According to a statement released Tuesday, the Coast Guard is looking into the brief grounding of the Expeditions IV, a ferry that runs between Lahaina and Lanai.

The statement says that while transiting the Lahaina Harbor channel, the vessel was lifted by a swell and hit a shoal. It returned to its mooring, and no one was hurt. It is now out of service.

The Coast Guard also is investigating an unidentified 46-foot catamaran that broke loose from its mooring at Lahaina Small Boat harbor, drifted approximately 100 yards and grounded on a reef.

No one was aboard at the time.
