Regularly done, best to preserve night vision and not rely on searchlights but main thrust probably radar not turned on or not on correct settings or not being observed. Had crew been specifically briefed on that occasion to keep a lookout? Not easy navigating a boat like that in the conditions and trying to monitor all the kit yourself esp if your crew is useless. Some of our crew have been amazingly good and I would sail anywhere with them. I've trained em up to yachtmaster and they are now really good skippers. However some have been errr...b***y useless!
It was dark and the wind was gusting up to 45mph, with driving rain and rough seas
Should have been up and away before it ever got to that stage but been there and done that...commercial pressures and trying to get the job done/sudden increase in wind speed...but whatever the pressures its the skipper at the sharp end!
