"The Boy, Me, and the Cat" by Henry Plummer.
If you boys like guns
and shootin' stuff this is the book for you.
They take their gaff rigged 20 odd foot sailboat from Falmouth, MA to Florida
and shoot all the game
they want around the 1920's along the coast. More a narrative then a novel but quite interesting none the less.
The cat does make it to Miami
though and the man and boy return to New England
in the end. An interesting look at life nearly 100 years ago along the eastern seaboard which is now home to the ICW
