C'mon, I want more than one measly point!



What is a range, and how are two lights used to establish a range?

A range is two markers that should be kept in line with each other to
follow a channel, like looking down a gun sight. The upper light is the
further marker.

Care should be taken when following a range to know the marks for
*leaving* the range, I have seen plenty of range markers on dry land.




Why would three lights be used?

?? Dunno, maybe to mark a danger bearing?


What are the factors that determine a single light's visible range?

The height and the brightness




How are red sector in lights used?

To mark a danger zone or a "no-approach" zone.


Why are lighthouses all designed differently?

You mean why do they have different colored & patterned stripes etc on
them? So you can tell which is which, and thus where you are, if your
GPS is broken! However many lighthouses do have the same colors or
pattern.


At night, what danger should a helmsman be aware of when
steering for a lighted bouy that is being used as a way point?

Be wary of hitting the darn thing. Also, in some places, be wary of
hitting unlit markers along the same channel, or old out-of-service
marks. It can be a real PITA.


What is a Morse Code "A" light mean?

Sea buoy, the outermost channel marker entering a larger port. Small
sea channels won't have this.

Good questions Bart. Thanks
