The terminology around what defines a “superyacht”, “megayacht” and a “yacht” is not set in stone, with often different interpretations. Generally speaking, the term “yacht” encompasses every size of vessel, both motor and sail. A superyacht is considered a pleasure yacht with a load line length of 24 meters and over (though some argue that a true superyacht is 30 meters and over). A megayacht is American terminology, and often refers to yachts over 60 meters in length.
