In one of his early books, Bill Mason recommended a tether system like what you describe, but some years later he changed his mind, and if I remember correctly, he came to the conclusion that tying packs securely in the boat was a better method. He wrote about changing his method in a later book. Since a lot of people go by what he wrote, even a recent book might recommend the same as what's in an early book by Mason.
