The "Rules of Navigation" which should be aboard your boat say
exactly. If your boat is short enough that the book is not required it
still is a good idea. It helps to understand the lights you see on
other vessels.

I am not on my boat, but the white light must be above the R/G when
the vessel is "propelled by machinery." The usual position for
sailboats, partway up the mast, is fine.

The only complication may be if your red/green is a masthead lantern.
Then you need separate running lights for powering.

There is nothing saying the forward white (steaming light) must be at
a different elevation than the stern light. Indeed, on motor boats it
is often one all-around light.

Does anyone know where the LEGAL position of a streaming light is
supposed to be? I've had people tell me "the top of the mast", and
"3/4 of the way up the mast", and "at the lower spreaders".

At the top of my mast [Islander 29'] I have two lights. One is a
white 360 degree light [anchor], and the other is white, but shows
only 180 degrees [?] forward. I assume that the second light is a
streaming light, but wonder if it's "legal" where it's mounted?

Appreciate a reply via e-mail,,,,,
