Just acquired a 1969 Michael Dufour designed Lestratte (spelling????) made in France in 1969. Acquired a "bargain boat" that appears solid, but haven''t yet hauled it out for exam. Was dismayed to learn, however, that it has a cast-iron bulb keel. Had hoped to use boat for some offshore cruising to Bahamas, Bermuda, etc. Any owners out there with any info on this boat????? Please help.
