You are the officer on watch and have taken the final drafts of your vessel prior to getting underway. The vessel takes departure and proceeds outbound in a narrow channel. As the vessel increases speed and gains momentum, what will be the effect on the mean draft?

Correct Answer: Option C — it will increase in comparison to the sailing drafts

As a vessel gains speed in restricted shallow waters, the Bernoulli effect increases squat, causing the vessel to sink deeper into the water column and increasing its mean draft compared to static sailing drafts.
