New is not always better, but sometimes it is .
I have a Nikon I purchased in 1969 ( and several newer ones including a Nikonos that is my boat camera) and I have a Nikon D-70 digital SLR I purchased in Feb of 2004 , I have shot one role of film since the D-70 arrived . Nikon got it right and I have felt no need to shoot film anymore , getting better prints from the digital .
Gasket material and dressing
Major marine catalogs think that real sailors don't need to make their own gaskets.
Auto supply has only engine related gasket sheet.
If you invent a company name for yourself (SV Bluenose, eg) I bet you can order from McMasterCarr. They have miles of foam and rubber sheet in all kinds of thickness in synthetic and natural rubber, much of it potential gasket material.
Much you can get in one foot squares, sometimes you have to get a square yard. Some of it is pricey, some very cheap.
High strength Weather Resist 40A (relatively compressible) EPDM rubber 12" X 12", $5.24. might be useful.
EPDM is an inexpensive outdoor rubber. It does not come closedcell foam by itself, but blended with other rubber.
Blends of neoprene,SBR, EPDM is the most common commercial closed cell gasket material with moderate resistance to fuels and weather. EPDM holds up better outside than neoprene (door gasket) but should not be in direct sunlight.
ECH, epichlorohydrin, is a closed cell rubber that will do moderately well with fuel and has excellent resistance to sunlight, heat, oxidation, weather, ozone. Gets my vote for all-round versatility.
Ionomer foam sheet reads good. Doesn't come thinner than 3/16" and they make buoys out of it. You want weather (Ozone, UV) resistant. Closed cell foam would give a firm more compressible gasket. But you have to get rubber that is rated for compression recovery. In other words, material that won't easily take a set and get tired while sealing a fitting. Don't want to compress any foam gasket more than 20% to 30%. MCMCarr has good charts and a bit disappointing explanations of uses.
And its a trip. You can start it on Page 3316!
HYLOMAR UNIVERSAL BLUE is a polyester-urethane gasket dressing that is a NON-SETTING compound you can use around the boat for other things you need to take apart later, and galvanic separation.
Idea is to fill the mini imperfections between the gasket and the fiberglass and/or metal surface. Better leak insurance than just depending on tightening up a dry gasket joint.
Believe it's distributed by Permatex and available in Permatex displays at the auto supply.
It's good for water and fuel and is NOT SILICONE based.
Don't have to scrape this dressing to get it off - easily removed with acetone.
As I see it, while synthetic gasket rubbers are getting longer lived, they still have to be replaced once in a while, especially electric fittings - so why not make it easy on ourselves.
Cut out thinner gaskets with X-acto knife and cardboard patterns. For round gaskets I just got a General gasket cutting tool that does inside and outside diameters at the same time. Some rubber like EPDM slithers around under pressure. You will notice in the online McMCarr catalog that some sheet is textured - this obviously is to create some tooth and to hold gasket dressing better for watertightness.
Foam stays put better for a seal. Dressing helps. You can get some dressing that acts like an adhesive and keeps the gasket from moving. May be necessary on freestanding fittings that capture the gasket only with fastening holes. Want the flange of the fitting to create a groove in the gasket, so some set is needed, that's why I lean toward closedcell foam material.

LED Replacement Lightbulbs for Navigation lights, etc.
Hey all:
I have ordered a selection of different LED replacement lightbulbs from 'Mastlight.com'. Their LED bulbs are 12v DC making them simply 'Plug & play' in most of our basic systems. No need to modify wriring or add gizmos.
I will be trying some different bulb types for the original Pearson factory navigation lights as well as interior lighting and steaming light. (My mast mounted steaming light is not an original fixture.)
I will post the results of my fit test and recommendations based on my results here once I receive the LEDs and try them out. I've been looking for this sort of product to complete my recently re-plated original nav light installation, so I am looking forward to getting these bulbs.
If there is interest in a group buy, let me know and I'll look into this. I had a nice chat with the guy that runs the shop and discussed the possibility of adding a custom page on his web site for Members of the Pearson Ariel/Commander association in order to make the search and purchase simpler & easier.
If you want to look around the website is: http://www.mastlight.com
The website is nicely set-up to search for the type of bulbs needed, and it also lists many replacement bulbs for the most common nav light fixtures out there.
Most importantly, this vendor has insight into the boating and has taken the specific marine use of his LEDs into account (including the right height for the typical fixtures' lens, and degree of visibility) something that most other LED vendors take for granted. (most are set-up to cater to the gaudy show-car/motorcycle, etc. markets...)
In the past, I've asked a few current commercial LED marine nav light manufacturers for help in my desire to retrofit my original fittings with an LED. Several of them stated that it was just impossible, and that I would be non-compliant with the Coast Guard and recommended that I buy their fancy fixtures... (most of which would look silly on a Commander!) even though the acknowledged the market demand for a simple replacement bulb...
Some FYI:
Are LED Bulbs approved by the USCG ?
Following the existing regulations, only the light housing (Fixture assembliess) are subject to an official approval (it must have the right color, be tinted in the mass and resist to ageing). Luminous sources must not get an agreement. However, lights must conform to the International Regulations of the IMO, which specifies the visibility distance of navigation lights.
- Since our lights' degrees-of-visibility are determined by actually blocking out the light from view, (note the wings on the stern light fixture for example) I think that the use of LEDs is perfectly fine in the case of our (or similar) fixtures. If a nav light relies on lens refraction for its precise degrees of visibility, then you might have a issue with the actual location of the light source. Not the case with our fixtures.
- It is recommended that you use COLORED LED bulbs as required for nav lights.(i.e. LEDs that emit RED / GREEN light as opposed to white light)
The reason that the colored LED bulbs are better is that the colored light emitted by the LED is more closely compatible with the tint of the glass /plastic filter thereby allowing MORE of the LED's available light to pass through the filters. (i.e. - they seem BRIGHTER).
As it turns out the original bulbs (incandecent) are: #90 Bulb bayonet type with opposing pins and two terminals on the bottom. Overall length 1-3/8 (Pictured below).
One Mfr number is: 90 12v 6CP - if you want to buy the incandecent version replacements.

LED bulb discount for the Pearson Ariel / Commander Assoc.
I have tested a number of different bulbs as an LED replacement for the original Pearson fixtures - with very good results, I am happy to say...
The vendor I've worked with is 'Mastlight.com'. If you want to place an order or just look around the website is: http://www.mastlight.com
:) :) :) :)
Hans, who operates the site has provided a COUPON CODE for use by Pearson Ariel /Commander owners; (or people lurking here!) Simply enter 'Pearson' in the space provided on the order form. This will apply a discount on your order.
Note that I get NO comissions, nor do I have ANY involvement with the vendor at all. I am simply providing this for Ariel /Commander owners reference because this vendor's products fit our fixtures nicely and he was willing to offer a discount for the group.
Here is some insight into the products I found work really well:
Original Pearson Navigation Lights:
For these fixtures I ordered RED and GREEN bulbs model 'BA15D Stacking D27LED Red' and 'BA15D Stacking D27LED Green'
*** Be sure to specify the 'Tall' version as these are about 1/4" taller and a much better fit in the fixture socket than the 'standard' version which sit a bit too low. You can see the 'tall' bulbs installed in my fixtures below in Picture #1
(See posts above for an explanation of the reasons why colored LEDs are more desirable than the pure white LEDs in Nav lights)
The standard height version of the bulb is pictured on the page (see the 27 LED version in the center of the page:
http://www.mastlight.com/BA15D.html
I found that these bulbs (which have a total of 27 LEDs integrated into the bulb) provide not only MORE light than the standard bulb, but they do so at all relevant angle ranges. (I was initially worried about the 45 degree visibility due to the LED arrangement, but it is not an issue when lit up...
The Stern Light:
I have a stern light that is not a Pearson original. I think it is relevant as it is almost identical to the Pearson original. (Mine came off a 1950's Chris-craft.) In any case, the space here is smaller compared to the Nav lights and the best fit for this was bulb Model 'BA15DD 12 LED White'.
You can see a picture of the bulb on the same page as the bulb above if you look to the bottom left of the page. You can see it installed in Picture #2.
The top LEDs are a bit on the high side inside this fixture, but overall, the LED bulb provides more light than the standard bulb. I had my doubts, but when I installed it and saw it on, I was very happy with the outcome.
Interior Lights:
I was VERY happy to find an LED product that works with the original little lamp shades used for our cabin lights.
The Bulb looks like a regular household bulb (maybe a tad smaller) but has 70 LEDs and it is 12V. It is slightly larger physically than the smallish 12V/15 watt bulbs I was using to date, but the do provide more light.
Additionally, they provide a similarly warm light as my incandescents. See Picture #3
I'll post a picture with the shade on. They provide a nice warm light for the cabin. In darkness, I found that even just ONE of these provided a nice amount of light for most purposes. TWO would fill my Commander's interior with plenty of light to read by...
I looked thru all the information Jim Reineck sent me but
I don't see anything that says if they sell parts or only complete units. Probably best to call him and ask. The phone number is 781-925-3312 or send him an e-mail at sales@bronzeblocks.com. Let us know what he says because the glass is chipped on my side lights and it would be grat to replace just that.
imPractical Sailor and LED
USCG regs dictate that sailboats under 65' have port and starboard side lights and a stern light.
The red and green sidelights are often shown in diagrams in the bow of the boat,
and we often see them mounted in a single fixture on the pulpit.
These lights and a stern light can be combined in a single lantern mounted on the mast head.
If we still want the lights on the bow, or separated on the cabin side and on the transom (or pushpit), Regs say that only one set can be on - NOT BOTH.
If we are coming into a marina at dusk and we have to switch running lights on, there are strong arguments for the deck level lights to be used because they can be seen better by others. And when we are moving they can be understood better in the dark by others. A masthead light imco in crowded waters is too tall and gives little information about who we are.
If we go with the side lights on the cabin, we would not have side lights (on) in the bow. One set or the other - altho it is unlikely we would have both.
If we are under power, which we may well be in order to have more control over the boat, Regs say we have become a powerboat. As soon as we get the motor going (even with sails up) we are under power.
If we are under power we have to show an all round WHITE light. The only place on a sailboat for an allround light is on the masthead. Under power we also will have the side lights on - but not the stern light.
This allround white light on the masthead is also our anchor light. Used as an anchor light, our side lights would be off.
LED 2nm
Practical Sailor in the 2010 Feb issue tests four led bulb replacements which might be of interest to those of us rennovating the old fixtures.
They also test three led tricolor masthead lights.
LOPOLIGHT (200-005) at about $700 with a five year warranty.
OGM (LXTA-12v) at $340 - two year warranty.
SIGNALMATE (2-nm Tri) $359 - five years.
None of these tricolors include the allround steaming/anchor light.
Notably absent is the HELLA led tri-color. Why would this manufacturer be ignored by PS boggles the mind - as these four are the only led tricolors with USCG approval that can be found, that I've found.
Not only leaving out a major player, but ignoring the white anchor/steaming light is really whacky.
However, the article redeems itself somewhat by carefully checking RFI (with a hand held VHF). Electricity reaching the semi-conductors, led's, causes EMI. This can screw up the VHF signal in the coils of the antenna mounted close to the led tricolor. The tr-color manufacturer has to shield his product from other electronics at the masthead.
They tested the bulbs too for interference along with the tricolors by holding the handheld VHF radio at close distances to the lights.
Suffice to say only LOPOLIGHT had no RFI at 0 inches.
SIGNALMATE got RFI at 10". Assuming the test procedure is good, there just is no way I'd get this fixture and mount a VHF antenna next to it.
The website advertises the tricolor is fully shielded. Now we know - thanks to P.S.
P.S. also checked out by distance observation whether the red/green overlapped. They also graded how green the green was, Led greens often have a blue cast. And blue is a law-enforcement color. Lopo and the Lunasea bulb got the nod for the greenest green.
I'm attracted to the HELLA NaviLED Trio Masthead / Anchor Light - $340 - with a seven year warranty.
Data sheet, drawings, measurements, installation anst all available online.
"Electromagnetic Compatability (EMC) This LED lamp is an electronic device. The electrical circuits contain components that suppress possible interference, both emission as well as susceptability. to the limits prescribed in EN60945".
We didn't get the skinny from Practical Sailor on this.
HELLA also have some nice side and stern lights at $93 each. Defender has them $10 cheaper.
They don't tell what any fixture or lens is made from (polycarbonate?). If plastic then 7 years warranty is a stretch in southern climes.
A half dozen international certifications including USCG. So the green must be OK.
Just info and all of it my opinion.
Why on water would anybody with an active sailboat go with a plain tricolor?
How would you later add the allround white, if you wanted to? Led's are already too expensive!
on the all round steaming cum anchor light
C'pete,
The Hella lantern has the tri-light in the prescribed separations: green - red - and white stern running light - with a seen from dead ahead separation of the red and green. A slight blank space.
It also has, SEPARATE from the tri-color combo, an ALL ROUND WHITE, on top of the combo. It is a separate light but in the same lantern. This light would NEVER be turned on while the tri-color was being used. And viceversa.
Being an all round light, and UNABSTRUCTED by mast or sails,
I have seen, have downloaded, diagrams like yours above here that show this all round white (USCG Regs) USED AS A STEAMING LIGHT ON A SAILBOAT (but with sails not rigged) when the motor is running.
Imco it would be 'more' legal' than a half mast steaming light that would have 1/3, at least. of the all round requirement obstructed by the mast it is mounted on.
And in a twilight ballet of getting the boat into its berth without running into something, no reg could possibly care if the rags are up or furled. Never know, tho.
Your series of graphics don't show this. And since the tri-color option is relatively new (what, 20 years by now?) the Coast Guard may not have their diagrams up to date. Besides the all round white steaming/anchor light may be stuck in some internal committee and is left in its fuzzy status for decades to come.
Perhaps by sailor use the added FOURTH light on the masthead of a sailboat will become written into regulation. It seems to be allowed by inference and some 'quasi-official' diagrams.
The all round white is already wired on some lanterns as a STROBE light. On the highseas, day or night, with an approaching freighter, switching the strobe on to get attention might save your and your boat's butt.
Regs might someday be rewritten to include emergency scenarios like this as emergencies. Using the strobe to get the attention on the bridge of a cargo freighter. Fat Chance! Radio contact with the freighter would call off any rescue effort or USCG notification that assitence was not needed. If that is the case.
The all round anchor light from a practical aspect has to be stacked on the masthead above or below the tricolor if we have one. Cruisers forums often mention that they can recognize their boat at night - when away from it - by their all round led.
This anchor light can also be found with a PV Sunset On/Sunrise Off feature.
Practical Sailor led nav light ratings
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.:rolleyes:
"Badges! What badges? I don't got to show you no stinkin' badges"
Ebb we all know how thorough your research is, you don't have to take any c*&p from PS!

Stern light parts available to anyone who needs them...
I bought a new stern light for my commander of which I only plan to use the base and the new glass dome from. I will be using my old top piece and plan to have it rechromed.
So I have the new top piece I purchased, my old base and cracked glass dome, and Commander Pete sent me his old base and top piece to offer to anyone that needs it also. The glass dome can be purchased new for either of these old lights. I should also mention that both of the old bases need a new socket installed in them.
Well, that did not take long...
All I have left is one of the base sections. Free to anyone that wants it...
