Boarding?
Just how did they board a ship at sea? Its pretty much impossible to do this from another ship (let alone the sort of inflatables Greenpeace and co usually use) without the assistance of the crew.
Since I assume the protesters didnt point guns at the crew, and demand to be let on board, they would have been allowed on by permission. In which case, unless they actually comitted a crime (under maritime law) on board, holding them is kidnapping. Interesting...
