Re: New 175 am alternator

CW Bill Rouse
 

Stephan,

175 amps of 24 volts is a lot, but if you do change to a bigger alternator, you will likely need to increase the size of the wire from the battery bank switch to the 24-volt alternator. You will also probably need to change belts and pulleys. I really loved the fact the on the Yanmar engine all 3 belts were exactly the same.

Additionally, if the Leece-Neville 24-volt, 175 amp alternator is still working, I can think of several SM owners who will want to buy it. It is very difficult to find an alternator with that high of amperage and that is built as good as the Leece-Neville. Let me know if you want to sell it and I will pass the information to those interested.

Dear all!

The engine is still the original Yanmar 75hp from 2002.

Is there anyone with good experience with a special brand?
Do we have to pay attention to something when converting?
Which alternator fits this engine?

Maybe I missed it but does the ability to put 12 lithiums in our SM Redline models solve the high amp problem?? In theory the 4 extra 31 series provide 50% more amp capacity.

Somewhat related.  On our Santorin we had a 250 amp fuse for everything coming out of the 12V battery bank (ABYC requirement at the time).  It was installed in 2003....Blue Sea, probably slow burn but we never had an incident in 10 years of operation.  I think the bowthruster was also rated 10 hp (correct me if this is wrong) so probably drew some high amps at 12V.  

I've posted this before but in about 75%+ of our bow thruster manoeuvring we are not in gear and have a habit of high idling our 175amp-24V Leece-Neville--probably feeds a minimum or 75amps into the system and helps to keep the voltage up.  Only problem is that people who might  be helping you dock can panic if they think that you are in gear.  Also have to pay attention to the salt water spitting out from the engine.  Also, I am guessing that most of us do this, but we also are at high idle when we use the windlass--whenever we are coasting or doing the final vertical anchor pull.

Hi Dan,

I certainly will share what I land on here..  Also In the Class-T vs ANL. The Class-T max out at 400A  (what you have and seems to be working).    
I chose ANL due that I can put one on at the the Amp rating that will match the bow thruster (thus my original question of this thread).  I guess I will find out if it blows!  It seems here there is not a write or wrong- but it is good to see others being safe as well.  
Here is a good guide I found to fuses, use, and sizes.

Hi Arnold,

 We have had no need to clean and grind Coppercoat in the ten years that we have had it  , other than occasionally wiping off slime after a few months which we can do swimming.

 Have a look at the Coppercoat website--I think you will find that their major market is commercial vessels, oil rigs etc  They know about long water times and the huge cost of taking vessels out of use for maintenance.

We have hauled every hurricane season to store our boat. CC is a hard epoxy. One nice feature is, when cleaning slime, you can take a 6” metal putty knife to scrape it with no ill effects. Straps won’t affect it. No worries.

Yes, CC can be applied over barrier coat. Follow their directions.
I applied four coats as they directed. The coats go on thin and it doesn’t look right until the second or third coat.
I can’t over emphasize following their directions to the letter.

Confirm what others have said. We usually get a layer of slime in tropical waters, less so in colder northern waters. It comes off easily with a nylon abrasive pad, or with jet wash on a haul out. If you get shell a scraper works very well.
I share Pen Azen’s ages and comments. When you’ve done the anti foul cycle enough times it’s a joy to have a Coppercoat.

Re: Bow Thruster Amps rating.

Dan Carlson
 

Hi Chris,   Please share pictures of how things look after you “unstack” the main switches.  I have been considering that as well. 

 

Here are a few responses to your ideas: 

  1. I would prefer to leave the very heavy bow-thruster cables as is on the Main switch.  I don’t want to add anything in that heavy load circuit that I can avoid.  
  2. I read a few concerns about ANL fuses for heavy load circuits and recommendations to use Class T for those.  I have one 400A class T from Blue Sea on the positive battery cable.  The inverter/charger, solar MPPT etc are also fused separately (200A ANL on the Victron Multi-Plus 3000/70/16)

 

Would also be interested in more information on where you mount and how you wire your rotary switch when you get that installed.

 

Thanks and regards,  Daniel and Lori Carlson on sv BeBe, sm #387

Thanks everyone!  My setup has me in 4 groups of 100AH 12V Battle Borns @24v (400AH).  I have each group's positives and negatives aggregating to corresponding bus bars that then lead to the battery box posts.  I have an AMP ANL-style fuse holder in-line on the positive bus bar.  Everything I touch on this boat is going to be fused / breakered out appropriately.  I'll start with the 500amp and move up to 600 if needed.  

 

Bill Kinney- basically doing what you have done with your 24v / 12v distribution. I am going to work backwards from distribution and  "Unstack" the main Amel switches and move all the cables to bus bars (4 of them Engine Pos, Engine Neg, House load Pos, House Neg.) proper fusing closest to distribution and breakered out for switching. Same goes with any of the 12v distributions. All with appropriate marine wire, fittings, and labeling. 

 

On the AC side I am removing the Amel Auto Priority Gen / Shore Power priority switch (yes it has severed her well so far) in favor of a manual rotary Gen-Off_Shore switch..  Just for my peace of mind.

Re: A question about coppercoat

Matt Salatino
 

We applied CC ourselves.
It’s not easy.
First, CC is not paint. It is a 2 part epoxy with copper powder (more like dust) mixed in. Two factors to deal with:
1) the copper does not stay in suspension. It must be mixed constantly. This takes one person.
2) it’s epoxy. If the weather is warm, you have limited time to apply it before it “kicks”.

The constant mixing on a warm day insures a relatively short working time before it hardens in the paint tray, so you must mix many, small batches, and work fast.

Lastly, and very important, you must let the CC cure for 4 days on the hard, then sand it. Any epoxy will coat (encapsulate) whatever particle is introduced. Unsanded CC is not anti fouling. You must sand it to expose the copper metal for it to be antifouling. Sanding is a critical step.

There are published directions in applying CC yourself.
The first step is removing all old paint, and having a very clean hull to start. We are members of the yacht club that the US distributor of CC belongs to, so we had excellent technical direction, and followed all instructions, exactly. There are no shortcuts to applying CC.
That said, my wife (the mixer) and I applied it ourselves, doing one side of the hull each day (so two days to apply) and one day to sand, 4 days later. It was difficult, but worth it. We sold the boat two years ago. It’s on its 7th year with no problems.
When necessary to repaint, we will have CC applied again. We’ll likely pay someone to do it.....we’re getting old.

Can coppercoat be applied by an owner or does it need to be applied by a dealer ? If it can be installed by an owner ,what would you estimate the cost of materials would be . I had the impression that there was mixed reviews on this product,but you guys seem very pleased with it. I have my hull down to the gel coat and ready to apply a barrier coat soon ,so I could go with any bottom protection at this point.
Thanks,

Paul,
Confirm what others have said. We usually get a layer of slime in tropical waters, less so in colder northern waters. It comes off easily with a nylon abrasive pad, or with jet wash on a haul out. If you get shell a scraper works very well.
I share Pen Azen’s ages and comments. When you’ve done the anti foul cycle enough times it’s a joy to have a Coppercoat.
PS I think many AMEL owners have often been told its cheating to have all these buttons for furling and reefing the sails - but I’ve done my share of being jet washed on the foredeck and love the comfort of my Santorin (and not having antifoul coloured measles off the paint roller).

Thanks everyone!  My setup has me in 4 groups of 100AH 12V Battle Borns @24v (400AH).  I have each group's positives and negatives aggregating to corresponding bus bars that then lead to the battery box posts.  I have an AMP ANL-style fuse holder in-line on the positive bus bar.  Everything I touch on this boat is going to be fused / breakered out appropriately.  I'll start with the 500amp and move up to 600 if needed.  

Bill Kinney- basically doing what you have done with your 24v / 12v distribution. I am going to work backwards from distribution and  "Unstack" the main Amel switches and move all the cables to bus bars (4 of them Engine Pos, Engine Neg, House load Pos, House Neg.) proper fusing closest to distribution and breakered out for switching. Same goes with any of the 12v distributions. All with appropriate marine wire, fittings, and labeling. 

On the AC side I am removing the Amel Auto Priority Gen / Shore Power priority switch (yes it has severed her well so far) in favor of a manual rotary Gen-Off_Shore switch..  Just for my peace of mind.

We put our own copper coat on in Trinidad, just the two of us. In the heat it did need thinning down. We did a third of the hull at a time. We did not put a barrier coat on as it is an epoxy mixture itself. This was our advice from Copper Coat Uk. If you go on the website you can calculate the amount you need. The main cause of failure is not continuously stirring the mixture during application to keep the copper flakes evenly distributed in the resin. Another cause is not putting all the coats on immediately the previous one is at the ‘tacky stage‘. Sometimes ‘professional workers’ put a layer on the whole boat Then leave the next coat till the next day.
Our friends did their boat at the same time with one person continuously mixing the next batch while 6 people With rollers continuously applied it.
Bottom line is that it is not much more difficult than anti fouling. On the plus side it is water based so cleaning rollers, hands etc it is less messy and less toxic.
