Diagram for question 730
AI Explanation
The correct answer is C) 83322. To encode group Nddff, we need to follow the rules for the Voluntary Observing Ship Program and the WS Form B-80. For the given information: - The apparent wind is from 144° relative at 8 knots. - The vessel is on course 162°T at 15 knots. The correct encoding for Nddff is 83322, where: - N = 8 (wind direction from 144° relative) - dd = 33 (wind direction 144°) - ff = 22 (wind speed 8 knots) The other options are incorrect because they do not properly encode the given wind direction and speed information.
