When a line is finished
Rope rarely parts without warning. The warning is there, you just do not see it unless you know what to feel for. And it parts exactly when the load is highest.
What ages rope
Sun breaks down the fibres, salt crystals work inside like grit, and every edge a line runs over takes more away at that one point than the whole rest of the year.
The hand check
A healthy line is supple and rolls between your fingers. Once it goes hard, stiff or glassy, the material is spent. What counts is not how it feels after the passage but how it feels once dry.
The eye check
Cover fuzzed or split, core showing, bleached patches, local thickening or thinning. A thin spot means the core has already broken inside.
Retire it, do not shorten it
A sheet can be turned end for end once so the chafe point sits somewhere else. After that it goes. A halyard that has run over the same point in the mast for years does not improve by being reversed.
Rope care through the season
Looking after rope comes down to two things: spotting damage early and keeping its causes small. A line that regularly runs through your hands tells you most of what you need to know. Make a habit of running every sheet, halyard and mooring line slowly through your fingers at the start and end of each season, and look at it as you go.
Pay closest attention to the places where a line always sits in the same spot: in the clutch, on the winch drum, around a turning block, at the masthead sheave and where a mooring line crosses the toerail. That is where nearly all the wear happens, while the rest of the line can still look almost new.
Small habits help during the season. Coil lines loosely after sailing rather than tying them up tight. Do not stuff wet rope into a closed locker, and do not leave sheets loaded on the winch overnight. The fibres stay supple and the rope dries out before salt and dirt have a chance to settle in.
Washing ropes: getting the salt and grit out
Salt crystals and fine sand work their way in between the fibres. Every time the line moves they grind away from the inside, and the rope stiffens. Washing is therefore not about looks, it extends the working life. A thorough rinse in fresh water after a salty passage already does a lot of good.
For a proper wash, lukewarm water and a mild detergent are usually all you need. Many manufacturers allow hand washing or a gentle machine cycle with a low spin. Bleach and harsh cleaners attack the fibres and should never go near rope. The care instructions for your particular line are what count.
- Coil the line loosely and tie it off with two or three short ties so it cannot tangle.
- Soak it in fresh water to dissolve the salt.
- Wash by hand or on a gentle cycle inside a laundry bag, using a mild detergent.
- Rinse thoroughly in clean water until no more suds appear.
- Hang it loosely to dry in the shade, never on a radiator and never in strong sunshine.
Rope and UV: the wear you cannot feel
Ultraviolet light breaks down the fibres at the surface. The colour fades and the line loses strength long before it looks any thinner. Lines that live outside all the time suffer most: mooring lines in the marina, reefing lines on the boom and halyards led aft over the coachroof.
On a braided line with a cover and core, the cover protects the load bearing core. A faded, fuzzy cover is therefore a serious warning even when the core still seems fine. Polyester generally copes with sunlight better than nylon, and high modulus fibres usually need a cover to shield them. A berth in a sunny southern cruising ground ages rope noticeably faster than one further north.
Protection is straightforward. Pull halyards up into the mast or cover them, put sheets away in the locker after sailing, and use older lines as mooring warps during long lay ups so the good ones are spared. Check anything that sits in the sun every day more often than lines that spend most of their time below.
Changing a mooring line: when and how
Mooring lines work day and night. Swell and wind keep the boat moving, and each movement rubs the line against the cleat, the fairlead and the pontoon. Replace a mooring line as soon as the hand check or the eye check leaves you in doubt, not once it is visibly chafed through. A hard, glassy line has lost its stretch and no longer cushions the snatch.
When you change it, look at the cause as well. If the old line always chafed on the same edge, fit chafe protection there, for instance a length of hose or a leather or webbing sleeve. The new line should match the length and diameter of the one that has served you well, unless that one was already too short or too thin.
- Prepare the replacement with a spliced or tied eye, cut to the same length as the old line.
- Run out and make fast the new line first, and only then release the old one, so the boat is never left unsecured.
- Fit chafe protection at the toerail, the fairlead and the pontoon.
- Retire the old line from mooring duty for good, at most keep it as a short utility line that never takes a load.
Whipping ends, checking splices and storing rope for winter
An open end frays, and every pass through a block or clutch makes it worse. Synthetic rope ends are usually sealed with a hot knife and then secured with a whipping. A heat sealed end on its own cracks over time, while a whipping keeps cover and core together even after that.
Eyes and splices deserve their own look. A well made splice is generally stronger than a knot, but a poor one can work loose. Check that the cover lies smooth where the splice tapers off and that no core is poking through anywhere.
Over winter, rope should be washed, completely dry and loosely coiled in a dry, dark, ventilated place. Not on the floor of a damp garage and not sealed in a plastic bag, where mildew takes hold. Label each line as you unrig, and it goes back where it belongs in spring without any guesswork.
Frequently asked questions
How often should I wash my ropes?
One thorough wash a season, usually before the boat is laid up, is enough for most lines. After salty passages a fresh water rinse helps as well. More important than frequency is letting the rope dry out completely afterwards.
Can rope go in the washing machine?
Many manufacturers allow it on a gentle cycle with a mild detergent and a low spin. Put the line in a laundry bag or tie it into a loose hank first. The care label of the particular rope is what you should follow.
How do I recognise UV damage on a line?
Faded colour, a rough, furry cover and fine dust that comes off on your fingers when you rub it. If the line feels brittle, the fibres are already weakened.
When does a mooring line need replacing?
When it has gone hard and stiff, the cover is chafed or the core shows through. A line that hardly gives under load should also go, because it passes every snatch straight to the cleat and deck.
Should I grease or oil my ropes?
No. Grease and oil trap dirt and make the line slip in clutches. Some rope makers offer proofing treatments, and the manufacturer will tell you whether one suits your line.
How should I store lines over winter?
Washed, fully dry, loosely coiled and somewhere dry, dark and airy. Airtight packaging encourages mildew and odour.
What this has to do with insurance
Wear and tear is normally not covered under hull insurance, and a consequential loss from a parted line is judged on exactly that. What applies to your contract is set out in your own policy wording. The practical advice stays the same: halyards and sheets have an age, not only a condition.
