When is it illegal to operate a boat in Maine?

Operating a boat during times of impaired judgment due to alcohol or drugs is illegal because it significantly increases the risk of accidents and puts the safety of all on board, as well as other vessels, at grave risk. Maine, like many states, has strict laws against boating under the influence (BUI) to ensure that all operators are alert and capable of making sound decisions while navigating. Alcohol can impair a person's coordination, reaction time, and judgment, which are critical for safe boating.

While operating a boat in heavy rain or fog can be hazardous, it is not specifically illegal unless visibility is severely compromised and you are not taking necessary precautions. Similarly, operating a boat without proper lighting after sunset or carrying more passengers than the boat is certified for can also lead to dangerous situations but are enforceable under specific regulations rather than being outright illegal like operating under impairment.
