On April 5, 1824, King Kamehameha II’s royal yacht, Pride of Hawaii, sank near the mouth of the Waiʻoli River, 22°12′14″N 159°30′37″W / 22. 20389°N 159. 51028°W / 22. 20389; -159. 51028 (Waioli River mouth), on the southwest corner of the bay after its crew struck a 5-foot-deep (1. 5 m) reef a hundred yards offshore. It is believed the captain and crew were drunk at the time. A large section of the ship’s hull washed ashore in 1844 in a winter storm surge, but most of this historic wreck remains buried in silt in the bay. In 1995–2000, archaeologists from the Smithsonian Institution’s National Museum of American History excavated the wreck and recovered more than 1,200 artifacts. During this excavation, a 40-foot (12 m) section of the stern was discovered, documented, and then re-buried where it was discovered.
