"In his book, Choice Yacht Designs, Richard Henderson credits the inspiration of the Block Island 40 to the Sparkman & Stephens-designed Finnisterre, a centerboard yawl that won the Bermuda Race three consecutive times. That boat led to the production model Nevins 40, and later to several similar boats by other designers. The Block Island 40 and Hinckley Bermuda 40, both drawn by William H. Tripp, Jr., are the best known. All of these classic designs are stunningly beautiful examples of the now bygone era of proper sailing yachts. They are incredibly sea kindly vessels with the visual elegance and grace of mythical goddesses.Manitou was built by Migrator Yachts, the most recent of the respected builders of the Block Island." 40. Manitou has been very well maintained and excellent example of classic boatbuilding. 

A change in the owner's plans has made this fine yacht available. The bottom was repainted in September 2021 and the maxprop prop coated with propspeed. Manitou was sailed in the Chesapeake Bay until being sold and shipped to the West Coast in 2017.

The electronics have been upgraded with Raymarine hybrid touch digital Radar/Chartplotter, A new I70 repeated for wind/depth and speed has been installed, and AIS integrates into the system via the VHF radio.

Manitou also features reverse cycle airconditioning for comfort at the dock. a
