Light Display

[OzGirl]

I'm a long way from the boat, almanack etc, so help me fellas. What does a red over green over red light display indicate? Similarly, black ball over black triangle (point up) over black ball? G'day folks

Red over green over red = I can only imagine this could be a sailing vessel under 20mtrs under way (As a sailing vessel may, optionally exhibit all round, coloured sailing lights at or near the masthead, the upper lights being red over green, and together with a port side aspect view would give you red over green over red.

Black ball over black triangle (point up) over black ball, don't understand, BUT if the black 'point up triangle' you mention was a diamond shape = Vessel with limited ability to maoeuvre. For information this would be red over white over red (vessel under 50 mtrs) for night time recognition.

Hope it helps.

Without checking the col regs, I believe that if a sailing vessel is showing the (optional) red over green all round lights near the mast head, she MUST also be showing red/green navigation lights lower that the all round lights. She cannot show the tricolour at the masthead at the same time as the optional red & green lights..

Therefore this combination still remains confusing!

As Happy said, you could get this combination when viewing the yacht from her port side, although the bottom red might not be directly under the green.

sounds like harbour signals. red/green/red in Plymouth means no shipping movement

Some clubs also use this arrangement of light for the club boat marking a race finishing line - not sure how common though.

Yep, could well be, (I'm not used to harbour signals). Depends how close the bottom red is to the middle green.

w.r.t. harbour signals, doesn't it mean ask for permission before entering?

Like this Happy

Not really as Oz girl describes.....

Ok, this is bothering me, the closest I can find is rule 27

(b) A vessel restricted in her ability to manoeuvre, except a vessel engaged in mine-clearance operations, shall exhibit:

i. three all-round lights in a vertical line where they can best be seen. The highest and lowest of these lights shall be red and the middle light shall be white;

ii. three shapes in a vertical line where they can best be seen. The highest and lowest of these shapes shall be balls and the middle one a diamond;

iii. when making way through the water, a masthead light or lights, sidelights and a sternlight, in addition to the lights prescribed in sub-paragraph (i);

iv. when at anchor, in addition to the lights or shapes prescribed in sub-paragraphs (i) and (ii), the light, lights or shape prescribed in Rule 30.

Are you sure this is not what was asked Ozgirl, seems to be the closest to what you describe.

3 fixed lights; red over green over red: Movement of shipping within the Dockyard Port prohibited.

Other than these local rules, there seems to be no international light or shape regulations that correspond to the strict interpretation (other than looking at a sailing boat at an obtuse angle) Wind up, or esoteric rule that no one knows of.

Where's Byron!

I think it has just been a wind up /forums/images/icons/wink.gif

Not at all - this was a genuine request for advice. You ARE a cynical old wotzit, aren't you! But I realise now that I should have explained that the display wasn't on a boat as such, but on a hulk (sort of ex-boat but still afloat) that was being used as a service platform for refuelling, amongst other things - in a port/dockyard. So it looks like BrendonS gets the prize. Many thanks, O Wise One
By the way, the forecast is for 29C and sunny here today so I'm off for a days boating.
G'day folks
