These laws were adopted because so many people were born on ships in transit to Hawaii, and so they wrote the law to allow them to claim the first Hawaiian port they came to as their place of birth.
And these laws have always been in place, and are still in place. This is not a 1982 thing, this is a before Hawaii even became a state thing.
I don’t find any record of that online. If you have, produce it. Shipboard births, if they were registered at all would have “AT SEA” on the birth certificate, not the name of a hospital, and presumably a ship’s doctor would have signed them.
