Three fishing vessels have run aground on the reef at Kammer Beach on Tinian in the Northern Marianas after strong winds broke them free from their moorings in Tinian Harbour.
The winds were brought by a tropical storm passing the northern part of the CNMI late last week.
No one was in the vessels when the incident happened.
The Department of Public Safety and Commonwealth Ports Authority safely secured two of the vessels on Friday.
The Tinian mayor's information officer, Cassandra Cabrera, says the third vessel, Il Sin Ho, was not secured and remains stuck on the reef.
Ms Cabrera says the boat will most likely remain on the reef and sink.
