Right after the accident, the mother ship fled and cut off lines to the smaller boats being towed.
In a statement, Navforwest said, "Despite evasive maneuvers to prevent the collision, PS-74 still accidentally hit the last dinghy. At that moment, the crew of the fishing vessel cut off their towing line, leaving behind 24 dinghies that got entangled with PS-74."
