How far must you slow down from any US naval vessel?

The correct answer is 500 yards because this distance is the standard requirement set by federal law to protect US naval vessels. Approaching a naval vessel within this distance requires boat operators to reduce their speed to avoid potential hazards and ensure safety. This regulation helps prevent interference with naval operations and protects the security of these vessels.

Boaters are advised to be vigilant when navigating in proximity to military vessels and to understand the potential implications of failing to abide by these regulations. The distance of 500 yards is significant enough to allow naval ships to operate without disruption while providing a buffer zone for safety. Adjusting speed, regardless of vessel size, is a critical aspect of maritime safety protocols, particularly around vessels that are vital to national security.
