Frequently Asked Questions (FAQs)

1. What flag should I fly on my boat?

United States Ensign The U.S. national ensign, sometimes called "50-star" or "Old Glory," is the proper and preferred flag for all U.S. vessels. Your boat should wear it from 0800 until sunset, and when you enter or leave port during daylight or at night, weather and rig permitting.

2. What are the flags on a boat called?

A maritime flag is a flag designated for use on ships, boats, and other watercraft. Naval flags are considered important at sea and the rules and regulations for the flying of flags are strictly enforced.

3. What do boat flags mean?

For example, if you see the A (Alpha) flag, this means “diver down, keep clear.” If you see the W (Whiskey) flag, the boat has a medical emergency and needs help. The combination of the D (Delta) and V (Victor) flags, meanwhile, means “I'm maneuvering with difficulty and require assistance.”

4. Why do boats fly flags?

Some boaters use signal flags to dress their ships for holidays by hoisting the national ensign at the stern staff first. A rainbow of flags can then be arranged, reaching from the waterline forward to the aft, from the bowsprit end (or stem).
