That was a few years ago, when LED flash light was just emerging. Tom said they were too bright and kill his nite vision.
It is a valid point that too bright a light source will kill the nite vision. But I think the concern is blown out of proportion. My nite vision will come back less than 5 min. It is unlikely that within that 5 min, a tanker is going to run over you. It is not ideal, but it is not fatal.
Likewise I often complaint about Full Moon, it is too damn bright. I lose my nite vision... :laugher. I prefer sailing in pitch dark. [
are you for real or joking cant make it out but for me one of the most beatiful things in life is sailing with a full moon on big trade winds and rollers...
the sheers beaty and sounds and the way the sea glimmers, is a "sight" to behold
that and the ease of being on watch..you can see almost everything
no need for even running lights jajaja
