So its 6 in the morning here in Southampton.
Ive been awake for the last hour (partly because im off to work in a minute)
All i can hear is a ship's horn every 2 minutes. I live a miles from the sea front.
What on earth!? Its probably foggy, but with the technology we have surely it shouldnt be necessary to sound the horn every few minutes!? Urgh, glad its not my day off.

If you want to be pedantic it’s a ships whistle, not a fog horn & yes, they’re very much still in use.

Some whistle!

Wasn't it the original Queen Mary's that could be heard 10 miles away? That would get Southampton out of bed. grumpy

Huh?

I have no idea what your "ffs" is for.
Is that your reaction to people asking questions in real life, or just on the internet?

Ive heard them before, usually in the evening.
I assumed there was some legacy regulation that meant a ship had to sound its horn whistle when leaving and entering a mooring. (which I thought was quite cool)
However this morning was quite extreme.
A £100m (a guess?) ship surely has enough radar, sonar and transponders on board to track other vessels for 100s of miles around. why is it nessesary to continually sounds the horn whistle?
No body is going to be rowing across the English channel at 5 in the morning.

Because ships big and small still smash into one another and not all ships will have that technology.

They will (generally) all have people with ears on board.

Oh ek.
But the yachts wouldnt have been moving at the time, so the horn of the ferry wouldn't have made a difference, right?

The big stuff can't stop very quickly and the small stuff won't have the same tech on them, ships whistles are still very much needed.

They are also very handy to show the intent of where they want to go, stops people guessing and crashing smile

Believe me, when the fog comes down and you are in a 38ft sailing boat, you are very happy to hear a large ship using its whistle.

You're supposed to sound signals in fog so other boats know you're there, you'd be surprised how many yachties will be out and about at silly o'clock and few of them will have radar etc...its more for the benefit of others so they can gauge where you are and what you're doing.

Similarly with manoeuvring in harbour in normal visibility, it's to let others know what you're doing, just like using your indicators.

If it was loud it was probably a big'un, all the more reason for them to sound fog signals, and anyway the people living near the waterfront pay a premium for the nautical experience, it'd be a shame to disappoint them!

As good as modern RADAR is it cannot pick up some small vessels if they do not have a reflector. Also small vessels can be hidden in amongst interference on the Radar. Even with the best Radar systems they still have to be tuned using gain, sea clutter and rain. There is also different pulse lengths, wiper settings and various other settings. The ships whistle gives a warning to vessels in close vicinity. The main reason vessels sound the whistle is that if they were in an incident the MAIB would rip the officers apart. In most vessels it is extremely difficult to hear the whistle on another vessel.

Ok, I feel enlightened. (also very interesting)

So are there different signals to mean different things? (turn left, change speed, turn right etc?)

Yes. Three short (S) for astern, for example. Heard that from someone (in a car) backing out of a paring space once and made me chuckle. Old habits die hard I suppose.

But yes, the point is that it is as much for the benefit of smaller and less well-equipped vessels, as much as the vessel sounding the signals.

If I misunderstood you, I apologise.

I read it as bloke lives near Southampton and complains about the noise ships make.

I live by the sea and a port and we had people complaining about the fog horn.

As I say, if I read your post wrong, I apologise
