Dear Mr. McGettigan,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Logbooks of U.S. Navy Ships and Stations, 1941 - 1983 in the Records of the Bureau of Naval Personnel (Record Group 24) that include the deck logs of PCE-843 from its commissioning on 3 February 1944 through its first decommissioning on 14 February 1947, and from 1 October 1950 through 12 August 1955 when it was placed out of commission in reserve status for the final time. For access to and/or copies of these logs, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
The reason that the USS Skowhegan can not be found on the second list you linked is because that list only includes logs of named ships. According to the US Navy’s Dictionary of American Naval Fighting Ships, the Skowhegan did not officially receive that name until after it had been placed out of commission. As the Navy did not created deck logs for decommissioned ships, even those in reserve status, we have no deck logs under that name.
We hope this information is helpful. Best of luck with your research!
