Ala Wai Boat Harbor is 2.5 miles NW of Diamond Head Light. A dredged channel leads from Māmala Bay through the reefs to the basins inside the harbor. In 1967, the channel was dredged to 22 feet. Depths inside the harbor are 8 to 20 feet. The approach to the channel is marked by lighted buoys and the channel is marked by private buoys, daybeacons, and a 013°30' lighted range. Mariners are advised to line up on the range before entering or exiting the harbor at night. During the trades, the winds within the harbor are distorted by the nearby tall buildings. Vessels maneuvering in the harbor under sail should beware of sudden changes in the direction and velocity of the wind. The harbor can be entered in all weather except during kona storms. During the summer months, very large swells can be found outside Ala Wai Harbor; mariners should navigate with the utmost caution during those times. The harbor is one of the most popular places for small-boat activity on O‘ahu, and yacht clubs in the harbor are the host for the famed transpacific yacht race. The harbor attendant controls the berthing and mooring facilities. [www.nauticalcharts.noaa.gov/nsd/coastpilot_w.php?book=7] Chapter 14
