When a ship arrives at its destination, how many times does it blow its horn, typically?

I am most interested in the answer pertaining to large passenger ships, like those that would cross the ocean.





But any help you can provide will be most appreciated.

When a ship arrives at its destination, how many times does it blow its horn, typically?
5 or more short blasts of the whistle is the danger signal!





other blasts of the horn have different meanings.





In international waters:


one short blast means i am altering courseto stbd.


2 short blasts means i am altering course to port


3 short blasts mean i am operating astern propulsion





here is a link to the USCG site for the rules of the road (colregs) that should be able to answer your questions.

Reply:Well differnt whistle blows could mean differnt things,some to get attention of other boats or a push tug or guys on the pier,, but they dont do it as much as they used to as radio has done a lot of replacement for it,,





Just like trains they had whistle blows like 2 short and one long meant something but most all that is radio and computer now as well

There is no requirement for "Entering Port"...what you will hear is one or two short blasts for each change of coarse...often referred to as "rudder signals". It lets everybody else know what the Captain's up to.
