In what situation would a coxswain require a review of navigational protocols?

A coxswain requires a review of navigational protocols after not standing a night watch for an extended period, such as 30 days, due to the potential for skill deterioration and reliance on accurate navigation during night operations. The navigation procedures can change, and there may be updates to protocols or equipment that the coxswain needs to be familiar with. Given the complexities and added challenges of nighttime navigation, a refresher ensures that the coxswain is prepared and up-to-date, minimizing risks associated with navigation inaccuracies during shifts.

While the other scenarios could involve training or assessments, they do not specifically address the need for a review due to the passage of time since the last related experience. After a successful deployment, a coxswain may handle different responsibilities or experiences that don't inherently require a review of navigational protocols. Crew rotation may introduce new personnel, but it doesn’t necessarily require a review for the existing coxswain unless they are specifically changing roles or responsibilities. Regular training sessions are typically for enhancing skills rather than necessitating a review for lapses in operational duties.
