HONG KONG HARBOR
Hong Kong Harbor, the portion of Hong Kong that is of primary interest to this evaluation, is centered at approximately 22°18'N 114°08'E (Figure IV-3). The central part of the harbor is located between the north side of Hong Kong Island and Kowloon on the southern end of the Chinese mainland. The busy harbor is large, and it is oriented generally east-west. Approximately eight nmi separates the northern ends of the three main access channels to the harbor, Tathong Channel on the east side of Hong Kong Island, and East/West Lamma Channels on the west side of the island (Figure IV-2). The narrowest part of the harbor exists across the Hung Hom Fairway between Hong Kong Island and the southern tip of Kowloon, a distance of approximately 0.65 nmi (1.15 km).
