When is it illegal to operate a motorboat in Connecticut?

Operating a motorboat under the influence of drugs or alcohol is illegal in Connecticut, as it significantly impairs judgment, reaction time, and coordination, all of which are critical for safe boating. This law is in place to ensure the safety of both the operator and others on the water, as boating while intoxicated can lead to accidents and injuries.

While the other conditions presented may pose risks or challenges for safe boating, they do not constitute a legal prohibition in the same way. For instance, operating a motorboat during the night could be permissible with proper navigation lights and safety equipment. Rough weather conditions might make boating unsafe, but it isn't inherently illegal to operate a boat in such conditions—it's the responsibility of the operator to assess their capability in those circumstances. Lastly, carrying more than the maximum number of passengers is a safety concern, as it can lead to capsizing or loss of control, yet violating this guideline doesn't automatically equate to a legal consequence regarding the operation of the boat itself.
