Red over green lights for sailing vessels

[PaulRainbow]

A tricolour is required under Colregs:

For vessels less than 50 metres in length overall, IMO COLREG 72 describes the following
minimum visible distances for navigation lamps. Distances are in Nautical Miles.
Supplementary national approvals may also apply.
Vessels 0-12 metres / 0-40 feet in length:

White, Red, Green All Round lamps, 2 miles
Masthead lamp, 2 miles
Port and Starboard lamps, 1 mile
Stern lamp, 2 miles
Tri Colour lamp, 2 miles. (Sailing vessels under sail only)

Since Colregs specifically says a tricolour is required why did you say that?

You obviously didn't read the post properly have another look.

I had another look at both of your posts, highlighted the relevant parts in red. In both you claim that a tricolour is a requirement. You are mistaken (as usual), there is no such requirement.

If you know better, post the rule that says it is required.
