thanks Joel,
Yes your absolutely correct about the fishing boats.  The marina also has many derelict boats and live-aboards on vessels well past their prime.  I will pursue the galvanic isolator.  I wan't sure about the grease coming out of the bottom of the gearbox, but I'm one to investigate until my confidence builds.  it turns out there were "dry" pockets within the gearbox, and the upper bearings had significant rust and no longer turned smoothly.

Thanks for the history and advice

Re: [Amel Yacht Owners] electrolysis on jib furling gearbox?

As I recall, Moss landing has a great number of commercial fishing boats. A friend of mine who surveys a lot of commercial fishing boats once told me that the two most neglected things on these workhorse vessels are the grounding systems and the ground tackle. As fishing boats are either working or on the dock, the later factor is understandable. The first one, not so much. I would recommend you get a reputable marine electrician to install a galvanic isolater. The DC system on all Amel boats is a fully floating/full earth return system just like almost every metal boat afloat. The AC system has its own peculiarities and if your electrician condemns it, have him call Bill Rouse 832-380-4970 who will tell him why it is the way it is, and why it must stay that way. As a caution, I know of several boats where the propeller and/or the stainless gridwork inside of the rudder were destroyed over the period of a few days by improper modifications to the electrical systems.

                                                                                                                                                                                

The grease you saw beneath your jib furler is entirely normal. You will note that the headstay passes through the furler assembly. When first rigged at Amel or later by a knowledgeable rigger, the aluminum headfoil on the headstay is packed with grease to lubricate the headfoil from the harder stainless steel headstay. When you no longer see grease beneath the jib furler is more of a cause for alarm.

 

As a bit of history, I sold that boat when brand new to a good friend of mine who gave it his wife’s nickname, TOWOWIE. It’s a long story…  Anyway, I was fortunate to have the exclusive use of the boat for a bit more than a year as my Amel demonstration/boat show boat after it crossed the Atlantic. I later sold it to an interesting

couple from Reno who named it LIEBLING, thankfully , after also considering burdening it with the name MUNCHWINKLE. I could not be clever enough to make this up…

 

It was later sold to another couple who I presume sold it to you if you are the forth owner. It is a great boat that seemed to burn out anchor light bulbs faster than any other Amel Super Maramu’s I have known.

 

Good luck and enjoy your LA QUERIDA .

 

All The Best, Joel

Hello and welcome to the group;

 

Sorry to not address you by your name but I did not see your name in the e-mail.

 

I cannot comment on the source of your particular issue. However if you are connected to shore power in a marina or harbor without a galvanic isolator, you are exposing the boat to a high risk of electrolysis depending on your particular location, wiring and boats surrounding you.

 

I would highly recommend the installation of a galvanic isolator to prevent creating an unintended electrical circuit. Olivier recommended the install on our 54 during the survey. The installation is fairly straight forward and it took us a couple of hours to get done.

Greetings and Happy New Year,

I’m new to the group having purchased “Liebling” SM hull #207 In June 2017.  Now she is “La Querida” berthed in Moss Landing, California.

Over the last several months I noticed something like grease dripping out from the jib furling gearbox and finally dismantled it last weekend.  In general it was in reasonable shape for a 20 year old gearbox.  However the aluminum  disc on the out put shaft showed considerable pitting which I interpret as electrolysis.  On my particular box, the aluminum is in contact with a bronze or brass bushing.  I did some reading on line and was quite alarmed to learn that neighboring boats and poor grounding of the marina shore power apparently can accelerate electrolysis on a well designed and maintained boat such as our Amels.  So two questions:

  1. Has anyone else experienced this electrolysis on the aluminum disc on top of the gearbox?  (or is mine indicative of a bigger problem)
  2. I briefly investigated galvanic isolators as protection for poorly grounded shore power.  Is this worthwhile?

Thanks in advance.

BTW our plans are to cruise to Mexicos west coast after retirement in about 3 years.  Saludos a todas!


Re: Coppercoat?

Ian Park
 

We re-applied Coppercoat. It is easy to put on, but continuous stirring is required to ensure the copper particles don’t sink to the bottom of the tray - you have to roller it on. It’s water based epoxy so easy to clean up. Yes, we get green slime, but you can scrub it off with a plan scrubber or a large scraper - you couldn’t do that with ablative paint.
At haul out it just requires a jet wash a quick sand with 800 grit an launch.
Not everyone’s choice but we love it - no more painting the hull for 10 years.

JPG,


   You mentioned removing the balsa.  So the cabin sides of the SM are cored with balsa as opposed to being just one solid laminate?  It would be nice to know the construction since window replacement is on my short list as well. Actually if there is core in there I am going to move it to the top of the list!   I used to use cut down  allen wrenches shaped and sharpened to form cutting edges (in place of the bent nail) to cut out a core but found a better solution.  You can get small saw blades for your dremel and these make core removal fast and you can also use the blades to abrade the inside edges of the glass to give your epoxy a good bond.  It’s a bit of a pain but you can extract essentially all of the water that entered the holes by using vacuum. You can use the same basic supplies and set up that is normally used for vacuum bagging,  just add a good water separator to protect your pump.  It is always better to get the water out before sealing things up if at all possible.  Kept completely dry, balsa lasts pretty much forever, good stuff.

   I hope that you are having a great time in the Bahamas!

Best,

Hello Herbert,


I encountered the same problem on my SM when I recaulked the side windows.  

First option: The screws are not long enough to traverse into the wood trim on the inside of the cabin.  Procure various length M6 screws and drill through to the inside.  Pack with lots of Sikaflex and finish the work with a nice looking ball nut on the wood trim.  

Other option: this is what I did.  Make the hole bigger, but no larger in diameter than the width of the SS strip (about 14 MM if memory serves me right), clean out the wet balsa with a nail bent to 90 degrees on the end of your drill, fill with epoxy then drill a pilot hole where needed and reuse the original hardware.

Good luck,

Re: Generator charging question

svperegrinus@yahoo.com
 

Our solar chargers by Genasun are not properly adjustable to the voltages required by Trojan for our AGM batteries.  So we disconnect solar when on shorepower to prevent over-voltage charging of full batteries.

We routinely turn on both battery chargers as follows:

(1) When charging from the generator.
(2) When we will have shore power for only one day or two.

Evidently after one hour or less the batteries charge at less than 100 A, and at this point it makes no difference whether you have one or both chargers on.  So we routinely turn one off.

Cheers,

All our chargers, including solar, are set for the same absorption and float voltages...I think you might be asking for trouble of you have them set differently...especially if you are running more than one at a time.

Re: Inverter/Charger wiring advise

John Clark
 

and now Bill K some more inverter/charger talk:

I opened up the genset control head and traced the out the wiring.  There is an earth/bond connection but is is between the two field coils.  This means that the green/yellow wires are always 115v different than the hot(brown) or neutral(blue).  

The genset has been this way since installation many years ago, so it is apparently doing no harm.  Since as you pointed out the genset is connected to the bonding system, I will leave the AC safety jumper in place and see how it looks when I fire her up.  

The inverter will have two connections to the bonding system, one is "pass through" from the AC power  supplied by the generator or shore power.  The second is the chassis ground that the unit will connect to the AC output only when the inverter is supplying power.

Re: Bonding wire question

John Clark
 

That is a good question, and not easy to answer.  I will take a look and see if I can run each to ground....that's a pun by the way.  

I will be spending some quality time in the ER installing the new inverter/charger this week after the rain passes so I will likely be opening up several of the wire runs to add the new cable. It will be a good opportunity to trace the wires.

Re: Generator charging question

John Clark
 

I too was instructed to run both chargers from the generator, also  start the 40A then after a minute start the 30A,  and when on SP use the 30A alone.  

  I noticed that my 40A is set for a higher float voltage, just a tad under 28v, while the 30A floats at 26.7v.  I have AGMs and the 26.7 sounds more in line with a long term float.

Dear Amelians,

I had to buy a new PCB board for my ONAN generator which finally seems to work fine for more than just a couple days...

I kept my old board, hoping to find someone who knows how to analyze faults and eventually repair this rather expensive part and then keep it as a spare.

So does anyone of you know somebody who could do this work?

Bonding wire question

Bill & Judy Rouse <yahoogroups@...>
 

I haven't asked a question is a long time...so here goes.

This question is about the large soldered bundle of bonding wires located above the gray water sump.

Has anyone counted and traced these wires...and can tell me:
  1. How many wires are joined at this bundle on their boat? This will vary based on production year, options, and possibly owner-modifications.
  2. What each wire protects and where it terminates?
​I believe it will help everyone to have this information.

Re: [Amel Yacht Owners] Coppercoat?

Mark Erdos
 

Part of the argument for Copper Coat is their claim you save money not having to haul the boat as often. However, you will still need to haul an Amel to do drive maintenance. Therefore, not much of a savings when you think about it.

 

Also, the procedure to apply Copper Coat is not something an everyday boat yard does often or knows how to do. It is not as easy to apply as paint.

 

My 2 cents

 

 

With best regards,

Re: Coppercoat?

greatketch@...
 

Miles,

Coppercoat seems to be one of those things that sailors love to argue over--almost as much as which anchor is best. Some people think it is great stuff, others are very disappointed.  Some differences in opinion seem to be varying expectations, and others seem to come from using it in different environments. 

I have one piece of data, for your "what it is worth" pile...  The previous owners of Harmonie put on Coppercoat. Within a year they had it stripped off and went back to a conventional ablative paint.  I do not have any other information about the whys or wherefores on the changes, so it's not really a lot of help...

I have never been able to assemble data that convinced me one way or the other. It clearly works for some people, and not for others. I am sure that SOME of the failure stories are due to bad application, but I am also sure that not ALL of them are.
