Compare the following with that from Hugill posted above by Jim Dixon in 2008:

THE SEAMAN’S ALPHABET

CHANTEYMAN:
A is the anchor that hangs on the deck. [sic
B are the bulwarks, as we all know.
C is the capstan that we push around.
D is the deck where sailors are found.

CHORUS:
Hi, derry! Ho, derry! Hi, derry down!
Give a sailor his grog and there’s never a frown.

E is the ensign that flies at the peak.
F is the foc’sle where sailors do sleep.
G are the guns where at stations we stand.
H are the halyards we sailors do man.

I are the irons where stuninsils boom ship. [sic
J are the jibs where we often get dipped.
K is the keelson we’ve often been told.
L are the lanyards we lay a firm hold.

M is the mainmast, so stout and so strong.
N is the needle that never goes wrong.
O are the oars we all bend our backs.
P are the pantiles we scarcely can crack.

Q is the quarterdeck where officers meet.
R is the rigging, so taut and so neat.
S are the stuninsils that send us along.
T are the topsails we hoist with a song.

U is the Union Jack we all adore.
V is the vane we fly at the fore.
W is the wheel, where we we all do our time.
X, Y and Z we can’t get to rhyme!


From the Hartford [Conn.] Daily Courant (Apr. 12, 1935), p. E3. The columnist writes,

“[T]hough several lines point definitely to it being British, and to have originated on a man-of-war at that, [it] was chanted…by the late Captain Cephius Ball of New London, a splendid ancient mariner who sailed all his active days on American ships.”

Fun fact: The official name for the flag flown at the jackstaff of U. S. Navy vessels in harbor was and is the "Union Jack."

It consists of the stars from the Stars and Stripes, without the stripes.
