The Kiwi captain of an anti-whaling boat sunk last month has clambered aboard the Japanese security ship that rammed his boat.

Multimillion-dollar protest boat Ady Gil was hit by the Shonan Maru 2 in the Southern Ocean on January 6, injuring a Kiwi cameraman on board.

The Ady Gil's skipper, Pete Bethune, called the collision "attempted murder" of the boat's six crew members.

Debate on this issue is now closed.
