Morale, Welfare, and Recreation (MWR) Boater Safety Practice Exam

Large vessels, even at slow speed, may throw what?

1. A strong current

2. A large wake

3. Additional crew requirements

4. Excessive noise

The correct answer is: A large wake

Large vessels, even when operating at slow speed, displace a significant amount of water due to their size and shape as they navigate through it. This displacement results in the creation of a large wake, which is the turbulent water left behind a vessel. The wake can be powerful enough to affect other smaller boats, driftwood, and even shorelines, making it crucial for operators of large vessels to be mindful of their speed to minimize the impact on surrounding watercraft and the environment. In marinas, narrow channels, or crowded waters, the waves produced by a large vessel can pose hazards to smaller vessels or paddle craft nearby, emphasizing the importance of understanding and managing wake generation.
