How do you know when you are operating your vessel at a safe speed?
In establishing a safe operating speed, the operator must take into account visibility ; traffic density; ability to maneuver the vessel (stopping distance and turning ability); background light at night; proximity of navigational hazards; draft of the vessel; limitations of radar equipment; and the state of wind, sea, ...
What is the best example of restricted visibility?
During periods of restricted visibility (such as rain, mist, heavy fog, or hours of darkness ), you should slow to minimum speed to give your vessel an opportunity to maneuver should the risk of a collision arise.
What should you do when approaching another vessel head on?

Why do boats pass on the right?
Most sailors were right handed , so the steering oar was placed over or through the right side of the stern . Sailors began calling the right side the steering side, which soon became “starboard” by combining two Old English words: stéor (meaning “steer”) and bord (meaning “the side of a boat”).
