What is the book?

Question

I recently saw a book that seemed intreguing, but can't remember the title. I think it was about a father and a daughter who go sailing. They are doing something that has gone on for generations of the family(not sure what it is but they are doing it). They come across something I think and it's set on one of the Great Lakes I believe. Does anybody know what this book is?

Answer 1

Lake Savana
