First the yachts:
An L. Francis Herreshoff Reader, by L. Francis A. Herreshoff (HC, 1978, $8, which is 1/3 the internet price)
Herreshoff is legendary for his yacht designs. He is also known for his nautical articles. His book, Writings, is reprinted here, but so are articles never published in his other books. He writes on marine art, on the history of yachting, of old sea tales, and so much more.
Then the Tall Ships:
The Romance of Tall Ships, by Jonathan Eastland (Oversize HC, 1990, $2.50) -- SOLD --
Tall ships-their history, their rigging, their decorations, and what the newest ships look like now. Read it here. Also included is a 4 page glossary for those of us who do not sail. (I knew what aloft was, but not aback, abaft, or abeam.)
The Tall Ships: A Sailing Celebration, by Hyla M. Clark (Oversize HC, 1976, $2)
Operation Sail, July 4th, 1976:
16 Tall Ships, 50 medium sized tall ships, as well as more than 100 smaller sailing vessels, classic yachts and other historic craft- they all came to New York City's Hudson River to join in America's Birthday Party. (And for more than 4 months it all was kept a secret from the public!)
These books are on the new non-fiction table.
