On 6 February 2010, while obstructing the slip-way of "Nisshin Maru" factory ship, "Bob Barker" collided with "Yūshin Maru No. 3", resulting in a gash in "Bob Barker"s hull above the waterline. The Institute of Cetacean Research reported minor damage to a handrail and to the hull of its ship. Both Sea Shepherd and the ICR accused the other of intentionally causing the crash.
