ALCOA PIONEER position 10 March 1942?

Calling on the might of this forum to try establishing the whereabouts of ALCOA PIONEER on or around 10 March 1942.

In more detail; was the ALCOA PIONEER in port of Castries on St Lucia at the same time as U-161 of Achilles torpedoed the RMS LADY NELSON and SS UMTATA?

Attached (below) is the voyage log book of the PIONEER, highlighted are her recorded departures from:

• New York, February 21st
• Port-of-Spain, March 20th

The dates above are the “Date of sailing” dates meaning that the PIONEER could have arrived Port-of-Spain earlier.
I am quite certain that she sailed independently from NY i.e. not in a convoy.

As a bonus question: what was her cargo?

Any and all help is appreciated.

I have checked MARAD already - no clues given. (ALCOA PIONEER)

 

"These pre-1967 records, from Record Group 26, Records of the U.S. Coast Guard, Merchant Marine Personnel and Licensing Records, contain a wealth of information. Most notably they contain rich genealogical history, photographs, and artifacts such as ID cards or log books that relay information from their journey over the seas."

Hmm, thanks - this appear to be geared more towards Marine Personnel rather than tabular movements of a ship. One could potentially draw conclusions from mariners mustering on and of a ship, like the Muster Rolls of a Navy ship...

Also seems that none of this is digitised, I would not even know where to start

 

All I need is the one, crucial, breadcrumb..

I've also come to realise that in this period of February 1942 the Sea Frontiers were established moving from the previous "Naval Costal Frontiers". Result being that the reporting into EASTSEAFRON, GULFSEAFRON, CARIBSEAFRON etc were quite limited. Point being; there are very little ship and convoy movements reported...

Hmm, wonder if I can find the ship in a Naval District report... be back soon ok thx bye
