As for going "out there" without a clear destination, I sort of do get that. I can see that meeting the challenge of small boat sailing out in the big wild sea is a challenge in its own right.
On a slightly different note, I felt that by book three Roger was struggling to find too much to say and while it was still a good book, you can almost hear him looking for the "next thing" to do. I almost woried that he was in danger pf painting him into an image that people (publisher etc) would expect him to follow because it is commercially successful. It was nice to hear that he is fitting out a new boat for a different kind of adventure.
