Strange Nav Lights

[tompaddock]

Just come across this picture on the homepage.

Can't work out what the navigation lights mean:

White
Red
Red

(am assuming that the white's a normal steaming light for a power driven vessel)
Then normal P/S Lights.
Any hints?

Not sure what picture your refering to but normally a white over red represents a commercial vessel carrying a pilot.

The two red ones also indicate "A vessel not under command ", in this case under way, but then the white top light should not be on/visible?

[tompaddock]

Yes, indeed, I thought pilot too, but there are definitely 2 all round reds. Very weird.

I thought a vessel not under command, but then it was planing at about 40knts, so i'd hope not!

Maybe this?

ANNEX II : Additional signals for fishing vessels fishing in close proximity 1. General
The lights mentioned herein shall, if exhibited in pursuance of Rule 26(d), be placed where they can best be seen. They shall be at least 0.9 metre apart but at a lower level than lights prescribed in Rule 26(b)(i) and (c)(i). The lights shall be visible all round the horizon at a distance of at least 1 mile but at a lesser distance than the lights prescribed by these Rules for fishing vessels.
2. Signals for trawlers

• (a) Vessels of 20 metres or more in length when engaged in trawling, whether using demersal or pelagic gear, shall exhibit:
  • (i) when shooting their nets, two white lights in a vertical line;
  • (ii) when hauling their nets, one white light over one red light in a vertical line;
  • (iii) when the net has come fast upon an obstruction, two red lights in a vertical line.
• (b) Each vessel of 20 metres or more in length engaged in pair trawling shall exhibit:
  • (i) by night, a searchlight directed forward and in the direction of the other vessel of the pair;
  • (ii) when shooting or hauling their nets or when the nets have come fast upon an obstruction, the lights prescribed in 2(a) above.

Hi, in all probability these lights show a vessel aground. The two reds signify a vessel 'not under command' whilst the single white signifies (in this case) a vessel less than 50m in length at anchor. Combined they indicate a vessel aground <50m.

This is a useful site http://www.bosunsmate.org/seamanship/lights.php

Thank you, sir.
I love Bosun's Mate!!
I'm afraid, though, I must disagree, it appeared to be a lifeboat travelling at 40knts.
Thank you, again.

But vessel on ground don't show "Then normal P/S Lights" (or should not show anyway)?

Yes, indeed.

we reckon it's a trawler whose nets have come fast upon an obstruction

just out of curiosity, are we talking about the same picture, the one of the orange commercial cabin rib as seen from the bow?....i keep refreshing the home page but seem to find every other picture except this one?

From memory though it looks like a pilot vessel....

Yes, indeed, it's Orange, with a cabin.
There's also a side shot of the same vessel.

I thought it was a pilot, but this strange red light popped up and I got all confused, I did!

So it's either a rib not under command, with running lights on, at 40 knts (SCARY THOUGHT!), or an orange fishing RIB with stuck nets (@40 knts :S)

I'm starting to think it's probably just a pilot boat with a red light fetish, really!

[Anchorhandler]

what you sometime's get is two reds either side of the mainmast so to give full 360degree coverage. i have seen it before when picking up a pilot that from certain angles especially from above, it looks like two reds showing under the white.

Although i still can not see the picture i'm guessing that it is probally this.

All is explained: http://rib.net/forum/showthread.php?...=lights&page=2

[tim griffin]

if it's th Parker rib on the front page then it was to display all lights while under going a sea trial if I remember Ostrada does post on here.Or ask Andre

If you want to learn about lights www.sailtrain.co.uk is another good site.
Also Rulemaster Pro cd rom is good .

Ah thank you!
That explains it!

Purely out of interest, why do they need 2 all round reds?

But thank you, sir. You've unconfused me (again!)

[Anchorhandler]

Yes!!! finally fell on the right picture just when i was'nt trying too....typical

Commercial vessel must have the ability to show 3 all round reds which indicates the vessel is limited in its ability to maneuver or constrained by it's draught.

There may be other reasons for having the reds but this the one which imediately springs to my mind......

From what i remember though, i thought this only applid for vessels above a set tonnage....but dont quote me on this as certain vessels like tugs etc....can show these also.
