.................. There are many places where there are airports in close proximity to anchorages... really big sailboats also use a all around red as that is what pilots look for.. not white lights that tend to get lost in the background lighting when viewed from above.
Except the mention of a blue light in post 1....
Plus you have to be a huge sailboat to need aircraft warning lights.
As I posted above, ignoring the COLREGS and making up their own laws.
This isn't a Canadian thing, it's a status thing. It's an aircraft avoidance light, has nothing to do with Colregs, and everything to do with being the most impressive vessel in the anchorage. So impressive, in fact that it merits aircraft avoidance lighting. Besides, you never know when your charter seaplane will approach to drop off the kids and fresh baguettes.
They're not for the little people. You can only aspire to such lofty ambitions.
Anything in the Regs prohibiting a flashing anchor light? It could be more easily seen. But, as the light is "off" for periods, in those periods the boat is not displaying a light at all, which is non compliance.One night in Cayo Costa there were two power boats with flashing white lights. Not strobes, but 1/2 second on, 2 or 3 seconds off. I can't remember anything like it in the Nav Rules.
