On May 16, the 37 meter long passenger vessel Maui Princess (MMSI: 367331770) ran aground off the west coast of Maui near Lahaina, Hawaii. The Maui Princess had broken free from its mooring and went adrift before it went hard aground on a bar some 300 feet offshore. No reports of injuries.

Authorities dispatched a response team to the scene. They found the passenger vessel had not released any pollution, but still posed a high risk. A contractor was hired and begun removal of 2,500 gallons of diesel fuel off the vessel.
