From what I hear there are not so many places to anchor in the Hawaiian Islands. That is, places are "few and FAR between." Could be the "any port in a storm" refuge at work, etc. There is a harbor (Kukuiula) on the south coast of the island but @ 30 n.mi. distant from the one they are in now; so, I don't know. They appear to be in the most protected area of the mooring field if you examine a chart of the bay.
