Navlights identification help
 
(sorry in advance if anyone saw this elsewhere - shoulda put it here first, SN is probably the better place to get an answer)

So we're fed up with winter and we're relocating this summer to an unnamed country on the eastern med starting with "i". Of course, first things first, before we have an apartment rented or job or schools sorted, I got on the bone with a nice South African lady from a sailing club to find out about joining, and she asks me what kind of certs I have. Uh, an Ontario boating license? Yeah right, that's not going to fly - I have to take like 6 exams covering coastal nav, electronic nav, mechanical, local maritime law & habours, plus one exam covering day shapes and one covering nav lights. I imagine a CG license over here would cover similar stuff.

Fortunately their Ministry of Transportation publishes sample question banks for each exam, and a cute supplement with 75 sample navlights and 16 day shapes ... I printed out the nav lights and made flash cards. My colregs reference is Wikipedia (is that a dumb idea?):
Most of them I can figure out pretty easily, for example:
http://ncsy.ca/tmp/navlights1.jpg

49 is a vessel constrained by draft, underway to port. 50 is a vessel with restricted manoeuvreability, engaged in underwater operations approaching and showing safe passage to its port (viewer's stb'd). 51 is a vessel trawling underway stb'd.

But what's this:
http://ncsy.ca/tmp/navlights2.jpg

A vessel under pilot, underway to port showing no safe passage on port side for some reason? Didn't seem obvious to me that lights were meant to be combined that way. Or is it a vessel under pilot, but not under command (is that a contradiction)?

And this:
http://ncsy.ca/tmp/navlights3.jpg

A vessel fishing (not trawling) underway approaching, but why the extra green light to the vessel's port (viewer's stb'd)? A white all-around there would show equipment/outrigger on that side ... what's this mean?

And this:
http://ncsy.ca/tmp/navlights4.jpg

A power-vessel to viewer's port underway approaching hip-towing a sailing vessel?

51 is fishing not trawling

57 is a pilot vessel not under commnd

68 has me stumped and curious

63 is towing along side - not necessarily a sailing vessel

This site has images as well as the rules. Navigation Rules Online

Good images here - http://portfolio.wuthering-heights.c...rpcslights.htm

Re 68:

A fishing vessel trawling but sorta looking to sweep mines too, can't quite decide?? ;-)

(ha ha-- I don't understand it either)

Trawling for mines?

On 49 - it may be over 50 meters.

63 Looks like a sailboat with hip tow.
or
A barge in international waters with hip tow.

If it was a barge in inland waters there would be a flashing yellow light on the barge and if it was a powerboat under hip tow it would show an all around white over the green/red.

Now, here's the kicker. I'm studying this right now for my OUPV test and answered without looking it up.... so I could be wrong. :)

68 a mine sweeper with the starboard green light obstructed by gear..or out. ?

That's a stretch, that means " I don't know" .. it's difficult enough to remember all these lights without trying to figure out rigging obstructions and bad lamps. Can't imagine they'd create a test question like that.

In either case, it's underway and coming toward you, whatever it is.

thanks
 
Thanks to everyone & especially Jack for the help and the great links.

I wouldn't put it past them that 68 is really a trick. Will have to go thru several hundred questions to see if any of them reference that pic :-)

I kinda doubt your average Ontario sailor knows more than identifying a boat as power or sail. Then again not many minesweepers here, and if you catch any fish they likely have 3 all-around green lights. And none of the harbours have been dredged (and they all need it, watch yer depth)....

68 just doesn't look right. It is a balagan.
