Re: [Amel Yacht Owners] Re: Distributed vs. Conventional Electrical Systems

Bill & Judy Rouse <yahoogroups@...>

Bill Kinney,

I assume that you must be asking your question to Amel, because Amel is the one that published the Super Maramu 2000 Owners Manual (page attached).

Amps = Watts/Volts.
Watts = Amps x Volts

So, either Amel is wrong with Watts or Amps, or both.

What calculation did you do to convert 7000 Watts to 510 Amps?

For what it is worth, the name plate on the motor on my older Super Maramu (they might not all be the same) is 6.3kW

To get a good number, for current draw you can't assume 24 Volts.  When you are drawing that much power, the voltage will drop, a lot.

For really high power draws like this, it is not unreasonable to assume as low as 18 Volts.

6,300 Watts/18 Volts = 350 Amps

If we do go with a 7000 watt rating, that's still "only" 388 amps.  A perfectly reasonable number to protect with a 500 Amp fuse.

Re: [Amel Yacht Owners] Re: Distributed vs. Conventional Electrical Systems

greatketch@...

Ryan,

I considered the scenario you describe, and decided it is not a worry for a couple of reasons. I agree it is a theoretical concern, but not a practical one.

First, if I am drawing significantly different amperages from my 4 parallel pairs of batteries then I have very serious other problems that will kill the batteries quickly because of mismatched charge/discharge profiles that have nothing to do with the fuses.

If I am drawing power close to the maximum carrying capacity of the fuse, of course one will blow first.  But then the power draw from the other three immediately jumps by 33%.  For fuses already on the edge, that will surely cause a very fast failure.  It is POSSIBLE, but very unlikely, that the power would be shut off before the failure cascades to the other batteries. In the case of the kind of short circuit I am actually trying to protect against, of course there is not a shut off option.

Finally, as fuses age, they can sometimes fail below their rated capacity.  This is, I believe, the most likely way I could lose one fuse and not the others.

If one fuse was to fail, and I lost 25% of my battery capacity, I would very quickly notice that by the way I monitor my battery charge/discharge cycles.  That is exactly the kind of problem I am always on the look out for because it could indicated a shorted cell in one of the batteries.  A potentially dangerous situation I would very much like to know about if it happens.

The other problem I have found, is getting a fuse rated to interrupt 500 DC AMPS in one package gets rather difficult, and expensive.

Actually, this was not the exact key blank. Bob at ACE took a blank that was similar but a little short. He then cut into the metal at the opposite end to create the full length. And presto, new key. Works beautifully. That's why I called Bob a master key maker.

Re: [Amel Yacht Owners] Bow locker bottoms...

greatketch@...

James,

The Super Maramu deck locker gaskets are really cleverly done as made at the factory.  They used a hollow "D" gasket with solid rubber inserts at the corners of the hatch to keep from over compressing the gasket and shortening its life.

Like so many things on an Amel, it is a simple, elegant solution I hadn't seen before.

Bill,

Sueno only has 50 meters of 3/8” chain plus 40 meters of 7/8” Nylon spliced to the chain.  The 50 meters does not make a very large pile.  I have two of the approx. 30”  x 3/4” thick  closed cell foam play matts that I set on the deck just aft of the sub. bow locker on to which I pile the chain.  I don’t lay the chain out for rinsing because of the possible deck damage you are referring to and I don’t think that it is needed to get the salt off.  There are lots of holes in the piled up chain to spray water into and just a couple minutes  of rinsing seems to be all that is needed.  The chain seems to dry out quickly in the sun in the Med., the line is a lot slower taking a day.  I don’t bother to do this while I am cruising continuously but when I stop at a marina with water available this is one of the first tasks I attend to on the boat after getting things secured.  The chain locker also gets a quick rinse and a sponging of the bottom.  My drain is slightly above the bottom of the locker for some reason,  I was thinking of changing this so that all of the water would drain out of the locker without any bailing.  Is there an Amel reason for not having the drain at the very bottom of the locker?   This is the first boat that I have owned on which the “Things to change” list has gotten shorter the longer I have owned the boat and I am being careful not to alter anything unless I am really sure it should be done.

Thank you for telling me about the Super Maramus not having drains for the deck lockers,  I am surprised that I missed that point and am glad to be corrected.  In case it helps, I think that the drain arrangement on the Maramu was very intelligently done by Amel.  There are two drains of course, Port and Stb. with cowls over the holes facing aft.  But the really interesting part of the design is that a trough was created between the drains Port and Stb. so that any water that comes in one drain tends to stay in the trough and  run right across and out the other side.  I have never seen anything in the locker before other than some minor dampness in the areas of the drains so I think that the locker bottoms might also slope to the drains.  I have also not beat to windward in more than 6’ seas nor seen more than 43 knots on this boat so maybe in severe conditions the drains are more of a problem. I am considering a minor change in the drains.  It should be possible to create a baffle that would prevent the entry of any water into the lockers from the drains.  It would work a little like the Aqua lift muffler to block water flowing in and allow any water that did enter to flow out of the drain when the bow lifted.  The twist turns on my bow lockers don’t really apply any compression to the gasket.  Are the bow locker gaskets compressed on the Super Maramu?

Keeping spaces, stuff salt free and dry on a cruising boat is a real challenge,  I completely agree with you.

James

Dear Bill,

It is with sadness but understanding that I see you retract yourself of the Forum…
This was my fear after I heard you sold BeBe and was glad you kept active.
I am glad the Amel School is working well and hope it continue to grow.
I can’t thank you enough for all the years of wonderful support.

All
Amel Owners and Friends,

I
have participated in this forum and with this wonderful
group of people for 12
years. It has been fulfilling, educational, and occasionally
entertaining.

As
many of you know, we sold BeBe to great new owners, Dan
& Lori Carlson,
earlier this year. Many of you asked me to continue as part
of this group and I
have tried to participate when I feel as though I have
something to contribute.
You may have noticed a recent lack of
participation.

And,
as some of you know, several months ago I started Amel
School
which gives me the opportunity to train
owners that are new-to-Amel. I also help those who want to
the best Amel for their budget (Pre-Purchase
Consulting).
I had my 400 page Amel
Book
printed and bound
for my Amel School clients and I provide 24/7
Support to
them. I am
proud to say that in a few months I have clients throughout
the world and just
added my 20th client. Most are members of this
Group.

This
brings me to what I need to post today. I am going to almost
totally
remove myself from the Amel Yacht Owners Forum. I need to do
this to be able to
serve my clients properly. I do hope that you understand
this. In the past few
months I have been asked by a number of you about my Amel
Book and other Amel
School related services. I have a parting offer for members
of this Yahoo Amel
Yacht Owners Group who have owned their Amels for 2 years or
longer. If you are

Hopefully
we will meet (again) somewhere on the water while I am with
one of my Amel
School Clients. Best,

Craig,

I agree with Alan's point and before we sold BeBe I had decided to place 6 of the Blue Sea 5191 MRBF Terminal Fuse Blocks with a removeable Blue Sea BS5185 (150A) amp fuse on each of the 6 positive battery pairs on the positive post  of the battery and connect the the positive lead for each pair to the newly installed terminal block fuse. My assumption was that the 500 amp bow thrust er would not burn individual 150 amp fuses...I may be wrong on this. The fuses are available from 50 amps to 300 amps. Since the fuses are replaceable, I was going to buy extras.

Of course, I have not tested this, so I cannot say that it works and/or whether it is the best solution.

This brings me to what I need to post today. I am going to almost totally remove myself from the Amel Yacht Owners Forum. I need to do this to be able to serve my clients properly. I do hope that you understand this. In the past few months I have been asked by a number of you about my Amel Book and other Amel School related services. I have a parting offer for members of this Yahoo Amel Yacht Owners Group who have owned their Amels for 2 years or longer. If you are interested please follow this link to a hidden page on my website: Amel Yacht Owners Group.

Hopefully we will meet (again) somewhere on the water while I am with one of my Amel School Clients.

Best,

Re: [Amel Yacht Owners] Re: Distributed vs. Conventional Electrical Systems

I believe you're supposed to fuse the battery bank as a whole, and not individual batteries.  That means one fuse for the whole bank.  The reason for this is that some subset of the fuses could blow (one could be slightly more sensitive, or one battery might supply slightly more current under load) and you wouldn't know.  You would hope that a cascading failure causes them all to blow, but it won't necessarily.  And this is bad because now you have one or more batteries isolated from the rest of the bank, yet you still have power, so you're probably not going to go look under the bunk to check the fuses.  With your battery bank now smaller than you think it is, you're likely to discharge it deeper than you intend, and the isolated battery won't be getting charged... quickly all the batteries will be ruined.

I'm a big fan of those battery terminal fuses Bill mentioned.  I installed them on my old boat after reading this excellent article (that whole site is fantastic).  I'm going to do something similar on my SM as soon as I figure out what the current rating should be; it might be possible to get away with a 300A fuse since they don't blow instantly.  As long as we're not leaning on the thruster or windlass switch for too long, I think it would be OK, but I'd love more info about the actual current draw of these systems.

Bill,

Is it correct that the bow thruster on the Super Maramu is 500 Amps?  And that is at 24 volts?  The thruster on my Maramu has a 100 amp breaker installed by Amel ( it has never tripped so I assume the normal draw is something below 100 amps)  and the voltage is only 12 volts so if my math is right it is about 1.5 hp which is good up to about 15 knots or so.   500 Amps at 24 volts would be about 16 hp?  Can you tell me the size of the original Amel breaker that is installed on the Super Maramu?

Thanks for all of your past help with my Amel.  And to update you on the bow thruster leakage.  After replacing the seals as instructed, the thruster did not leak at all this season.    The thruster has also been 100% reliable thus far and is a tremendous asset IMO.

I will consider adding some inline fuses to my boat as well just in case of a major short.

I agree with Alan's point and before we sold BeBe I had decided to place 6 of the Blue Sea 5191 MRBF Terminal Fuse Blocks with a removeable Blue Sea BS5185 (150A) amp fuse on each of the 6 positive battery pairs on the positive post  of the battery and connect the the positive lead for each pair to the newly installed terminal block fuse. My assumption was that the 500 amp bow thruster would not burn individual 150 amp fuses...I may be wrong on this. The fuses are available from 50 amps to 300 amps. Since the fuses are replaceable, I was going to buy extras.

Of course, I have not tested this, so I cannot say that it works and/or whether it is the best solution.

Re: Companionway key

greatketch@...

I think that lockset is the ONLY part an Amel shares with a Beneteau...

Anybody can CUT the key, the problem as most people have found is the key blank itself is rather rare--at least in the US.

After struggling to find one in Florida, Karen carried one while visiting her sister in Texas, walked into an old-fashioned locksmith shop. The guy took one look and said, "A Y2!  You don't see those too often."  He reached up to his board and pulled one down.  Presto!  We had the spare key we had been looking for.

I don't know what the difference between a "Yale Y2" and a "Y1-E ACE" is, if any...

We ordered a stash of 10 of the same blank from Amazon. They work in our lock.  If anybody else gets stuck, let us know and we'll drop one in the mail to you.

SM Furling Motor Brush Dimensions

Ian Shepherd

Hi,

can anyone please tell me the LENGTH of the carbon brushes for the Leroy furling motor when they are new? I am trying to source spare brushes locally or on eBay but do not have a new brush left to measure. Obviously I can measure the side dimensions from my worn ones. If possible can you please state the length in millimeters.

Incidentally, when the motor starts to play up I found that swapping the top and bottom brushes over the best way of restoring normal operations. Cleaning the brush surfaces and the commutator only worked for one or two cycles whereas swapping the brushes seemed to fix the problem more permanently.

With thanks

Re: [Amel Yacht Owners] Bow locker bottoms...

James Alton

Bill,

Sueno only has 50 meters of 3/8” chain plus 40 meters of 7/8” Nylon spliced to the chain.  The 50 meters does not make a very large pile.  I have two of the approx. 30”  x 3/4” thick  closed cell foam play matts that I set on the deck just aft of the sub. bow locker on to which I pile the chain.  I don’t lay the chain out for rinsing because of the possible deck damage you are referring to and I don’t think that it is needed to get the salt off.  There are lots of holes in the piled up chain to spray water into and just a couple minutes  of rinsing seems to be all that is needed.  The chain seems to dry out quickly in the sun in the Med., the line is a lot slower taking a day.  I don’t bother to do this while I am cruising continuously but when I stop at a marina with water available this is one of the first tasks I attend to on the boat after getting things secured.  The chain locker also gets a quick rinse and a sponging of the bottom.  My drain is slightly above the bottom of the locker for some reason,  I was thinking of changing this so that all of the water would drain out of the locker without any bailing.  Is there an Amel reason for not having the drain at the very bottom of the locker?   This is the first boat that I have owned on which the “Things to change” list has gotten shorter the longer I have owned the boat and I am being careful not to alter anything unless I am really sure it should be done.

Thank you for telling me about the Super Maramus not having drains for the deck lockers,  I am surprised that I missed that point and am glad to be corrected.  In case it helps, I think that the drain arrangement on the Maramu was very intelligently done by Amel.  There are two drains of course, Port and Stb. with cowls over the holes facing aft.  But the really interesting part of the design is that a trough was created between the drains Port and Stb. so that any water that comes in one drain tends to stay in the trough and  run right across and out the other side.  I have never seen anything in the locker before other than some minor dampness in the areas of the drains so I think that the locker bottoms might also slope to the drains.  I have also not beat to windward in more than 6’ seas nor seen more than 43 knots on this boat so maybe in severe conditions the drains are more of a problem. I am considering a minor change in the drains.  It should be possible to create a baffle that would prevent the entry of any water into the lockers from the drains.  It would work a little like the Aqua lift muffler to block water flowing in and allow any water that did enter to flow out of the drain when the bow lifted.  The twist turns on my bow lockers don’t really apply any compression to the gasket.  Are the bow locker gaskets compressed on the Super Maramu?

Keeping spaces, stuff salt free and dry on a cruising boat is a real challenge,  I completely agree with you.

Best,

James

James,

How do you lay out 100 meters of anchor chain on deck for rinsing and drying without beating the deck all to hell?  I haven't ever figured out a way to do that.

When I had a local fiberglass guy look at my anchor lockers to give a quote for the repair, the FIRST thing he wanted to do was add overboard drain holes to the lockers--which Super Maramus do not have.

I explained that on an Amel, if there is significant amounts of water coming into those lockers, something is wrong. Fix the problem (stop the water leaking in) rather than trying to fix the symptom (draining the water).  In a properly maintained bow locker on a Super Maramu, more water will come IN from an external drain than from any other source.

That doesn't mean the locker will be bone dry. Putting salty wet sails and lines in there will crea te a swamp-like environment, that's a different problem.  Keeping stuff as unsalty and as dry as possible is always a good thing--and much more challenging on a cruising boat than on a boat with a home port.
