	General Information
	11.110
1	Grand Riviere Noire Bay (20º21'.82S, 57º21'.26E) is an opening in the coastal reef which lies between the mountain spurs mentioned at 11.104.
	The bay may afford a fairly good anchorage but, during W winds, a very high swell sets in which is least felt towards the N side. Vessels should be prepared to depart at short notice.

	11.111
1	From a position WNW of L’Harmonie (20°22´.30S 57°21´.64E) the track leads E for about 29 miles passing:
	N of a 9.1 m patch (20°22´.18S 57°20´.79E) thence:
	N of L’Harmonie, a township standing on the S side of the bay, thence:
	Between the drying reefs extending 5 to 6 cables from either side of the bay. The reefs dry and are easily seen, while the sea breaks heavily over Hermione Spit (20°22´.16S 57°21´.26E) which forms the outer end of the reef 
	extending from L’Harmonie.
2	A shallow bar, subject to constant change during freshets in the rainy season from January to March, lies in the mouth of Grande Riviere Noire (20°22´.00S 57°22´.50E) which flows into the head of the bay.

	Useful marks :
	Martello tower  (20°21'.28S 57°21'.73E).
	Tamarin Mountain (20°20´.88S 57°22´.58E).
	The bay is easily identified by these marks. A second Martello tower, close SE of L’Harmonie, cannot be seen from seaward.
3	Anchorage may be obtained in 10 to 27 m, sand, mud and coral.
	Landing is possibleby boat at a pier in front of the village of Riviere Noire (20°22´.12S 57°22´.66E), at the head of the bay.
