Daniel Robb’s roots are in a once-prosperous Cape Cod family. He still lives there, in Woods Hole, but is a writer and carpenter of modest means. The only tangible remainder of the past still in family hands is a 68-year-old 15.5 foot Herreshoff sloop. The restoration of that boat is the subject of “Sloop”. It’s a good “project book” full of local characters and interesting digressions. Robb is a practical craftsman, not a perfectionist, and while there is an undercurrent of ill ease about the way the rich have come to dominate his home town the book is not overly sentimental.
