Re: Windlass/Genoa Furler electrical problem, circuit breaker bad?

DEARS, 
it could be that the  two windlass  switches on the top of the anchor windlass maight  allow some water infiltration that  causes the problems of the short circuit with the relative high ampere flux. 
We had to substitute the switches  .

Hey Amelians! So I'm stuck here in total lockdown in Greece (really can't complain, it's amazing), so it's not a tragedy, but the circuit breaker on the windlass/genoa circuit of our SM is tripped at some point this winter (in the last few weeks sometime) and won't stay in the up/on position. Being in lockdown, getting parts is almost impossible, but I do have a spare 100A circuit breaker that would fit. Since the space to install is very limited (I can't even put a multimeter probe on the top of the breaker without pulling things out), I was hoping I could get confirmation from y'all that the circuit breaker is the most likely culprit....

SYMPTOMS: When I use the dashboard switches for windlass or genoa (or the foot switch for the windlass also), the solenoids in the cabinet click happily and strongly. But the breaker stays down, and nothing will keep it up. When I cut the 24v power at the battery banks, the circuit breaker still will not remain on. If I hold the breaker open/up and have someone activate the switches in the cockpit, still nothing but clicking from the solenoids. 

Anyone see a problem with swapping out that breaker as the fix? How often do they fail? I don't remember a broken breaker being a very common thing in my life, so just wondering before I wedge myself up there and start hammering :D 

Many thanks!

Hi Davi,

If it is a swap to a new breaker of the same capacity that is a reasonable test with low risk. Just do not hold it up if it pops.

Hey Danny, just to clarify, the breaker there now is 100A, so this is a straightforward swap. I'm trying to get my head around the odds it is the breaker. Both windlass and genoa worked fine a week before this. Wouldn't the breaker stay up if the battery power was cut off to the circuit if it was still good, even if there were a short? There should be no power going to the devices, hence no short to flip the breaker...?

Hi Davi,

I would advise care. A breaker pops usually because there is a short circuit down stream from it. It is there to stop wiring burning or electrical gear being damaged. So adding a high amp replacement is high risk.

Hi Amo,

Thank you for your thoughts. I appreciate them.

I have been coming to St Maarten for over 22 years and know many people in office and

In official positions.

Hank from Avocation is a friend of mine and it just hurt me to hear his tale.

Hi Eric,

I'm a resident of St. Maarten.
I will not try to defend the gouvenment of St. Maarten as these are as incompentent as they get in the Caribbean. However the current situation in the world makes even the most "civilised" country a madhouse for regulations. Please show me a country that hasn't come up with measures that seem downright silly at this point in time. None of the country's (if you want to call them that) in the Caribbean is prepared for these kind of problems, so please cut them some slack. It's not easy for the officials to apply the rules if the government changes them almost every hour.
The fact that St. Maarten uses double standards is a fact know to everyone in the Caribbean and there are very few Island that act differently. It how the Caribbean operates, no thanks to the former colonists.

So I feel sorry for you that your plans are blocked for now but you are not the only one and everybody is trying to circumvent the rules in ways they see fit. So I would not like to be a "official" at this point in time no matter how crazy they can be during normal times.
The support St. Maarten gets from the Dutch government (being part of the same Kingdom) is quite sad as well.

So if this a a proof of anything it's the proof we still have a long way to go as humanity to properly rule the world.

Just my two cents.

Good afternoon Alexandre,

Thank You for keeping an eye on Kimberlite !!

 

I completely understand the logic about not letting anyone on to the island. However Hank offered to self quarantine outside the bridge for 14 days.

 

Secondly did you notice this in his email? I cannot understand why this anomaly happened – I guess money talks.

 

What I left out in my article is that I watched the Mega Yacht “Seven Sins” make the bridge the day after I arrived and was at anchor refused entry.  So they can break the rules for some boats, but not others. Please pass this on to your friend. They can make exceptions for those who have money, but not for friends like me. The boat had several guests and more crew aboard and came from St. Bart’s, one of the infected islands.  I made sure I did not stop in a French island, but that did not matter after all, did it?. I tell the people from SXM who have responded with the same reply, “Don’t make excuses for your badly trained and surly customs agents.”  The locals never have to deal with them and we know better. So don’t buy that cr*p about they are just following the rules. Bull*hit!

 

My town on Long Island, Huntington, is the epicenter of the virus on Long Island with more than 1000 cases.

New York state had almost 2000 deaths yesterday. We are all aware of the hazards of the virus. The projection for the USA and the peak of the deaths in the USA will occur about April 14 with about 2500 deaths that day. It just annoyed me that they let the big yacht in and did not allow Hank to stay at anchor for 14 days.

 

Please stay safe and say hello to my friends on the island.

 

I am looking forward to seeing you soon.

Fair Winds

Eric

Good morning Eric, 


Advocation has been the gossip of the island. 

But I think, he needs to understand that since the 22nd, the island is in complete shut down, no one, not even the “resident” are allowed to come in.  

This was announced 5 days before he arrived…. 


It is for safety measures.  Sint Maarten has very little medical resources and can not take any chances… 

Already our case jump from 6 to 16 plus as many on the French side.  

That is 3 time the world average...  

People on critical condition on the French side are flown to Guadeloupe where they usually arrive too late.  

One just died yesterday on the Dutch Side.  


About boats passing the bridge: 

vessels already here have the right to pass the bridge, just like people can use their dinghy or people can walk in the street.  


Being in Sint Maarten, I am very impressed on how the government is taking initiatives, sure they are strict,  but I think proportional to the risk and its consequences.  Keep in mind Hurricane Irma is a very vivid memory in all of us.  


On a personal note; I haven’t been able/allowed to go back to Kimberlite, but I checked with binocular.  

When the curfew is lift, I will be glad to assist.  


Sincerely, Alexandre

Re: prop zincs ,WOB Corrosion, more than you ever wanted to know about...and a message to Kent from Olivier

Thank you Joel.  As usual, your perspective is extremely valuable to us all.  I appreciate the Amel design and rarely deviate from it.  Since mine is a MaxProp, I can still put a zinc in it and still claim it is the Amel way.
It occurs to me that if I hadn't been using the prop zinc, things might have been worse, since that was the only thing protecting the CDrive.  I have been very good about checking the bonding system once a year since I had the electrolytic damage to the prop shaft, and checking hull potential every month and anytime I time up to a dock.  That's apparently not often enough, hence my moving it to the quarterly maintenance list

When I check hull potential, I do turn everything off and back on one at a time.  So far no surprises!

Thanks again, and Iris says Hi!

Hello everyone and here is yet another installment of more than you ever wanted to know about…

During my first visit to Chantiers Amel in the early 1980’s  I spent several hours each day under the tutelage of Jacques Carteau, the Technical Manager at Amel. His job was to take Captain Amel’s thoughts and ideas and turn them into the diagrams, lofts and procedural instructions to make these ideas into a boat. At that time, Mr. Carteau knew more about everything Amel than anyone else at the shipyard. Mr. Carteau could tell I was enthusiastic to learn about all the technical and construction details and, over the years, gave me an incredible education about just about everything that happened, start to finish, when building an Amel boat. Amel insiated that anyone who made representations about their boats to really know what they were talking about and they spent lots of time over the years making sure I was fully familiar with the entire boat and all systems aboard.

 

There were in depth instructions about all the systems. He explained that Amel boats, every one/every model, had a full earth return/full floating DC electrical system. Simply, this means every bit of electrical energy comes out of the batteries , supplies power to the device to which it is connected and then returns left over energy back to the batteries. If this system is not corrupted, it just about precludes electrolytic corrosion.

When I asked why none of the Sharki, Maramu or Mango boats had zincs on the prop shafts or propellers, even the ones on the way to be launched, he took me to his office and showed me the diagrams for the galvanic anode/zinc system we all have on our Amel boats. This joins every piece of metal near or below the waterline and carries any stray current back to the two zincs on the rudder. He explained in great detail ( I should have taken notes as details dim after nearly 40 years ) how this system was perfectly galvanically balanced and no additional zincs were needed anywhere. He also explained that to introduce more zincs can have a negative effect on the whole system and actually cause metal wasting when the system goes out of balance. It was all kinda like alchemy to me but, hey, this was Mr. Carteau, Amel’s right hand man.

 

Why all this explanation? Because it is imperative to the good health of our boats that these carefully conceived systems be kept as designed and well maintained. Keeping connections clean and securely fastened is imperative. Don’t let someone totally unfamiliar with the totality of these systems ever give you guidance about changing them to something they are more familiar with. Over the years I can’t tell you how many times that shipyard/repair managers have called me  to tell me how stupid the Amel drive system is, how the bow thruster was conceived by a moron and built by a monkey, or that all those wires carrying DC electricity back to batteries was just plain old stupid and entirely unneeded…I could bore you with more but you get the picture.

 

I call it “The not invented here syndrome”. If some well experienced marine tech sees something unfamiliar, well, it can’t be any good and probably doesn’t work well for very long and blah blah blah.  Don’t let people like this on your boat.

 

Oh, in closing, no Amel built boat with an Autoprop ever left the factory with a zinc on the prop. Not one. Only got the red plastic cap. Honestly, you really don’t need a zinc. Some folks follow the if enough is plenty, more is better rule and put a zinc on. Probably won’t hurt anything but it does not help anything either. Just to be safe incase my recollections are suffering from geezage, I checked in with Olivier. He said the ONLY boats that had zincs on the props were boats with a Maxprop and only because they didn’t make a plastic cap as a replacement and the stuff inside the prop lasts longer if foreign bodies are kept out.

 

Kent, Olivier suggested the next time you do your testing, do it while turning on just one electrical device at a time and see if there is any major difference and if so, investigate that fully. Kent, your boats first owners were nice folks but not mechanically sympathetic. You are to be highly commended for your rescue of and continued efforts to improve KRISTY.

 

Have fun with your Amel boats everybody!

Thanks, Mark.  Interesting to know.  I have a MaxProp Classic.  They sell stainless steel hex bolts for the zinc.

Anyone have suggestions for something I can put between the zinc and aft side of the prop to improve contact?

 

I was able to remove the bad WOB by drilling two holes and using screws to pull it out.  It came out with just a little coaxing.

 

See pic.  The galvanic damage extended about half way through the WOB.

 

I tested continuity between the prop shaft and bonding system and found NO LOAD!!!

Further investigation showed bad connections between the CDrive and engine bed.  After cleaning those up, still NO LOAD. Cable was bad, too, inside the connectors.

I've now confirmed no resistance between the prop shaft and the rudder zincs.

 

If this had been worse, I could have had catastrophic failure of the WOB, and who knows what kind of other damage...I got lucky this time.

 

Soooo, bottom line for me is that while hull potential is a good measure of overall bonding efficacy, we must REGULARLY measure continuity at ALL metals exposed to sea water to confirm that they are protected.  It goes on my quarterly maintenance list today.

Hi Kent, 

 

I do like the Dremel idea; it will allow you to section the WOB and remove it like a dentist removes a wisdom tooth. 

 

I wanted to let you know that every time I have ordered prop shaft zincs they have come with the plastic screws.  The zinc has exhibited “normal” wear but has never fallen off.  The Autoprop website has a video showing the rebuild of an H5 and references removing the plastic screws when disassembling the prop.  I believe metal screws provide a preferential contact area on the mounting tabs enhancing the destruction of the tabs whereas the plastic screws spread out the contact area to the body of the zinc – just a SWAG.

 

Good luck with your project.

Re: WOB Corrosion

Danny and Yvonne SIMMS
 

Hi again Gary and Kent, further to my last. I do depart from Amel advice regarding zincs. Because the c drive, the shaft and the propeller are so critical I always have a shaft zinc between the prop and the c drive. Yes the Amel bonding system makes this unnecessary, but only if all the connections are always perfect and in my long experience it is very difficult on a boat to be certain that all connections are always perfect. This is my backup defence. I know it can be argued that this means I am "over zincing" but I prefer that risk to the other. I have the plastic cone on the prop.

Kind regards

Danny

Hi Kent:  What a great find and a great discussion along with Joel's post.  Sooooo valuable.  Thanks for sharing.  Glad you got that WOB (wearing out bearing) out.  It is still a bit of a mystery to me as to why only that corroded.  The color (salmon like) looks like de-zincification.  I am only speculating but, since brass is copper and zinc, the zinc in the brass was the least noble element in that vicinity (i.e.the prop, c-drive shaft etc.) Everything must have all been more noble metals, so with no continuity of the C-drive to the normal sacrificial anodes (on the rudder), the WOB became the sacrificial anode for your C-drive.  I guess it only corroded where it was in contact with sea water and hence the lack of corrosion "inside" the lip seals etc. 

Again, thanks for you invaluable reminder about preventative diagnostics on our bonding system.
