Re: Firefly batteries

Bill Kinney
 

Paul,

We have a full set of Firefly batteries, and love them.  We periodically do a complete discharge to dead flat, and a rapid recharge as Firefly recommends as a "restoration charge."  Every time we we have done this we carefully monitor the amount of power discharged.  Each time the amount of power they have delivered has been above the original specification sheet value, and it is still the same as the day we installed them. The last I looked, it seemed that Firefly bumped up the rated specification of the batteries from 116A-hr to 120A-hr which is more in line with what we measure. We take good care of them, but while out on the hook, we certainly do not bring them fully charged every day.  They don't care.

For the way we use our boat, they give us all the benefit that a set of Lithiums would, at a significant discount.  They never have had any trouble with powering the bow thruster, or high loads out of the inverter.  At a steady 50 amp draw the voltage stays remarkably steady all the way down to about 15% SOC.

Some issues to watch for:

Firefly recommends that the batteries be charged at between 0.2 and 0.5C My recollection of a 54 is that you have 12 G31 batteries.  That would give you a bank of 720 A-hrs.  Charging that large a back at a rate of 0.2*720 = 144 Amps might be a challenge with a standard charging setup.  Our older SM has a 480 A-hr battery bank.  We have a DC generator that outputs 150 amps at 24 volts, so it fits well within the minimums recommended.  If you can't reach the recommended minimums, they request you talk to their technical staff for an alternative procedure.  I don't know what this is, but  it might be worth investigating up front if it might be an issue for you.

Early in their production run Firefly had difficulty with the occasional battery developing a shorted cell.  Left undetected, this can bring down the entire bank  in short order because of charge imbalances.  It is not a problem unique to these batteries, any type of lead acid battery can have this problem, but it seemed Firefly had more than their fair share.  We had this happen to us, and Firefly was 100% helpful and completely took care of us under warrantee. Our current monitoring system doesn't allow this to happen without us knowing about it very quickly.

We have 615W of solar. Our normal daily power usage is about 3kW-hrs, and solar can make about half this. During our normal charging cycle while at anchor in good weather we end up in the morning at about 75% SOC.  Over a sunny day, the solar panels bring the batteries up to about 90%.  The next morning, the batteries drop to about 60-65% SOC.  The generator starts in the early morning, runs for 80 to 90 minutes, and brings the bank up to 93% where it shuts down, and the solar panels have the bank at 100% by 3PM.  And the same two day cycle repeats.

We find we get excellent utilization for the power available from our solar panels, and the generator runs most of its time at high load, where it is most efficient.  For us, minimizing expensive generator run time is important.

We have looked very hard, and sharpened our pencils a lot, and for us we just don't see a benefit to Li batteries that justify the higher costs.  But every boat works differently, and everybody has different needs.

Re: Firefly batteries

Paul, I had them installed several years ago and they all failed to deliver for me after a couple of years. The issue was always voltage drop under high loads like bow thrusters, etc. Eventually, I could not keep them charged properly - I had low-voltage alarms almost every night.
I do not want to dissuade you from taking that route, as I know others have used them successfully.
Maybe I am a unique situation with higher than average loads, but I am just reporting my bad experience. I ditched them for LiFePO4 batteries 2 years ago. Without any doubt, the lithiums have been excellent, with the most significant feature being (to me) that they retain a constant voltage throughout the discharge cycle.
I will never return to any type of lead-acid batteries. Keep in mind that Fireflys are a type of lead-acid battery, albeit with the added benefit of carbon foam.
Hope that gives you my perspective.

Installed ours in May 2019. I give them a thumbs up. It's comforting to know that they can be in a partial SOC without causing significant damage or drastically shortening their lifespan. Will be interesting to see how long they actually do last, cycling pretty much every day. They're technically an AGM battery, carbon foam AGM. Ideally they get topped up to 100% once a week. And should get a periodic "restoration charge", which we've only done a couple times because it's only really feasible with shore power. We weren't quite ready for a switch to lithium so we went with these.

   Many thanks for the inspiration to look into rebuilding our D4.  I hope to remove and inspect it over the weekend.    Would you happen to know if service parts are still available for these older D4 heaters?  

   BTW, there seem to be quite a few Sharki's in the Preveza Greece area, really nice boats!

Hi Paul,  we installed firefly batteries 2 years ago,  happy with them,  I have experience with wet cell batteries,  firefly are easier to maintain.  I can't compare them with gels or agm styles. 
We have a large frame 175amp alternator,  1kw solar, 5kw quattro,  we only use the genset if we have limited sunshine. 
Can run 1 aircon during the day on a hot summer day.

Re: Air con circulating pump

Brent Cameron
 

It’s not hard to find relays that can be energized by 240VAC signals and that can switch 24VDC devices. You just want to be sure that the switching capacity isn’t exceeded (eg trying to use a 10Amp relay to control a 20Amp motor).  You also need to understand if the circuit is normally open or normally closed (or the relay is energized to close contacts to start/run the motor or vis versa). My guess would be Normally Open which also means the relay can be depowered when not needed and will use no power when the motor isn’t running).   You also want to be sure that the relay can handle the start currents of the motor as they can be considerably higher than the run current.

The 240v is AC and the 24v is DC, but I’m not sure that makes a difference.

Re: Retractable bow thruster maintenance on a Sharki

Davi Rozgonyi
 

I did this service after neglecting it for only 3 years. Not much visible corrosion but I dam near ruined the tube using the tool. My fault, I thought a small car jack could press it out after nothing moved for a few days. Nope. Cracked my tube, which is fragile. Loads of penetrant (which drops onto the shaft limiting the effectiveness of the tool), lots of gentle tapping, lots of patience (days or weeks of it). NO HEAT. After you do it, drop it once a season, regrease the splines, then she'll be tight forever. If you mess up your tube, maude can make you a new one for about 3400 euros by the way. Thankfully I had an amazing glasser who repaired mine good as new.... Good luck! Defo the hardest job I've had so far in 4 years onboard Wake.

Hey Ben,

 

We visited that boat this summer, it seemed indeed to be in good shape for its age but in our opinion the fact that the standing rigging, the engine, the sails, the electronics, and some of the running rigging, although serviceable were all due (age or hours wise) for an upgrade wasn’t priced in we decided to pass.

 

We ended up buying a younger Maramu with a replaced engine, more recent sails, and the Nirvana mast in mast furlers for less. 

 

The current boat inventory might be different so take it with a grain of salt 

 

 

We hired Bill Rouse and he would tell you to not overpay for that boat and to get it surveyed by Olivier Beaute as you are in France.

 

 

Good Luck

Thank you for all your reply.
Bill Rouse's pre-purchase consulting package seems like an amazing idea. Unfortunately it seems like he is no longer offering this service for Amel's older than 1988 (please correct me if I'm wrong).
Here is a link to a photo album with photos of the maramu. A mixed bag of photos we took during our first visit and the photos provided by the broker.

And here is the listing from the broker (in French though):
https://www.annoncesbateau.com/bateau/1981-amel-maramu-5016467/

What I could see is the following:
the lining inside is coming unglue in places (aesthetic)
the gooseneck of the mizzen is coming loose (critical)
the varnish near ONE window is pilling off (aesthetic)
I was wondering about the bolts for the winch and the stoppers showing up on top of the lining 
The engine has nearly 7000h and is original 

Couldn't find much else to complain about but I didn't take everything apart either.. planning on doing that during the next visit (which is now scheduled for Saturday).

I also know that in 2000 it went trough an extensive anti-osmosis treatment from a professional company (traitement curatif par pelage du gelcoat ... pealing of the gelcoat?)
In 2010, the mast was removed to fix an issue of electrolysis at the bottom of the mast (between the mast and the deck of the boat)
The in-mast furling was added in 2004
Fridge replaced in 2003
One blackwater tank added in 2010

That's about all I know at this stage.

 i absolutely second Jim’s advice below, we did this 6 weeks ago on Liesse, our Santorin to install the aftermarket silicone seals which seem to be working very well btw.  It took me 3 full days to get it to break loose, even though once down it did not look that corroded.  I do not think I would have been able to drop the shaft without the press made and sold by Amel.  Even so it had a tendency to want to slip down the shaft making you think you were making progress, this occurring perhaps because I was quite cautious about not wanting to damage the carbon fibre shaft by over tightening and found lining the contact service with sand paper glued to the tool,improved it’s grip. Took nearly a full can of penetrating oil, endless tapping, many attempts with the press and tremendous persistence plus no shortage of expletives, but it’s quite gratifying when it lets loose.  Be sure and have it well supported so it doesn’t fall to the ground, a line through the foot seemed to work pretty well.  Good luck. 

 Best, Dave

Paul,

   Congratulations on your new Sharki!  The bow thruster on my Maramu was also stuck in a similar fashion when we bought our boat.  I would urge patience in dealing with this problem rather than using a lot of force.  I used a rawhide  (non metal,) hammer to tap the interface while spraying lots of PB Blaster.  Letting the penetrant soak and coming back to it to try again the next day.  It took about 5 days but finally there was some movement and finally removal with no damage.  Once all surfaces were cleaned up and greased future removals require someone below the bow thruster to catch it when the last bolt is removed.  I remove the bow thruster, change the oil and seals at each haulout, it is so easy to do now.  These just need regular servicing.  Best of luck to you.

Subject: [AmelYachtOwners] Retractable bow thruster maintenance on a Sharki

Hola from Spain,

This summer my wife and took over an Amel Sharki, so happy to be part of the wonderful group now :-). Unfortunately the bow thruster has no propeller so we got a new one from Maud of Amel as well as a service kit. The assembly requires separating the lower part with the gearbox and the upper part with the motor. Somehow there is a lot of corrosion and the parts have grown together. Is there a trick to separate them again? Does anyone have similar experiences? Does anybody has disassembled the motor and might have some tipps?

Best regards, 
Paul
