The famed Jamestown Boat Yard, in the summer of 2015, has worked its magic, as they have with so many Swans in their past, by completing a cosmetic refit and more. The teak decks and engine have been replaced in the past along with the upholstery. SAGACIOUS is showing "oh so fine" at this time. Inspections are highly recommended, you will not be disappointed!
