Brest, Brittany port and ships, live

The Index rates Rade De Brest a large coastal harbour behind breakwaters. It lists container berths, ramps for roll-on, roll-off ships, dry bulk berths, liquid bulk berths, an oil terminal, general cargo berths, yards for major repairs and a dry dock there. Its entrance channel is at least 12.5 m deep. A vessel traffic service watches the approaches.

Warships often sail with AIS switched off, so most of a navy is missing from the live map. In 24 hours of AIS recorded Oct 12 – 19, the map heard 56 different ships within 10 km of Rade De Brest.

• NGA’s World Port Index rates a harbour by its area, facilities and wharf space when it was last surveyed, not by its traffic, so a busy terminal can be rated small. Where it doesn’t know about a facility it says so, and only what it marks as there is listed here.
• AIS is heard by receivers on shore, so coverage follows where they are: ships far out at sea, or off coasts without one, don’t show. Warships and some others switch it off, and a ship’s type and destination are typed in by its crew.
