This incident may be a bit old and we remember this happening, but somehow we have never seen the video before.
In the video the 68,789 dwt bulk carrier, Grand Rodosi, absolutely destroys the much smaller tuna boat, Apollo S, while moored at the wharf in Port Lincoln, South Australia. The Apollo S quickly sank (at least once the Grand Rodosi had unpinned it) and the wharf was damage in the collision.[youtube]http://www.youtube.com/watch?v=svFwsJsHHGs[/youtube]
