Just looking at uk wind map and Irish sea has 20ft waves and according to live ais there are a fair few vessels out there but do any of the ships have live webcams on board out of interest?
I think that only cruise ships have "live" webcams normally for the entertainment of passengers. Can't see why other ships would need one plus the additional expense of maintaining a satellite link. Some I believe have CCTV for docking purposes but not webcams that the outside world can view.
