In the summer of 1821, he was in a small boat intended for the ʻEwa beach, just west of Honolulu. A few nobles such as Chiefess Kapiʻolani and Governor Boki were aboard, with about 30 men. He ordered the ship to instead cross a dangerous channel all the way to the island of Kauaʻi, despite having no compass, charts, nor provisions on board. They somehow made it to Kauaʻi. When they arrived, the local Chief Kaumualiʻi did not fire his cannons on the unarmed ship but welcomed the young king. The Royal Yacht was sent for, and the royal party entertained themselves for over a month. Then one night after he invited Kaumualiʻi on board, Kamehameha II abruptly ordered the yacht to sail in the night. Upon returning to Honolulu, he had Kaumualiʻi "marry" Kaʻahumanu and kept him under house arrest in exile until his death.
