which of the following accurately describes the two types of diver-down flags?

The two types of diver-down flags are the red flag with a white diagonal stripe and the blue-and-white Alpha flag. Both are used to warn that divers are in the water, but the Alpha flag is especially used to show a vessel is engaged in diving operations and has limited maneuverability.

What each one means

• Red and white diver-down flag: Signals that divers or snorkelers are in the area, so nearby boats should keep clear and slow down.

• Blue-and-white Alpha flag: Signals “I have a diver down; keep well clear at slow speed,” especially in maritime navigation and on vessels doing dive work.

Correct choice

If the question is asking which description is accurate, the correct statement is that the red-and-white flag marks the diver’s location, and the Alpha flag marks a dive vessel or diving operation.

TL;DR: Red-and-white = diver in the water; blue-and-white Alpha = diving vessel/operation.
