1977 Gulfstar 50 ketch “Calypso”

$159,000 Price Reduced $149,000!

Location: Portsmouth, New Hampshire


The Gulfstar 50 is the best looking of the well regarded Gulfstar line. With her split rig and generous displacement, she is a blue water cruiser easily handled by a couple and sails comfortably in all wind and sea. Calypso was completely re-fit in 2008 by a Maine master builder with ongoing upgrades by knowledgeable owners to produce a premier Gulfstar 50. All details of the refit process are shown below, with photos on request. This vessel is a remarkable value and serious Gulfstar 50 buyers should look at this one last. Throw your personal gear on, provision and go. The current owners have sailed her 12,000 miles in the last ten years, from the craggy shores of Canada to the sublime waters of the Caribbean and the Bahamas.
