When was it agreed that port lights should be reg and starboard green

[Beadle]

Spot on

Of course there would be no red and green lights in Viking days.

They would have a torch burning

Further if you imagine steering a longship with a big square sail full of wind, you would have a much better view to starboard than to port. So if you saw a burning torch on a dark night it would have to be to starboard and highly likely that he couldn't see you. So you turned to starboard to pass behind him. Just like we do now.

You sure about that?

Didn't know the Vikings were that advanced & had 'power driven vessel' rules!

Surely, a vessel seen to starboard when sailing a big square sail, would have been a 'windward vessel on the same tack', so would have been give way vessel with yours as stand on!

Oh

Didn't really set out to get into a colregs punch up

Since power wasn't an option in Viking days I guess the argument wouldn't really apply unless you count oars I suppose,

Personally I wouldn't choose to dispute right of way - err I mean stand on vessel issues - with a boat full of norsemen with big choppers

I suspect Colregs issues in those days were more likely settled with a battle axe, anyway.

"I suspect Colregs issues in those days were more likely settled with a battle axe, anyway"

I suspect that were some of the "debates" on here were in person rather than by remote electronics they still would be.

Although in fairness it seem a while since we did have a real ding dong colregs bash

 

[mireland]

time for a change?

Predominant form of colour blindness is red green I believe so maybe not the best. Anyone feeling artistic and able to offer a couple of alternatives?!

Thought this was interesting - the NY Times reports on test of colour perception for colregs purposes from 1892.

The family has been discussing and now have the following questions

When did ships start displaying green and red navigation lights?
When was it agreed which side they should be on and why?
TS

Why? Do you want to propose to have them swapped over in the UK for one more opportunity to do the opposite of what everyone else does?
