Question 292Navigation General

The correct answer is D) Corps of Engineer towboat running empty-headed. The reasoning is that Corps of Engineers towboats operating in support of federal navigation projects have priority over other vessel traffic, including passenger vessels and pleasure yachts, when approaching a lock. This is due to the critical role these towboats play in maintaining federal waterways. An integrated chemical tow, while a commercial vessel, does not have the same priority as a Corps of Engineers towboat in this scenario. The other options, A) pleasure yacht and B) passenger vessel, do not have the same level of priority as the Corps of Engineers towboat when approaching a lock.
