If the other vessel still does not take action, what may you do to avoid collision?

When there’s a risk of collision and the other vessel does not change course or speed, you must take action to keep clear. If there is enough sea room, turning to the starboard (to the right) and passing astern of the other vessel is a sensible maneuver. This option moves you away from the other vessel’s path and allows you to stay clear by going behind it, reducing the chance of crossing noses or entering its stern arc. It aligns with the obligation to take early and decisive action to avoid collision when the other vessel isn’t doing so.

Keeping your course and speed would leave you on a collision course. Drastically slowing down or stopping can be unsafe or impractical in traffic and may not provide reliable separation. Passing ahead of the other vessel could put you in its path if it doesn’t maneuver, increasing risk instead of reducing it.
