National flags or ensigns
The vessel's national flag - not necessarily the same nationality as the skipper or owner - should be displayed at the stern of the yacht; however on traditional yachts, placement on the main leech or gaff is historically more correct.
If the crew's nationality differs from that of the yacht, the crew's national flag can be flown under the courtesy flag at the starboard spreader. Likewise the nationality of an important guest on board is displayed this way.
Note that the European flag should not be used, since it doesn't refer to a nation.
Flag and ensign are synonymous. The name ensign is derived from the French enseigne and Latin plural insignia.
Courtesy flags
When in foreign waters the courtesy ensign, often the national flag of that country, is hoisted under the starboard spreader of the most forward mast. On a mastless powerboat, the courtesy flag replaces any flag that is normally flown at the bow.
Like the national flags or ensigns, the courtesy flag is hoisted at 08:00 local time and lowered at sunset. Yet, when manoeuvring - for example entering or leaving port - the national flags should be flown even at night until your ship is out of sight or safely at dock.
Q flag
The yellow Q flag should be flown instead of the courtesy ensign until the yacht is properly cleared by customs and immigration, after which the Q flag is replaced by the courtesy flag.
Burgee
The - often triangular - burgee from the skipper's yacht club or sailing organisation is also hoisted at the starboard spreader, but below the courtesy flag. International yacht club burgees are often hoisted above the nationality flags of crew or guests. Yet, purists will say that also crew national flags should be hoisted above any burgee. Too avoid possible insult it is therefore best to fly your burgee below all national flags!
The burgee may be flown day and night.
International code of signals
First drafted in 1855, this visual system was first published internationally in 1857 and gradually adopted by most seafaring nations. The 1932 modernisation allowed for new situations like a medical distress call involving radiation casualties (AN 2). Some other interesting examples: (IT): I am on fire; (US 4): Nothing can be done until weather moderates; (GM): I cannot save my vessel; (NC No and Yes) is used as a distress signal.

Though, in nearly all countries the white & blue A flag is used as the diver's flag, which is only technically correct if the divers are physically connected to the vessel with an “umbilical cord”, preventing the vessel from manoeuvring.
The red flag with the white stripe is only official in Canada, Italy and some states of the USA, but since it aims to protect the divers below instead of the vessel, many divers choose wisely to hoist both flags.
