70% to pass

Your vessel is participating in the Voluntary Observing Ship Program, you are preparing WS Form B-80 as seen in illustration D041NG below. One-half of the sky is covered with clouds, and the anemometer indicates that the apparent wind is from 340° relative at 14 knots. You are on course 307°T at 12.6 knots. How should you encode group Nddff?

Diagram for USCG Navigation General: Your vessel is participating in the Voluntary Observing Ship Program, you are...
A 43013
B 53414
C 54013
D 42205
AI Explanation

The correct answer is D) 42205. To encode the group Nddff, we need to consider the following information: - One-half of the sky is covered with clouds, which corresponds to cloud cover code N = 4. - The apparent wind is from 340° relative at 14 knots. Translating this to the ddff format, we get dd = 34 (340°) and ff = 14 (14 knots). The other options are incorrect because: A) 43013 does not match the given wind direction and speed. B) 53414 does not match the given cloud cover. C) 54013 does not match the given wind direction and speed.
