About 0220 on July 24, 2016, in tropical storm conditions, the 70-foot-long small passenger vessel Spirit of Kona broke loose from its mooring in Kailua Bay on the island of Hawaii. About 10 minutes later, after drifting across the bay, the vessel grounded on lava rocks. Under continuous wave action, the Spirit of Kona broke apart and subsequently sank. No one was on board at the time. The vessel’s fuel and lube oil tanks ruptured and about 275 gallons of oil spilled into the sea and onto the rocks. The value of the Spirit of Kona was an estimated $1.1 million.
