Certain rules follow certain types of fish so make sure you read up on the fish flag etiquette in fishing manuals. [links]
This will also keep it clear from the rigging.
The yacht owner can also fly their own national flag on the boat. It can be placed on the starboard spreader, but if the owner deems it appropriate it can be flown on the port side, as it is a flag of lower importance (than the ensign). more
All other flags are flown under the port spreader. So what are the other flags you can fly on the yacht? here
This flag should be flown in the correct manner from sunrise to sunset. It must always be hoisted first and lowered last. No other flag may be flown unless the national flag (ensign) is also flown. more
Where is it flown?
When a vessel has no flag, it could mean that it is not registered and therefore there is no control over the vessel, the equipment of the crew might not be certified or there might be issues of safety or pollution. But still it does not mean that, in international waters, other ships could treat the vessel like a pirate, or anybody can seize the vessel for having no registration. Some scholars believe that the freedom of navigation in high seas (in customary international law) belongs to states and not individuals, which means unregistered vessels are not free to navigate since they are not under any state.

Would being unregistered vessel mean, that other ships could treat me like a pirate, or nobody can seize me for having no registration until I'm on international waters?
A ship's flag state exercises regulatory control over the vessel and is required to inspect it regularly, certify the ship's equipment and crew, and issue safety and pollution prevention documents. The organization which actually registers the ship is known as its registry. Registries may be governmental or private agencies, or in some cases, a third party is administered to do the inspections. here
However, there are another kind of vessels: vessels without flags. I quote this part from [Bennett, Allyson. "That Sinking Feeling: Stateless Ships, Universal Jurisdiction, and the Drug Trafficking Vessel Interdiction Act." Yale J. Int'l L. 37 (2012): 433], who says: [links]

When it comes to nautical flags, there are a few dos and don’ts. Naturally, you’ll want to brush up on your sailing flags and what they mean, and where and when to use them. But there are a few other etiquette rules that most books don’t teach you. Here are a few important things about maritime flags: [links]
However, when operating internationally, say going to the Bahamas, once in foreign waters you are required to fly the “Q” Flag or “Quarantine Flag” until you have cleared customs. This flag should be hoisted on the starboard spreader. If you are on a power boat with no mast, the “Q” flag can be displayed on the bow. here
Although you may never see them displayed except at fleet parades, around naval installations, and areas with heavy international shipping traffic, International code flags are used to signal between two ships or between ship and shore. Also called signaling flags, they are a set of ship flags of different colors, shapes and markings which used singly or in combination have different meanings. These maritime flags include 26 square flags which depict the letters of the alphabet, ten numeral pendants, one answering pendant, and three substituters or repeaters.
Customs regulations and clearance procedures and costs may differ from one foreign country to another. Be sure and check your cruising guide for the proper procedures or try inquiring locally by radio prior to entering a foreign port. Although I have found that most custom officials speak some English or have access to someone who does, don’t forget that you are in their country and you should be prepared to communicate with them in their language.
Don’t fly a foreign courtesy ensign after you have returned to U.S. waters. It may show that you have “been there,” but it is not proper flag etiquette.
