🔍 Key Concepts

• Inland Rules – Maneuvering and Warning Signals (33 CFR Part 83, Subpart C) • Difference between prolonged blast and short blasts in sound signals • Special Inland-only signal for a vessel leaving a dock or berth vs other situations (anchored, backing, overtaking)

💭 Think About

• First, recall which maneuver (overtaking, leaving dock, backing, or being at anchor) uses only a prolonged blast under the Inland Rules, without any short blasts added. • Think about what signals are normally used for backing (engines astern) and overtaking – how many blasts, and are they short or prolonged? • Consider what sound, if any, a vessel at anchor in clear visibility would normally make in a busy harbor under Inland Rules.

✅ Before You Answer

• Verify in the Inland sound signal rules which situation uses one prolonged blast as a stand‑alone maneuvering signal in clear visibility. • Confirm that backing and overtaking signals involve short blasts rather than a single prolonged blast. • Check that a vessel getting underway from a dock or berth has a specific Inland-only sound signal and compare its description to the question’s wording.
