Question 4127 Deck General

The correct answer is B) The turning diameter increases when turning a vessel in shallow water. This is because in shallow water, the vessel's interaction with the seabed or bottom causes increased drag, which results in a larger turning diameter compared to turning the vessel in deeper water. The increased drag from the shallow water slows down the vessel's rate of turn, leading to a larger turning circle. The other options are incorrect: A) is wrong because the turning diameter does increase in shallow water, C) is wrong because the rate of turn decreases, not increases, and D) is wrong because the rate of turn actually decreases, not increases, in shallow water conditions.
