Flag Signaling

Req 4c — Practice With Flags

4c.

After 4(a) and 4(b) have been completed, do the following:

This is the hands-on payoff for everything you learned in 4a and 4b. The two tasks are independent: one is about performing semaphore, the other is about identifying and discussing nautical flags. Work through both before your counselor meeting.

Requirement 4c1 — Semaphore Practice

4c1.

After 4(a) and 4(b) have been completed, do Spell your first name using semaphore. Send or receive a message of six to 10 words using semaphore..

You must complete both parts: spelling your name and sending or receiving a multi-word message.

Spelling Your Name in Semaphore

Each letter corresponds to a specific combination of arm angles. There are eight basic positions for each arm, giving 64 combinations—more than enough for the full alphabet.

How to practice:

Look up the semaphore alphabet chart (you’ll find it in the badge pamphlet or online).
Practice each letter of your name in front of a mirror until the arm positions feel natural.
Practice transitions between letters smoothly—return to the rest position (arms straight down) between letters.
Have a partner watch and confirm each letter.

Sending or Receiving a Six-to-Ten-Word Message

If you’re sending:

Write out your message before starting.
Signal the “attention” position first (both arms raised outward at 45°) and wait for acknowledgment.
Send each letter, pausing briefly at the rest position between letters and slightly longer between words.
End with the AR signal (end of message) and wait for R (received) from your receiver.

If you’re receiving:

Keep your eyes on the sender and read each arm position as a letter.
Write down letters as they come, grouping them into words.
Signal R when you’ve received the full message.
Signal IMI if you missed a word and need the sender to repeat it.

Semaphore Practice Checklist

Have learned all semaphore positions for the letters in my name
Can spell my name smoothly, returning to rest position between letters
Have written out a 6–10 word practice message
Can send or receive the message with a partner
Know the Attention, IMI, AR, and R control signals

Requirement 4c2 — Nautical Flag Identification

4c2.

Using illustrations or photographs, identify 10 examples of nautical flags and discuss their importance.

Picking Your Ten Flags

You need to identify 10 flags using illustrations or photos—these can be from a book, printed charts, or photos you take yourself. Choose flags that have clear visual designs and meaningful standalone messages, so your discussion with your counselor is substantive.

Good flags to include:

Flag	Letter	Why It Matters
Alpha	A	Diver down—boaters worldwide recognize this; ignoring it can kill a diver
Bravo	B	Dangerous cargo—warns all nearby vessels
Oscar	O	Man overboard—one of the most urgent emergency signals
Victor	V	Require assistance—the universal distress request
Whiskey	W	Require medical assistance—critical at sea
Quebec	Q	Vessel clear/requesting entry—used at every international port
November	N	No/Negative—used in multi-flag messages
Charlie	C	Yes/Affirmative—used in multi-flag messages
Juliet	J	I am on fire with dangerous cargo
Golf	G	I require a pilot

You could also include the small-craft advisory, gale, storm, or hurricane warning flags to round out a discussion of weather-related maritime signaling.

Discussing Their Importance

For each flag, your counselor discussion should cover:

What the flag looks like (its design/colors)
What letter it represents
What its standalone message means, if any
Why that message matters in a real maritime context
