You are on a small sailing vessel approaching a larger commercial vessel that is constrained to a narrow, dredged channel. Even though you may have right of way under the basic sailing-vessel rules, what practical consideration should guide your actions?

A. The sailing vessel should anchor in the channel and wait for the commercial vessel to pass

B. Right of way is absolute — the commercial vessel must always give way to a sailing vessel regardless of the channel

C. Rule 9(b) states that a sailing vessel (along with vessels less than 20m) shall not impede the passage of a vessel which can safely navigate only within a narrow channel or fairway — even where the general sailing-vessel rules might otherwise suggest right of way, the practical reality of the larger vessel's confinement to the channel means the small craft should keep clear and avoid creating a close-quarters situation

D. This situation is not addressed by the COLREGS in any way

A. Neither vessel needs to act; both should maintain course

B. The vessel on the port tack shall keep out of the way of the other

C. Whichever vessel is larger must keep out of the way

D. The vessel on the starboard tack shall always keep out of the way

A. She must always show the full anchor light and ball regardless of location or size

B. Anchor lights are only required for vessels over 50 metres

C. A vessel of less than 7 metres in length, when at anchor in such a location, shall not be required to exhibit the lights or shapes (anchor light/ball) otherwise required by Rule 30 — this is a specific small-vessel exemption tied to both her size and the nature of the location

D. She must instead display the not-under-command lights
