Last night I could hear the fog horn and it got me wondering:

A) how do they work, is it compressed air blowing down a sort of bugle?

B) how do they work? You sailing a boat and hear a horn, so you take what course of action? Keep left, keep right, go straight?

The International Regulations for Preventing Collisions at Sea said:
19. Restricted visibility
(a) Rule 19 applies to vessels (not in sight of one another) in or near restricted visibility.
(b) All ships shall proceed at a safe speed for the condition of visibility (see Rule 6). A power-driven vessel shall have her engine(s) on stand-by for immediate manoeuvre.
(c) All ships shall comply with Section I of this Part e.g., Rules 5 (lookout), 6 (safe speed), 7 (risk of collision), 8 (action to avoid collisions), 9 (narrow channels), and 10 (TSS) with due regard for the visibility conditions.
(d) If another vessel is detected by radar alone, and a close-quarters or collision risk is suspected, a vessel should take early and substantial action to avoid the other, but:
(i) avoid any turn to port for a vessel detected forward of the beam, except for a vessel being overtaken,
(ii) avoid any change of course toward a vessel abeam or abaft the beam.
When the fog signal of another vessel is heard, apparently forward of the beam, a vessel should reduce speed to the minimum at which she can maintain her course, or if necessary stop, and navigate with extreme caution until there is no risk of collision.
The rule is to turn to starboard so that the ship you are about to hit passes to port.

Pass the port eh? Capital idea.

Or switch on the radar of course, working on a sea near you since 1939.

Well yes, that would be an option. Certainly the average PHer's Bond Villain-style superyacht would be so equipped.

There is one on the Thames around the Greenhithe area. Bloody thing.... from my sleep point of view.

Turn off the radio/cd player/mp3 player immediately and go and find some proper music to listen to

Ah yes...can be a little disruptive if you live by the water, our front door to Southampton Water is about 70mtrs, hence at night when its foggy we get to hear quite a lot of honking! (I'm not complaining mind, I love it).

+1

Living on Guernsey, you can't avoid hearing them. I find it quiet soothing at night.

best fog horn/horn I have heard is the one fitted to the Disney Dream cruise liner... That thing can play Disney Tunes as it leaves port. I thought that was a pretty neat little feature. Certainly got a lot of cheers.

Beautiful looking ship for a floating butlins camp as well. Butlins is probably too harsh... the new cruise boats are more like water going vegas hotels.
