Bill,

I kid!  The inner 13 year old in me couldn't resist the softball you threw at us. 

I have no idea what they are worth but you will likely find many Amel owners who would love to buy them from you.  If we didn't have a pretty good set of them already aboard Cara, I would be one of them.  You should also let the Amel Facebook group know that you have these available as well.

Re: Solar panels stainless steel mounted vs soft panels

Bill Kinney
 

Another perspective:  

We have 630 Watts of solar panels on an arch that supply roughly half of our electrical needs. A good reliable, efficient system that greatly reduces our genset runtime. 

We really, really REALLY appreciate the ability to fold down our bimini/dodger at a moments notice, and we do--a lot.  On a cloudy day, at night on passage to watch the stars, for visibility while maneuvering in close quarters, for communication while anchoring, while fishing.  For this reason we would never encumber our dodger with solar panels.

Re: Solar panels stainless steel mounted vs soft panels

I have 600 watts (two series pairs) in hard panels on the stern arch that give a maximum of 16A at 24v on sunny days.  I also have 250W of soft panels on the Bimini which produce a maximum of 3A in bright sun (in Maine now),but in less than ideal conditions, they hardly produce anything.  I recommend that you stick with hard panels.  I'm thinking of replacing them with more hard panels if I can figure out how to mount them above the Bimini.

Volvo TMD22 Engine Mounts

Bill Kinney
 

Another lesson learned:  Do NOT wait to replace your engine mounts. Bad things can happen. Engine vibration and noise creeps up on you, very slowly.  You don't notice that it is a little bit worse today than it was last month.  And next month is worse again.

During our time with Harmonie we had never replaced the mounts on our TMD22, but I suspected it might be time when I did finally notice the engine vibrations increasing a bit.  Today, I changed them out. It wasn't as difficult a job as I feared, one full day of hard work did the trick, mostly. What's left is cleaning up and painting things that have gotten a bit rough looking. I have some video footage I'll share of the process, but I thought I'd give you an advance visual of how bad things were. These are hydraulic mounts.  They are full of a viscous oil that damps vibration.  Three of the four mounts had lost ALL of their oil. The one on the right is a new mount, the one on the left had just been removed.  The oil chamber was completely blown out.



I suspect that the failure of the engine mounts lead to increased vibration and misalignment which likely lead to, or at least contributed to, the failure of the rear seal of our transmission last year.  On the ZF25M transmissions replacing the rear seal requires a full disassembly of the ENTIRE unit, and is not practical. By the time you buy all the seals, gaskets, bearings, and other parts that should be replaced, a new transmission is the more economical answer.  

So, two lessons:  
  1. Changing the mounts is not that hard, with a bit of creativity, and inexpensive tools, you can lift, pull, push, and shove the engine without outside assistance.  
  2. Change them BEFORE they get this bad!
I don't know how old these were where we bought Harmonie, but I am putting these on a 5 year replacement schedule, sooner if I even THINK I notice an issue.

We installed the LSG Vetas waterlock, part of the repower, happy with the performance. You can have different diameter on the entry/exit. Moved to the fuel tank side,  removed a little bit of foam around the lsg for a nice fit between the engine frame.

Re: Solar panels stainless steel mounted vs soft panels

Alan Leslie
 

Paul, 
You don't mention anything about what kind of regulator you use (used) with your solar setup, if you used one at all.
You imply that panels in series are not efficient, but I'm guessing your 2 x 18V (nominal 12V) panels in series were connected directly to the battery bank, and no that is not efficient.
If you now have 36V panels, wired them in series and used a MPPT type controller/regulator, then that is very efficient.
But if you just wired them in parallel directly to the battery and don't have a MPPT conttroller/regulator you will be missing out on a lot.

Cheers
Alan

I am in the process of restoring a 1975 Meltem. I will be documenting the process in a website I am building. More like archeology than restoration, carefully removing everything that can be removed, cleaning, repairing and mounting back.


The good news for all of you, Amel owners: you can expect a long, long life from your Amel. Well worth your investment!


After 46 years, the construction is impeccable (hull, stratification, bulkheads, hardware attachments) with no major cracks. The Meltem is still rock solid. And so are the subsequent yachts (Maramu, Super Maramu and others).


We have 1,500 liters of fresh water in the keel: no gelcoat cracks, keel bolts intact.


We have 850 liters of diesel in two stainless steel tanks. As the old folks say, they don't make them like that anymore.


Everything used by Amel craftsmen has stood the test of time: varnished wood, custom stainless steel hardware,  cabinet doors, kitchen sink or bathroom features (storage cabinets, first aid cabinets, shower heads, shower pan). The African mahogany used (for the table, the bunks, the lee boards etc) is in perfect shape.


Goiots ports, aluminum hatches: all impeccable (just new gaskets) and not leaking.


We tore apart the electrical and plumbing systems: all stainless bolts and screws were first quality and easy to remove. The hoses (I forgot the name of the French company making them) were still impeccable.


The hydraulic steering is not leaking and is perfect.


The frames holding the engine (it was upgraded to a massive 125hp Yanmar by the previous owner) are rock solid.


Amel yard had that sense of perfection only found with the early Mac computers (as Steve Job used to say, there is pride in that perfectly hidden screw no consumer  will ever see). Every panel is easy to remove, every piece of wood still fits perfectly, every door closes. And you still have that homey feeling of warm quarters and curved doors.


The bad news: as Bill Rouse loves to say, every problem or failure we encountered was due to a modification by a boatyard (most of them are mere handymen). 


We had the misfortune to have work done at a yard in Port Napoleon over last winter. Just about everything they touched (plumbing, electrical, carpentry) created troubles immediately or we found the problems before it was too late. 


Leaks were patched up pouring epoxy, plywood repairs were epoxied to the hull (I assumed it is faster than using bolts), cheap plastic Chinese shower heads we broke the first night. As the yard said “we don’t repair here, we change”. If you own an Amel stay away from that place then!


I jumped into the trash to recover the old bronze shower heads, screwed them back with a new o ring et voila!


I crawled into deep lockers to investigate: the yard did not bother pulling the old wires. They just drilled new holes, ran wires and hoses with nothing to protect from chafing! So different from the Amel yard where every hole through plywood of GRP was coated to prevent water damage and fitted with anti chafing material.


Lessons: don’t let yards mess up your Amel. If you let them do it, they’ll drill more holes in the hull and will install inferior products simply because it is what their wholesaler has in stock. 


Follow strictly Bill Rouse’s suggestions and take things into your own hands. If you do, you will still enjoy your Amel thirty years from now (if not you, someone else will) :-)

A54 Fridge gas strut and other gas struts

David Crisp
 

In the spirit of sharing info' and sources.....

This summer I replaced the gas strut of our galley work top fridge/freezer as the original one had worn out and didn't support the lid.  I sourced a replacement from Metrol in Northampton, UK. Specifically this one: https://motioncontrol.metrol.com/variable-force-stainless-steel-gas-strut-ns-ss-v-8-150.html    I wanted to use the existing anchor points (rather than the ones supplied) so had to drill out the holes in the ends of the struts an extra millimetre, easy enough.  Excellent result. :-)
A copy of the invoice is attached so you can reference part numbers.

The nice thing about these guys is you can build up a custom design so for those folks I've seen asking about other struts such as for the engine compartment I think this could be a solution.

They ship globally.

Hope this is of help.

Re: Solar panels stainless steel mounted vs soft panels

Alex Comer-Crook
 

From most of the data and tests I have seen over recent years rigid panels will give you at least a 30% real-world output advantage for the same advertised output vs. flexible panels - potentially more. This is assuming they are both high quality brand names (sunpower, solbien etc.) and have similar charge controller arrangements etc.

This is almost entirely due to superior heat dissipation of rigid panels that are generally on an arch instead of being glued down on a hard surface or attached to hot bimini fabric. Flexible panels often also have a protective layer on top to make them walkable which decreases efficiency even more. My general thoughts are that if you want to go the solar route and run most things you should have an arch with rigid panels primarily and then add a few flexible panels just for supplementary power if required. MPPT charge controllers are relatively cheap so an additional array is often worth it long term to avoid shading issues. You should split your arrays/sections between items that would shade them (i.e your mast) and then you can run the sections in series if you need to. Depending on budget it might be worthwhile upgrading older 12v/18v panels as most panels these days are higher voltage so you don't have to worry as much about running them in series to charge 24v.

Flexible panels are very useful and have their place but if you want to be a liveaboard and run most things off solar then I don't think you can get away without 2-3 high output rigid panels on an arch.

Scott, same Bowman cooler on Yanmar SMs and 54 D3s.

It is very important to inspect the end of the cooler nearest the sea chest. This is where debris will accumulate and reduce water flow. According to Bowman the number 1 failure of the Bowman Cooler is the overtightening of the boot hose clamps on each end. The metal is soft enough that a overtightened hose clamp will squeeze the tubes closed.

 

Here is a short story for many Amel owners. I had a client who had purchased my Amel Book and 24/7 Support. After about 5 years he decided to sell his Amel. When it was being surveyed the surveyor insisted on running the engine at WOT, the Onan, the water maker, and 3 Air Conditioners. The engine overheated. The surveyor's conclusion was that the Amel sea chest and manifolds were inadequate. My client called and was very distressed. I suggested to him that the Bowman oil cooler had debris inside the boot nearest to the sea chest. Nobody agreed with me and thousands were spent. The sea trial was done again under the same circumstances. The engine overheated again. This time the client removed the large clamp on the end of the Boman Cooler nearest the sea chest and found it full of debris. In 5 years he had never done this, although I recommended it and it is in my book. The moral of this story is easy to figure out. The page from my book is below.

Thank you for sharing your experience. We removed and had all of the heat exchangers professionally cleaned in 2018. However, it is not possible to identify wear. Therefore I’d like to order a couple of the heat exchangers and replace ours and have one as spare. It is hard to read the part number on the cooler, without removing it.

 

Does anyone know if all A54s used the same part number too, or are there different parts for different hull numbers?

Subject: [Special] [AmelYachtOwners] Bowman DC60-XCC Transmission Oil Cooler Failure; ZF Hurth ZF 25; Yanmar 4JH3-HTE #lessons #lessons

 

In the spirit of Pat from Shenanigans "Lessons Learned" post a few week's back I thought I would share what I learned when my Bowman DC60-XCC oil cooler failed while motoring up the coast of Maine a few days ago.  Thankfully, we caught the failure relatively early in large part due to the fact that when cruising in Maine you have to remain hyper-aware at all times because of the lobster pots that are literally all over the place including in marked channels and anchorages. Because of that, both my wife and I were in the cockpit doing nothing but looking out for lobster pots and calling out their positions to whomever was at the helm. There were no podcasts, no music, no book reading, no headphone, just hyper-vigilance with two people, 4 eyes, and 4 ears on watch at all times. 

The first symptom we noticed was what sounded like a slight misfire of the engine.  It sounded like the RPM increased ever so slightly for just a second.  It was just a "blip" and was not large enough to actually even register on the tachometer.  After hearing it a few times, a minute or so apart, I asked my wife if she was hearing it. She said she was. My first thought was a clogged fuel filter despite the fact that my last fuel fill ups were from fairly busy harbors in Annapolis, MD and Onset, Massachusetts and that we had only ~60 hours on the Racor filter.  In addition, the RPMs of the engine seemed to increase not decrease like I would expect from fuel starvation from a clogged fuel filter.  In any case, I switched over to the second Racor but the occasional engine “blip” did not go away. In fact it got more frequent and it actually started to register on the tachometer just barely.  I put my head over the side to take a look at the engine exhaust.  I did not see any white or black smoke coming out of the engine exhaust.  However, I did see an oil slick trailing behind us the likes of which I have never seen before.  My immediate thought was that the engine oil cooler had failed and was leaking engine oil into the raw water system.  We had no choice but to shut the engine down ASAP.  There was only 6-7 knots of wind directly behind us but we also had a bit of favorable current so we just put out the main sail, turned off the engine and called Towboat US.  We are not at all familiar with this area and we did not see any decent anchorages looking at the charts. We were only 2 nm from our destination of Belfast, Maine and the Towboat captain said it would take him about an hour to meet us at the entrance to the harbor.  So we sailed at 1.5-2 knots with just the Main and met the Towboat captain at the entrance to the harbor where he towed us the last mile to our mooring ball where we still sit right now waiting for our replacement oil cooler to arrive from the UK.

 

Once we were safely moored, I went down to the engine room to check the oil in the Yanmar.  It was perfect.  Not a drop appeared to be missing.  After a brief “wtf?” moment, I checked the transmission dipstick.  The fluid level did not even register on the dipstick at all.  However, I could see that there was some ATF left in the transmission case.  That was a bit of a relief but not much.

 

All of this happened on a Saturday and I do not carry a spare oil cooler so I would have to wait until Monday to order a replacement.  First thing Monday morning I started to call all of the USA dealers for Bowman marine products listed on Bowman’s website.  Of those who actually answered the phone, none of them had the DC60-XCC in stock or even just the DC60 (oil cooler with no end caps). One actually told me that he didn't think DC60-XCC was a valid Bowman part number. I said “I’m looking at their catalog online right now.  It is.”

 

I then called Bowman in the UK and asked if they knew anyone in the USA who might have one of these in stock and they hesitated and said the only one who might have one is Tradewinds Power Corporation.  When I had previously called Tradewinds Power Corporation they said "our computer system is down right now" so we will need to call you back.  They never did.  

Luckily, I had also asked Bowman who in the UK would definitely have them in stock and would ship to the USA.  Without hesitation, they told me that Lancing Marine will definitely have it and they ship around the world.  So I called Lancing Marine (https://www.lancingmarine.com/) and had a wonderful experience buying from them.  Not only were their prices the lowest by far that I had seen anywhere online (79 GBP/~109 USD including new couplers) but the ordering experience was fantastic despite it being phone order only.  The person I spoke to also obviously knows these transmissions well.  His name was Mike and I'm pretty sure he is the owner and founder of the company - founded in 1970!  He gave me his opinion on the state of my transmission (he thinks it’s probably fine) and advice on how to test it to see even before the replacement cooler arrives.  On top of all that, despite it being about 3pm their time when I called, the coolers (I ordered a spare) shipped out the same day.  Last, he said that if I do need to get the transmission rebuilt, that he would highly recommend a company in the lower Chesapeake Bay called Transatlantic Diesels. He says that they know these ZF transmissions better than anyone and he has done business with them for years.  It was really just a great overall buying experience that seems to be so rare in these days of anonymous Amazon purchases.

 

The moral of the story is that for ~$109 plus shipping and an hour of my time I should have replaced the transmission oil cooler PROACTIVELY soon after I bought the boat back in July 2017.  Especially given that I did not know the age of this critical part.  Or I should have replaced one of four times that I have replaced the transmission fluid.  At the bare minimum, I should have had a spare oil cooler already on board.  The engine, and I assume the oil cooler, just surpassed the 2000 hour mark.  Researching this site after the fact I found at least two other SM owners who had the same failure at around the 2000 hour mark. Both, I believe, lost their transmissions.  Hopefully, I have not. I will know in a few days time.

 

So in the spirit of the #lessonslearned, don’t be like me.  If you are not sure how old your transmission oil cooler is, replace it.  If it’s approaching 2000 hours, replace it.  At a minimum, get yourself a spare oil cooler.  And if you can’t find it locally, get it from the nice people at Lancing Marine in the UK so that we all have at least one place in the world that keeps these things in stock.

No it does not, and most 100 w panel's are 36 cell 18 v panels ( nominal 12 v)  you need to have them in serie to charge 24 v, very inefficient. We replaced or 2x 100 watt panels with 2x150 w 36 v panels. Now in August I get around 0,6 kWh from the two. From one 400 w panel I got 2.5 kWh. I'm on Last Palmas Canary Islands. During ideal conditions in June I got 0,8 kWh resp 3.0 kWh from the above. I have 2 rail mounted panels 2x180 w now in a marina they are titled up vertically a very poor way to keep them but lack of space force me to have them that way.. They outperform the soft on the Bimini giving CA 0,85 kWh

Paul, I did not realize that you lost efficiency or  output by connecting the panels in series. I am far from an electrical engineer ,I wish I were,it would make owning an Amel easier. I may be better off replacing my three, 8 yr. old 17v panels ( in series) with three 36v panels . I am going bald scratching my head ,I had a full head of thick fur when I bought this boat.
Thanks,
Pat

No it does not, and most 100 w panel's are 36 cell 18 v panels ( nominal 12 v)  you need to have them in serie to charge 24 v, very inefficient. We replaced or 2x 100 watt panels with 2x150 w 36 v panels. Now in August I get around 0,6 kWh from the two. From one 400 w panel I got 2.5 kWh. I'm on Last Palmas Canary Islands. During ideal conditions in June I got 0,8 kWh resp 3.0 kWh from the above. I have 2 rail mounted panels 2x180 w now in a marina they are titled up vertically a very poor way to keep them but lack of space force me to have them that way.. They outperform the soft on the Bimini giving CA 0,85 kWh
