More info.
As you probably know there is a forum here dedicated to "Cherubinis". John Cherubini was the naval architect for the early hunters, around 1976 through 1984. That would cover the H27, H30, H33, H36, and H37C(mine). I am somewhat confused about the H25. It looks like a Cherubini but might have preceded his employment. John Jr. is still a regular contributor here on HOW. He worked closely with Dad, mainly interior design.
