Oahu Most of Oahu’s deep sea fishing is available off the island’s Leeward Coast. Charters depart from Kewalo Basin in Honolulu, about one to two miles from Waikiki, or Ko Olina on the west side of the island, about 35 miles from Waikiki. The largest reported marlin ever caught was near Ko Olina and weighed 1,805 pounds!
