I made every mistake possible at Porquerolles in July 2021. I came in too fast, my wife dropped the boathook, the lazy line wrapped the prop on the boat next door, and a Frenchman in a Sun Odyssey gave me a look I still think about. By the time we were tied up, half the quay had watched the whole performance.
Stern-to mooring with a lazy line is the standard way you tie up in a Mediterranean marina, and for a sailor raised on floating finger pontoons it feels deeply unnatural the first time. You are reversing a boat that does not want to reverse, towards a stone wall, in front of an audience, holding a slimy rope that has been underwater since the last boat left. It looks impossible. It is not. It is a sequence, and once you do it in the right order it is almost boring.
What a lazy line actually is
In a busy French marina, nobody wants thirty boats dropping thirty anchors that foul each other. So the port lays permanent ground tackle: a heavy ground chain (the chaîne mère) laid along the seabed and held down by concrete sinkers, the corps-morts, with a strong mooring strop running from it up towards each berth. In French ports that strop is the pendille, and you will hear the whole manoeuvre called "prendre la pendille". Attached to its end is a thinner, lighter rope, the lazy line, tied off at the quay edge or to the pontoon. You pick up the lazy line, walk it forward, and haul it in until you reach the heavy strop, which you then make fast at the bow. That strop holds your bow off the wall while your two stern lines hold you to it.
That is the whole system. No anchor needed when a lazy line is provided, and on the French Riviera and in Provence ports they almost always are.
Brief the crew before you enter the harbour
This is the step everyone skips and everyone regrets. The chaos happens because nobody knows their job until the boat is already committed.
Before you pass the breakwater, stop the boat or idle in clear water and assign roles out loud. On my boat it is three jobs:
- The helm reverses and holds the boat straight. Nothing else.
- One crew handles the stern lines, one each side, already led outside everything and back aboard so they can step ashore and return.
- One crew, the moment we are close, lifts the lazy line off the quay, walks it forward outside the guardrails, and hauls it to the bow.
Fenders go out both sides and across the stern beforehand. Lines are flaked and ready. If you sort this on the approach instead of after the agent de port points at your berth, you have already won.
The order of operations that works
The order matters, and the drama comes from getting it wrong. Here is mine, the same order the RYA teaches, refined over too many bad attempts.
- Approach the allocated berth slowly, bow pointing out to sea, stern towards the quay. In a French marina an agent de port, one of the harbour staff, often waits on the quay to show you the berth and take a line; let them.
- Reverse in gently. A 12-metre boat needs almost no throttle. Use bursts, then neutral, and let the boat carry. Steer the stern, not the bow. In a crosswind, you may need to reverse up into the wind first to get steerage way, then come down into the gap with fenders ready on the leeward side.
- Get the windward stern line ashore first. If there is any wind across the berth, the upwind corner is the one that wants to blow away, so secure it before the boat skews. On a single-engine boat, a touch of ahead with the wheel turned to windward then keeps the bow up to wind while the crew works.
- Now the bow. Your crew picks up the lazy line at the quay, walks it forward along the side deck, and pulls. It is heavy and it is filthy; gloves help. Keep hauling until the thin lazy line gives way to the thick mooring strop, and make that strop fast on the bow cleat under tension.
- Take the second stern line ashore and make it fast loosely. In a flat calm you can put both stern lines on before the lazy line, but with any wind across the berth, hold the bow first.
- Adjust everything. Tighten the bow strop to hold off the wall, then balance the two stern lines so the boat sits square and the passerelle reaches.
Snug the bow line hard. A slack bow strop is why boats end up kissing the quay when the wash rolls through.
When there is no lazy line: drop your own anchor
In smaller ports, town quays and many anchorages-turned-moorings, there is no lazy line and you moor on your own anchor. The principle is the same but the bow is held by your ground tackle.
The number that matters: drop the anchor roughly four boat lengths off the quay, with the boat already moving gently astern, paying out chain steadily as you back in. Once you are about one boat length from the wall, snub the chain so the anchor digs in, then bring the stern lines ashore. Too little scope and the anchor never sets; forget to snub it and nothing stops you before the wall. Four lengths out is the figure I keep in my head and it has not let me down.
Wind changes the job. If it is blowing off the quay, it sits on your stern as you reverse and the boat tracks straight, which is the easy case, but the moment you stop it pushes you away from the wall, so get the stern lines ashore quickly and keep them tighter than the bow. If it is blowing you onto the quay, it carries you in on very little throttle, but the wind is not holding anything: the anchor takes the whole load. Make sure it has really dug in before the stern lines go ashore, then keep the chain tight so the stern stays clear of the wall.
A crosswind is the hard one. Drop the anchor slightly upwind of your berth so the chain keeps the bow to windward as you reverse, hang extra fenders on the leeward side in case you are set onto the boat downwind, and get the windward stern line ashore first. That is the day to take your time and accept you might need a second attempt.
The passerelle and stepping ashore
Stern-to means you board over the back of the boat via a passerelle, a gangplank, onto the quay. Rig it once you are tied and balanced, not before. A short fixed plank works for low quays; a proper hydraulic passerelle is a luxury most cruising boats do without. Mind the gap when the wash lifts the stern, and never leave the passerelle weighted hard against the quay when you go ashore, or it will jam and chew the gelcoat as the boat moves.
The three mistakes I still watch people make
Coming in too fast is the big one. The boat that reverses at walking pace looks slow and feels slow and tidies up in two minutes. The boat that comes in hot spends ten minutes recovering and provides the entertainment.
Cleating the stern lines dead tight straight away is the second. Keep them adjustable until the bow is fast and the boat is balanced, then lock everything off.
And the third: trying to do all of it from the cockpit. Med mooring is a deck job. The helm holds the boat; the crew runs the lines and the lazy line. If you are short-handed, take it slower still, and do not be too proud to wave an agent de port over.
Once you have the sequence, the famous French ports stop being intimidating and start being what they are: an efficient way to pack a lot of boats against a wall. If you want to know what the privilege of that stone wall will set you back, what a berth really costs on the Cote d'Azur has the numbers, and if you are heading there in high summer, booking a berth in the Med in August explains how far ahead you need to book.
