New 175 am alternator
Dear all!
we bought our OYA, a SM 2000, 373 in April. now we want to change the alternator to a bigger 175 amp. 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? thanks for your ideas, tips and experience Stefan SV OYA, SM 373, Carriacou / Grenada

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. KAIMI SM429 2004 Redline Emeritus BRITTANY DE LA MER SN86

Re: A question about coppercoat
ianjenkins1946 <ianjudyjenkins@hotmail.com>
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.

Re: A question about coppercoat
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.

Re: A question about coppercoat
From my point of view, the elementary problem is that you still have to go to the crane every year to clean it and grind it again so that it works.
toggle quoted messageShow quoted text
Of course, this increases the costs if you don't want to get out of the water every year. My personal recommendation for those with long water times is still the tried and tested antifoulings for 2 or 3 years (Micron, Seajet ..). This form may be helpful for yachts that do not have epoxy protection under water from the shipyard. My personal question is always why is it not used by commercial shipping?

Re: A question about coppercoat
CopperCoat has been the least expensive antifoul I’ve ever used. Spread that “high” cost across 10 or more years.... Matt ~~~_/|)~~~ A50#27

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. ~~~⛵️~~~Matt

Re: Bow Thruster Amps rating.
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:
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).

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. Chris

Re: A question about coppercoat
Patrick McAneny
Matt, How many coats of CC do you apply. I am fairing some holes in my gel coat and then plan to overcoat with Interprotect 2000. Can CC be applied over a barrier coat?
Thanks,

Re: A question about coppercoat
We applied CC ourselves.
toggle quoted messageShow quoted text
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. ~~~⛵️~~~Matt

Re: A question about coppercoat
Ian Park
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.

A question about coppercoat
Ruslan Osmonov
Hi Pat, check this out https://youtu.be/6JkCzOZ9k_Q they had few failures, but at the end worked out. Good summary on things to watch out for. They have few videos on their saga with copercoat, this is the last one when they finally made it work, if you up for it and have time.
