Just seen this on the news:
Any idea what gear he would use? I'm thinking that the charter boat had a small crane on it and he was using that, although he may have been using a Steel hauser cable (not sure about breaking strain) and winch hook.
I would love to have been there when he brought it to the side of the boat though.
For video have a look here: http://youtu.be/mITQAh4XsuI
