What should a boat operator do in restricted visibility?

In restricted visibility, a boat operator should reduce speed to a safe and manageable level, maintaining a lookout for other vessels and navigational hazards. They should sound appropriate sound signals as required and ensure that navigation equipment, such as radar and GPS, is functioning properly. It is also important to keep a safe distance from shore and avoid navigating in narrow or congested waters if possible. Finally, the operator should be prepared to stop or take evasive action if necessary.
