Question 413 Rules of the Road

The correct answer is A) A sailing vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), Rule 18, a vessel constrained by her draft has the right-of-way over a sailing vessel. This means that the sailing vessel must avoid impeding the safe passage of the vessel constrained by her draft, as the latter is limited in her ability to maneuver. The other options, B) a vessel not under command and C) a vessel restricted in her ability to maneuver, also have the obligation to avoid impeding the safe passage of a vessel constrained by her draft, but they are not the specific answer to the question, which is asking about the vessel that shall avoid impeding such a vessel.
