Re: [Amel Yacht Owners] wind direction on B&G Hydra

 

John,

OK, wanted to make sure on the high hull number. I think that you may have bought the last 55.

Anyway, the B&G analog 213MHU is repairable with multiple components. I understand that the B&G 608 MHU digital (pictured below) is not. I could tell you all sorts of things about the bulletproof 213MHU, including simple voltage checks to determine the likely part to replace...but unfortunately, I believe that you will have to either see a B&G technician, or buy a replacement 608 digital MHU. 
608 digital

The good news is that the 608MHU digital is about half the price of the 213MHU, the bad news is other than paddlewheel and windvane, it is a throw-away. You could also have a B&G WS310 or WS320 wireless wind unit (pictured below)...these are digitalas well and throw-aways.
WS310 wired

It could be the B&G processor: 
You might have the H3000 processor. If you do and it is faulty, you will probably have to either buy a used one or upgrade to the H5000...but, if upgrade is the case, most of the individual displays and other devices will need to be replaced as well. I think that I would be tempted to buy a new digital masthead unit and try it...most of the digital B&G masthead units only have a life of 5 years, so if you don't need it now, you might need it later...and possibly later, it will no longer be in production...see next paragraph.

The ugly bottom line: 
To meet the demand of new boaters for fancy-dancy, high resolution, touchscreen instruments, and highly integrated electronic navigation systems, manufacturers have been changing systems at the same warp speed of technological advances. Sounds great, right? WELL, the bad news is that these systems, instruments, and devices are not backward capable and usually require similar technology in each device. The result is that when you lose a $500 device in a 2-4 year old system, it might cost $20,000, or more for an entirely new system. 

The sum of the above is the reason that I recommend to owners SMs and 54s with older instruments to repair them as long as they can...those older devices and systems last 20+ years...the newer devices and systems, sadly, will last as long as your smartphone...how long is that? Replacing an entire electronic navigation suite on a cruising yacht is costly, especially if done every 4-5 years. I think most of those people pushing manufacturers along this constant upgrade path, have no idea of the recurring system replacement costs that they will need to budget for. Sadly, almost everyone reading this email either does understand or will.

Ian,

Thanks for the detailed info - that's a great help. The 54 has a Frigoboat with connectors for both high & low pressure. It does seem then that I have a blockage then. I'm in Antigua so finding a vacuum pump at reasonable price may be a bit challenging. If I do find one, then what is the procedure to use it? I assume I connect to the service port in the manifold (the centre one), but then which side do I open - high or low?

Cheers,
Paul

Re: [Amel Yacht Owners] Frigoboat re-charging

Ian Shepherd
 

Hi Paul,

I have been servicing my fridge/freezers on Crusader for some years now, and also the unit in my flat. From what you say, I would suspect a blockage in the evaporator, most likely caused by ice forming due to moisture getting into the system. I would suggest that you add two items to your kit. A vacuum pump and an infra-red temperature measuring gun.

Experience has shown me that it is generally a waste of time and gas re-gassing without evacuating the system for a minimum of 30 minutes on a low pressure system such as the SM Frigaboat equipment. High pressure systems need maybe 15-25 minutes longer if you have added one to you boat, such as a ice making machine. Vacuum pumps are available at a reasonable cost and well worth having.

I had a symptom similar to yours on my Scholte fridge freezer in my flat recently. After about 20 minutes of evacuating there was a sudden plop and the obstruction came free. Again I suspect it was caused by ice.

When it comes to re-gassing, I have read of many ways, some even measuring the current taken by the compressor. However, this is what I do:

1/ Vacuum pump for 30 minutes. Close the manifold valves and switch off the pump. Monitor the vacuum pressure for about 20 minutes. If it starts to decrease , you have a leak. Then I think you do need an expert to come find it and fix it.

2/ Let your R134a into the system for about 5 seconds only, then switch on the fridge with the thermostat turned fully up. The compressor has an outlet pipe called the liquid line, and a return pipe called the suction line. The connector that you attach your blue hose to is usually close to the compressor on the suction line.

3/ Touch the liquid line with your fingers. It should get hot. If it does not, then add more gas a little at a time till it does.

4/ Once this is happening you have compressed refrigerant on its way to the condenser which removes some heat through the fan, before it travels to the evaporator chest, which doubles as the ice box on the Frigaboat fridge.

5/ Using an infra-red temperature gun, measure the temperature of the evaporator chest. It should be headed downwards so somewhere around -15C on the fridge and -25C in the under the salon seat freezer. Remember it does take time to achieve these temperatures. The temperature around the whole of the evaporator chest should be about the same. If it is not, then you need to add more gas a little at a time and wait before re-measuring. Patience is the key word.

6/ Finally feel the temperature of the suction line close to where it enters the compressor. It should feel no more than cool, with perhaps a wet feel to the pipe. If it ices up, it means too much gas and that liquid is returning to the compressor instead of heat carrying gas.

It does take a lot of patience to get the balance just right. I leave the bottle and manifold connected for a full day before I am satisfied that I have it about right. Usually I end up with a suction line pressure of around 5-6 psi, which corresponds with what I have read, 7 psi being the maximum that an R134a system should run, or so some say.

I hope that this helps Paul. It's a bit of an art to get it right and I have had some professionals make a complete mess of my refrigeration, and others that have done an excellent job. However, when you are 'out there' and it goes wrong, there is no money better spent in having the equipment on board to fix it whist under way.

A quick question. How did you measure the high pressure side of the compressor? Did you fit a line tap? Maybe there is a connector on the liquid line as standard on the 54?

Hi all once again!

I'd like to resume this thread having now acquired a gauge set and a cylinder of R134A. After lots of trawling the web, tI'm still not 100% sure about my diagnosis for my faulty freezer. After running for quite some time, the high pressure reading is 105 psi and the low is minus 10 in Hg. This leads me to believe that there is a blockage in the capilliary tube or the evaporator, as from what I have managed to find out the low pressure should be around 7-10psi. The high pressure tube frosts up to the point of entry to the evaporator but the evaporator remains cold but not frosted. I've tried heating it with a mini blow torch (as I've seen fridge techs do) but to no avail.

I would be interested if someone could confirm my diagnosis or correct it if it is wrong, and offer any further advice on how the remedy the problem. I understand it may require a vacuum in which case I'll have to get the experts in.

Re: [Amel Yacht Owners] Bow-Truster overheat

Hi Mohammad and Aty,

So you don't have that 425A fuse on Kokomo?
It'd be interesting to have other data points. 

When we started seeing A54s for sale, someone from the yard in Hyères told us Amel started to fit the emergency disconnect on 54s  after instances of incidents where the bow thruster wouldn't stop. The thermal switch should provide that safety stop, but maybe they felt there should be a manual override too, in case.

By the way, it was in the same sentence as "have the genset running when you use the bow thruster" that raised a few eyebrows in this group a while back. At the time, not knowing better, I took it for granted. Sufficient and safe, yes. Necessary?, I'm not sure. We don't do it anymore as we don't go to marinas that much and when we do, we try to play the game of least-bow-thruster-usage to improve our handling skills, and our batteries can handle the high current discharge.

Hi Mohammad,

On Garulfo (54-122) there is also a 425A fuse on the positive cable and an emergency disconnect (big red button), both housed in the box inside the forward locker. 

I recently found the emergency disconnect to be rusted frozen so it's on the list for replacement. 

I would encourage others to test the emergency disconnect as it has a carbon steel backing plate and is mounted without any kind of waterproofing so is bound to rust.

I'm not aware of any adjustments in the thermal cutoff. The bow thruster has a direct connection to the batteries without a breaker. The thermal cutoff is the only safety items preventing major damage to the thruster and/or wiring.
 
Try to use the thruster in bursts (less than 15 seconds), as much as possible, so it has time to cool down between usage. We try to over correct a bit when we use use the BT so as the bow falls off, the BT has more time to cool.

Subject: [Amel Yacht Owners] Bow-Truster overheat


 

Dear Forum

On my Amel-54 I discovered that the bow truster stops working after repeatingly use within 10-15 min timeframe.

I used the bow truster a bit more than usual when I practiced some manouvers first time; - and on a second occation when I had to manouver in a marina with a lot of windguests of 18+ kn and another chain over my Anker.

It stopped working and after a while (maybe 10 min.) it re-started & operated normaly. I know BT Is not made for constant use, - only few seconds at a time. Then wait and re-use another time.

Question from a beginner:

Does the bow truster has a termic fuse which is activated after some time of usage to save the motor from overheating? 

Does anyone know exactly how it works and if this can be adjusted because I think the BT on Wasabi switches of quite fast. Any ideas or other information?

Best regards

Hi fellow Amel owners,

From and environmental point of view; I feel that there is no problem at sea and in the open ocean. There is certainly a lot of hypocrisy regarding commercial vessels being permitted to use tin based antifouling. I do not claim to be very knowledgable on the chemistry and biology involved.

However in marinas,  rivers and harbours there is often a high concentration of yachts that just sit there year in year out, thousands of them.  Antifouling with tin based paints is probably very harmful to aquatic life. I should also mention that these areas are traditionally fish nurseries and under a lot of pressure from agricultural run off and general pollution. Not to mention the sanding and painting that boat yards do. I know in many places they are supposed to capture the residue, but in the real world how often does that happen?

So yes in one way it is a shame that we can not apply a bottom paint that will last 5 years but we have a duty to look after our seas and inland waterways after all we are yachting for pleasure.

When I bought Amelia in June 2017 the existing bottom paint was Micron 66. I decided to leave it and see how it fared as I was due to haul in Trinidad for September to December. It was still perfect so I left it again, but added a coat  of Micron 77 to the rudder. It is still perfect. I wonder how eco it really is.

Re: [Amel Yacht Owners] Isolated grounding question - solar installation

Thank you all for your thoughtful responses.  I find this forum to be one of the great aspects of owning an Amel.  In the short time I have owned my own Amel, I have gained such a tremendous amount of knowledge and understanding just from the ongoing discourse on this forum.  

As far as the solar panel arch and panels:  yes, my panels do have an aluminum frame.  I might use G-10 insulation at the mounting points of the aluminum solar panel frames to the steel arch, but it seems as though there is no strong argument to connect the arch to the bonding system.  
I will tackle this project in another two weeks and hopefully post some photos of the installation… always interested in the critique from those more experienced than myself while I’m on this incredibly steep learning curve!

James,

I believe that if you assembled an expert panel to discuss this issue consisting of Nigel Calder, Henri Amel, Joe Dwyer (lightning expert), the best marine surveyors, and others, the shining star on that panel would be Henri Amel. Sure, that belief is personal and could be argued. Maybe what cannot be argued on this issue is that more design, effort, and money is has been but into each Amel Yacht during the last 20 years than any other builder of production pleasure yachts. I personally have had issues with a few Nigel Calder doctrines, but I can understand when he write these as "one-fits-all-boats" he certainly can be a little 'Off" on one design/boat.

From personal experience:
I do not believe that bonding is required on the arch of a SM anymore than its life rail, standing rigging and masts...they are not bonded by Amel, so Henri Amel agrees. My guess is, that as unpredictable as lightning is, it 
almost always strikes the masts. 
​BTW, ​
I am thankful for the carbon fiber masts...they make excellent lightning rods. I have twice experienced lightning strikes in anchorages where "unpredictable lightning" struck boat
​s​
with a carbon fiber mast
​s​
, and left all the rest of us mostly untouched.


Little side note: After Henri died, the management of Amel decided to add some things 
to the Amel bonding system
​ ​
like standing rigging and life rail
​. I wonder whose research they used, or maybe they thought it is easier to bond, than to explain? I will never know the answer to that question.​
 

EARTH to the Arch & Frames:
I do not think that DC Negative is attached to the solar panel frame. How do you know that it is? Home solar installations normally require a "safety ground" a/k/a EARTH attached to the frames, then to EARTH. It is possible that some expert, somewhere, has googled this point and relayed it to you. Remember DC Negative is not EARTH, and your Amel does not have an EARTH circuit for DC Voltage. I believe that the arch is isolated from DC Positive and Negative, and if so, connecting the Arch to Amel bonding is OK, but probably not necessary. Probably more important is dissimilar metal corrosion when using stainless steel and aluminum in the same construction. I know this is probably not the case with your Emek Arch, which is stainless, but, do your panels have aluminum frames?

 My view re potential electrolysis is that on balance every metal fitting should be linked to the bonding system, but the important ones are the sea water exposed ones like through hull fittings and sea water pumps. The idea being that there is no potential difference between any one piece of hardware and another.

This leads me to believe that there is a blockage in the capilliary tube or the evaporator, as from what I have managed to find out the low pressure should be around 7-10psi. The high pressure tube frosts up to the point of entry to the evaporator but the evaporator remains cold but not frosted. I've tried heating it with a mini blow torch (as I've seen fridge techs do) but to no avail.

I would be interested if someone could confirm my diagnosis or correct it if it is wrong, and offer any further advice on how the remedy the problem. I understand it may require a vacuum in which case I'll have to get the experts in.

Hi Mohammad,

On Garulfo (54-122) there is also a 425A fuse on the positive cable and an emergency disconnect (big red button), both housed in the box inside the forward locker. 

I recently found the emergency disconnect to be rusted frozen so it's on the list for replacement. 

I would encourage others to test the emergency disconnect as it has a carbon steel backing plate and is mounted without any kind of waterproofing so is bound to rust. 

Fair winds,

Hello Reudi;
 
Yes, the Amel 54 has a thermal cutoff to prevent damage to the thruster as well as continuous high current draw (Around 550 Amps at 24V) which could lead to fire on board. We've had the thermal cutoff kick in  only a couple of times and it has reset in a matter of minutes. We have not timed the exact reset duration.
 
I'm not aware of any adjustments in the thermal cutoff. The bow thruster has a direct connection to the batteries without a breaker. The thermal cutoff is the only safety items preventing major damage to the thruster and/or wiring.
 
Try to use the thruster in bursts (less than 15 seconds), as much as possible, so it has time to cool down between usage. We try to over correct a bit when we use use the BT so as the bow falls off, the BT has more time to cool.

Subject: [Amel Yacht Owners] Bow-Truster overheat


 

Dear Forum

On my Amel-54 I discovered that the bow truster stops working after repeatingly use within 10-15 min timeframe.

I used the bow truster a bit more than usual when I practiced some manouvers first time; - and on a second occation when I had to manouver in a marina with a lot of windguests of 18+ kn and another chain over my Anker.

It stopped working and after a while (maybe 10 min.) it re-started & operated normaly. I know BT Is not made for constant use, - only few seconds at a time. Then wait and re-use another time.

Question from a beginner:

Does the bow truster has a termic fuse which is activated after some time of usage to save the motor from overheating? 

Does anyone know exactly how it works and if this can be adjusted because I think the BT on Wasabi switches of quite fast. Any ideas or other information?

Best regards
