Перевод на русский
To call for a pilot, the ship either sends a radiogram beforehand or hoists the signal when she approaches the pilot station or, which is common nowadays, the Master contacts the pilot station by radiotelephone. A pilot may board the ship either near the pilot station or in the offing.
When the pilot launch is nearing the ship the pilot is asked which side he wants the ladder be lowered on. If the wind is fresh or strong, the pilot usually taken aboard from the lee side.
To hold the launch against the sea, a boat rope is put over and the fenders are shipped on the side where the launch makes fast.
Most of the pilot boats are now equipped with a continuous rubber fender which runs along the boat’s sides, bow and stern and is about 50-60 cm wide. This makes shipping the ship’s fenders unnecessary. In some places where the traffic is rather dense, the Pilot Station asks the master to embark and disembark the pilot while the ship is under way (usually at a speed of not more than 16 knots).
In compliance with the International Convention for the Safety of Life at Sea, 1979, the ships shall be provided with the International Standard Pilot Ladders and Mechanical Hoists.
Usually the watch officer meets the pilot and shows him to the bridge. Then the pilot manoeuvres the ship into the harbour to her berthing place. Sometimes the pilot takes the ship only into the harbour and the port pilot boards the ship to manoeuvre her to the berth. He also sees to the mooring of the vessel.
Although the pilot is consulted as to what course should be steered and practically it is he who cons the ship to her place, yet the responsibility for the safety of the vessel lies with the captain
