The northwestern boundary of the zone is the straight line that is an extension seaward of the Kaneohe ship channel range with an azimuth measured clockwise from True South of 227 degrees to the limit of the territorial sea. The southeastern boundary of this zone is the straight line that is an extension seaward of the Kaneohe Sampan channel range with an azimuth measured clockwise from True South of 217 degree to the limit of the territorial sea. As an aid in locating the southwestern boundary, it exists between the Kaneohe Sampan channel and Kaneohe Ship channel ranges along a straight line which can be seen by sighting a straight line between Pyramid Rock which is located at approximately 21° 27'42" N / 157° 45' 48" W, and Kaoio Point which is located at approximately 21° 32' 03" N / 157° 50' 16" W.
