Hi Alan,

Thank you.

That is the way than Amel delivered Kimberlite.

I was just wondering id there was a better solution.

Re: Lithium Battery BMS

Hi Bob,  the helm switch has a 16 guage wire running to and from the Wakespeed wiring harness by the alternator. (They include good diagrams for the wiring harnesses)

I did not change the alternator wiring to the battery or the existing v-belt configuration.  For this reason I deliberately de-rated the alternator to 70% of max output. At this rating the highest output I have seen is 130 amps above 2000rpms. But I generally motor or motor sail at around 1700-1800 roms and the output is around 100 amps. I highly recommend de-rating the output like this to reduce alternator heat, wear on the bearings and belts as well as concern about the alternator wiring.  I'm not so worried about the wiring, as the rating is more about the voltage drop based on the length of the run than it is about overheating the wire in our situation. And the Wakespeed gets it's battery voltage measurement from the shunt at the battery not at the alternator and compensated based on that.

As my solar provide 80 to 100% of my daily needs and I can make up my deficit when running the generator for the water maker I leave the alternator switch in the "Float" or off position except when I deliberately want to add some charge while motoring. 

One other reason I don't use the alternator much during the day is that it will quickly push the battery voltage up to the point that the solar MPPT goes to Float which then reduces the yield that I get from the solar on that day.

Hope that info helps,

Regards, Daniel and Lori Carlson on sv BeBe, SM #387

Hi Dean,

The devil is always in the details .... that's usually what brings us undone in any endeavour.
I have thought very carefully about how we use our boat and what our requirements are (and I stress OUR requirements)
We live a simple life on board and our system is well balanced for our needs.
We like to run the generator to make water, heat the water, charge the batteries, occasionally run the washing machine - in the tropics we only run the Onan every 2 or 3 days.
The solar, and motoring (also charges the batteries, makes water and heats water), keeps us going in between.
 Our system seems very well balanced in terms of energy generation and consumption.
We easily manage it on a daily basis without discomfort.
So, given what seems to me to be an awful lot of added complexity going to an Li system, I think we'll stay with what we have.
I know that's not the currency of this thread, but I'm also pretty sure that there are a lot of sailors out there, like me, that were nearly seduced by the idea of Li batteries without realising the complexity of the management required.
As I said...the devil is in the details...and there a LOT of details with this Li business ....and a LOT of diverse opinions, which indicates to me that it is not well understood ....yet.
All the best

Hi Alan,
I agree with your concerns, and some of them were playing on my mind too. In 2019 I was going through the thought process and I made the decision that, for me, it was too early for Lithium.

I ordered a full set of new AGM's and battery balancers (you gave me some great advice about those at the time). I scheduled the delivery to coincide with my arrival back at Stella in Scotland. Then COVID struck and I was locked in Australia unable to fly back to the boat.

The company where I had ordered the new AGMs and balancers were very nice, I cancelled the order and they gave me a full refund.

I then bought an off-road caravan to do some travelling while trapped inside Australia, and it came fitted with a 200Ah Lithium battery, solar, inverter etc. Within a month of travelling I was hooked on Lithium (so to speak!).

It felt like I was getting more "usable" performance from a 200Ah Lithium battery than my 660Ah AGM bank on Stella. I believe the biggest factor is the efficiency of charging a Lithium battery compared to AGM. I'm sure you know the difference on paper, but it's a game-changer when you have the ability to pour energy back into your battery at the highest rate you can generate it, rather than watching your AGM charge rate slowly dwindle away, taking longer and longer to get to a full charge.

You get full use of your solar capacity and limit your generator run-times to shorter, higher-load more efficient cycles.

At the end of the day you need to be happy with the system you have on your boat, both from a performance and maintenance perspective. I can see that you think through the pros, cons and consequences in your decision-making process. I'm sure there are many many boat owners who don't do that but have gone ahead and installed drop-in Lithium batteries anyway. Time will tell whether we worry too much about the details!

HI Alan,

Do you have photos of how the halyard passes the spreader and how you tie it to the rail?

 

We also had it made long enough to pass it through a very large block and back to the electric winch so we could lift someone up to the top of the maim mast.

The previous owner of Elyse bent a few of those horns, I still have them.
In the 9 years we have owned Elyse we have never had a halyard wrap issue.
We have a spinnaker/gennaker halyard which we use with our gennaker.
It is always stored like this



with chafe protection on the upper shroud, it's tied tightly to the stbd rail aft of the mast.
It does get loose occasionally and needs to be tightened.
This is simple to keep an eye on.
Our Amel has a little notice next to the FOC (genoa) furling switch which says
"Attention aux drisses" meaning look out for the halyards, to avoid halyard wraps.
These are seamanship issues not design issues.

Agree.  I am sticking to AGM which are fairly simple and have served me well. 
Good fortune to those trialling new technology. I hope it becomes the norm in the future for s all. But just now I don’t have the technological knowledge to go that way. 
I follow with interest, but I’m sure there are many who should be confident in what they currently know and understand.

Fellow Amelians,

I have been following these Lithium threads with great interest as i really thought that with the cost of LiFePO4 batteries coming down, and the advent of "drop in" replacements for LA batteries, perhaps the time had come to seriously consider replacing our aging AGM bank with Lithium.

BUT, reading all this thread so far, I'm now no longer sure.

Our 660Ah AGM bank has performed well for 6 years - but we look after it really well - balancers on each battery string, never discharge to less than 85%, 600W of MPPT controlled solar., externally regulated 175A alternator (with a field disconnect switch to prevent over charging), always plugged in at the dock etc

Two concerns I had with Lithium were, the peak discharge rate required by the bow thruster and this sudden BMS disconnect issue...perhaps a hybrid AGM/Lithium bank could address those issues, but it all seems to be getting incredibly complex...and not very clear as to how to manage it all....especially when not on the boat.

By contrast our 660Ah bank of AGMs has none of these issues - nor do we have the listing issue pointed out by a few, caused by the lack of mass of the Lithium bank.
Our system is simple to manage and has worked really well over 6 years. It is only just now starting to show slightly reduced capacity - but there's still plenty.
Mind you, we're not great fans of aircon, nor are we interested in having an induction cooktop, so our needs are relatively modest by what seem to be modern standards / requirements.

Also, sailing in remote parts of the Pacific, as we are want to do, brings up the constant issue - what do you do if it goes wrong? and that applies to everything on the boat.
Of course if you never stray far from your home port, or frequent the Western hemisphere only - and have plenty of money - then maybe these things are not an issue.
My aim has always been to be able to keep the boat going, wherever we are - that is essential for us.

Maybe I'm just  considered an old-fashioned sailor these days - certainly approaching the "old" part - there was a time when I was "ahead of the curve" on all this stuff, but that seems to have changed !

So, while I am impressed with the technological advances spoken of here and admire the courage of these early adopters, I now think that when the time comes, I will probably replace my old AGMs with new AGMs - for another 6 years...

Re: Jib Furler wiring on the SM2K

Bill Kinney
 

Rick,

There were a couple different arrangements in the details of how Amel wired these, depending on when your boat was built.  You can find some of the details of the original wiring on our boat, and how we improved it here: https://fetchinketch.net/boat-projects/windlass-wiring/ 

In short... the power for the control circuit side comes from the breaker panel.  The actual power to the motor, does NOT go through the breaker panel. On our boat the genoa furler shared a 100A breaker in the forward cabin with the windlass.  Some of this was changed/improved/cleaned up with the SM2K. 

There are schematics for the wiring of the SM2K in the Files section of this board you might find helpful.

Jib Furler wiring on the SM2K

Rick Stanley
 

Question for everyone. Our jib furler was removed when we bought our boat, and we're curious if the original design had the furler wired to the helm  switch via the 24v breaker panel in the galley, was it wired directly from a breaker in the vberth to the helm bypassing the galley, or was it wired via both breakers (similar to the windlass setup). Any insight would be appreciated.

Thanks!!

Re: Amel lost its mast - D1?

James Alton
 

Bill,

   Thanks for your response and explanation of the potential problem.  I can see how if the haylard were to wrap on to the wire and be secured at the lower end that a lot of force could be applied to the wire.  I also found plenty of examples of forestays that failed on non Amel boats from the twisting that you described so this is a definite concern.    Thankfully no halyard wraps on Sueno so far.   On our boat only a few inches of the forestay wire is exposed below the swage fitting.  The short gap is there I believe to allow easy access to the forestay turnbuckle at the bottom and for servicing.  I am wondering about having a custom pc. of aluminum made up which would attach to the top of our Genoa extrusion and extend up onto the headstay swage fitting.  I think that this could prevent a haylard from ever wrapping anywhere on to the headstay wire itself.  The custom aluminum extrusion would need to be removed via bosun's chair to allow the system to be raised to adjust the turnbuckle etc. but that doesn't happen often.  I would gladly trade an occasional trip up the mast to remove the genoa extrusion extension for a reduction in the risk of headstay damage.  Recognizing that changes are seldom a good idea with an Amel, any thoughts on whether this might be a good or bad idea?

Best,

James Alton

James,

To explain:

When a halyard gets caught around the furling swivel, the swivel spins the halyard around the foil and usually eventually the rigging wire. If the end of the halyard is secured, these halyard wraps around the wire can get as tight as vice grips on the wire. With the swage fitting stationary, this twisting force will untwist the wire at the swage. Untwisted rigging wire loses all of its strength.

On our 54, we've used the gennaker, code 0 and Parasailor for thousands of miles. It attaches to the end of the bow roller and being non-factory, is probably more prone to issues. In our laziness, we've sometimes left it up, furled, and used the Genoa. I have never gotten even close to wrapping, so I don't buy the conclusion that a factory designed and installed option increases wrap rates. And if it does, Amel should retrofit it.

As Bill stated, he's seen halyard wraps twist the 10mm "horns" around the swivel. Bill - does that mean they are potentially protective and/or sacrificial?

We have two extra halyards permanently stored off the main, near the Genoa halyard and have not had any issues. But I am human and expect that it will happen at some point, probably in a 50 knot rainless squall that didn't show up on radar. Are there 40 A50s out there? It seems 5/40 = 12% of their sister ships having a potentially catastrophic failure is higher than should be accepted as "user error" and demands a fix.

It'll be interesting to see what Amel does to correct this. They already got a pie in the face since they highlighted this family on social media and of course, a Grand Large Rally participant here in French Polynesia, (this boat was allowed in the GL Rally despite not being a Grand Large boat), was well aware of the Amel that lost its mast island hopping in 15 knots. Another lost mast would be a "Polina Star III" level event, in my opinion. Not good for owners of any Amel, 50 or otherwise.

I’m one of at least five 50’s that I know of that damaged their forestay due to the light wind halyard either not being properly stored (ie. On the starboard side by the shrouds vs. on the bowsprit) or by leaving the halyard tension too slack (either stored on the bowsprit or with the sail up and furled)…

Re: Amel lost its mast - D1?

Sorry Justin, I don't understand what you mean by "more open".
When I look at your photo, that halyard on the block is exactly what I'm talking about.
If it's stowed the way it is in your photo, that is asking for problems.
In my opinion both lines should be taken over the spreader and secured aft of the mast the same as our photo.
You don't want halyards anywhere near the genoa forestay when furling the genoa.
The actual genoa halyard looks a bit sus to me too...it's too close to the rotating parts of the genoa furler.
That could cause problems if it wasn't bar tight....,is it actually the genoa halyard that caused your issue?

Re: Amel lost its mast - D1?

There is no device to open the angle between the genoa halyard and the forestay ?

Maybe it’s not necessary with the furler (profurl or facnor, i can’t remember), but on my (retrofitted) Reckmann, it’s specifically said there should be a 10°+ angle between the forestay and its halyard. 

Also, the Reckmann has a built-in resetable fuse that trips whenever it struggles with something. Admittedly resetting it requires a trip to the fore locker, which is annoying at best but that teaches you to be gentle with the system (and keep your halyards out of the way).

Hi Matt,

Thanks for your reply and suggestion, for some reason we have a J180 mount on our current alternator so that should help with the load.

I did a rough model of the alternator and was worried about the fitting, perhaps your configuration is different to ours, I was concerned about the angle brace of the engine mount.

Are you upgrading to serpentine belts too? John is suggesting a double crank pulley to allow both alternators to be serpentine belted.

I'd love to see some pictures of your setup before and after if it's not too much trouble.

Kind regards
