My wife and I are the ideal audience for a book such as this - we are planning to do just what the title says: Sell up and sail.
We both found the writing to be witty and entertaining and certainly learned a good deal from the book. We both felt that the chapters written by Bill were excellent: the work of an experienced, knowledgeable and sensible man.
Unfortunately, we also agreed that the chapters written by Laurel were, at best, space fillers. We also had some trouble taking a lot of her 'advice' seriously. Certainly, to suggest that SEVEN saucepans are a minimum requirement onboard a sailing yacht seems nonsense: we have enjoyed many years of married life (with 3 children) and cannot ever remember needing (or even owning) seven saucepans.
Having said that, we believe that the book is worth the price: for Bill's input alone, and would recommend it to the discerning reader who is able to differentiate between the logic written by Bill and the more unrealistic 'advice' often offered by Laurel.
