What guidance is provided for vessels under 20 meters regarding marine radios?

Vessels under 20 meters are often exempt from carrying a marine radio under certain regulations and guidelines. This exemption can vary based on country-specific legislation and the intended use of the vessel. For many recreational and smaller commercial vessels, the requirement to carry a marine radio does not apply, particularly if they operate in coastal or inland waters where other means of communication may be available.

It's important to understand that while larger vessels have stricter requirements due to their increased risk of operating at sea and the need for reliable communication, smaller vessels may rely more on visual signals or alternative communication methods. However, this exemption doesn't diminish the importance of having a reliable means of communication, especially for safety purposes, which is why many operators choose to carry a radio voluntarily regardless of regulation.

Monitoring channel 13, which is designated for bridge-to-bridge communications, is typically not sufficient as a singular communication method, and the operation in international waters generally requires more stringent compliance with communication standards. As such, understanding these exemptions and regulations is crucial for safe boating practices.
