Hello Annesophie,

I seem to remember that you had works done at a marina in this place. Can you please confirm and if so give me more info because I am thinking that Malta is a bad place for selling Amels and I am thinking of having the boat moved up to France by a passage crew as I have terminal cancer.

I think it only referred to as Muriatic Acid in the US. Other places will refer to it as Hydrochloric acid which is a solution of hydrogen chloride (HCl) in water.

Hello Bill et al,

 

I just spent the day at Onan UK learning about the MDKAL.  Another Amel owner was there… he had done the organising for this course.

 

If one wishes to do the cleaning himself, the instructor said that well diluted “brick cleaner” would do the trick in 10 minutes.

 

Remove the heat exchanger and immerse the unit in the above solution.  Rinse well then reinstall the component.

 

Basta.

Re: Satellite communication - Fleetbroadband 150

webercardio@...
 

I changed to Inmarsat FleetBroadband Pre-Paid Small vessel Plan. So I activate my fleetbroadband 150 only  the weeks, when I am on the  boat. I charge  via internet , my provider is   GlobalTelesatCommunications  in England ( www.globaltelesat.co.uk ) but I also contaced a company in US.
I choose this company, because  you can  ad for a few money the REDPORT-Optimizer - very usefull to make a protection between SAT-phone and  computer . You will find more informations on web ....
I only pay once activation fee,  buy a voucher  for 60 days, use it , renew , prolong or loose it.
You may make your calculations with the rates  on the website.
So I use all my units until I leave the boat. The next weeks, there is no  charge. Activate via internet for
the next holiday works well, you  buy a new  voucher, no extra activation fee.

Selling Underwater Camera Kit - Never Used!

Hi there.  I am selling an Intova IC600 underwater camera kit with an entire variety of accessories.  I bought in July 2010 per a friend's recommendation when we were sailing around the world on our Amel but for logistical reasons it never made it to the boat.  So has never been used.  Listed on Ebay if you are interested.  I thought someone on this board might be interested in it.  Thank you.

  Kent,
your prop and transmission are protected by the zincs on the rudder, only as long as they are connected. When measuring the resistance (ohms) between the prop and the rudder zincs, you should not find more than 10 ohms. If you find more, the connection is bad (damaged wire somewhere in the vessel), if you find much more, this means there is no more connection.If you can't find where the wire is damaged/cut, you should just install a new one, going from the engine cradle to the rudder shaft quadrant. And then check that every item that is supposed to be bonded, is really bonded (check the resistance again).In the engine room, you should also find a big connection between the cradle and the C-drive (otherwise, as the C-drive is mounted on rubber mounts, it may be isolated from the cradle).I guess you already know that the ballast must be connected too (thanks to the famous copper strap down in the bilge).
Good luck.

  Hi Kent,
no need for a wire in the water as, you mentioned it, the bonding circuit is already in contact with water.However, in case of a power leak coming from the boat itself, you could perform the same tests with the vessel on the hard...The main question is: is there any connection between the ground circuit (yellow and green wires) and any negative or positive (12V or 24V)?
Have a good day.

  Good morning Pat and every happy reader,
the informations in the previous message (from Eric) are very good and cover most of the problem.I would add the following:-sacrificial anodes that quickly go are most probably subject to an unusual power leak but first question: were Pat's anodes made out of zinc? In fresh waters, metal boats use magnesium anodes, because fresh water is less conductive and magnesium is more sensitive (than zinc).In salt water, magnesium will disappear very quickly.First conclusion: Pat, you should replace your anodes quickly with zinc anodes. how do you know it is zinc? Zinc is approximately 4 times heavier than magnesium. The discs (2) you have on your rudder should weigh around 1.4 kg (3 pounds) each.-electric leaks often come from the board circuits: a new Equipment (not original) where negative is connected to the device body (Inside, you don't see it): check the conductivity (meter on the ohm position) between negative and body. Your Wind generator could be like that.This can also be a faulty connection: a loose wire of a navigation light touching the guardrail or mast.This can even be carbon brush dust creating a connection between a furler motor and the mast.
The method to search for a possible leak is:-is there any voltage between +24V and ground, -24V and ground, +12V and ground, -12V and ground. Do this test in the engine room as you have there all the power sources available and connect one side of your meter on the engine's steel cradle. If you find a voltage, you should confirm using a small bulb (1 watt). If the light shows, it tells you on which circuit is the leak.For instance if you find a voltage between the ground (engine's cradle) and the 24V negative, this means there is 24V positive connected to the ground. Then check every 24V item with breaker ON and then OFF.
This search is a very long job, but should start with everything new on board, or every recent job performed.But remember the leak could come from usual wear.
The last Super Maramus and all AMEL vessels built since, have been equipped with a leak test device. However, this concerns only the +24V and -24V.
The leaks coming through shared earth ground circuits (in marinas) are more and more frequent: don't keep you shore power cable connected when you're away from the boat. Even if you turn off the breaker on the power supply (on dock), your ground cable is still connected: REMOVE THE CABLE from the shore outlet.
One last thing: when one of my clients asks me, I advise to have these checks performed by a skilled electrician...
Good luck.

  Whenever different metals are placed in a conductive liquid you create a battery. If you connect these pieces of metal together, current will flow. The current will be removing metal from one of the metal pieces = "electrolysis". If this piece is the zinc in your flashlight battery that is good, but if one of the pieces is your propeller it is bad.The zincs you use on a boat are called "Sacrificial Anodes". Zinc is used because it has a higher voltage in the water so the current will be more inclined to flow from it than from your propeller. To complete the electrical circuit, the zincs must be connected to the items they are intended to protect. Usually this is no problem because the zinc is bolted right to the shaft or underwater housing. Non metal boats will usually have a copper bonding wire inside that connects all the underwater metal items together so they all share the protection from zinc anodes. Since engines use the metal frame as the negative battery connection and the engine is connected to the prop shaft, the engine and the negative side of your 12 volt system are also part of this bonding connection. This bonding wire is usually connected somewhere to the rigging. This is not for electrolysis protection but for some protection from lightning strikes to conduct it into the water through the items connected together.If other currents are allowed to get into this bonding circuit they can easily overpower the small voltage available from your zincs and defeat the protection you need. This is usually the most destructive form of electrolysis and you notice it because your zincs get eaten up very quickly trying to keep up. Under normal circumstances, zincs should last at least a year if they are working normally, and much longer if you don't have any problems. If they are being "sacrificed" in a shorter period you need to find where the external current is getting in.The most common source of this external current is the shore power connection, especially the ground lead. Docks are notorious for bad wiring and often the ground lead is not connected to ground, is connected to the neutral, is being used for carrying current to a mis-wired boat, and all other sorts of problems. So the ground lead should never be directly connected to the ground bonding system we talked about earlier. The purpose of the shore power ground lead is to provide a return path for current if there is a short circuit or power leakage from an appliance or the wiring on the boat. You don't want it to connect all the underwater items on your boat to the underwater items on all the other boats and the dock because now your zinc is trying to protect everyone else too.Unfortunately it is not always possible to keep the circuits separate due to interconnections such as shore power chargers. There are a number of ways to separate the shore power ground from the boat's underwater bonding system. The preferable and safest way is to use a galvanic isolator to introduce a 1.2 volt insulator in the circuit. This is enough to isolate most galvanic voltages but it will still conduct electrical faults and keep the boat safe in the event of a ground fault in the wiring or in an appliance. The galvanic isolator must be rated for the size of your shore power circuit.    From: amelyachtowners@yahoogroups.com [mailto:amelyachtowners@yahoogroups.com]

I know that some of you have replaced the original AMFA 66B fresh water pump.


Do any of you have a repair kit for the AMFA 66B that you want to sell?

Kent,

your prop and transmission are protected by the zincs on the rudder, only as long as they are connected. When measuring the resistance (ohms) between the prop and the rudder zincs, you should not find more than 10 ohms. If you find more, the connection is bad (damaged wire somewhere in the vessel), if you find much more, this means there is no more connection.
If you can't find where the wire is damaged/cut, you should just install a new one, going from the engine cradle to the rudder shaft quadrant. And then check that every item that is supposed to be bonded, is really bonded (check the resistance again).
In the engine room, you should also find a big connection between the cradle and the C-drive (otherwise, as the C-drive is mounted on rubber mounts, it may be isolated from the cradle).
I guess you already know that the ballast must be connected too (thanks to the famous copper strap down in the bilge).

Good luck.

Merci plus, Olivier!  I guess I'll try looking for my problem while I'm STILL waiting for my Cdrive to come back.  Is there any concern to the fact that the damage was to the prop zinc and prop shaft and that the rudder zincs were still intact?
Sorry for the continued barrage of questions, I guess I'm pretty insecure about anything electrical.

Hi Kent,

no need for a wire in the water as, you mentioned it, the bonding circuit is already in contact with water.
However, in case of a power leak coming from the boat itself, you could perform the same tests with the vessel on the hard...
The main question is: is there any connection between the ground circuit (yellow and green wires) and any negative or positive (12V or 24V)?

Have a good day.

Thanks Olivier and Eric!  I knew you guys would clarify this for us.  One question...do we need to have a conductor in the water?  Seems all the things I have read say to connect the battery bank to a wire that goes over the side?  I guess that's the same as  connecting to the bonding system (as long as you know the bonding system is intact)?
Two different methods altogether?
My brain still hurts.

Olivier,Eric,  Thanks for your detailed response. I have been plugged into shore power one day,so that's not my problem. I do not know what my zincs were made from. I bought new ones in St.Martin they probably weigh 3 lbs they are Martyr CMR -5. I will replace them this morning, perhaps I had poor zincs, I hope. I will try to follow Oliviers advise to determine if I have a leak. Eric we were in St. Martins almost 3 weeks ,stopped by your boat a few times, but you were not down yet, or maybe you were just hiding down below, people seem to do that as I come up to their boats. Thanks Again, Pat

Good morning Pat and every happy reader,

the informations in the previous message (from Eric) are very good and cover most of the problem.
I would add the following:
-sacrificial anodes that quickly go are most probably subject to an unusual power leak but first question: were Pat's anodes made out of zinc? In fresh waters, metal boats use magnesium anodes, because fresh water is less conductive and magnesium is more sensitive (than zinc).
In salt water, magnesium will disappear very quickly.
First conclusion: Pat, you should replace your anodes quickly with zinc anodes. how do you know it is zinc? Zinc is approximately 4 times heavier than magnesium. The discs (2) you have on your rudder should weigh around 1.4 kg (3 pounds) each.
-electric leaks often come from the board circuits: a new Equipment (not original) where negative is connected to the device body (Inside, you don't see it): check the conductivity (meter on the ohm position) between negative and body. Your Wind generator could be like that.
This can also be a faulty connection: a loose wire of a navigation light touching the guardrail or mast.
This can even be carbon brush dust creating a connection between a furler motor and the mast.

The method to search for a possible leak is:
-is there any voltage between +24V and ground, -24V and ground, +12V and ground, -12V and ground. Do this test in the engine room as you have there all the power sources available and connect one side of your meter on the engine's steel cradle. If you find a voltage, you should confirm using a small bulb (1 watt). If the light shows, it tells you on which circuit is the leak.
For instance if you find a voltage between the ground (engine's cradle) and the 24V negative, this means there is 24V positive connected to the ground. Then check every 24V item with breaker ON and then OFF.

This search is a very long job, but should start with everything new on board, or every recent job performed.
But remember the leak could come from usual wear.

The last Super Maramus and all AMEL vessels built since, have been equipped with a leak test device. However, this concerns only the +24V and -24V.

The leaks coming through shared earth ground circuits (in marinas) are more and more frequent: don't keep you shore power cable connected when you're away from the boat. Even if you turn off the breaker on the power supply (on dock), your ground cable is still connected: REMOVE THE CABLE from the shore outlet.

One last thing: when one of my clients asks me, I advise to have these checks performed by a skilled electrician...

Good luck.

Whenever different metals are placed in a conductive liquid you create a battery. If you connect these pieces of metal together, current will flow. The current will be removing metal from one of the metal pieces = "electrolysis". If this piece is the zinc in your flashlight battery that is good, but if one of the pieces is your propeller it is bad.
The zincs you use on a boat are called "Sacrificial Anodes". Zinc is used because it has a higher voltage in the water so the current will be more inclined to flow from it than from your propeller. To complete the electrical circuit, the zincs must be connected to the items they are intended to protect. Usually this is no problem because the zinc is bolted right to the shaft or underwater housing. Non metal boats will usually have a copper bonding wire inside that connects all the underwater metal items together so they all share the protection from zinc anodes. Since engines use the metal frame as the negative battery connection and the engine is connected to the prop shaft, the engine and the negative side of your 12 volt system are also part of this bonding connection. This bonding wire is usually connected somewhere to the rigging. This is not for electrolysis protection but for some protection from lightning strikes to conduct it into the water through the items connected together.
If other currents are allowed to get into this bonding circuit they can easily overpower the small voltage available from your zincs and defeat the protection you need. This is usually the most destructive form of electrolysis and you notice it because your zincs get eaten up very quickly trying to keep up. Under normal circumstances, zincs should last at least a year if they are working normally, and much longer if you don't have any problems. If they are being "sacrificed" in a shorter period you need to find where the external current is getting in.
The most common source of this external current is the shore power connection, especially the ground lead. Docks are notorious for bad wiring and often the ground lead is not connected to ground, is connected to the neutral, is being used for carrying current to a mis-wired boat, and all other sorts of problems. So the ground lead should never be directly connected to the ground bonding system we talked about earlier. The purpose of the shore power ground lead is to provide a return path for current if there is a short circuit or power leakage from an appliance or the wiring on the boat. You don't want it to connect all the underwater items on your boat to the underwater items on all the other boats and the dock because now your zinc is trying to protect everyone else too.
Unfortunately it is not always possible to keep the circuits separate due to interconnections such as shore power chargers. There are a number of ways to separate the shore power ground from the boat's underwater bonding system. The preferable and safest way is to use a galvanic isolator to introduce a 1.2 volt insulator in the circuit. This is enough to isolate most galvanic voltages but it will still conduct electrical faults and keep the boat safe in the event of a ground fault in the wiring or in an appliance. The galvanic isolator must be rated for the size of your shore power circuit.

Hi, Pat,
I havent' done it yet, but apparently there's a way you can do this yourself.  With all the different electrical components it can be pretty complicated.  I've been doing some internet research and I'm more confused than ever about exactly how to go about it.  I know someone posted a message with a general description of what you're supposed to do, but now I can't find it.  Your DC systems are likely the cause, either the 24 or 12 V systems...one "expert" says it's the engine/alternators the vast majority of the time.  Some say AC can cause it if there's a bad connection that acts like a diode and converts your AC to DC.  Waaaay out of my comfort level!
 
I read Nigel Calder's book on boat maintenance early on and I know there's a description of the process there.
 
SeaBis makes a unit you can buy or rent that is designed just for this problem.
 
Here are a couple of blurbs about Electrolysis:
 
 
I've been putting this off til I get Kristy back in the water.  When I do, I'm going to hire an good electrician to help me find the problem.
 
I'm sure the experts on the site here will be able to help you more than I can.
 
Let us know what you do and what you find.  I'll do the same.
