add figure-of-eight turns and finish with one locking hitch: more only jam.

Lead the line to the far horn of the cleat, take a full turn round the base, add figure-of-eight turns and finish with one locking hitch; more only jam. Keep that turn on to ease a loaded line, and take one on any line too heavy to hold. When two lines share a cleat, the first to leave goes on top.

Making fastturn, figures of eight, one hitch
Slip lineboth ends on board

Ashore, drop the loop over the bollard and adjust the line from the boat. Pass your loop up through another boat's loop first, so that either can leave. A slip line runs round the bollard with both ends aboard: let one go, pull in the other. No knots in it; rig it just before leaving, and have it all aboard before the propeller turns.

4 · Winches and clutches

Friction holds, the tail controls

Which way do the turns go on a winch, and how many do I need?

Turns go on a winch clockwise: two to pull in slack, three or four as the load builds. Tension on the tail makes them grip.

Turns go on a winch clockwise: two to pull in slack, three or four as the load builds. Tension on the tail makes them grip. A self-tailing winch takes the tail over the arm into its jaws last.

  • Ease with the turns on and the tail out of the jaws.
  • Release by lifting all the turns off together, never one by one.
  • Riding turn: take the load on a spare line with a rolling hitch, then clear it.
  • Too heavy: turn the handle the other way for low gear.
  • Handle out when you finish. Hair and scarves clear. Stop an electric winch at any snag.

A clutch holds a line so the winch is free for the next. Check its label before opening it. To ease a loaded halyard, take the load on the winch, then open the clutch; after hoisting, close it before the turns come off. It grips only its own rope diameter. A cam cleat lets go when you pull in a little and lift.

5 · Line handling

Keep yourself out of the line

How do I throw a line so it actually reaches the person catching it?

To throw a line, make the inboard end fast first, then split the coil, half to throw and half to pay out. Aim above and just beyond the catcher; for a long throw, send a light line first.

  • Never stand in a loop of line.
  • Hold a line in your hands, never wrapped round them; wear gloves.
  • Keep hands well back from blocks.
  • If a line runs away, let go, then catch it with a turn on a cleat.
  • No slack line in the water with the engine in gear.
  • Check that a tail is free to run before you release it.

To throw a line, make the inboard end fast first. Split the coil, half to throw and half to pay out, and aim above and just beyond the catcher. If it falls short, pull it in fast, clear of the propeller. For a long throw, send a light line first and haul the heavy one across.

6 · Care and coiling

Chafe, salt, grit and twist

How do I coil a rope on a yacht so it doesn't twist?

Coil three-strand rope clockwise, with the lay, and braid in figure-of-eight loops, which add no twist. Start from the fixed end so that twists run out of the free end.

ChafeFairlead, a sleeve at the quay edge, sheets swapped end for end

Replace a sheet whose cover has worn through to the core. At night, tie halyards off away from the mast.

Practice questions

Questions from this topic, as the app asks them. Open one to see the answer.

Main halyard
  • Luff sags in every gust
  • Old halyard: three-strand nylon

What do you replace it with?

  1. Low-stretch polyester or Dyneema braid
  2. Polypropylene braid, which is light
  3. New nylon three-strand of the same size
  4. A thicker nylon braid for strength
Show the answer

A. Low-stretch polyester or Dyneema braid

Halyards need low stretch to hold luff tension; nylon stretches.

You need to put a loop in the end of a mooring line to drop over a bollard. Which knot?

  1. Clove hitch
  2. Reef knot
  3. Bowline
  4. Figure of eight
Show the answer

C. Bowline

A bowline makes a fixed loop that will not slip and unties after loading.

Knots · Explained in: Knots

This line is being made fast to a cleat. What completes it correctly?

  1. Five round turns and no hitch
  2. A bowline round the cleat
  3. Two half hitches on the horn
  4. A full turn round the base, figure-of-eight turns, one locking hitch
Show the answer

D. A full turn round the base, figure-of-eight turns, one locking hitch

The turn takes the load; the locking hitch holds without jamming.

Deckwork · Explained in: Cleats and lines ashore

You have finished winching in the genoa sheet. What do you do with the winch handle?

  1. Leave it in the winch for the next tack
  2. Take it out and stow it
  3. Hang it over the guardrail
  4. Lay it on the cockpit seat
Show the answer

B. Take it out and stow it

A handle left in fouls the sheets, gets kicked overboard or injures someone.

Winches · Explained in: Winches and clutches

Leaving the quay
  • Stern line paying out across the deck
  • A loop of slack lies round your feet
  • Engine in gear, boat moving off

You are on the foredeck as this line starts to run. Where do you put your feet?

  1. Outside the loop, clear of the line
  2. Inside the loop, to hold it down on deck
  3. On the line, to stop it running out
  4. Anywhere, as the line is still slack
Show the answer

A. Outside the loop, clear of the line

A bight snaps tight the instant the line takes up: never stand in one.

Line handling · Explained in: Line handling

Charter handover, Saturday
  • Mooring lines salty and stiff
  • Fresh-water hose on the pontoon
  • Lines go back into the cockpit locker

What do you do with the mooring lines before you stow them?

  1. Scrub them clean with bleach
  2. Stow them wet, salt and all, to keep them soft
  3. Dry them in the sun without rinsing
  4. Rinse in fresh water, then dry them
Show the answer

D. Rinse in fresh water, then dry them

Salt crystals cut the fibres and stiffen rope; rope stowed wet goes mouldy.
