Rules of the Road: BOTH INTERNATIONAL & INLAND Vessel "A" is on course 000°T. Vessel "B" is on...

Bearing is the relative angle between two objects. This is a head on situation.

This is an incorrectly worded question. ROBIUS is correct, given the True compass courses stated, both vessels are headed in the same direction with only a 5 degree difference in course. The correct answer is probably "A", maintain course (or alter course to starboard.

SEMICOLONSUTRA is correct. Vessel B "bears" 355T from vessel A. The question never says what "course" vessel B is on, but probably something close to 175T. This is a head-on situation.

Rule 14 (a) [ Unless otherwise agreed ] when two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk of collision each shall alter her course to starboard so that each shall pass on the port side of the other.

This is not a head on situation

The bearing are only there to confuse you; the questions clearly tells us this is a head-on situation. What is the best answer? Shawn made a great point of the inland rule being different and allowing stbd to stbd, but the QUESTION DID'T tell us there was an agreement; AND the answer must work in BOTH INTERNATIONAL & INLAND. Therefore, "C" is the only answer.

After further review of the question, I’ve come to the conclusion that the word of importance here is “bearing”. Your heading is 000T with a ship bearing to you at 355T(port bow). Assuming its a head on situation, the vessel at your 355T is the give way vessel and shall alter her course to starboard for a port to port passing. Please be mindful that when talking about “True bearings” it is always going to be compared by TRUE NORTH.

There is no give way vessel in a head on situation. For anyone not reading this as a head on situation, as has been stated by others, Vessel B "bearing" 355 degrees. She is not heading 355, or steering 355, but bearing 355 from Vessel A, which is 5 degrees off of Vessel A's bow. Vessel B could be bearing 355 and steering a northerly course, but she is not, as the question states that she is on a course such that involves head-on situation. In effect this question is asking "what action should vessels meeting head on take"? Rule 14 says for power vessels (which by the way this question does not specify), alter course to starboard and pass port to port
