Book by James Wharram
A tale of adventure in the fifties, when James Wharram and two German girls, Ruth and Jutta, sailed from Falmouth in their homemade catamaran TANGAROA.
The story of their stormy crossing of the Bay of Biscay, their winter in northern Spain living off the proceeds of magazine articles, and the dangers encountered in their unusually rough trade wind passage to Trinidad.
In Trinidad, they first built a house raft out of bamboo and then built the 40ft catamaran Rongo, sailed her to New York and then across the North Atlantic back to Britain (the first catamaran successfully to do so). The book makes fascinating and compelling reading. A classic.
Soft cover, many photos.
