First - as soon as you are navigating in or near an area where the visibility has dropped below 1,000m (further than you might think) there is a fundamental change in how the rules of the road apply. Rule 19 of the International Regulations for the Prevention of Collision at Sea (IRPCS) effectively means that in these circumstances all the usual rules regarding stand-on and give-way vessels change to everyone becoming give-way vessels. After all, if you can't see them clearly, how can you tell their intentions?
Second - your speed must be adapted to suit the visibility, meaning you must be able to comfortably stop within the distance you can see. So in open sea with just under 1,000m visibility that might not require any change of speed but if the location, traffic density or depth complicates things then somewhere between 6 and 10 knots may be more suitable. Any slower than that and you may have difficulty holding a straight course.
Your next steps should be to confirm your position and note it on a chart or logbook, turn on your navigation lights, ensure your crew are wearing lifejackets, switch on your radar and AIS if fitted, and comply with the correct sound signals. Lastly, ask all aboard to keep a look out using all available means.

Lofoten or Bust- Part 4- Grandezza owner Per Harrtoft heads back to Sweden after an epic 3500nm adventure deep into the Arctic Circle to visit the mythical Lofoten islands
After ten memorable days in the Lofoten Islands in the far north of Norway, we are on our way back south towards Sweden. We have already made it as far as Trondheim, a charming place even if it was raining so hard we had to cycle round the city centre clutching umbrellas. But now we are back on board Deamare, our Grandezza 40 Fly, eating up the miles at a steady 31 knots.
