For her age group, the "Swallows and Amazons" series is probably as good a way of stimulating interest as any - it worked on me!
Tristan Jones books for enjoyment (dont make the mistake of believing they are anything more than loosely based on his adventures)
For the older children, Bernard Cornwell's sailing based books such as "Stormchild".
"Sell up and sail" for the late teen
Patrick O'Brian provides lots of sailing adventure, but probably appeals more to the adult reader.
