In "Folklore and the Sea" (1973, pp. 155-56), Horace P. Beck prints a version of "Rosabella" that he collected in the West Indies (he doesn't say where or when). The melody resembles the familiar one.

There are essentially only two stanzas, but they are repeated somewhat randomly to make the performance seven stanzas long. The spoken bits seem to be an occasional feature of West Indian singing:

Come let me join Rosabella. "Heave away" - (spoken)
Come let me join Rosabella. "Heave away" - (spoken)
Come let us join, Come let us join,
The saucy Rosabella. "Heave away." (spoken)

Contractor beat the Orinaca, "Heave away" (spoken)
The Orinaca beat the Contractor, "Heave away." (spoken)
He beat her once, he beat her twice
He beat her right down the Orinoco. "Heave away" (spoken)

These are basically the stanzas that J.S. Scott sang for Carpenter in the '20s, though the names are apparently different and the "Boston Times" is gone (if it was there to begin with). I say "apparently" and "if" because of the poor audibility of the dictaphone recording.
