The ship's record is not your service record
This entry describes the ship, not any individual sailor: was the veteran aboard during the listed activity is a question only service records answer. A ship appearing here does not by itself prove any person was aboard on the listed dates, and the categories that involve going ashore pair with the veteran's own statement of having done so.
The wider eligibility rules
The law grew past this list
Under the Blue Water Navy Vietnam Veterans Act, federal law presumes herbicide exposure for veterans who served on a vessel "not more than 12 nautical miles seaward" of the demarcation line of the waters of Vietnam and Cambodia between January 9, 1962 and May 7, 1975 (38 U.S.C. 1116A). That offshore presumption does not depend on this list. The regulation text of 38 CFR 3.307 still reads the older way; the statute controls.
This list matters today mainly as evidence: it documents, in VA's own words, what this ship did and when.
