Dear Mr. Delfaut,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Vessel Logs and Logbooks, 1971 - 1998 in the Records of the U.S. Coast Guard (Record Group 26) but were unable to locate any records of the USCGC Acushnet (WMEC-167) for 1989. These records may still be in the custody of the Coast Guard. For information about U.S. Coast Guard logbooks or other records that remain in the custody of the Coast Guard, please contact the Coast Guard FOIA officer by mail or fax at United States Coast Guard, Attn: FOIA Officer (G-SII). 2100 2nd Street SW, Washington, DC 20593. The fax number is (202) 267-4814.
We hope this is helpful.
