Marc Anthony Sued: Your Yacht Left Me with 9 Fingers

Marc Anthony makes a crummy ship captain -- so says a former employee who claims he lost a finger working on the singer's boat.

Jean-Pierre Perret says in a new lawsuit he was a member of the crew back in March 2015 on Anthony's yacht "Seas The Day." Perret says he was helping repair the boat's busted anchor when something went terribly wrong ... and a digit on his right hand went overboard.

Perret says it was Marc's responsibility to make sure the boat was shipshape. He says he was never warned the anchor could be so dangerous.
