The owners of a sailboat and barge that collided in Biscayne Bay on Monday, killing two young girls and critically injuring two other girls, are working with commercial salvage to draft a plan to have both vessels removed, according to the U.S. Coast Guard.

Disturbing new video shows the horrific moment a barge crashed into a sailboat off the coast of Florida, killing two young girls and critically injuring two others. Surveillance footage shared by NBC Miami shows the barge slamming into the sailboat that was carrying a 19-year-old instructor and five kids as part of a sailing summer camp on Biscayne Bay near Miami Beach on Monday.

Two children were killed and two more are in critical condition after a barge struck and sunk their boat, sending them overboard during a sailing camp in Miami on Monday, authorities said.
