What should a vessel directed by the Rules to keep out of the way of another vessel avoid doing?

A vessel that is directed by the Rules to keep out of the way of another vessel is required to avoid crossing ahead of that other vessel. This is crucial because crossing ahead could create a situation where a collision is likely, especially if the vessels are on converging paths. The vessel that must keep out of the way must demonstrate clear navigation and make movements that ensure it does not impede the safe passage of the other vessel.

In navigating, particularly in situations involving a power-driven vessel and a sailing vessel or two vessels of different types, understanding right-of-way rules is essential. When a vessel alters its course by crossing in front, it can lead to misunderstandings and reactions that increase the risk of an accident. Thus, keeping clear and maintaining a safe distance is vital for ensuring safety at sea.

Regarding the other options, avoiding turning away from the channel ensures that navigational drafts and traffic rules are respected. Reducing speed can be a safe maneuver and may be required in certain conditions, but it does not inherently put the vessel in a position of danger. Sounding a horn is often a signal to communicate intentions or warn others of a presence, which can be crucial in maintaining safe distances but does not conflict with the requirement to keep out of the way.
