The boats were fitted with either Ford or Perkins diesels. One of several models sold based on this particular hull.
This note from Mayflower owner, Richard Johnson:
"42 hulls were built by May flower Yachts in Taiwan between 1980 and 1984. It took 7 months to build each yacht"....., "Most of the yachts were semi custom two or three cabin versions. George Stadel III supervised all construction to a very high standard. George Lim was the yard manager."
A shallow draft version was offered.
