Mine tells me plenty about what's going to happen.
Agreed. I meant to say the same when I read that post!

Just because the electronics allow one to do something doesn't make it sensible?
I agree that planning to do it that way would not be very sensible but, when necessary, I have done it. Unfortunately I can't control the weather at the end of a passage.
There was a time when sailors would have diverted to another destination or stood off and waited for better visibility or where feasible and safe would have considered anchoring in deeper water under those circumstances. However it seems we are now down to discussing exceptional situations rather than normal good practice? This all started with suggesting that the compass was one of the most useless items on board and on that topic I still strongly beg to differ.
As I said before, we all cut our own wakes which is just another way of me trying to say 'each to their own'.
I would suggest that at one time a compass was essential to any boat sailing but has times and equipment have evolved it has now become a back up rather than a primary means of navigation unless you are teaching or running a course.
Yes we all still need one but in most circumstances it is rarely used.
I would probably think far, far less than 50% of boats have had their compasses set up or adjusted in the last few years and you will be lucky to find or remember where you put your deviation card.
The best aide to navigation has and will always be the human eye and brain... that is unless you have my brain
If you really believe that is true, perhaps we should have a cruise in company on identical boats. The reason I say this is that the plotter with its GPS will tell you where you are and where you are going and which direction your destination is, but unless you are running some fancy realtime software with tides and tidal stream predictions, if your track takes you over more than one tide you need to do some traditional calculations to arrive at a course to steer. And although some people will protest that their fancy software will do the correct calculations, 99% of the boaters I come across just follow the track which is easily shown to be a slower way to get there.
People can convince themselves they don't need a compass and they can get away without using a compass but they are not passage planning or steering very efficiently some of the time.
The plotter can be very good at doing simple COG/SOG and BTW calculations, but it doesn't always realise that allowing your boat to go several miles 'off track' might be quicker in the long run.
John, as I say, we are cruisers not racers and our ETA anywhere will be within several hours. We do not rush, often stop for lunch and don't have to work out a course to the nth degree. I have checked for obstacles before setting of so the rest of the time is spent enjoying the journey.
It was slightly different in Britanny and Atlantic but not much.
As I say eyesight is the primary navigation tool as you were forever avoiding pots, nets and fishing boats. You would be forever doing new calculations if you were only using a compass.
We will have to agree to differ. We don't race any more and I certainly don't do new calculations all the time, but if you cross the channel from Plymouth to L'Aberach etc over two or three tides the difference in your passage time between doing some simple calculations and just following the track on the plotter might be over an hour in your passage time. That's time spent at anchor with your feet up with a glass of something and certainly not to be sniffed at. Of course you can cruise in any style you like, but I am concerned that there are more and more sailors coming to the sport who don't understand the points I am making and rely on the toys to the point that they consider the compass to be superfluous. If people start believing that it would be a disaster waiting to happen. Sailing for personal pleasure in the UK has been unregulated for years because sailors have been sensible and not done stupid things on the whole. When I read that people have started to think that their compass is superfluous I get really worried for all the reasons I have already explained.

Is that because "everyone" has autopilots these days? I'd say that the compass is the only instrument on board I use more than the echosounder - but then I steer by hand or occasionally with an ancient Navico standalone tiller pilot.

+1.
Steering by hand and getting the best out of the boat, playing the windshifts and tacking up the compass angles to a destination.
Utterly pointless of course.
( tbh even tho most boats can be pursuaded to steer themselves. Just the fun of one eye on the compass, one on the telltales and a hand on the helm... Pah, its all so retro!

For what it's worth I'm with you 100%.
As I read this thread I assumed the first reference to the compass was an attempt at ironic humour.
I'm the furthest thing possible from a technophobe, and I absolutely love what modern sailing electronics can do. I well remember a spring series race started in perhaps 200m vis, probably less. That we weren't struggling to find the mark, but hit the layline just as normal was a very, very impressive demonstration of just what is now possible. And most of my cruising is done with a chartplotter at the helm with radar overlay and an all singing all dancing linked autohelm. But I would never dream of pushing "track" on the autohelm without first glancing at the compass to check that it seems right.
Like John, the idea that there are a considerable number of sailors out there who regard the compass as unnecessary gives me the shivers.
I do often have competitions with my auto pilot when I set it to wind mode.
It is pretty good and at the moment I am winning but only just. I pinch the wind far too much.
On the whole it steers a pretty good course by the wind but just bleeps too much when there is a windshift.
