BOTH INTERNATIONAL & INLAND An anchor ball need NOT be exhibited by an anchored vessel if she is __________.

🔍 Key Concepts

• Rule 30 – Anchored Vessels and Vessels Aground in the Navigation Rules (day shapes and when they are required) • The difference between length of vessel and location (busy traffic area vs. out of the way) for day shapes • Special exemptions for very small vessels at anchor

💭 Think About

• Look at which answer choice talks about BOTH the vessel’s size AND where it is anchored, and compare that to the wording in Rule 30. • Ask yourself: When is an anchored vessel most likely to be a collision risk and therefore really NEED to show an anchor ball? When is that risk low enough that the rules give an exemption? • Eliminate any options that sound like general convenience (e.g., common practice) rather than a specific, narrow exemption in the rules.

✅ Before You Answer

• Verify the exact length in meters below which the exemption applies in Rule 30 (is it 7m, 50m, or 150m?). • Check whether the rule mentions being in or near a narrow channel, fairway, anchorage, or area where other vessels normally navigate as part of the exemption conditions. • Confirm that the exemption refers specifically to NOT having to show the anchor ball day shape, not to lights, sailing rigs, or other conditions.
