What is a range, and how are two lights used to establish a range?
To mark a direction, usually a channel, at night. One higher than the other,
then line 'em up.
Day or night markers, used to mark the preferred line for a marked channel (may
or may not be centerline).
Why would three lights be used?
Don' t know.
Never seen this, but would guess it might used to show the edges of a narrowing
channel, to a certain point.
What are the factors that determine a single light's visible range?
G will leave this for someone else.
How are red sector in lights used?
Keep clear.
Why are lighthouses all designed differently?
Identify location by color scheme or other attributes.
At night, what danger should a helmsman be aware of when
steering for a lighted bouy that is being used as a way point?
don't hit it or the jackass tied to it using his BBQ; keep to the appropriate
side.
What is a Morse Code "A" light mean?
safe water at center of a channel
This is on the first buoy (or last, depending on your direction) you will
encounter at major ports. Can NORMALLY be passed on either side, but this is
not always true .... check your chart and local regs....called the "Sea Buoy"
