TARAPUR POINT TO SUVALI BANK General information Chart 254,210,209,207 Route 1 The route leads 92 miles N from a position W of Tarapur Point (19º 50'.75N, 72º 39'.46E) to a position NW of Suvali Bank. Topography 1 Southern part of this stretch of coast is generally low, sandy and fringed with bushes, it is indented by shallow bays and creeks; inland, there are several prominent peaks. 2 The coast, North of Nani Daman (20º 24'.86N, 72º 50'.22E) is watered by springs and thickly covered by vegetation or date palms in several places. The tide runs up through the river mouths or creeks and behind small hillocks of drifted sand where it floods extensive salt marshes. 3 There is an alluvial belt, towards the N end of this coastline, through which the Tapi (Tapti) River forms a deep and fertile delta. 4 On this stretch of coastline; the rivers, shallow bays and creeks are mostly fronted by an extensive coastal bank making them accessible only at high water and with local knowledge. 5 The coastal bank fringes the shore between Suvali Point (21º 05'.0 N, 72º 38'.0 E) and the entrance to Tena Creek, 8 miles NNW; W of Suvali Point it dries and extends about 1 mile offshore. Suvali Hills, a group of sandhills, stand on the coast about 5 miles N of Suvali Point. Off-lying shoals 1 Malacca Banks consist of four long narrow banks, lying between the parallels 20º 20'.0 N and 21º 20'.0 N, which obstruct the entrance to the Gulf of Khambhat their names, from E to W, are Eastern Bank, Breaker Bank, Narmada Bank and Western Bank; the positions and extent of these banks are shown on the chart. 2 Eastern Bank has very deep water close to shoal patches, some of which dry, and over which the sea breaks in its N part. 3 Breaker Bank has extensive shoal patches, lying in a N/S direction on its N part, over which the sea breaks; the sandbank near its centre (20º 45'.0 N, 72º 24'.0 E) is visible at a good distance with the sun on it. A dangerous wreck lies, in the vicinity of 20º 24'.58N, 72º 05'.97E, near the S end of this bank. 4 Narmada Bank has an extensive patch of drying sand near its center and a small patch near its N end. 5 Western Bank dries in places. A stranded wreck lies at its N end in approximate position 21º 06'.6N, 72º 09'.15E. Development area 1 An oil and gas development area has been established, with several works in progress, in the approaches to the Gulf of Khambhat (S of Western Bank) in an area bounded by: 20º 20'.0 N 71º 53'.00 E 20º 20'.0 N 71º 48'.95 E 20º 50'.0 N 71º 48'.95 E 20º 50'.0 N 72º 08'.00 E 20º 35'.0 N 72º 08'.00 E 2 Anchorage and trawling are prohibited within this area due to the presence of oil and gas pipe lines and submarine power cable. Depths 1 To seaward of the 10 m depth contours lying off the Konkan coast and Eastern Bank, S of latitude 21º00'.0 N,there are a number of dangerous wrecks, the positions of these dangers are shown on the chart. Principal marks 1 Landmarks. The following marks are positioned from the watch tower that is described below: Watch tower (21º 08'.865N, 72º 44'.16E). Building, water tower and chimneys (5½ miles WSW). Chimney (19º 58'.01 N, 72º 42'.98 E), red obstruction lights are exhibited (275 m in height). Chimney (2 miles WNW). Towers (3 miles WNW). Towers (2¼ miles NW). Flare situated (5 cables NNE). 2 Major lights. Tarapur Point Light (19º 50'.74N, 72º 39'.46E). Umargam Light (white concrete tower, red bands, 30 m in height) (20º 11'.8N, 72º44'.94E) stands close SSW of a ruined tower situated on the S side of the entrance to Varoli River. Storm signals are displayed in the vicinity of the light, the brief system is used. Valsad Khadi Light (white tower, red bands, 45m in height) (20º37´.78N, 72°53´.22E). Machhiwada Light (white round concrete tower, black bands, 30 m in height) (20º 48'.76N, 72º 49'.70E) stands 6 cables NW of the N entrance point of Kanai Creek.

Hazira Light (white round masonry tower, 25 m in height) (21º 05'.53N, 72º 38'.56E) stands 6 cables NE of Suvli Point. Vaux's Tomb, which of a former Deputy Governor of Mumbai accidentally drowned in Tapi River, stands close SE of the lighthouse. Directions Cautions 1 Extensive reefs and foul ground extend up to 4 miles offshore between Vadhavan Point (19º56'.0 N, 72º 39'.85 E) and a position close S of Nani Daman, 30 miles NNE; vessels should not approach this coast in depths of less than 20 m. 2 Malacca Banks Channels. It is not advisable to use these channels which, although deep, are generally narrow and intricate towards their N ends; also, the channels are unmarked and too distant for fixing from objects on the coast at their S ends. 3 Malacca Banks are steep-to in places and, as soundings may not give sufficient warning, should not be approached on a falling tide. The N limit of the banks has not been closely examined.Local knowledge is must to use the Sutherland channel. Coastal route 1 The route leads 75 miles N from a position well W of the reef surrounding Tarapur Point (19º 50'.75 N,72º 39'.46 E), and clear of a dangerous wrecklying 7½ miles W, to a position W of Suvali Point, passing (with positions from Udwada (20º 29'.0 N, 72º 52'.5 E): 2 W of Vadhavan Point (35 miles SSW), a low point covered with mangrove bushes, which is surrounded by foul ground extending nearly 3 miles from it. Then to: 3 W of Gulur Point (27 miles SSW), a low point covered with coconut palms. Then to clear of an ODAS light-buoy (special) (31 miles SW) moored in position 20º 07'.0 N, 72º 30'.0 E, a 500 m berth is requested. Then to: 4 E of Eastern Bank (26 miles WNW), which is steep-to and soundings give very little warning of approach to the danger. And depending on draught clear of the narrow bank orientated NNE/SSW (16 miles WNW), and: 5 W of the shoal water and rocky patches in the shallow bight extending about 33 miles NNW of Udwada, then toW of a dangerous wreck (35 miles NNW) with another dangerous wreck lying 2 miles NE of it, andto Sutherland Channel. Sutherland Channel 1 Sutherland Channel leads E of Eastern Bank 5 miles N from a position W of Suvali Point (21º 05'.0 N, 72º 38'.0E), to a position SW of Suvali Bank passing W of Hazira Offshore terminal. Suvali Bank (21º 12'.0 N, 72º 36'.0 E) which dries, is sandy at its edge with mud near the high water mark, it is just detached from the coastal bank E. 2 In the vicinity of position 21º 21'.0 N, 72º 22'.0 E, the route then leads NW towards the center of the Gulf of Khambhat, passing NE to the N end of Eastern Bank where it dries and keeping well clear to the SW of Gulwala Bank (21º 18'.0N, 72º 29'.0E), which dries near its center, and NE of the N end of Malacca Banks (21º 18'.0N, 72º 23'.0E). Local knowledge is essential, for the vessels, to use this route. Useful marks 1 Mahalakshmi (19º 55'.87N, 72º 55'.01E) a mountain, with a pointed summit, which slopes gradually N and S from its center. 2 High Land of Saint John (Sunjan) (20º 03'.89N, 72º 49'.68E), a round-shaped mountain. 3 Maroli Light (white metal framework tower, 11 m in height) (20º 17'.89N, 72º 46'.64E) is exhibitedfrom 16th September to 15th June.
