Dear Mr. Miller,
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 the USS USS Tolovana (AO-64) for 1965 through 1966. The deck logs you seek are closed for digitization. Please see the blog CLOSED - Vietnam War-era U.S. Navy & Coast Guard Deck Logs for Digitization Project for more information. National Archives staff are currently working to refile deck logs that have been digitized under this project. When these records are reopened, the staff will post a follow-up reply.
We regret any inconvenience this may cause you.
