🔍 Key Concepts

• Vessel Bridge-to-Bridge Radiotelephone Act scope and purpose • Minimum length or tonnage thresholds that trigger bridge-to-bridge radiotelephone requirements • Which types of operations (e.g., towing, passenger for hire, size-based) are specifically mentioned in regulations

💭 Think About

• Look for which option best matches the idea of large, maneuvering-risk vessels that need to communicate quickly with other bridges and ships • Consider whether the Act focuses more on size (meters/feet/GT) or on type of service (towing, passenger, aircraft) • Ask yourself which option describes vessels most commonly found in congested or restricted waterways where bridge-to-bridge communication is critical

✅ Before You Answer

• Eliminate any option that involves craft not normally regulated as vessels for bridge-to-bridge VHF (think about aircraft). • Compare the specific length/tonnage figures in the choices with what you remember from the regulations on bridge-to-bridge radiotelephones. • Check which choice most closely matches the phrase "while navigating" in areas where collision avoidance radio communication is important.
