Which type of vessel must carry a VHF radio regardless of size?

A towboat over 26 feet in length must carry a VHF radio regardless of size because it is considered a commercial vessel that typically operates in more demanding and navigationally complex environments. The use of VHF radios is essential for safety, communication, and coordination, especially when engaged in towing operations or working in proximity to other vessels and navigation hazards. This requirement is established under maritime regulations to enhance safety and ensure effective communication on the water.

In contrast, while sailing vessels, recreational boats, and cargo ships under 100 gross tons may have specific requirements related to radio equipment, those requirements can vary based on size, operation area, and type of vessel. For instance, recreational vessels may not always be mandated to have a VHF radio if they are below certain length thresholds and not operating in heavily trafficked waters. Therefore, the obligation for a VHF radio aligns with the need for reliable communication for operational safety and risk management in commercial towing situations.
