Location

Matadi (5°49'S., 13°27'E.) lies along the S bank of the Congo River, at the limit of navigation for ocean-going vessels, about 80 miles from the sea. The town is built on the steep and rocky slope of the riverbank and is shut in on all sides by high mountains. It is extremely unhealthy in the hot season, although there are now few cases of malarial fever.

Winds—Weather.—Heavy thunderstorms and torrential rains occur during the wet season. The prevailing winds are from the W.

Tides—Currents.—Matadi has no perceptible tidal rise, but a seasonal difference of 7m occurs between the high river water level andthe low river water level. In the dry season, the current close inshore is weak. However, it runs strongly during the wet season and sometimes vessels experience considerable difficulty when berthing alongside.

The rate of this current varies between 1 knot and 9 knots. At the most downstream part of the quay, the current is particularly strong and sets towards the berths. The current is felt the least at the center berths.

Depths—Limitations.—The port has 1,610m of total main quayage, which provides ten berths. These berths are 143 to 188m long and have depths of 6 to 10m alongside. Vessels up to 24,800 dwt, 179m in length, and 8.2m draft can be accommodated. There are facilities for general cargo, bulk, container, and ro-ro vessels.

The controlling depths in the river vary and vessels should ascertain the latest information from the authorities. Vessels with drafts of 6.4 to 8.2m can transit the river, depending on the season.

Caution.—At the most downstream part of the quay, vessels must use care when dropping the anchor to assist in berthing,
as deep water lies close alongside.
