Harbour manoeuvres
Harbour manoeuvres decide whether a trip feels relaxed or stressful. With clear roles, slow speed and some knowledge of prop walk, almost any manoeuvre works.
Preparation
- Look at the berth and judge wind and current.
- Hang fenders at the right height and on the right side.
- Prepare mooring lines: made fast on the cleat and led outside the guardrail.
- Assign roles: helm, foredeck, stern lines, one person with a roving fender.
- Have a plan B. Usually that means: abort, motor out, try again.
Prop walk
A propeller does not only push the boat; it also kicks the stern sideways. With a right-handed propeller the stern moves to port when going astern. You notice it most when starting from a standstill.
Tip: before the first harbour manoeuvre, test in open water which way the stern pulls in reverse. Then you can use the effect deliberately when mooring.
Stern-to with a lazy line
In the Mediterranean you usually moor stern-to the quay. A lazy line anchored in the harbour holds the bow.
- Reverse slowly into the gap with fenders on both sides.
- The crew at the stern hands the two stern lines ashore or drops them over the bollard.
- The lazy line is picked up at the quay, walked forward and pulled tight.
- Only then adjust the stern lines so the boat keeps clear of the quay wall.
Alongside and leaving with a spring
Coming alongside is easier when the wind pushes you onto the pontoon. Make the bow spring fast first; then motor gently ahead against it and the stern will swing in by itself.
Leaving works the other way round: motoring against the bow spring swings the stern out, then you reverse away and slip the spring.
