The tidal currents off Sawai Bay set NE on the flood tide.An observation spot lies on a small promontory that extends WNW from the coast about 1 mile S of Keating Point. Keating Point Light is shown from a round metal tower on the point; a racon and a radio beacon transmit from the tower.
A coral patch, with a least depth of 10.1m, was reported to lie about 0.7 mile NW of the observation spot. A 9.1m patch lies 0.8 mile WNW of the same spot.
Anchorage can be taken, in a depth of 21.9m, rock and coral over a thin layer of sand, about 0.8 mile N of Sawi Village.
Anchorage can also be taken in similar depths just over 1 mile W of the observation spot.
