🔍 Key Concepts

• Purpose of each publication listed in the choices • Which publications are primarily for aids to navigation and lights vs. coastal/sailing directions vs. weather/ice information • Geographic focus of publications that specifically cover the Great Lakes

💭 Think About

• For each choice, ask: Is this mainly a navigation-aids book, a coastal pilot/coast description, or a weather/ice/forecast product? • Which of these is traditionally used by mariners to get detailed regional info (including seasonal conditions like ice) for the Great Lakes? • Does the title suggest a regularly updated log, a forecast/outlook product, or a sailing directions/coast description reference?

✅ Before You Answer

• Check which publication specifically covers the Great Lakes region in its normal scope • Verify which publication type is known for including seasonal hazards and ice information in addition to port entries and coastal descriptions • Be sure not to confuse a light list (aids to navigation) with a coast pilot (supplemental navigation information, local conditions, and hazards)
