I own both. The "Practical and Technical Cruising Manual" is aimed at the prospective cruiser. It explains how to select and equip a yacht for cruising, and how to navigate it.
The chapters are:
Part one: the boat
Chapter 1. a boat for cruising
Chapter 2. on
deck
Chapter 3. cruising accommodations
Chapter 4.
electrical systems
Chapter 5. the rest of the systems
Chapter 6. acquisition strategies
Part two: cruising skills
Chapter 7. boat handling under power and sail
Chapter 8. piloting,
navigation, and the rules of the road
Chapter 9.
anchoring, running aground, and kedging off
Chapter 10. the ditty bag
Chapter 11.
weather predictions and heavy
weather sailing
Chapter 12.
extended cruising and staying in touch
I found it interesting but aimed at the affluent (not 500$/month) cruiser.
