There is a new book available that includes extensive coverage of the Coast Guard role in the Vietnam war. Best of all it is free and is available for download in pdf format. Just click on the link.
WAR IN THE SHALLOWS, U.S. NAVY COASTAL AND RIVERINE WARFARE IN
VIETNAM, 1965–1968
Yes, I know it says US Navy, but it does seem to give the Coast Guard its due, despite the title.
Thanks to Lee for bringing this to my attention.

Operation Market Time was in today’s terms a joint operation. USN DERs patrolled the outer layer along with USCGC, the middle layer was made up of USCG 87 ft cutters and older types; the inner layer was patrolled by USN Swift boats. RVN junks and boats were used too on the inner and middle layers and at the end the outer layer. Read more about it @ Warboats.org here:

“… the boat with the best combat record was the Coast Guard WPB, which was barely modified at all for use in Southeast Asia.” page 322.
