The subject seems to be sinking-avoidance for the sleeping single-hander. Clearly sleeping is illegal and there isn't a legal lighting
Let's assume a few things:
* A large vessel will try to avoid anything they see.
* The speed of a single hander (some racers excepted) is so low while sleeping (most would reef) that the speed of the boat is of limitied consequence in avoiding collision
with a large vessel making 18 knots. They will see you as either stationary, drifting, or very slow.
* The simplest vessels to see and identify are generally active comercial fishing
boats and cruise
ships; it's not the nav lights that give them away, it's the sheer number of lights. There is nothing in the rules stating that additional white work and cabin
lights cannot be vissible.
So, with the advent of huge solar
banks and low draw LED lighting
, would illuminating the sails
continuously make some sense? Sure, while sailing it would cook your night vision, but the assumption is you're sleeping. The battery
draw down during a cat nap won't matter. I know in some busy harbors it is common to leave a deck
light on, for the benifit of late night drunks who don't look up. Thoughts?
No, not good practice, but we're talking collision avoidance far off-shore (if you're sleeping in-shore, you're a nutter).
