The earliest version of the MARINER 40 was built of wood in 1965 and then later in fiberglass with wood decks and superstructure. Far East Yachts built the boats, first in Japan (95 hulls) and then in California. Later the molds for the MARINER 40 and MARINER 36 were purchased by another company and construction continued for some years at the Ta-Yang yard in Taiwan.
