How do you know this? I have read that Children born aboard a ship in transit have their birth listed as having occurred *IN* Hawaii.
I think if a woman filled out (in 1961) an affidavit of at home birth, Hawaii would have accepted it and initiated all the appropriate paperwork. My recollection is that the mother had up to a year to bring the child in for verification.
Here's the general rule as it appears in a CDC report on how to complete a birth certificate in regards to place of birth:
If this birth occurred en route, that is, in a moving conveyance, enter the city, town, village, or location where the child was first removed from the conveyance.
If the birth occurred in international airspace or waters, enter ‘‘plane’’ or ‘‘boat.’’

If the birth occurred in international waters or airspace, enter the location where the infant was first removed from the boat or plane.
