So some of you guys don't think there is anything wrong with giving incorrect directions when you are the only guy who can see the boat (evidenced by the confirmation once clear that the pilot then had references). Although the clearance from the vessel should have been pre-briefed, things can change and without references the pilot can only follow the 'con' - if that is poor then the aircraft and casualty are in danger.
You call it sledging - we call it critiquing and any professional worth his salt should accept that, I do when I make a mistake (and no I'm not perfect). If people don't want their mistakes to be seen then don't release the video to be beamed around the world.
