Stern-to mooring on the Masurian lakes: a step-by-step guide
Stern-to mooring (the so-called Mediterranean mooring, on the Masurian lakes people just say "stern to the pontoon") means backing up to the quay with the stern of the yacht, an anchor dropped from the bow or a bowline on a Y-boom, and two stern lines run onto the pontoon. That's how you moor in tight harbours where berths are scarce and side-by-side you'd fit half as many boats. Sounds scary, but it's a matter of a few tries. Below I break it down piece by piece so a beginner can get the hang of it.
When do you actually moor stern-to
At the height of the season, when harbours are bursting at the seams, the harbourmaster lines the boats up stern-to the pontoon, because that way far more of them fit. Bow-to the pontoon, each boat takes up a wide slice of quay. Stern-to they stand packed tight, one next to another, like cars in a garage. That's why in Gizycko, Mikolajki or Wegorzewo in July and August you'll most often hear from the harbourmaster: "come in stern first." We wrote more about where to even find a berth at peak season in our piece on where to moor at peak season on the Masurian lakes.
Second thing: it's easier to step ashore from the stern. A gangway or one step from the transom onto the pontoon and you're in the harbour. Bow-to, you'd have to clamber over the pulpit.
Bow and anchor, or a Y-boom
There are two variants, depending on the harbour. In modern marinas there are so-called Y-booms or mooring lines on the bottom: lines or floating arms attached to the pontoon that hold the bow. Then the anchor stays in its locker and you just grab the mooring line and make it fast at the bow. Easier.
In older, rougher harbours there are no mooring lines. Then you hold the bow on your own anchor, which you drop on the approach. That's the harder variant, because you have to judge the timing and the length of chain well. We have a separate guide on dropping and holding on an anchor: anchoring a yacht on the Masurian lakes. Read it before you try mooring stern-to without a mooring line.
The approach step by step
First, observation. Before you go in, look at where the wind is coming from and how your neighbours are lying. Pick a gap, decide where the stern should end up. Get the stern lines ready on both corners of the transom, fenders on the sides, the anchor ready to drop (if there's no mooring line). Split the roles among the crew: one at the bow by the anchor, one or two at the stern with the lines.
Then you approach. Line the yacht up bow-away from the pontoon, straight in front of your gap, about two hull-lengths off. Stop, engage reverse and start backing slowly, straight onto the spot. Working astern is the hardest part, because in reverse the stern of the yacht slews to one side (the so-called prop-walk effect), and the rudder barely bites at low speed. So back with a modest but definite speed, so the rudder grips the water.
You drop the anchor from the bow at the moment the bow passes a point roughly one boat-length (or two) off the pontoon. Not too close, because the anchor won't have time to dig in and you'll "ride" on it. Not too far, because you'll run out of chain. Pay the chain out evenly as you back down, checking it lightly so the anchor settles and starts to hold. With a mooring line, instead you catch it with a boathook when the bow comes over the line.
Finally you pass the stern lines. When the transom is a metre or two off the pontoon, the person at the stern passes or throws a line to someone on the pontoon (or steps off themselves, if it's close). Make both stern lines fast on the pontoon cleats, then take up the anchor or mooring line at the bow so the yacht sits stretched between the two: the taut anchor pulls the bow, the taut lines pull the stern, and the boat hangs between them without banging against the pontoon. How to tie off on a cleat without a mistake, we laid out here: what a cleat is and how to moor to it.
| Step | What you do |
|---|---|
| 1. Recon | Check the wind direction, the free gap, how the neighbours are lying. Mark out the spot for the stern. |
| 2. Preparation | Stern lines on the transom corners, fenders on the sides, anchor ready, crew at their stations. |
| 3. Line-up | Bow away from the pontoon, straight in front of the gap, two hull-lengths off the quay. |
| 4. Working astern | Reverse, back slowly but definitely, correct with the rudder and short bursts of throttle. |
| 5. Anchor / mooring line | Drop the anchor from the bow one-to-two lengths off the pontoon and ease the chain, or catch the mooring line with a boathook. |
| 6. Stern lines | Pass two lines onto the pontoon cleats once the transom is a metre or two off the quay. |
| 7. Squaring up | Tension the anchor/mooring line and the stern lines so the yacht hangs between them and doesn't bang about. |
Crosswind and neighbours
A setting wind is the main enemy in this manoeuvre. When it blows from the side, the yacht drifts onto your neighbour before you get a chance to pass the lines. Tip: come in with a slight "wind allowance," meaning aim the stern a bit into the wind, so the drift carries you exactly onto the spot. Back a touch faster then, so the rudder has power and the wind doesn't blow you off in time. If it's blowing hard, don't be shy about adding a few revs for a moment to catch your heading.
Neighbours are the other matter. Have fenders on both sides, not just one. If you see you're drifting onto someone else's boat, better to pull off, do a loop and approach again, than to force your way in and scratch the gelcoat of two boats. Nobody will judge you for a second approach. For a dented pulpit on your neighbour's boat, they will.
Good practice: if there are people in the harbour, ask someone on the pontoon to take a line. The harbourmaster or a neighbour will usually help. It's normal, that's how everyone moors in every Masurian harbour.
The most common beginner mistakes
Dropping the anchor too early or too late. Too close to the pontoon and the anchor won't have time to grab the bottom; too far and you'll run out of chain and end up sitting too far off the quay. Judge it by eye, one-to-two boat lengths.
Working astern too slowly. People are afraid of speed and back so slowly that the rudder does nothing and the yacht does whatever it wants. Paradoxically, a little more speed gives you more control.
No division of roles. When everyone on deck is doing everything and nothing, the manoeuvre falls apart. Sort it out beforehand: who's on the anchor, who's on the lines, who's steering.
Panic in the drift. When the wind pushes the yacht, beginners freeze. Better to pull off and approach a second time than to sit there watching yourself drift onto a neighbour.
Frequently asked questions
Why do you moor stern-to and not bow-to? Because that way far more boats fit on the same stretch of pontoon, and stepping ashore from the stern is easier than a scramble over the bow. At the height of the season harbourmasters line boats up stern-to precisely so the harbour can hold everyone.
When do you drop the anchor when mooring stern-to? During the approach astern, when the bow passes a point roughly one-to-two hull-lengths off the pontoon. Too close and the anchor won't have time to dig in; too far and you'll run out of chain. Then you ease the chain out evenly as you back down.
What do you do when it blows from the side? Aim the stern a bit into the wind, so the drift carries you exactly onto the spot, and back a touch faster so the rudder has power. If you still drift onto a neighbour, pull off and approach again rather than forcing your way in.
Is stern-to mooring hard for a beginner? At first yes, because working astern and the setting wind take a feel for it. But it's a matter of a few tries. Split the roles among the crew, have fenders on both sides and don't be afraid of a second approach. After a few goes it becomes second nature.
