An Old Bluejacket Tradition Long Gone: Tar Hats to Flat Hats
My affinity for early Twentieth Century U.S. Navy Uniforms, especially those from the enlisted ranks, is increasing even if I am financially restrained from pursuing my most desired pieces when they surface onto the market. On some rare occasions, an artifact that I would love to add to my collection is listed and flies beneath the radar of fellow collectors leaving me the opportunity and wherewithal to bring it home.
I have written several articles (including considerable research for each) related to elements of uniforms from the first few decades of the last century ranging from rating badges, enlisted jumpers and head coverings and yet there is much that I am still discovering. The overwhelming focus of this site has been directed at naval artifacts and my collection is heavily weighted with U.S. Navy artifacts however I cannot consider myself to be an expert in these areas. One item of the enlisted naval uniform that I have much to learn about is surrounding the dress blue cap, known by many as the “Donald Duck Hat” or simply, the flat hat.
To delve into the full history of enlisted headwear and the entire life of the dress blue cap, I would need to write a multipart series of articles in order to give the hat its proper due (perhaps that will be a future project?). For the purposes of this post and to reflect the pieces that I have in my own collection, this article will be constrained with a narrow and specific focus.
Though flat hats were an integral part of the enlisted naval uniform for well over a century, it has been more than a half-century since the Navy retired them from usage. The earliest references to the flat caps were seen in the Navy Uniform Regulations of 1833 as the Navy began to standardize wear for seaman and petty officers.

This wide-brimmed black hat was worn by enlisted sailors many years ago when the Navy first began. Painted with tar, the wide brim kept sun off a sailor’s face (source: Naval History and Heritage Command).
ART. 601. The outside dress clothing of the petty officers, seamen, ordinary seamen, landsmen, and boys, shall consist of blue cloth jackets and trowsers (sic), blue vest, blue cloth cap or black hat, black handkerchief, and shoes, when the weather is cold; when the weather is warm, it shall consist of white frock and trowsers, black or white hats, or blue cloth caps, as the commander may direct, having regard to the convenience and comfort of the crew, black handkerchiefs and shoes.
In the 1833 regulation, there is no specific mention of “flat hat” as the term itself wasn’t part of the vernacular in use regarding the headwear at the time. Of the two references (in bold) referring to blue or black headwear, the cloth cap is the early example of what we know today as the flat hat. “Black hat” is referencing the various broad brimmed black tarpaulin headwear that were worn for several decades by enlisted sailors in the mid-to-late 1800s. These are actually (sennit) straw hats that were coated with tar that provided the sailor with a waterproof head covering that could withstand the rigors of shipboard life. The caps were adorned with a ribbon that was the forerunner of the hat talley that would be seen on the flat hats.

As the uniforms evolved with technology, the hats advanced. Painting straw hats with tar began give way to new methods for waterproofing such as creating a tarpaulin cover. Further advancements that helped in the reduction uniform expenditures and conserving the very limited space aboard ship but allowing sailors to have a single hat instead by making the hat convertible from a standard sennit to a waterproof one. by fitting the hat with a two-piece cover fabricated from oilskin or oilcloth fabric provides the desired effect.

Aside from the black (flat straw) hats, sailors also began wearing blue cloth cap that was the forerunner of what was later known as the dress blue hat for enlisted personnel. By the time the American Civil War began, the blue cloth caps were the most commonly worn hats by petty officers and seaman. The long ribbons that encircled the black hats were transitioned to shortened (without the extended streaming tails) versions and some were adorned with the name of the sailor’s ship name (sans “U.S.S.”) added by hand using gold paint. Late in the Civil War, there were some instances of entire crews having their talley’s embroidered (with gold bullion) in lieu of the painted vessel names. The gold wire-bullion embroidery became common (though still not standardized) with for flat hats in the 1883 naval uniform regulations. Another aspect of the blue caps was that they were soft and formless leaving sailors to customize their caps to suit their individual style by adding stiffeners or filling (almost pillow-like) to give them a personalized shape. In 1866, the black hat tarpaulin hats were no longer used.

As the American Navy was advancing from wooden hulls and sail to ships made of steel and powered by steam, the uniforms worn by crews changed with their needs. Changes to the dress blue hat were made in 1883 that remained, keeping the flat hat’s appearance consistent for the next 40 years. The U.S. Navy didn’t have the uniform supply system in place that exists today (which truly came into being as World War II was looming on the horizon in 1940) leaving sailors subject to acquiring or even making various uniform components. Flat hats conformed to a regulation standard but would vary in the diameter of the top (9 to 11 inches) which differed as it conformed to the size of the sailor’s head. Dress blue hats included a broad leather sweatband that is seldom visible in surviving caps due to the cotton shirt lining that has been sewn in for both comfort and to conceal the damage to the cowhide (due to sweat and repeated, prolonged usage).

In the years leading up to the Great War, the flat hats became more standardized with cotton linings being sewn in at the manufacturers, effectively eliminating the variations of various printed patterns on the linings for subsequent caps. Still, sailors would either heavily customize their caps with almost gaudy embroidery and fancy needlework (typically on the crown) however such embellishments were unauthorized for wear aboard ship. Caps with these decorations were worn ashore and during liberty or leave periods. Though modern Navy regulations have all but eliminated the personalization of uniforms, sailors have always found a way to add their own custom touches over the last century and a half. Flat hats with such personal flair are exceedingly scarce and never fail to draw the interest of collectors.
Although they might appear to be, tally ribbons were never tied to flat hats. A closer examination of the ribbons reveal that the ribbon was wrapped around the outside of the cap (even with the sweatband), trimmed and the ends tucked beneath the bow that was already secured to the cap with a stitch. Once secured beneath the bow ribbon would be stitched around the circumference of the hat.

This flat hat has the post-1940 “U.S. Navy” tally.
In 1933, the design of the flat hats changed once again with more standardizing in the shape and materials of the hat. Gone from the flat hats were the broad, head-size dependent thin and very flat top along with the printed cotton fabric lining. Also, the rigid hat stiffeners were changed leaving a more slouchy, beret-like appearance. The design gave the hat a pronounced for and aft appearance with the front portion of the top rising upwards, seemingly drawing more attention to the tally. The tallies also experienced a material change from the gold bullion wire ship and command names in favor of a gold colored thread, producing a low-profile lettering across the face of the talley that did not discolor with tarnish or verdigris. By 1940, the U.S. was rapidly growing its forces and building ships in an effort to catch up to the immense threat that was spreading in Europe and the Pacific. Ships of all classes were under construction in shipards up and down both coasts. To reduce the difficulties in managing ship identifyers for enlisted caps for each existing, under construction and planned naval vessel, the decision was made to eliminate the ship names from tallies and replace them with “U.S. Navy.” It has been suggested that this change was done as a security measure surrounding ship-movement but the notion that the presence of uniformed sailors in a port would be more obvious than the large battleships or aircraft carries is somewhat ridiculous.
One of my most recent flat hat acquisitions was one that I happened upon a few hours before the online auction listing was set to close. The dress blue cap was one that fit perfectly within my Navy collecting focus (see: Focused on Niche Areas of Collecting: USS Washington). The flat hat, a post-1933 design included a tally that indicated it was from the USS Seattle and yet there are a few questions regarding the hat design and tally combination. To help illustrate these questions, I have summarized the timeline of the ship below.

A flat hat from the USS Seattle, the former armored cruiser USS Washington, that dates from the interwar period of 1933-1940 (Source: eBay image).
USS Washington/USS Seattle Timeline
- 1906, August 7 – Commissioned USS Washington (ACR-11)
- 1916, November 9 – Renamed “Seattle”
- 1920, July 17 – Reclassified (CA-11)
- 1927, August 29 – Changed Status to Receiving Ship
- 1931, July 1 – Classification changed to “Unclassified”
- 1941, February 15 – Reclassified (IX-39)
- 1946, June 28 – Decommissioned from active service
- 1946, July 19 – Stricken from Naval Register
- 1946, December 3 – Sold and eventually scrapped

The tally of the USS Seattle flat hat shows some wear but is in good condition, overall (Source: eBay image).
USS Seattle’s reclassification from a combatant ship (a heavy cruiser) to a receiving ship transformed her role in regards to crew assignments. The mission of a receiving ship is two-fold: to serve as a location to receive newly inducted recruits as their personnel records are established, they are issued uniforms and initial training is conducted before they are sent on for to complete training and assignment to their permanent command. The other role of a receiving ship is to serve as a location for sailors who are nearing the end of their enlistments to be processed out of the naval service, having been transferred from their commands to await discharge. Receiving ships also served as locations for judicial proceedings such as courts martials. Sailors who were processing in would have most likely been issued dress blue caps with a generic “U.S. Navy” tally to be worn until they reached their permanent duty station. Depending upon the time that it takes to outprocess, sailors awaiting discharge would have worn the tally of their last command.

Stenciled to the back of the leather sweatband of the USS Seattle flat hat is the sailors name: Feldt (Source: eBay image).
In attempting to determine the age of the cap and tally, it could only be pinpointed a range of years between 1933 and 1940 due to the time-period for the pattern of the hat (1933-1963) and the elimination of ship names from cap tallies. With some researching of the sailor’s name (“FELDT”) stenciled to the backside of the leather sweatband, the date range could be narrowed down by searching the ship’s muster rolls. It is most-likely that Feldt was part of the crew of the Seattle responsible for the in and out processing of the transient sailors that were temporarily assigned to the ship.
On April 1, 1963, the Navy unceremoniously brought about the end of the the dress blue cap, having been relegated to an item that sailors stuffed into their seabags, seldom seeing wear since being issued at bootcamp. Since the World War II, the white hat (lovingly referred to as the “Dixie Cup”) was popularized due to its ease of wear and that it could be rolled up and stowed into the back of the trousers, concealed beneath the jumper when in doors and not in use. With the vast numbers of wartime films depicting sailors in their dress whites and blues wearing their white hats cocked forward, aft or to the side, rolled edges, or hand-formed to a number or shapes, the versatility of the white hat (worn with all of the enlisted uniforms while the flat hat was only worn with dress and undress blues) drove the dress blue cap out of use. So many of the caps were made during WWII that the Navy supply system was still issuing them into the early 1960s.

A Piece of the Day of Infamy or Simply a Connection to an Historic Ship?
For most Americans, this time of year spurs thoughts of lighted trees, large and rotund red-suited elves, massive crowds at local shops and mega malls, anxiety, and ever-increasing credit card debt in the rush to obtain the perfect gift for loved ones and friends. All of this translates into the hopes that the recipients of said gifts illuminate with unbridled joy and gratitude. Meanwhile, a continuously diminishing segment of the population, in addition to the aforementioned seasonal activities and concerns, recall a monumentally tragic and infuriating event, now 75 years hence.

The USS Arizona’s bow pitches upward on the high seas sometime in the late 1930s (source: U.S. Navy Naval History and Heritage Command).
At that time (three quarters of a century ago), Americans, like today, were in the throes of an economic depression while war and conflict littered regions around the globe. Many Americans had been without work for months, while others had been unemployed for years. The holiday season was in full swing but on an infinitely smaller scale. All of this about to change, catapulting the nation into chaos and doubt while transforming the nation’s doubt into a singular mindset, while rising from the literal ashes and wreckage to defeat fascism.

The World War II generation is departing our society at an increasingly accelerated pace. The men and women who banded together on the war front and home front still recall the Day of Infamy, remembering those who fell prey to unpreparedness and bumbling governmental bureaucracy and a dastardly attack. When the final tally was counted in the weeks and months following December 7, 1941, more than 2,400 Americans were dead at the hands of the Empire of Japan. Three battleships of the U.S. Navy were complete losses. One of those ships, the USS Arizona (BB-39), was obliterated by an aerial bomb that penetrated into the forward magazines (for the 14” guns), igniting a cataclysmic explosion, killing 1,117 sailors, accounting for more than half of the Pearl Harbor attack death toll.

The memorial structure straddles the stricken ship’s hull as she rests in the mud and silt of Pearl Harbor.
In the 75 years since that fateful day, much has transpired to cause the slow evaporation of Pearl Harbor memories of from the American conscience. The current younger generation experienced their own day of infamy 11 years ago with the 9/11 attacks, fueling the 12/7/41 forgetfulness with redirected angst.
Conversely for militaria collectors, the events of Pearl Harbor are held close to the vest and worn on their sleeves. The pursuit to hold a piece connected to that tragic day isn’t taken lightly. More often than not, collectors pay an extremely high premium for the honor of preserving and displaying items that tell the individual stories of the struggle to survive and the will to fight the attackers. Collectors treasure anything directly related to a veteran, aircraft or ship that participated in warding off the Japanese onslaught.

Inside the Arizona Memorial, this wall bears the names of the 1,177 victims who were killed on that tragic day.
For me, the realization of the Pearl Harbor collector mindset truly occurred for me awhile ago when I spotted an auction listing for a flat hat from a navy veteran that served aboard the most notable ship casualty of the attack, the Arizona. I scanned through the associated photographs, noting the condition while attempting to approximate the age of the item.

Worth its weight in gold, this flat hat recently sold for nearly $900 at auction (source: eBay image).
By 1941, operation security had been steadily increasing due to the waging war, both in Europe and the Western Pacific. The Navy, seeking to reduce the visible indications of ship movements, stipulated in uniform regulations that all ship identifiers, such as ship-name tallies on enlisted blue flat hats, be omitted from uniforms. Generic “U.S. Navy” lettered tallies replaced the those bearing the names of ships which meant that the one in the auction listing predated WWII by at least a year. However, this particular cap is a pre-1933 design that has had the stiffener removed leaving a more “slouched” appearance that became standard with the 1940s caps.
- Though the lettering is faded and shows some signs of the bullion thread corroding, this USS Arizona enlisted sailor’s flat hat is a rarity and is well worth the investment (source: eBay image).
- The real value of the USS Arizona flat hat is in the tally. Due to the historic-nature of the famous ship and the scarcity of tallies bearing ship names, the damage seen here had little impact on the final selling price of the hat (source: eBay image).
- Condition is everything. This hat has some serious issues from moth damage and was repaired at some point (source: eBay image).
- Top of the USS Arizona flat hat – showing the moth holes (source: eBay image).
- This view shows the inside of the Arizona hat and gives some indication to the age – the liner does appear to be post World War I (source: eBay image).
- Details of the flat hat – showing how the tally is tied into the traditional bow at the side of the hat (source: eBay image).
The condition of the hat left lots to be desired. From dozens of small holes scattered across all of the woolen surfaces, it was readily apparent that moths had a field day as they enjoyed their “hat salad.” The only components on this cap untouched by the Lepidoptera larvae were the tally and the liner.
What would be a significant value-increasing factor is if the hat bore the name of its owner. I was unable to discern from the provided photos any hint of a stenciled or inscribed name. If I had been able to see the original owner’s name, I might have been able to locate related details concerning his naval service, and quite possibly, the dates he served aboard the Arizona. It might be safe to assume that the value of the hat increases if the veteran did survive the ship’s sinking. However, based upon the features of the hat (the overall design, the liner and the tally), I would surmise that the hat is closer to the World War I-era.
Regardless of when the hat was used or if it belonged to a survivor of the Pearl Harbor attack, the auction’s final, closing bid of $848.00 was astonishing. Without a doubt, the winning bidder took a chance on acquiring an extremely rare piece with direct ties to a historic ship. In doing so, this collector now possesses a tangible connection to that fateful day.
