Which document is NOT required during the boarding progression of an Ecuadorian flagged vessel?

The correct answer identifies Form 5 - Crew member identification as the document not required during the boarding progression of an Ecuadorian flagged vessel. While crew member identification is crucial for verifying the identities and eligibility of individuals on board, it is not typically mandated as part of the standard documentation necessary for the boarding process itself.

During a boarding, authorities focus on operational and safety documents—these include forms that pertain to actions taken during the boarding (Form 1), responses to those actions (Form 3), and the results following the boarding (Form 4). These documents help ensure that the boarding is conducted efficiently, legally, and in accordance with international maritime guidelines and the specific regulations of Ecuador.

Thus, while crew member identification is important for overall vessel management and compliance, it does not directly factor into the required documentation for the initial and procedural aspects of the boarding operation.
