As a general rule of thumb, you should proceed at a speed that will allow you to stop within your visibility range, i.e, if you can see 50M you should be able to stop well within 50 metres, AND sounding a fog signal of some sort

If you have a real pea souper, and cannot see anything, you need to be crawling along at minimum speed. Also when crawling along you will be able to hear so much better the sounds around you, waves breaking, fog signals etc.

Radar changes the equation somewhat, but still you should decide what is a safe speed, Rules of the road, # 6 is to do with safe speed, and #19 is navigating in fog.

I agree thick fog is scary to navigate in, just as driving is.

As said before, it takes a bit of faith in your own navigation skills, and the accuracy of your equipment to be able to do dead reckoning by compass, and log, but with practice you can do it. Steering by compass is an essential skill in my mind, and should be practiced by anyone with a craft, no matter the size, as you are likely to need it at some point

The Lowrance GPS antenna gave up and we were navigating with a Garmin Etrex and iPhone. It certainly makes you realise how dependant you are on Electronics in a rib. Even if we had paper charts a compass Is not much use without reference points. !!

iPad mini in a marine case with Navionics App is the plan going forwards.
Should have let me know you were coming! And there was I home alone, no wife, no dog and waiting for the rugby to start!

We carry a Garmin Montana c/w Bluechart as a backup. I don't as a rule carry paper charts on the boat. If you are truly stuck in thick fog, charts are useless regardless of what the experts say (armchair or otherwise). What did we do before electronics? We hit f**cking rocks or each other and sank, that's what we did. That (and the U boats) would account for the 250 000 odd charted wrecks (all skippered by "proper seamen") around our coastline giving the best wreck diving in the world.
Unless you are keeping a meticulous log (yeah right) & know where you are & mark it every minute (on a 20knot+ RIB passage, give me strength) If it suddenly all goes dark grey you're fecked, anyone who thinks other wise is kidding themselves. Knowing you're lost is arguably safer than the bloke carrying charts who thinks he knows where he is.

I'll get me coat

It's scary stuff. There's a thread on here somewhere, where Roy Cruse, Bob Keeper and Myself got caught in thick fog coming back from Kynance to Mylor. We were so concerned about hitting anchored shipping in the Bay and Carrick Roads, we were comm'd back to Mylor by Falmouth Coastguard who had us and the ships on radar.

I'll go with that. We continued at such a speed, that if we hit anything, it wouldn't do any damage.

I have been sailing/Navigating at sea on large vessels for 28 years, and only in the last 10 years have we used electronic charts (and even today our primary means is STILL paper charts)
I guess we must have been lucky then
What did we do before GPS was invented (again not put on ships before about 1992, in my case)? I have never been aground in fog, or hit someone else in fog, or at any other time for that matter.

I have navigated using sextants, and a chronometer with a set of tables and calculator, and it can be done. you have to believe and have faith in what you do.

Interestingly very few wrecks are on the coast, the vast majority are more than 1 mile off shore, so that sort of means they didnt hit the rocks and sink in fog then......

I guess then that if you hit fog the best thing to do would be to drop anchor and sit it out .
Or is that the wrong thing to do.
