Which vessel is required by regulations to have an Official Logbook?

AI Explanation
The correct answer is B) A 100-gross ton tug on a trip between Baltimore, Maryland, and San Pedro, California. According to U.S. Coast Guard regulations, any vessel engaged on a voyage from one U.S. port to another U.S. port, regardless of the vessel's tonnage, is required to maintain an Official Logbook. This includes vessels such as the 100-gross ton tug traveling between Baltimore, Maryland, and San Pedro, California. The other options are incorrect because a 199-gross ton tug on a coastwise trip (A) and a 66-gross ton tug operating between states (C) are not specifically required by regulations to have an Official Logbook, unlike the 100-gross ton tug in option B.
