I sometimes navigate with a yellow strobe...that should make me a hovercraft or a submarine ( amber light) , right?

Or (more commonly, and depending on the periodicity of the light) a barge being pushed.

If I remember correctly from my Captain's exam, Yellow flashing is for hovercraft ( in non-displacement mode), double yellow flashing alternatively ( Port or Stbd) for purse seine gear fishing.The tow ( submerged or semi-submerged) is a fixed yellow light ( makes sense to associate the speed of flashes with the sense of the vessel's speed)

24/7,

Welcome aboard! What took you so long?

Or is this a different 24/7? YF, right?

As most of us know, NMMA/ABYC only addresses nav lights on navigable waters, both inland and offshore. The Coasties and local Marine Patrols tend to mimic the nav light issues. It is when you draw attention to yourself by exhibiting a light or light pattern that purports you to be something your not that will invite the prying eyes...

Remember its a "SPECIAL" flashing yellow light on the bow of the tow!

I was thinking the actual USCG rule was that you can have as many lights as you would like as long as they don't negatively affect navigation lights or a proper look-out.

Submarines navigating on the surface use a yellow flashing light--in fact, it flashes morse for "S", three dits.
