All around red over green makes a fine sailing machine and if someone asks just say you like to live the Christmas
spirit, then while retaining that Christmas
spirit take the time to explain them the alternative light configurations so that they become the wiser.
But we also see sailors of boats less than 20 meters [a.k.a. metres] displaying a trilight configuration on the top of their mast
, while simultaneously running red and green side lights at deck
level which is so
no, no, no.
And / or displaying a white stern light at the top of the mast as part of the tricolor configuration AND simultaneously displaying a white stern light at deck
The inherent issue being that it becomes difficult to range the vessel, and / or to determine as to whether the lights indicate that there is / are, one or two craft due to the distinct heights of the twin sets of running lights being displayed.
It is either / or, never both mast top tri-lights and deck level running lights.
Red over green also makes for a fine oared or paddled machine.
Not all vessels are two sheets
to the wind
Ya got three choices of night lights arrangements for under 20 meters unpowered vessels. At times it seems that three is too many, because just one is hard enough for many to remember and comprehend.
Then toss into the mix the significant percentage of red green colorblind navigators and the realization that all they see is shades of green and muddy green, good luck with that. If you ever found it confusing trying to discern red and left and green and right, try just seeing green and green, seeing that can make you want to scream. Kind of like me yelling to my pop, "Dad, the light is RED!" when approaching an intersection at night and your not sure he recognizes that he needs to stop [give way] and not "stand on" when driving. E.g., particularly as to a flashing yellow light, indicating Continue with CAUTION, or a flashing red light indicating STOP.
Makes one wonder if seeing many shades of green is better than seeing fifty shades of grey or gray. So glad we don't use grey over gray as navigation
By the way, the USCG has recently issued a safety
warning that sailors are purchasing
navigation lights that are appropriate for powered vessels as to their comparatively limited / narrowed range of their horizontal angle of light emissions and using them on sailing vessels. Sailing vessels have a tendency to heel over and require navigation lights that have much wider range of horizontal angle of light emissions so as to be able to be seen at all angles of tilt. The problem being amplified by the fact the products are marketed without making the distinction of their horizontal emission angle and certification
