Chapter 2 X Boating Law, Navigational Rules and Navigational Aids

Poor and Restricted Visibility Poor and restricted visibility may be caused by fog, mist, falling snow, heavy rainstorms, or even blowing sand or smoke. For all vessels not in sight of one another when navigating in or near and area of restricted visibility, the navigation rules require every vessel to slow to a minimum, safe speed according to the conditions present. You should navigate with extreme caution and take action to alter course in ample time to avoid collision. When underway in restricted visibility, you must sound a warning signal at least every two minutes. ƒ A powerboat should sound one prolonged blast every two minutes. ƒ A sailboat under sail should sound one prolonged blast, plus two short blasts, every two minutes.
