What type of communication equipment is essential during a boarding?

VHF radios are essential during a boarding because they are specifically designed for maritime communication, facilitating reliable and clear communication between vessels and shore stations. VHF radios operate in the very high frequency range, which is ideal for short to medium-range communication, making them an effective tool for coordinating operations during a boarding. They provide a dedicated channel for emergency communication and are standard equipment for most vessels, ensuring that boarding officers can communicate directly with each other or with command centers while at sea.

In contrast, satellite phones can be used but are not always practical or reliable due to their dependence on satellite coverage and potential connectivity issues at sea. Walkie-talkies, while useful for short-range communication, may not have the necessary range or clarity for coordinating maritime operations effectively. Cell phones often face limitations at sea, such as poor reception or no service in many areas, which can hinder timely communication needed during critical boarding situations.
