Small craft have plenty of anchorage room in the unimproved areas behind the breakwaters.
Marine supplies and repairs, fuel and water are available for small craft at Kahului.
Kahului Harbor on the S side of Kahului Bay 6 miles SE of Mokeehia Island, is protected by breakwaters which extend outward from the W and E shores. On the SE side of the harbor is the commercial deepwater port of Kahului.
Pauwela Point Light (20°56’44″N., 156°19’17″W.), 161 feet above the water, is shown from a 40-foot white post 9 miles ENE of Kahului Harbor and is the principal mark for the approach. Other marks are an aero light at the airport E of Kahului, the breakwater lights, the lighted entrance range, the powerplant stacks E of the piers, the radio tower 0.8 mile W of the rear range, and the Wailuku spire and stack 2 miles W of the harbor.
From deep water on the N, the channel leads between the breakwaters, then turns sharply SE to the Kahului piers. A Federal project provides for an entrance channel 35 feet deep and a harbor basin of the same depth. Channel and basin are maintained at or near project depth. Navigational aids include lighted and unlighted buoys, breakwater lights, and a 176.8° lighted range. A channel, marked by private buoys, leads to a boat ramp at the W end of the harbor.
Waihee Reef NW of the breakwaters, and Spartan Reef NE of the breakwaters, extend 0.7 mile and 1.2 miles offshore, respectively. Vessels approaching the harbor entrance range from either direction should avoid the reefs. The W part of the inner harbor is shallow. There is a buildup of silt and marine debris (old tires) that creates a shallow area in the SE corner of the commercial harbor in about 20°53’44″N., 156°27’56″W.
Kahului is a customs port of entry.
