1977 Nautor Swan 431

Wilmington, United States


The name Nautor Swan has long been associated with quality and craftsmanship and epitomizes the essence of a pure sailing vessel.  Its classic lines and beautiful profile are only surpassed by its sea-worthiness, solid construction and impeccable track record, making this Swan, both a comfortable cruiser, as well as a very competent racer.

This beautiful Sparkman & Stephens designed hull is #18 of only 32 made, and is arguably one of the nicest hulls around with a rather roomy interior and user friendly layout.
