The American flag is one of the most recognized symbols in the world, and the rules governing its display are among the most detailed of any national ensign. For vessel operators, yacht clubs, marinas, and waterfront businesses, proper flag handling goes beyond civic custom. Maritime flag etiquette carries operational and professional significance rooted in centuries of seafaring tradition.
Established under Title 4 of the United States Code, Chapter 1, the Flag Code provides official guidelines for how the flag should be displayed, handled, and retired. The code is advisory rather than criminal law. Its language uses terms like "should" and "custom" throughout, meaning violations carry no federal penalty. That said, following the code reflects genuine respect for the flag and the values it represents. For mariners specifically, proper flag etiquette is a mark of seamanship and professionalism observed at every port.
What Is the US Flag Code?
The United States Flag Code was first adopted by Congress on June 22, 1942, consolidating earlier civilian and military flag customs into a single federal statute. The code has been amended multiple times since, most recently in 2017, and covers everything from how to hang the flag on a wall to how to dispose of a worn flag with dignity.
The code applies to all Americans, from private citizens flying a flag on a front porch to government agencies, businesses, and maritime operators. For those operating on the water, the Flag Code works alongside additional maritime customs and vessel-specific flag display protocols that govern ensign placement, courtesy flags, and signal pennants aboard ship.
Core Display Rules
Raising and Lowering
The flag should be hoisted briskly and lowered ceremonially. Standard display runs from sunrise to sunset on buildings and stationary flagstaffs. The flag may be displayed 24 hours a day if properly illuminated during darkness. During inclement weather, only an all-weather flag should be flown.
Orientation and Position
The union (blue field of stars) must always be uppermost and to the flag's own right (the observer's left) when hung flat against a wall, whether horizontally or vertically. When displayed on a speaker's platform, the flag occupies the position of honor at the speaker's right.
Per 4 U.S. Code Section 7(c), no other flag or pennant may be placed above the American flag or in a position of superior prominence, with one notable exception: during church services conducted by naval chaplains at sea, the church pennant may fly above the national ensign. This is one of the oldest customs in the U.S. Navy and the only recognized circumstance under federal law where another flag takes precedence over the Stars and Stripes.
Prohibited Uses
Per 4 U.S. Code Section 8, the flag must never touch the ground, floor, water, or merchandise beneath it. The flag must never be carried flat or horizontally, but always aloft and free. The flag must not be used as apparel, bedding, drapery, or for advertising purposes. The code specifically states the flag should not be draped over the hood, top, sides, or back of a vehicle, railroad train, or boat.
Half-Staff Protocol
Flying the flag at half-staff is one of the most visible gestures in American civic life. The president holds the authority to order flags to half-staff for national observances. State governors may do the same within their states.
On Memorial Day, the flag flies at half-staff until noon, then is raised to full staff for the remainder of the day. The flag flies at half-staff for 30 days following the death of a sitting or former president, and 10 days for the vice president, chief justice, speaker of the House, or similar senior officials. For members of Congress, the flag flies at half-staff on the day of death and the following day.
The proper procedure requires hoisting the flag to the peak first, then lowering it to the half-staff position (defined as one-half the distance between the top and bottom of the staff). Before lowering for the day, the flag must be raised to the peak one final time.
Displaying the Flag on a Vessel
Maritime flag display follows customs that predate the Flag Code itself. Aboard vessels, the national ensign serves as the primary identifier of nationality and carries both legal and ceremonial significance under international maritime law.
Powerboats and sailboats at anchor or dockside fly the ensign from the stern staff. Sailboats underway traditionally fly the ensign from the leech of the aftermost sail or from the stern staff. Vessels with a gaff rig fly the ensign from the gaff while underway. On most modern vessels, the stern staff remains the standard position.
When entering or operating in foreign waters, vessels fly a courtesy flag (the national flag of the host country) from the starboard spreader as a mark of respect. The American ensign continues to fly from the stern. The courtesy flag should be the same size or slightly smaller than the ensign, and per the Flag Code's guidance on displaying flags of multiple nations (Section 7(g)), flags of two or more nations should be flown from separate staffs of the same height, with international usage forbidding display of one nation's flag above another in peacetime.
Signal flags, yacht club burgees, and officer pennants each have designated positions in the vessel's flag hierarchy. The Q flag (solid yellow) indicates a vessel requests customs clearance, a common sight in Caribbean waters and at international ports. For complete guidance on maritime flag positions, the ANS blog covers American flag display rules on vessels in detail.
The Union-Down Distress Signal
Section 8(a) states the flag should never be displayed with the union down except as a signal of dire distress in instances of extreme danger to life or property. On the water, this provision has real operational weight. A vessel flying the ensign union-down communicates distress to other mariners in the same tradition as other visual distress signals. While modern vessels rely primarily on VHF radio, EPIRB, and electronic navigation equipment for emergency communication, the inverted ensign remains a recognized visual signal.
Proper Disposal of the Flag
When an American flag becomes worn, faded, torn, or otherwise unfit for display, it should be retired with dignity. The Flag Code states the preferred method is burning in a dignified ceremony. Many Veterans of Foreign Wars posts and American Legion chapters hold regular flag retirement ceremonies and accept worn flags for proper disposal. Mariners who fly ensigns in demanding marine environments, where salt, UV exposure, and wind accelerate deterioration, should inspect flags regularly and retire them before they become unserviceable.
Displaying Alongside State and Organization Flags
When the American flag is displayed with state flags, city flags, or organizational pennants, the national flag must always be at the highest point and hoisted first. On the same halyard, the American flag occupies the peak position. On adjacent staffs, no other flag may be placed above or to the right of the American flag. For vessels and facilities displaying state flags like the Florida state flag alongside the national ensign, proper hierarchy and sizing ensure compliance with both the Flag Code and established maritime custom.

FAQs
Q. What does a black and white American flag mean?
Black and white versions of the American flag are not addressed in the US Flag Code and carry no official status. Monochromatic flags have appeared in various contexts, from mourning to law enforcement solidarity. Because these designs fall outside the Flag Code, their display is a matter of personal expression.
Q. Can the American flag be flown at night?
Yes, provided it is properly illuminated. A spotlight, floodlight, or similar light source directed at the flag satisfies this requirement.
Q. Is it illegal to violate the US Flag Code?
No. The Flag Code is advisory. No federal penalties attach to violations by private citizens. State flag desecration laws have largely been ruled unconstitutional under First Amendment protections.
Q. What is the only flag that may fly above the American flag?
The church pennant, flown during religious services conducted by naval chaplains at sea, is the only flag permitted above the national ensign under 4 U.S. Code Section 7(c).
Q. Where can marine-grade American flags be purchased?
American Nautical Services stocks American flags, courtesy flags, signal flags, and specialty pennants designed for marine environments, along with reference publications covering maritime flag protocol.
