While some suggest that the combination of the overloaded condition, engine trouble, and bad weather may have conspired to sink ''Cyclops,'' an extensive naval investigation concluded: "Many theories have been advanced, but none that satisfactorily accounts for her disappearance."

This was observed definitively on , and is believed to have contributed to the sinking of another similar freighter, ''Chuky,'' which snapped in two in calm seas. Moreover, ''Cyclops'' may have hit a storm with winds. These would have resulted in waves just far enough apart to leave the bow and stern supported on the peaks of successive waves, but with the middle unsupported, resulting in extra strain on the already weakened central area.

) from the Far East to San Francisco. The crews of these ships reported that Worley suffered from a personality allegedly akin to that sometimes ascribed to HMS ''Pandora'''s captain Edward Edwards, with the crew often being brutalized by Worley for trivial things. Worley was commissioned as a lieutenant commander in the Naval Auxiliary Reserve on 21 February 1917.
Naval investigators discovered information from former crew members about Worley's habits. He would berate and curse officers and men for minor offenses, sometimes getting violent; at one point, he had allegedly chased an ensign about the ship with a pistol. Saner times found him making his rounds about the ship dressed in long underwear and a derby hat. Worley sometimes would have an inexperienced officer take charge of loading cargo onto the ship while a more experienced man was confined to quarters. In Rio de Janeiro, one such man was assigned to oversee the loading of manganese

, something a collier was not used to carrying, and in this instance the ship may have been overloaded, which may have contributed to her sinking. The most serious accusation against Worley was that he was pro-German in wartime and may have colluded with the enemy; indeed, his closest friends and associates were either German or Americans of German descent. "Many Germanic names appear," Livingston stated, speculating that the ship had many German sympathizers on board. One of the passengers on the final voyage was Alfred Louis Moreau Gottschalk, the consul-general in Rio de Janeiro, who was as roundly hated for his pro-German sympathies, as was Worley. Livingston stated he believed Gottschalk may have been directly involved in collaborating with Worley on handing the ship over to the Germans. After World War I, German records were checked to ascertain the fate of ''Cyclops'', whether by Worley's hand or by submarine attack. Nothing was found.
Near the time the search for ''Cyclops'' was called off, a telegram was received by the State Department from Charles Ludlow Livingston, the U.S. consul on Barbados:
:''Secretary of State''
:''Washington, D.C.''
:'' 17,, 2 April p.m.''
:''Department's 15th. Confidential. Master CYCLOPS stated that required six hundred tons coal having sufficient on board to reach Bermuda. Engines very poor condition. Not sufficient funds and therefore requested payment by me. Unusually reticent. I have ascertained he took here ton fresh meat, ton flour, thousand pounds vegetables, paying therefore 775 dollars. From different sources gather the following: he had plenty of coal, alleged inferior, took coal to mix, probably had more than fifteen hundred tons. Master alluded to by others as damned Dutchman, apparently disliked by other officers. Rumored disturbances en route hither, men confined and one executed; also had some prisoners from the fleet in Brazilian waters, one life sentence. United States Consul-General Gottschalk passenger, 231 crew exclusive of officers and passengers. Have names of crew but not of all the officers and passengers. Many Germanic names appear. Number telegraphic or wireless messages addressed to master or in care of ship were delivered at this port. All telegrams for Barbados on file head office St. Thomas. I have to suggest scrutiny there. While not having any definite grounds I fear fate worse than sinking though possibly based on instinctive dislike felt towards master.''
:''LIVINGSTON, CONSUL''.
Some reports attribute the telegram to Brockholst Livingston, but he was actually the 13-year-old son of the consul.
Sister ships
''Cyclops'' had three sister ships, all commissioned in 1913, which were all ill-fated.

''Langley'' was the first American aircraft carrier and was vital in developing United States naval aviation capabilities. She was converted again between 1936 and 1937 as a seaplane tender and redesignated as AV-3. She was stationed in the Philippines in December 1941 and departed for Australia following the Japanese attacks on Pearl Harbor and the Philippines. On 27 February 1942, while ferrying fighter planes to Southeast Asia, she was attacked by Japanese aircraft and was hit by five bombs, causing critical damage. After her surviving crew members were rescued, ''Langley'' was scuttled by torpedoes fired by her escorting destroyers.

The USS ''Cyclops'' is encountered in the first episode of the 2005 television miniseries, '' The Triangle''. In the story, a team of four experts is assembled by a shipping magnate to investigate the mysterious disappearance of some of his vessels. The team discovers the sunken wreck of the ''Cyclops'' whilst conducting research in the Bermuda Triangle aboard a submarine.
A ship implied to be the USS ''Cyclops'' also appeared in the 2006 animated movie '' Scooby-Doo! Pirates Ahoy!'' It was shown in a scene where the main protagonists are about to enter the heart of the Bermuda Triangle, so the movie seems to suggest that the disappearance of the ship is linked to the mystical, supernatural powers and the legends of the Bermuda Triangle. As it passes by the ship carrying the protagonists, it is confirmed by Velma to be the ''Cyclops''.
