(2) Sunken Rocks near Turnabout Island.
Also, with reference to Notice to Mariners, No. 35, of 27th March 1876, on the existence of a sunken rock, on which the Peninsular and Oriental Company's steam vessel Sunda struck in September 1875, and which was reported as being distant from one mile, to one and a half miles, North of Turnabout island:-
A close examination made by the Nassau of the reported locality, resulted in finding no trace of a rock in the position assigned; the depths everywhere being from 20 to 25 fathoms, mud.
A sunken rock was however found nearer Turnabout island:--this danger (Sunda rock), drying 3 feet at low water spring tides, bears North from the northern extremity of Turnabout island, distant 34 cables, with foul ground inside.
Also, a rock, awash at low water spring tides, was found lying South of the south point of Turnabout island, distant 11⁄2 cables.
NOTE. Vessels navigating in this vicinity should not approach Turnabout island within three quarters of a mile. The lighthouse keepers on Turnabout island report that several steam vessels have been hazarded, by rounding the South point of the island too closely.
