The first time I moored stern-to in a Provence marina, I had four fenders out and watched in horror as my topsides ground against a rough stone quay that none of them was protecting. The boat next door had a long plank slung across two fenders and sat there serenely while I fended off by hand. That plank is a fender board, and it is the single most useful piece of kit nobody tells you to bring to the Mediterranean. This is what I learned the hard way about fendering for stern-to berthing.
Med mooring puts your fenders in the wrong place
In northern Europe you berth alongside a pontoon and your fenders hang where they always do, between the hull and the dock along the beam. The Mediterranean does it differently. You back the boat in, the stern sits closest to the quay, the bow points out to open water, and the bow is held by the marina's lazy-line system rather than your own anchor.
That changes everything about fendering. The contact point is now the stern quarters and sometimes the transom, not the beam. The thing you are pressing against is often a stone or concrete wall rather than a soft pontoon. And you are jammed between two neighbours close enough to touch, so a fender that slips out of place lets boats kiss in the night. If you have never done it, the mechanics of the manoeuvre are worth reading first in the med mooring with lazy lines walkthrough.
How many fenders, and what size
The rule of thumb is one fender per 3 metres of waterline, with a minimum of three. So a 10 metre boat wants three or four down each side as a baseline, and for stern-to you add a couple at the quarters and transom on top of that. I carry eight on a 38-footer and I use most of them in a tight Med berth.
Size matters more than number. The accepted sizing for a cylindrical fender is one inch of diameter for every four to five feet of boat length, which for a 38-foot boat means a fender around eight to nine inches in diameter. Round ball fenders need roughly twice that diameter for the same boat. Undersized fenders bottom out under load and let the hull touch; the temptation to save money here is a false one.
A practical sizing habit I use: measure your boat's LOA, then add 10 to 20 per cent of buffer for the dynamic loads of swell and wind pushing you about. A harsher mooring justifies upsizing. A Provence quay in a mistral is a harsh mooring.
The fender board changes the game
Here is the kit that turns a rough Med quay from a nightmare into a non-event. A fender board is a plank, traditionally timber, around 1.5 to 2 metres long, that you hang horizontally outside two or three fenders. The board spans the gap and rides against the quay, while the fenders behind it take the load and keep the board off the hull.
Why it works for the Mediterranean specifically:
- It bridges the rough stone and the pilings that point fenders fall between. A round fender will roll off a rough quay edge or drop into the gap between two stones; a board sits flat across the whole face.
- It spreads the load. Instead of all the pressure on one fender, the board distributes it across two or three, so nothing bottoms out.
- It protects the transom corners on the way in, the bit you cannot see and most often clip on a tight stern-to entry.
You can buy a finished board with rubber facing for 60 to 150 euros, or make your own from a length of scaffold plank with a hole drilled at each end for the lanyards. Mine is homemade, cost almost nothing, and has saved my topsides more times than any single fender.
Where to put everything for stern-to
Rigging for a Med berth is different from anything you do up north, so here is the order I work in as we back towards the quay.
- Two large fenders at the stern quarters, hung low, ready to take the first contact as the transom approaches the wall.
- A fender board across those two quarter fenders if the quay is stone or has projecting edges.
- Three or four fenders down each side at the widest part of the beam, because once you are in, your neighbours are inches away and the wind will press you onto whichever side it favours.
- A transom fender or a step-protector if your boarding ladder or swim platform will touch the wall.
Hang them before you commit to the approach, not while you are reversing into a 40-knot gust with an audience on the quay. Fenders sorted in advance are the difference between a tidy berth and a scramble.
Fender socks and the Provence sun
A detail that pays off in the south: fender socks. They are fleece covers that slip over the fender, and they do two jobs. They stop the fender squeaking and chafing your gelcoat, and they stop the black scuff marks that a bare fender leaves on a white hull after a season of stone quays. They also shield the PVC from the Mediterranean sun, which degrades bare fenders fast in Provence. A set is 40 to 80 euros and worth it for the topsides alone.
Inflatable, foam, or the flat marina fender
Not all fenders are equal, and the Mediterranean rewards thinking about the type as well as the size.
The standard inflatable cylindrical fender is the all-rounder and what most boats carry. It is light, cheap and adjustable: let a little air out for a soft contact, pump it hard for a heavy load. The weakness is that it can roll off a rough quay edge, which is exactly why the fender board matters in Provence.
Solid foam fenders never deflate and never burst, which is reassuring, but they are heavier and bulkier to stow and cannot be softened or firmed up. They suit a boat that bashes against the same quay all season more than a cruiser hopping between berths.
Flat or cushion fenders, the rectangular kind, are the secret weapon for stern-to. Hung at the quarters they sit flat against a stone wall without rolling, and they cover more area than a cylinder for the same stowed bulk. A pair of these at the transom corners, behind the fender board, is the most comfortable stern-to setup I have found.
Whatever the type, check the valves and the seams at the start of the season. A fender that deflates overnight in a tight August berth is the one that lets your topsides kiss the neighbour's, and the cost of replacing it is nothing against the cost of a gelcoat repair.
What I carry for a Provence season
For stern-to mooring up and down the Var and the calanques, my fender kit is:
- Eight cylindrical fenders sized at eight to nine inches diameter, with socks on the lot.
- One homemade fender board, two metres of scaffold plank with rubber facing and rope lanyards.
- Two spare fenders kept deflated for the days a neighbour rafts alongside or a quay is rougher than expected.
The fendering is only half of a tidy Med berth, of course. The other half is the gangway you put ashore over the gap between your transom and the quay, and I have covered that separately in the passerelle and gangplank guide for stern-to berthing. Get the fenders and the board right and the boat rides quietly all night; get the passerelle right and you walk ashore for dinner without getting your feet wet. Both are worth the locker space the moment you point the bow towards Provence.
