Re: LiFePO4 Batteries, what they can do for you.

Thank you nick - my goal with 1200watts of solar and 800ah of lithium was to run the gene set once a week... 

This would let me make water and do the wash, as well as give the gen set enough run time not to have its own issues from too little use!

Re: Spinnaker pole strut mast fitting ball joint replacement? #replacement

A few years ago I was sailing N in the Gulf Stream in 20kts from astern.  In the middle of the night with no warning (it was a moonless night with no lightning observed) we were suddenly in 35+ kts from 40d off the starboard stern.  The seas rapidly grew from 5-6 ft to 8-10 ft.  I turned directly downwind and furled the headsails together to about 10%.  But before I could muster the crew and get the poles down, we rolled and caught the tip of the port pole in the water.  It shattered the forward guy block, and the pole came whipping back alongside the dodger. No damage there, but potentially an even worse problem than we had.

The problem was a thunder storm that must have formed right over us, or just didn't have any lightning.  That was before I got my new Radar, and I didn't use it at night unless I saw a specific need.

So now I take the poles down at night, and run the radar at night.  In any choppy seas over 4-5 ft, I raise the end of the poles a couple of feet above horizontal.

Re: Spinnaker pole strut mast fitting ball joint replacement? #replacement

 

Here is a snippet from my book. 

Pole ends were made by FranceSpar, now www.SpaceCraft.fr, also in the US www.sparcraft-us.com. I am not sure if that company made the entire system for Amel. Amel recently made a new set of poles for a SM for a client of mine. Amel may be the best place to source that ball end because when I searched www.sparcraft-us.com I could not find this part. If you do not hear from SAV@... in a few days, call them at 33  5 46 55 17 31. 

I assume that you sent a photo with your request and that your request asked for availability and price...if not, it should have.

Re: Spinnaker pole strut mast fitting ball joint replacement? #replacement

Danny and Yvonne SIMMS
 

Hi Folks,

This message concerns me. It comes after Delos reported on a near disaster while sailing downwind in gale force winds. As in this case they had the headsail poled out. Both vessels had bad outcomes with gear breakage. The Amel handbook recommends limiting these systems to 20 knots true wind. Down wind in big seas vessels, even Amels can yaw and swing, particularly if there is a big sea running. 

In both these cases when the wind wrong sided the sail serious damage occurred. In conjunction with this damage severe sideways forces would have been applied to the mast. Neither damaged the mast but in my opinion the strong possibility was there.

Of such errors are disasters made.

However these were both wind events. Consider the loading had the boat rolled at the same time as a big sea came up along side and the pole had dipped in the water. Delos was doing over 15 knots at times. We need to be aware of the risks of long poles fixed out at right angles to the boat and take them in in strong winds.

Just my opinion

Regards

Danny

Re: vetus coupling removal

Herbert Lackner
 

Danny,  the Setup on the SN is a different than the SM. No disk brake, but the big pulley for the shaft alternator. I had to realign the engine to get rid of the vibrations and found no other way than to remove the coupling and align it with the special tool. Also the connection to the gearbox is a little bit different. How did you do the alignment without the special tool and the coupling connected? I think it is not possible to do that on the SN without removing the coupling.  After 1 hour tapping it started to move for about 1 mm, then it was a mm by mm job. This was one of the very rare moments I would have been selling KALI MERA to anyone who walked by...

Ian, I did the realignment in 2019, after getting the coupling off it was an easy job, but if I had made the special tool a little bit longer it would have been better, because the setup on the SN is different from the SM. The connection to the gearbox an KALI MERA is the same as on OCEAN HOBO.  After cleaning the shaft and the coupling it slides on and off easy.  After realigning the vibrations are almost gone, but in some conditions (big waves from the side) it is still not perfect.  Please let me know if the change of the rubber tube helped on your boat. Have you been able to move the c-drive with your hands - is there any movement if you pull?  I tried it on KALI MERA and there is no movement at all, but I am not sure if I should open the seal next time when she is on the hard and check that. Greetings to Linda, I hope you are all fine

Hello Justin,

This is unbelievable, but true.

With 1200 watts of solar the only reason you would NEED to run the generator is NO sun.  But, you may WANT to run the generator because you want to run the AC for more that 6 or 7 hours a day.   Let's just say this - you probably wouldn't miss your genset much if you took off for a two week trip with a inop genset.

That's pretty spectacular Ken...  imagine if you bought that third battery you have space for - 900 Amps is a LOT of juice.  These Lithium batteries are going to change the way we all cruise.   I like the fact that yours are 24V batteries and you don't need to go Series/Parallel (although under the covers presumably they are just like 12V batteries are a series of cells).  I am curious about the BMS what happens when a cell goes bad.  I imagine it takes down the whole 24V battery pack - perhaps some more justification to Admiral Z for getting the third!  :-).

Hi Eric

 

Thanks a lot for your information. I’m currently working on it by pushing with your concept and at the same time pulling with a puller on the other side.

But still very tough job. I managed to move it 1mm but still no big progress. Will work on it mm by mm  (4/100 inch).

 

Why you used threaded rod instead of new bolts with same size?

Hi Ruedi,

Yes, you must cut the existing bolts.

You use threaded rod and nylocks to replace the bolts.

When you have the disk off , have a machine shop cut a few thousands of an inch off  the interior of the dick mounting hole.

I hope these pictures help.

@Eric, is saw in an old treat from 2019 you did it by pushing with screws/bolts from the back but I cannot undo the existing screw’s. I suppose you saw it away and used new 10mm bolts for the tool.

 

I’ll make some photos when I’m done and send it to the forum.

Re: vetus coupling removal

Ruedi,

I don’t know the configuration of the 54 but on the 53 you cannot remove the bolt without cutting it – therefore you cannot put a bolt back in.

Possibly the 54 is different.

Here is more information about the set up, and how I maintain my batteries.  Hope it helps answer some questions about LiFePO4 batteries.

Re: vetus coupling removal

Hi Herbert and others,

Just remember that everything you do to the shaft coming out of the C drive you are doing to the C drive. The shaft goes through a lip seal to a bearing to bevel gears. Every hammer blow hits those bevel gears and the bearings. The heat applied gets to the lip seal. Think about it. 

And I ask why. By the simple expedient of cutting the heads off the bolts holding the vetus coupling together I avoided the need to remove the c drive connection. I then replaced those bolts with a high tensile rod threaded each end and two nuts.

In separate operations at different times I have: replaced the vetus rubber bushes, replaced the gear box, changed the engine and changed the engine mounts. None of these required the removal of the coupling off the c drive shaft

The first of these was the rubber bushes. I tried to get the c drive connection off, and like you all found it very hard. Because there was a simple, non damaging alternative I wasn't prepared to subject my c drive to abuse. 

Regards

Danny

Hi Ruedi,

heating, spraying, puller, nothing worked.

I remember it took 5 hours using a heavy hammer and a piece of wood:  tapping, hammering, then brute force ...

LiFePO4 Batteries, what they can do for you.

Ken Powers SV Aquarius
 

Hello All,

I have uploaded a video, and think it has a lot of useful information.  Just got back to Aquarius, had to do the 10 day quarantine to get back into Thailand, but the Thai Government jjust raised quarantine time back to 14 days for those arriving now.  Made it just in time....  As I type this message, it's 3:50AM here in Thailand, and I am almost 15 hours into my battery capacity test after a year with Lithium Valley LiFePO4 batteries.  I bought 600AH at 24V of Lithium Valley LiFePO4 Batteries.  I charged the batteries fully with my Victron 3000/70 Inverter/Charger to 28.4V, then unplugged the shore power connection at 1PM yesterday afternoon.  As I am on the hard, I went down stairs and unplugged Aquarius from the power connection.  The AC power is now supplied by the Victron 3000/70 Inverter/Charger.  I turned on my portable AC unit that draws about 35Amps, and now almost 15 hours later I am still running the AC.  I have pulled over 490AH out of the batteries and currently sitting at 25.98V while pulling 33.4A.  In 3 hours my test will be complete, after I have pulled over 500AH from the batteries.  My alarm is set, we will see just how well these batteries perform after a year on Aquarius.

Here is more information about the set up, and how I maintain my batteries.  Hope it helps answer some questions about LiFePO4 batteries.

Hi Eric

 

Thanks a lot for your information. I’m currently working on it by pushing with your concept and at the same time pulling with a puller on the other side.

But still very tough job. I managed to move it 1mm but still no big progress. Will work on it mm by mm  (4/100 inch).

 

Why you used threaded rod instead of new bolts with same size?

 

Best regards

Ruedi,

Hi Ruedi,

Yes, you must cut the existing bolts.

You use threaded rod and nylocks to replace the bolts.

When you have the disk off , have a machine shop cut a few thousands of an inch off  the interior of the dick mounting hole.

I hope these pictures help.

Hi Amelias and Eric

 

I tried to remove the Vetus coupling from the shaft and I was not able to remove it even not with a strong puller and heat.

Maybe someone out there has another great Idea?

 

@Eric, is saw in an old treat from 2019 you did it by pushing with screws/bolts from the back but I cannot undo the existing screw’s. I suppose you saw it away and used new 10mm bolts for the tool.

 

I’ll make some photos when I’m done and send it to the forum.

 

Thanks for advice and best regards

Hi,

Here is the photo. Once you have it apart have a machine shop open up the hole a few thousands of an inch.

today I tried to align the engine and the c-drive. unfortunately I was not able to remove the vetus coupling from the shaft, tried it also with a puller but without success.  Are there any tricks, special tools,... how this can be done? I remember Eric uploaded a foto showing the tool he made for that, but could not find it. any help welcome
