PLYMOUTH, Mass. (AP) - A crewless robotic boat retracing the 1620 sea voyage of the Mayflower has landed near Plymouth Rock.

The sleek Mayflower Autonomous Ship met with an escort boat as it approached the Massachusetts shoreline Thursday, more than 400 years after its namesake's historic journey from England.

It was towed into Plymouth Harbor - per U.S. Coast Guard rules for crewless vessels - and docked near a replica of the original Mayflower that brought the Pilgrims to America.

Piloted by artificial intelligence technology, the 50-foot (15-meter) trimaran didn't have a captain, navigator or any humans on board.

The solar-powered ship's first attempt to cross the Atlantic in 2021 was beset with technical problems, forcing it back to its home port of Plymouth, England - the same place the Pilgrim settlers sailed from in 1620.
