On January 6, 2010 the vessel was involved in a collision at sea with the MY "Ady Gil" which was participating in Sea Shepherd operations against Japanese whaling in the Southern Ocean. Out of the crew of six from the "Ady Gil", one New Zealand cameraman sustained broken ribs. The "Ady Gil" sank soon after. The third vessel at location, Sea Shepherd's "Bob Barker", and the "Shōnan Maru 2", took footage of the incident. Video of the incident has been released by both Institute of Cetacean Research and Sea Shepherd Conservation Society.
