HistoryA character grade: shown, never part of Captain Cook’s overall grade.
Few Hawaii towns list much on the Register (a typical Hawaii town has 0.0 per 10,000 residents, the U.S. 2.4), so Captain Cook’s 8.8 sits above most of its state (88% of Hawaii towns have fewer) while its 3 historic buildings outnumber those of 65% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to B. The pre-1940 share is a Census survey estimate (±6.6 points). The founding year is the first post office, not a stated founding date.

What stands out about Captain Cook’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The area surrounding present‑day Captain Cook has been inhabited for centuries and includes several sites significant to Native Hawaiian history. In 1779, British explorer Captain James Cook made landfall at nearby Kealakekua Bay during his third Pacific voyage. Cook was killed there on February 14, 1779, following a conflict between his crew and local residents.
The modern community developed much later. In the early 20th century, the Captain Cook Coffee Company established a post office in the upland agricultural zone above the bay. Under postal naming conventions of the period, the post office name became the name of the surrounding settlement, and the community has been known as Captain Cook since that time.
The Captain Cook post office opened in 1924, the earliest record of the town by name (U.S. post office records).
