How should passengers be instructed to behave while the vessel is in motion?

Passengers should be instructed to remain seated unless necessary to move for several important safety reasons. When a vessel is in motion, stability can be compromised, and sudden movements can lead to an increased risk of falls or loss of balance. Remaining seated helps maintain the vessel’s balance and reduces the likelihood of accidents. Passengers may be required to move in specific situations, such as in an emergency or to assist with a specific task, but generally, it is safer to stay seated while the boat is underway.

The behaviors suggested in the other options do not prioritize safety. Moving around for balance can create unnecessary risk, standing up for a better view can lead to falls, and consistently moving to stay warm is not a practical approach on a vessel and can distract from maintaining stability. Thus, the recommendation to remain seated is rooted in ensuring the safety and well-being of all passengers on board.
