Knysna – 500SE

Florida, United States

PRIVATE ISLAND is a beautiful condition Knysna 500SE blue voyaging catamaran with the desirable 3-Cabin Owner’s Version layout.  She has been totally dialed-in over several thousand cruising miles and is ready for her next adventure. She is extensively equipped with everything you could want to make liveaboard and passage making as simple as possible.  She is uniquely well equipped to be operated shorthanded.  Several key features include:

–       ICW-Friendly Rig (63ft air draft)

–       LeisureFurl In-Boom Furling Mainsail

–       Profurl Electric Furling Headsail

–       Hydraulic Tender lift / Swim platform

–       1280ah Lithium (LiFePO4) House Battery Bank

The Knysna 500SE represents a wonderful option for the cruising couple or family who’s hoping to find a high-quality catamaran that has more character and better sailing performance than the average charter-oriented production boat.  Knysna Yachts is a boutique, semi-custom builder located in the stunning seaside community of Knysna, South Africa.  Their catamarans are built to withstand the turbulent waters of the South Atlantic and Indian Oceans.  Most Knysna Yachts begin their life with a 5000nm crossing of the Atlantic from South Africa to the Caribbean.  The track record of ocean crossings is a testament to the quality of their construction.  Furthermore, because these boats are built exclusively for private ownership on a semi-custom basis, the fit and finish of the interior is on par with any of the finest yacht brands in the industry.  Private Island is no exception with her sophisticated interior and upgraded systems.  You really have to see her in person to fully appreciate the quality and care that went into her design and build.

See below in the listing for a comprehensive list of Private Island’s equipment and upgrades.  She is fully serviced and ready to go having just come off her annual yard period.

Private Island is US DUTY PAID.  She is available for showings by appointment in sunny St Augustine, FL.
