Another summer read mentioned on Talk of the Nation is the classic Sailing Alone Around the World by Joshua Slocum, originally published in 1899.
About the book:
In 1895, Slocum set sail in his sloop, the Spray, on a voyage that was to take 3 years & earn him a place in history as the first man to navigate the globe singlehandedly. Here is Slocum's own story, told with the salt resilience of an old sailor.
From the Joshua Slocum Society International:
Nova Scotia born, with family roots in New England, Captain Slocum commanded some of the finest tall ships that ever sailed the seas. On April 24, 1895, at the age of 51, he departed Boston in his tiny sloop Spray and sailed around the world single-handed, a passage of 46,000 miles, returning to Newport, Rhode Island on June 27, 1898. This historic achievement made him the patron saint of small-boat voyagers, navigators and adventurers all over the world.
