The Thai Jack is composed of a flag of the national colors defaced by the naval badge in gold. This badge is composed of an anchor with a rope/chain upon which is imposed a version of the chakra symbol. Note the use of the chakra on the flag of India. All of which is surmounted by the royal crown of Thailand. Sources: Flaggenbuch 1939, Barraclough 1969/1981 and others.

From the Singha Beer source:

Chan Flag (B.E.2460) [1917 AD]
This flag is similar to the "Trairanga", except for an anchor – threaded through a chakkra, which occupies the center, beneath [a] yellow crown. [Identical to the Jack 1917 (th-n-jak.gif) above, but with clockwise Chakra instead of a counterclockwise one.]

In B.E.2460 [1917 AD] King Rama VI changed old "Chan" flag into the version seen above. The flag is flown from the foremast of the Royal Yacht on a special mission, whether it be a passenger ship or a battleship. It can be flown from the bow whenever the ship stands guard over the harbour. Later, according to a Royal Decree issued in B.E.2479 [1936 AD], it could also be flown from the stem [sic – possibly "stern"?] of any ship in the Navy, denoting that a court martial was taking place on board.

In Flaggenbuch 1939 this appears with the caption "Gößch der Kriegschiffe; an der Fockmastraa: Wachschiff in Hafen; an der Gaffel: Marinekriegsgericht. Dienstflagge der Marinegebäude", that is "Warships' jack; on the foremast: harbour's guard ship; on the gaff: naval court martial. Service Flag on Navy Buildings", all of which fits well with the above reference.
