Question 1 of 2921866636ee928f7522a1c51a621

Your vessel is participating in the Voluntary Observing Ship Program, you are preparing WS Form B-80 as seen in illustration D041NG below. You are hove to in a hurricane on a heading of 328°T. The wind is from 030° true at 119 knots. How should this be encoded on the weather report form?

🔍 Key Concepts

• True wind direction in ship synoptic code is always the direction the wind is coming FROM, reported to the nearest 10°, and encoded as a two‑ or three‑digit number divided by 10. • In the Voluntary Observing Ship (VOS) code, very high wind speeds (near or above hurricane force) have special encodings; speeds over a certain limit are not written directly but use a ‘99’ or similar code plus an extra indicator. • The ship’s heading or hove‑to condition does NOT change how you encode wind direction; you still use the actual true wind direction, not relative wind or ship’s heading.

💭 Think About

• From 030° true, what tens‑of‑degrees value would you report for the wind direction, and how is that normally written in the VOS wind group? • At 119 knots, is the wind speed within the normal two‑digit range, or does it require the special high‑wind (hurricane) code? How does that affect the last two digits of the group? • Compare the answer choices: which ones treat the direction part consistently with 030°T, and which ones show the pattern used for hurricane‑force winds in the VOS code book?

✅ Before You Answer

• Be sure you are using true wind direction, not ship’s heading when deciding the direction digits. • Confirm from your VOS coding references how winds ≥100 knots are encoded (look specifically for a rule using 99 for the speed). • Verify that the first digit in the 8xxxx group correctly represents the type of wind observation (e.g., anemometer vs. estimated) according to the code form you’ve studied.
