COLREGS Quiz

Which of the following best describes the primary intent of Rule 1 in the International Regulations for Preventing Collisions at Sea (COLREGS)?

• To establish national regulations for each country

• To create a uniform navigational environment

• To provide guidelines only for large vessels

• To allow vessels to navigate freely without rules

Which scenario illustrates the importance of Rule 1 in preventing collisions at sea?

• A small boat exempted from following any navigational rules

• A vessel disregarding Rule 1 due to clear weather conditions

• A vessel choosing to follow only national regulations in international waters

• Two vessels from different countries following the same international standards in a busy sea lane

In the context of Rule 1, what is the role of technological systems like AIS and ECDIS in navigational safety?

• They ensure absolute accuracy in all navigational decisions

• They have no impact on Rule 1 application

• They can lead to over-reliance on technology, complicating Rule 1 application

• They replace the need for human navigational skills

Rule 2 of COLREGS emphasizes that the rules must be strictly followed unless:

• The vessel is operating in inland waters.

• Departure is necessary to avoid immediate danger and aligns with good seamanship.

• The vessel is a fishing boat engaged in trawling.

• The Master receives permission from coastal authorities.

In which scenario would a departure from COLREGS likely be justified?

• A cargo ship ignores navigation lights to save fuel.

• A tanker abruptly changes course in clear weather to test emergency drills.

• A yacht fails to maintain the lookout to allow the crew extra rest.

• A vessel in fog steers into a traffic separation scheme (TSS) to avoid a collision with a drifting wreck.

When departing from COLREGS to avoid danger, a vessel must ensure its actions:

• Are approved by the company’s Designated Person Ashore (DPA).

• Prioritize the vessel’s commercial schedule.

• Comply with the ordinary practice of seamen (e.g., sound signals, maximizing visibility).

• Follow the nearest coastal state’s local rules.

According to Rule 3(a), which of the following is not considered a "vessel"?

• A hovercraft operating in displacement mode.

• A seaplane taxiing on water.

• A fixed oil drilling platform.

• A Wing-In-Ground (WIG) craft.

A sailing yacht temporarily using its engine is classified as:

• A sailing vessel.

• A power-driven vessel.

• A vessel restricted in ability to maneuver.

• A vessel not under command.

Which vessel qualifies as "engaged in fishing" under COLREGs?

• A trawler dragging a net.

• A yacht trolling a single fishing line.

• A cargo ship transporting frozen fish.

• A pilot boat with fishing gear stowed.

A vessel is "not under command" (NUC) when:

• It is anchored in a busy channel.

• Its engine fails in heavy traffic.

• It is towing another vessel.

• It is fishing with nets.
