Which action should be taken if a boater encounters an obstruction marker?

When a boater encounters an obstruction marker, the appropriate action is to change course to avoid the marked area. Obstruction markers are specifically designed to indicate the presence of hazards or obstacles that could pose a risk to navigation, such as rocks, shoals, or submerged objects. These markers serve as a warning to maintain safe navigation and protect both the vessel and its passengers from potential accidents and damage.

By altering course to steer clear of the obstruction, a boater ensures safe passage and reduces the likelihood of collisions or grounding. It is important for boaters to remain vigilant and heed the guidance provided by navigation markers to promote safety on the water.

Stopping immediately could lead to confusion or create a hazard for other boaters, while speeding through the marked area disregards the warning and increases the risk of an accident. Ignoring the marker altogether means the boater is not taking precautions that are essential for safe navigation, which is vital for ensuring the safety of all on the water.
