What is the purpose of the CG-3213 form?

The CG-3213 form serves the specific purpose of requesting changes to Aids to Navigation (ATON). This form is utilized by individuals or organizations to formally communicate their needs or recommendations regarding the positioning, establishment, maintenance, or alteration of navigational aids. Effective management of Aids to Navigation is crucial for ensuring safe maritime navigation, and the CG-3213 helps facilitate the efficient processing of these requests.

In the context of other options, while safety inspections, weather reports, and maritime permits are important aspects of maritime operations, they each require different forms and processes. Safety inspections are typically documented using distinct inspection forms, weather reports are often submitted through a different reporting mechanism, and maritime permits involve applications under specific regulatory frameworks rather than the CG-3213. Thus, the CG-3213 is uniquely focused on the navigation aids aspect, making it the correct choice for the question asked.
