Navigation Lights

[ebb]

C'pete, I finally see what you are getting at.

Any boat with an all round white light ON and not anchored is a boat under power.
Any boat under power with an all round white steaming light will not have its STERN light on.
But any boat will have its port and starboard lights on.
That means, in effect, that the masthead tri-color cannot be on.... Because the tri lights cannot be turned on and off separately.
Because when steaming with an all round white light, the white stern light part of the trilight cannot be on at the same time.

But I can see that in a sailboat not switched correctly that the tri-color and the all round white could be on at the same time. And that would cause confusion for the observer.

That's why a sailboat our size should have separate port and starboard and stern light at deck level.
Cruising or offshore I would definitely include the tri-light and the all round white
anchor light.

[It's a whole other dual fixture, but I know I've seen an all led steaming light and amp-eating deck light combo that is mounted at spreader height. Personally this is an excellent idea. And if attracting attention at sea these lights are perfect.
However, for picky regs I don't see how cutting a major portion of the steaming light by mounting it on the front of the mast makes it legal.
But do see that the mast will create a beneficial shadow for the poor guy in the cockpit.]

Also, I don't recall seeing a halfmast steaming light shown in any required nav light diagram.
Conceivably it is less legal than a tri-light with an all round anchor/steaming light.


Just to make things difficult: I have a diagram here that shows a white MASTHEAD steaming light that has a wedge blacked out on the aft side that corresponds exactly with the stern light wedge shaped light down on the DECK LEVEL. Also the red/green side lights are on.
Thus, you'd have your three normal deck level lights with a three sided white masthead steaming light.
This evidently conforms exactly to USCG rules for a sailboat under power.


BUT, a masthead 360 white light IS also Regulation for steaming under power.....
Have the diagram to prove it.
THAT IS IF YOU TURN OFF THE DECK LEVEL STERN LIGHT AND keep your sidelights on.
That seems simple enough.
As a bonus you get an allround anchor light when the side lights are off.

Whewww!

The power draw of the steaming light is not much of a concern, if your engine has a charger.

I don't think powerboats are really looking for lights up off the water. I look for masthead lights, and I see them frequently, although the light usually turns out to be a plane, helicopter, star, tower or something

You can even mistake a traffic light on land for another boat

By the way, I called Sea Dog about their new LED lights C-147 mentioned above. The guy wasn't familiar with the product but eventually told me they don't make an LED stern light. I haven't been able to find this line of products for sale anywhere yet.

C'pete,
Thanks for keeping the discussion going.

Did get on to
www.sea-dog.com
new items
where we find a selection of stamped 304 LEDs nav lights:

pair of horizontal mount port and starboard lights (400035)
a combo horizontal mount bow light (400050-1)

a rectangular vertical mount transom light (400065-1)
Here's the STERN LIGHT. But design is different.

a pair of vertical mount side lights (400080).

AND they also have a couple of interesting telescoping all round white fixtures
one is 24"/48". The other 34"/60" (400016-1). (Assume these are small powerboat allround whites - but if it is appropriate for us either one could be mounted in the pushpit line of stanchions, almost out of the way and ready to be extended for steaming.)

These are all 2nm Colreg and LED.
BUT, we don't find any data sheets, instructions, nothing, on these fixtures
So we don't know about any warranty
or EMI they might be emiting.
Would be nice to know if you use a handheld VHF.

They don't have any mast mounted stuff.

I've read where boats these days get robbed of their pricey LED lights.

In the McMasterCarr catalog you can find 18-8 tamper-resistant machine screws. 'Pin in head' Torx have a post in the middle so a regular torx driver cannot be inserted. And a spanner head which has two small separated holes that also requires a special bit. Page 3056 for the screws. Page 2821 for the screw drivers and Page 2810/11 for 1/4" hex shank bits for these special screws. The Torx would be my choice.
And the Torx pin-in-head hollow head bit is not likely to be found in any jerk's Leatherman.

I also called Sea Dog to inquire about the stern light. I'm not sure why but most LED nav light manufacturers seem to be quick to come out with a red/green version but forget completely about the white. Which also seems to be the case here. It may be that white light from LEDs is harder to produce and it may somewhat inhibit the design process.

At any rate the guy I talked to said he would at least get the ball rolling with his engineering dept. to see if they could come up with a solution.

Ebb there is a tech services guy named Mark Barnhart that may be able to give you an answer on the EMI emission radius on the units. His e-mail address is

continued from post #71
In that post I conjectured that the P.S. tests were slightly skewerd because they left out a major nav light manufacturer HELLA.
They left out AQUASIGNAL also!!!

I was cruising around the net trying for the last time to find somebody else horning in on the lucrative led navlight market. On the whimsical Jametown site they have a video box where we can view an equally uninformative guy at a boat show changing out the old quart sized AguaSignal incandescent masthead fixture for a spiffy led replacement.... He kind of waggles the old one out and shoves the new one into the same old base! Cool! But he doesn't identify the bright new shorty. Naturally we can't find the fixture in the scramble of nav lights in Jamestown's online catalog pages. They don't sell it !
Anyway, it is the S-32 Tri-Anchor. Shipstore has it for $645,77. But you can shell out $450/460 at pyacht if you have to have one. Hope it comes WITH a base! I'm tired of looking for prices.
The matching series side lights are in the $80 range.

OK, don't you think this is strange
that Practical Sailor also did NOT include this tri-color in its Feb 2010 comparison ratings.
But they did use "for comparison purposes" the 25w AquaSignal incandescent.....yeah,
it would be hard to ignore a nav light manufacturer that's been in business since 1868!
So why in hell is AquaSignal's led tri-color light NOT included?
Well maybe it's because it has a FOURTH all round white light on it!
And P.S. wasn't interested in THAT function.
OR interested in informing their readers (who like me want ALL the information they can get right now!) that that function was even available! BAH, HUMBUG.

google> agua signal Corporation
www. aguasignal.info/ecat/htdocs/index.php?id=209
(I'm going to assume that address won't come up, so try to type into google the title just as I have it. (Home Page - Support - FAQ.)
It is Q&A page where AquaSignal nureyevs all over itself telling us what and what not to do with their old masthead lanterns, nav lights and bulbs.
For us poor sods updating AquaSignal incandescent to led.

Think I'm putting this recent Practical Sailor test into the same category as their infamous marina ooze anchor test of years ago. Their credibility for me is walking the plank.
We assume that P.S. (our only marine product, no advert, testing source) has our interests foremost. Nav lights are of utmost importance and every aspect of what is in the market should be revealed by P.S. Afterall they are doing the 'scientific' study and collecting the data for us. We assume that P.S. is testing ALL COLREG APPROVED nav lights when we study their test results in the magazine. We aren't served by P.S. ignoring without comment manufacturers with long standing reputations. Or pretending that certain available options/features like the all round aren't of importance or interest.

Darrell Nicholson, the editor of P.S., called me this morning to scold me for an offensive sentence I have now deleted from a post above. In my defense I said it in jest. Most of the time it's obvious that their testing is without favor to one product. It's a tough sell. Especially single, new on the market non-comparison product reviews.
On his March 2010 'Rhumb Lines' editorial page he talks about blog posts, "Who's Lurking Behind Those Blog Posts?".
Last paragraph reads:
"Thankfully, Practical Sailor is not in the business of selling anything except what you have in your hand: reliable, forthright information based on independent, objective research and testing. We have no other interest than to provide our readers with the best available information on a wide rage of sailboats and sailing related products. If what you need is not in this month's issue, we've got it in our files, or we know where to find it. No need to wander the web, or wonder who to trust. Just email me at practicalsailor@belvoirpubs.com - or log on to www.practical-sailor.com, and you'll get a straight answer. But watch out for that diesel engine in the galley."
So P.S. is very sensitive to people like me who think they are legitimately looking deeper into whatever number of products tested in this tricolor case, and 'wandering the web' to do it. Sensistive to testing methods which should have some forthright reader review at times. Sensitive to just plain jerks and trouble-makers.
Darrell suggested I log on to his blog next time I had an issue, insidepracticalsailor.com.
He briefly explained the lengthy testing procedure and gathering of products to be tested: six months or more. The Hella omission and the AquaSignal omission were both because they were NOT on the market a half a year or more ago. Something maybe we couldn't know.
Told him I thought the editor should have mentioned these at the end of the test article before publication - and that another test/review was planned. ASAP.
I don't know what he told me about the allround whitelight omission. It bothers me that they without explanation did not review tricolors with allround lights. How can that just be ignored?

What does he mean about the "diesel engine in the galley"? Maybe he's refering to out of round, old fart curmudgeons like me. Bull in a china cabinet?

Still what we have in their expensive mag is what we see and read there.
But we should cut them some slack.
We have to take them at their word.

Understand that if we do get a comparison and a review of the absent led tricolors (AND ANCHOR LIGHTs) it will be at least 6 months from now.

You, wicked, wicked man, you Ebb!

I seems we are moving this thread in the direction of LED navigation lights again. So I'm gonna throw out the the fine, So. Pac. folks at www.bebi-electronics.com. You can't build a boat and then buy a masthead tri-color! That just wouldn't seem right...
