Question 3457 Deck General

The correct answer is B) Water depth. The minimum size of an anchor buoy is determined by the water depth at the location where it will be used. Anchor buoys need to be large enough to maintain visibility and hold the anchor in place in the water depth where the vessel will be operating. Regulatory bodies like the US Coast Guard set guidelines for minimum buoy sizes based on typical water depths in different areas. The other options (A, C, and D) are not the primary factors that determine anchor buoy size - the water depth is the key consideration.
