Anchorage.—Due to the great depths and rapid shoaling of

the bottom in the vicinity of Apra Harbor, anchorage outside the harbor is impossible.

Naval Anchorage A, on the S side of Outer Harbor, shows

general depths of 12.8 to 49m over a charted bottom of mud, sand, clay, and coral. Naval Anchorage B, S of Drydock Island, shows depths of 13.4 to 22m, sand and mud bottom.

The explosives anchorage is situated in the W port of the harbor, centered on Buoy 702, and is best seen on the chart. General anchorage is available S of Glass Breakwater, in general depths of 4.5 to 52m, sand, mud, and coral.

Directions.—Vessels from the N should keep 5 miles off-

shore until Orote Point bears 180°, then steer for a position 2 miles W of the harbor entrance. Approaching from the W, Mount Alutom, bearing 097° and in line with Orote Point, leads to a position 2 miles W of the harbor entrance, but is not easily identified. Vessels should enter Apra Outer Harbor with the entrance range ahead bearing 083°, passing midway be- tween Entrance Channel Lighted Buoy 1 and Entrance Channel Lighted Buoy 2. Vessels are cautioned to give the breakwater a wide berth because of the currents and of possible submerged broken-off segments.

10.59

A crosscurrent is often experienced in the entrance. Care

should be taken to keep on the entrance range. A speed of not less than 10 knots is recommended through the entrance to avoid the excessive set by the currents off the entrance.
