🔍 Key Concepts

• Course recorder purpose and what each pen records (course pen vs. zone pen vs. thermograph pens) • How chart paper must be positioned so that recorded information is meaningful • Difference between time, position, and heading/course information on a chart recorder

💭 Think About

• Ask yourself: when you first load new chart paper, what must be aligned so that the recorded track (course information) corresponds correctly to the scale printed on the paper? • Which of the options deals with heading/course alignment rather than temperature, time zone, or paper end position? • Think about which adjustment directly affects how the vessel’s heading will be drawn on the new sheet so it can be read accurately later.

✅ Before You Answer

• Identify which pens are actually thermograph pens and what they measure, versus the pen that records course/heading. • Check which control on the recorder sets the reference line or zero point for the ship’s heading trace. • Verify which option refers to aligning the recording pen with the printed scale on the chart paper, not just moving it to the side or setting a time reference.
