Congratulations on Makemo!

 

I had no idea that the generator run time was that much – wow! Solar and Lithium would transform your world for sure!

Hello Billy,
we acquired 4 months ago Makemo, Amel 55 nº1 and we are experiencing all the fixtures.
today with one fridge and one freezer, we are consuming about 200Ah/day at the mooring and much more while sailing with everything on. We only have 2x 185w solar panels on our davitts producing in the West Indies between 1.2 and 1.5kwh in January (8am till 5pm more or less).
Therefore we are using the genset everyday min 2.5 h up to 4h.
We are looking for increasing our solar capacity replacing ours panels with 2x 370 or 440w new panels located at the  same place.
it should deliver 2x mini representing 2-3 of our consumption at the mooring.
our batteries are AGM 660Ah (24v).
we would also like to put flexi panels in the hard top but we have not yet identified a good way to put the cables.
Happy to exchange your project when defined.
regards

Should I just put a patch of fibre glass on top of the affected area inside the boat, or should I do something also at the outside (by the rubrail)? I am attaching some pictures.

Re: Cracked Forestay Chainplate

Ellen Cahill
 

Thank you very much for the detailed explanation. The fracture was not in fact on a weld but rather on a bend. Even if it was bent under proper heat tratments I suspect that it still caused stress concentrators to occur in this area. The fracture surface looks very similar indeed to yours Bill, mostly dull and grainy with signs of slow crack propagation. 

So careful inspection and regular washing seems to be the best preventative solution before replacing parts. 


Re: How much Solar?

Justin Maguire
 

Has anyone experienced the 50 with the lithium? 

My new 50..  which because of covid I won’t set foot on until April 1 when she arrives in the US... has 800ah of 24v mastervolt lithium (which I could almost not believe). 

I’ve got the new gn-espace induction stove...

She currently has 600watts of solar on the davits, and 575 on the hard top... I could go up to 1000 on the davits by wanted to see if this setup would work before making the davits into a full blown flight deck 🤣

Anyway.. I’m dying to see what the real world usage will be and how often I’ll have to run the gen set... ideally this setup should provide for a very independent and luxurious setup but real world vs. theory are always different...

Anyone out there have the lithium on the 50 (or the 60 for that matter as it’s the same)?

Scott - your numbers make me sooper optimistic...

Aching to see my new baby in person...

Hello Billy, I just increased my solar to 2 @ 335w panels on a stern arch (670w total). In January in Antigua I'm averaging just under 3kw per day but it is increasing slightly as the days get longer. Location around the island impacts cloud cover! (Currently ranging from 2.5kW to 3.6KW)

We typically consume about 140AH (3.7KW) at anchor. So I have a daily deficit that ranges from 5AH to 40AH. 

I have 400 AH of LiFePo4, so I can now go extended time without running the genset. Basically I run the genset when I want to run the watermaker and then add 30-60amps of charging to load the generator up to about 19-21 amps and add some charge to the batteries.

This is so much better than when I was running the generator daily to keep the batteries charged.

The downside of my new situation is that I used to also keep the water heater hot with the daily generator runs. Now I need to rewire my 230v side so that I can periodically run the water heater from the inverter.

Hope that helps with and additional data point.

Neil my new GELs die, hopefully in 4 or 5 years.

I suspect 750W will be enough in a sunny location at anchor to avoid running the generator most days. Our boat drops from 100% to 70% overnight or about 200aH. So, at anchor, I figure just under 400aH a day or about 5kw. I dont know if that's high or now. Our boat is pretty stock as fitted.
If I'm moving then I will need to run the genset no matter what because of radar, auto pilot etc, I suspect.

Re: Cracked Forestay Chainplate

Matt Salatino
 

It’s likely that the “Y” had to be welded.
It’s very difficult to maintain the metallurgy of stainless, the proper mix of chromium, nickel, etc, through the welding process. Putting that welded chainplate on the bow, constantly washed by salt water, is asking for trouble. No wonder they changed the design. Good move.

Re: How much Solar?

We have 3 345w lg panels. In a good summer day we can see 7kw. Max watts peaks at 1150w to 1200w.
This is with Firefly batteries.  If they top off the batteries early in the morning I will switch on the water heater or 1 air-conditioning unit. 
We are very pleased with the solar system, genset hours are reduced by 70%.

Re: How much Solar?

Karen Smith
 

Billy,

Our usage is pretty consistent, an average of between 200 and 250 W while at anchor, and 325W or a bit more when underway.  This is with two chest freezers, and the front opening galley fridge which are the big usage hogs.  This is separate from the power needed for the water maker or laundry.  We have a smaller battery bank of 464 Amp-hrs, and the typical consumption we see over night is MUCH less than what you are seeing.  Typically, our SOC drops about 15 to 18% overnight, significantly less than 100 Amp-hrs.  Our typical overall usage while at anchor for 24 hours is about 180 to 200 Amp-hrs with about half this amount being supplied by our panels.  All those numbers shift a bit depending on weather and temperature.

Our solar panels rate out at about 630W, and we typically run the generator every other day.

Re: How much Solar?

Mark McGovern
 

Billy,

This thread has some great "real world" solar data in it: https://amelyachtowners.groups.io/g/main/topic/32721714  

Pay particular attention to the posts by Scott from Tengah (Amel 54) and Porter of Ibis (also an Amel 54).

To summarize, Tengah has 960 Watts of solar and was able to average ~5400 Wh/day into it's house bank over the course of a month.  Note, Tengah has an LiFePo4 battery bank.  Ibis has a similar size solar array at 945 Watts but it has an AGM battery bank.  Porter doesn't give an exact amount of Wh/day put into his house bank but looking at the image he posted of his solar data, it appears to be less than half the amount that Tengah is able to put in.  The difference is mainly due to the significantly reduced charge acceptance rate of Lead Acid vs LFP batteries at higher SOCs.

So while adding a third solar panel will help, it won't likely eliminate the need for you to run the generator every day.  At least not until you change out your batteries from lead acid to something with a much higher charge acceptance rate at high states of charge.

Re: Cracked Forestay Chainplate

Karen Smith
 

Ellen,

This kind of failure is not unusual with stainless steel, and can be seen on many stainless parts in saltwater service, especially those under cyclical loads just like your headstay chainplate.

We had this happen with one of our jib cars, and if I zoom in close on your photo, I am pretty sure the same scenario presents itself.  https://fetchinketch.net/2019/07/26/failure-analysis/

The other place I have seen this happen on our boat is in the shackles on the boom outhaul cars. The usual assumption is they break because of overloading, when they actually have been greatly weakened by nearly invisible crevice corrosion before the failure.

The shape of this piece and its location on your boat means that it is very hard to actually give it a really effective visual inspection, even if it was removed from the boat and in hand.

The best way to prevent it is to be sure than any welding is first class, by somebody who really knows stainless steel, and it is fully electropolished afterwards so there are no pits or cracks for corrosion to get started.  Then careful inspection on a regular basis with a magnifier looking for incipient cracks.

Re: Onan ballbearing check and valves values

Stephan Regulinski
 

Oliver H. et al.,

I have a Onan model MDKAL, vintage 2000, so twenty years old now. My Operator's Manual, which has the maintenance schedule, says:



Outer race rotation is the probable result of a frozen or damaged bearing. Deteriorating grease is the likely precursor to a frozen or damaged bearing. But you can't inspect the grease, since this is a sealed bearing, so the only thing you can look for is evidence that the bearing is failing.

That said, this thread suggests to me that failure of this bearing is very rare. If it was common, you'd expect the factory engineers to be quicker with explainations, you'd think Onan techs would be familiar with replacing it; and you'd expect the Amel community to have some war stories about it (like we have for the outhaul gearbox or raw water hydrant plumbing). 

Based on all this, I suspect the maintenance schedule on this part is too frequent. My manual says to change every five years, the Onan tech in Panama City who adjusted the valve lash (and wouldn't do the bearing) said every 2000 hours, which for me would stretch that to eight years. 

My Onan is at just over 5000 hours. I will replace the bearing this year and, if the off bearing shows no evidence of damage or excessive wear, will increase the interval to 3000 hours. It's possible that the original bearing is still in the genset (I've no maintenance logs from the first two owners). 

With an upgrade in solar panels (and decrease in genset use), it'll last the rest of my natural life. If not, I'll let you know.

Cracked Forestay Chainplate

Ellen Cahill
 

We recently cross the Atlantic in Saol Nua, a 1986 Mango. Just before sitting down to breakfast to mark our halfway point we spotted a very significant break in our forestay chainplate. With 1200nm to go I was extremely anxious but also very grateful we spotted it before the mast came down. We decided to furl in the Genoa for the remainder of the journey and using two spare bottle screws secured the forestay to the two bow cleats. We also attached the inner forestay.  We checked the condition of the plate every 2 hours for the remainder of the journey. 

On the mango the chainplate is an upsidedown 'Y'. One half had severed completely and a crack had initiated in the other. I inspected the rigging before we departed but I suspect evidence of a crack may have been on the inside of the plate. We had 20knots on the aft quarter and fairly calm seas so it pointed to an issue existing prior to our departure.

Thankfully we made it will the rig intact and have since replaced the chainplate. I climb the mast and carefully check the rig before any passage over 24hours but now, with the boat that bit older I'll be keeping an eye on the chainplates! 

Any else ever seen this happen?

Amel 55 Fwd shower valve leaking

Billy Newport
 

I noticed yesterday that the fwd shower is dripping when turned off. It looks like a Paffoni brand shower mixer, the other taps in the bathrooms are similar brand.

Is there a rebuild kit for these? New washer or something? How do I remove the panel to get behind the shower fittings to service them. I can see screws on the top and bottom of the aft shower tap "box" but the fwd one has nothing obvious.
