I will maintain my course and speed. The other vessel is being overtaken and is therefore obliged to keep out of the way by rule 13.

The vessel is on a steady bearing and the distance is closing. I will therefore take avoiding action, altering course to starboard and sounding one short blast under rules 14 and 16.
