🔍 Key Concepts

• Difference between planning publications and enroute publications • What type of book is used for broad ocean passage planning versus coastal/detail sailing • Which publication focuses on ports and facilities rather than routes

💭 Think About

• Ask yourself: which option is designed to help you choose and compare ocean passage routes before the trip, not while you are already along the coast? • Consider whether a voyage from San Francisco to Japan is mainly an ocean passage problem or a coastal navigation problem. • Look at which titles sound like they cover local details (coastlines, harbors) versus large-scale, across‑ocean route guidance.

✅ Before You Answer

• Identify which choice is specifically labeled or known as a planning reference for long‑distance voyages. • Eliminate any publications that mainly describe coastal features, harbor information, and local regulations. • Check which book is primarily a port directory (names, positions, facilities) rather than a route‑planning guide.
