A vessel is overtaking when she approaches another from more than how many degrees abaft the beam?

• A. 22.5°
• B. 45°
• C. 90°
• D. 11.25°

Answer: (A)

Overtaking is defined by how far behind the other vessel lies, using the boundary of 22.5 degrees abaft the beam. If another vessel approaches from behind and more than 22.5 degrees abaft the beam, she is overtaking. The 22.5° line marks the limit between the non-overtaking (slightly behind the beam) and overtaking sectors, helping determine who must keep clear. In this question, the approaching vessel is beyond that 22.5° threshold, so it’s considered overtaking.
