Major Price Reduction-This is one incredible value for a boat that's all set up to go anywhere in the world!


Built for the rugged waters off California, this beautiful blue-water boat is ready for her next adventure! Kognita just sailed 8,400 miles from California through the Panama Canal to Rhode Island. No one ever believes she was built in 1973, she is a true modern classic! Lots of light, very spacious, and a beast in the ocean. She tracks well sailing thanks to her 3/4 length cutaway keel and attached rudder. Completely set-up for short-handed world-cruising, she holds 110-gallons of fuel, 80-gallons of water, has 370-watt solar panel and a 900-amp hour gel battery bank, and a Monitor wind-vane. Shes solid, well-equipped, and gorgeous.

In 2017, Kognita underwent a 3-year professional refit including new awl-grip paint on decks, hull and mast, new North sails, new wire standing rigging, new rudder, fully re-wired, fully re-plumbed, new removable headliners with recessed lighting, new layer of epoxied fiberglass over the entire hull with 5 layers of epoxy barrier coat, new roller fuller staysail with self-tacking track and lots more!

Shes currently in Wood's Hole, Massachusetts and is ready to set sail to the Caribbean and beyond! She is already measured/registered with the Panama Canal Authority and would be excited to make it to the South Pacific (that's what her original plan was, damn covid!).
