It all depends on what and where the boat will be sailed.
If I were to cross the Altlantic I would have a mast and a deck red/green, plus the white one on the mast.
The night sailing I do, is coastal and short, and mostly sail during the day (hey AFOC Sailaway scew you..I sail at night also...). So why do I need the mast red/ green?? I don't
I have the white required in may mast though..
Like I said, to me each case is a case...don't you agree???
SA you'r an AFOC
