When would you use the CG-4100S form?

The CG-4100S form is utilized as a supplemental boarding report form specifically within the context of Coast Guard boarding operations. When boarding team members conduct inspections, they may need to document additional observations, findings, or incidents that are not covered in the primary boarding report. This form serves as a tool to provide that necessary supplementary documentation, ensuring that all pertinent details are conveyed and recorded accordingly.

By using the CG-4100S form, boarding officers can maintain a comprehensive account of their activities, which is particularly useful for ensuring thoroughness in enforcement actions, operational reviews, and legal proceedings if necessary. It enhances the clarity and transparency of the boarding process, allowing for better oversight and review of the encounters that the Coast Guard has with maritime vessels.
