Nav Lights
« on: January 26, 2015, 11:25:13 PM »

Hello Everyone.
Just a brainteaser, navigation lights are now on boards painted the same colour as the lamps, but when were they on a black painted board with the red and green lamp the only source of colour, I am building a Clyde puffer (albeit a fictional one) and I am curious to know when and why they changed?.
Here's hoping.

Collision regs changed in 1972 with the new act. Previously sidelights (not navigation lights) were mounted on screens painted the same colour as the lamp filter. After the new act sidelights were mounted on screens painted non reflective black. Thus only direct light from the filament is projected and no light is reflected from the screen. The screen then does what it says and stops the light from being seen where it's not meant to be seen.

Morning Howard....... :embarrassed: ...I am not sure that your first statement is correct...if you GOOGLE 'navigation lights on vessels' you will still find 100's of recent examples where the red & green lamps are mounted on flat black background box's...... Derek

Why bother with Google when Jerry has given the definitive answer?

Interesting that, I had often wondered the same thing, thanks for the clarification.

Ned and Derek, think we have a wee terminology thing going here.

Jerry said.
Previously sidelights (not navigation lights) were mounted on screens painted the same colour as the lamp filter.

Excuse me if wrong, but think Derek took this sidelights, (the green and the red) as being navigation lights, thus as NOT being mounted on painted screens.
In this context I assume navigation lights being the various WHITE lights required at various locations, whilst SIDE LIGHTS are the red and green usually mounted at the sides of the vessel.

Shoot me if I have got these two posts wrong, and on that note, will get ma-hat-ma-kote, and stroll out stage left and under the door.

cheers

A ship is equipped with a set of lights. We generally refer to them as navigation lights. We split them up into:- steaming lights ( the white ones on the masts), stern light (aft) and side lights (only show on one side). There are also "special lights" eg fishing lights, restricted ability lights et al. Because it gets complicated we have a set of rules called "The international Regulations for the Prevention of Collision at Sea 1972". These rules are written in a form that is legally clear and concise, leaving no ambiguities or confusion. Google them and read them carefully(in my day before 1972 we had to learn them all off by heart and be able to quote from any part of them at Oral Exams) and you will understand the whole thing. Each light on a ship has to have a specified colour, range and arc of visibility. Sound signals are also now scientifically defined. 
Otherwise this thread will go on and on into the depths of confusion similar to left and right handed props. 
Jerry.

Depending on the vessels operations, Red and green and yellow lights are
used to denote fishing,restricted manoeuvring or towing.
Side lights denote the port and starboard sides and in
conjunction with masthead white lights show other vessels the
course that vessel is taking..
They can be confusing as when we were running sounding lines off
Anglesey showing Red White Red we were confused with the
Liverpool pilot vessel Red White by an incoming vessel.

 :o.. I tend to agree with JerryC........lets voluntarily close/can this thread before someone runs out of puff   >>:-(

Sorry Howard   ...if you are more confused  {-) that when you opened the thread.........

Having said all of this....I suggest it would be safe to paint the running light box's on your Clyde Puffer with a flat black side, base & background & have the lamps as red & green ....Derek

As 'Navigation Lights' crops up here every couple of weeks or so, why not sticky a topic at the top giving the definative explanation?

Something along the lines of this chart.......

Thank you Guys.
It never suprises me how quickly and accurately replies are to a question posed on the forum, thank you all for your help. I had to smile when a suggestion that the topic be locked down, just confirms what my Wife says, I could start an agument in an empty house. Howard Q.

Some discussion on the colour of navigation side light, light boards. About 1975, the MoDn altered all the side light housing to comply with the 1972 regs which had just been ratified, from red and green colour to matt black, also for the first time the cut off point for seeing these lights had to be from 22.5 degrees astern to dead ahead, the most critical being ahead, i.e if you were one degree past the ahead or from it you only saw one light, so you only saw the dreaded triangle absolutely dead ahead of a vessel, this was for safety considerations in the collision regs. So only Puffers in preservation and about three in number which did survive on the Clyde in trade until the late 1970's actually have black side light boards.
