Rusting anchor chain

Anne and John Hollamby <annejohnholl@...>
 

Mixing metals in sea water creates electrolysis and thus rust.Thus a stainless anchor on a galvanised chain will cause the chain to rust.I have a galvanised anchor fixed to a galvanised chain with a stainless swivel.The chain is protected  by fitting an anode on the end of the chain which has not rusted despite about five years use.The anodes that I use are designed for propshaft use, from memory 1.5 inch diameter and are fitted around the chain. They are not a perfect fit but do the job especially if the bolts are tightened from time to time. I shall change the stainless swivel to galvanised anyway as wrought iron is stronger than stainless thus the idea of using a stainless chain is not very smart.

I have an actual cooler, but I also have a Yanmar and a later model SM2k. There are photos of mine at: https://groups.yahoo.com/neo/groups/amelyachtowners/photos/albums/1228643648

Re: Interlux micron 66

yahoogroups@...
 

Pat,

Absolutely correct. Here in Europe they distribute Micron77 which is good in fresh or saltwater.

I do not think Micron77 is available there.

BTW, I did not know you were in fresh water until your recent anode post.

Volvo transmission cooler

Patrick McAneny
 

I took the hoses off the transmission cooler on my Volvo TMD22A . I expected to see a coil or heat exchanger inside of the box , but it appears there is nothing inside from what I can see. Is it simply a heat sink , water passing by the side wall of the transmission pulling heat away, or is there a coil with oil passing through that I can not see by looking down through the top where the hose attaches. I do not want to take the box off the transmission for nothing. Thanks, Pat
Interlux micron 66

Patrick McAneny
 

Based on the positive feedback from members of the group and the evaluation from Practical Sailor , I was ready to buy and apply micron 66 to my boat. An employee in the yard said he did not think I can use it because I am in fresh water, but he was not sure. I contacted Interlux and confirmed , that you can not apply micron 66 if your boat is going to be in fresh water for more than 24 hours. The fresh water destroys the paint's biocide. This happened to a good friend, that did not know why , but the micron provided no protection while he was in the Caribbean last year after applying here , two months before leaving . I told him why, yesterday after talking to Interlux , and I thought I'd pass it along to the group so someone does not make the same costly mistake that I almost did. I have decided to use Sea Hawk Biocop , which is supposed to be very good for fresh and salt water.   Pat SM Shenanigans
Re: [Amel Yacht Owners] Re: Santorin ground strap

rossienio@...
 

Good day Kent, is clear to me that the cast-iron keel (iron+carbon) is not the end of sacrifical bonding, but itself must be protected by zinc on the rudder. 
But i cannot tell if the keel on SANTORIN is connected to the bonding or not.And if it is relared how????????  Greetings. Enio.
Re: [Amel Yacht Owners] Re: Santorin ground strap

Kent Robertson
 

I'll check when I get back on the boat and see if I can follow a wire to the rudder.  There has to be one since my zincs are eroding enough to need replacing every 6-8 months.

The bonding strap is there to prevent damage to the keel, not as the final termination of the bonding system....right?

Sigh...maybe I'll understand it all one day.

Thanks again

I do not think that is accurate for 387.

I am mostly sure that all green/yellow wires terminate at the ground strap,  and that there is a green/yellow wire that connects the ground strap to the rudder post which is connected to the zincs.

There is a copper foil buried in the hull, but it goes to the SSB ground on the skeg.

That answers my question, thanks.  So the keel is bonded as is everything else, to the zincs via a large green/yellow wire that connects to the zincs via a strap that's buried in the hull epoxy.  That sound right?

Kent,

Look at the top of the ground strap on your SM. You will see the attachment of all of the yellow/green wires from each of the items that are "bonded."

One of those wires runs back to the stern and is connected to the rudder post and zincs.

The bottom of the ground strap is connected to a SS  keel stud, secured by a large SS nut...30mm if my memory is correct. To loosen the nut, you will need about 3 feet of 1/2" drive extentions and a 30mm socket. There are photos. Search photos for "ground strap"

Good evenig, in  the fresh water (conductivity < 0,1 Siemens/meter) we use magnesium based anodes, such as those the water heater. Greetings.
Re: [Amel Yacht Owners] Re: Santorin ground strap

Bill & Judy Rouse <yahoogroups@...>
 

Pat,

Here is what I have done:

In the water I used a meter to check continuity between the termination of the green/yellow wire on the rudder post to the top of the ground strap where all of the green/yellow wires connect.

Out of the water, from the zinc back to the top of the ground strap.

I have no experience with fresh water and zinc deterioration, but have heard that aluminum is used for anodes in fresh water. Ask some of your fellow fresh water neighbors about this.

The bottom of the ground strap is connected to a SS  keel stud, secured by a large SS nut...30mm if my memory is correct. To loosen the nut, you will need about 3 feet of 1/2" drive extentions and a 30mm socket. There are photos. Search photos for "ground strap"

Thanks Craig. But I doubt remains about this bonding is connected to the keel. Or as the keel is connected to the zincs. Because I cannot see any eart attachment point near the bilge. I would expect to see some green/yellow wires connected somewere. But I dont see anything, while the connection through the ground strap is clearly visible on the SM (see photos of Jrjrjrouse, 2007).  But if the keel is not connected I have to put zincs on the keel? Now I'm in Italy, but if I go to Greece I will go certainly Leros.  ciao. Enio

Hi Stefano,
We regularly do the service for trasmission and bague d'usure every two years. The task is done by our engine mechanic who learned the tricks seven years ago when we bought our baby.  We are based in cala de' medici south of livorno, italy.

Good afternoon, I do have same request but further EST, I'm based near La Spezia Italy, I did already bow thruster and engine (oil and fuel filter). It's time for the transmission but I'm not ready to do by my self. I'm starting to have some problem with elettronics as well like Interphase Eco. My SM is hull 185 October 97
Thanks for any recommended name

Good morning,

Does any one has recommendation for very experienced person or shipyard with the Amel Transmission on the SM2K in Fort Lauderdale?

I just need it to be serviced (changing the bague d'usure, seal, oil, etc.).

I have never done it myself, I would prefer pay and watch someone very familiar with this, rather that possibly make an error myself.

At the same time, will also have:

propeller rebuild,
antifouling,
Wax hull,
Bow thruster services (which I can do),
Bauer scuba compressor serviced,
water maker serviced,
Volvo engine check (Turbo issue)
grease forestay
Espar heater serviced
add a second freezer,

So any recommendations for these are welcome as well.

Thanks in advance, Alexandre

Re: Santorin ground strap

Craig Briggs
 

Rossienio,
On my Santorin #68 (1992), and likely most, if not all, Santorins, and I suspect on SM's too,  there is a very heavy gauge green/yellow grounding wire connected to the rudder post assembly. It is thereby electrically bound to the steel frame structure inside the keel to which the zincs are bolted and that is the main sacrificial anode for the boat. This wire goes a few inches forward and is bolted to a wide flat copper strip that then disappears into the top layer of the hull's fiberglass.  That strap travels forward throughout the boat to pick up the various grounds from rigging, "C"drive (and thus the prop) and thru-hulls.  The cast-iron keel is not the sacrificial anode of the boat!  It's not even a good ground since it is (or should be) well epoxied and painted and thus insulated from the sea water.

The corrosion you see on your keel is indubitably the coating on the cast iron keel failing and plain old rust is showing through.  Time for a proper sand-blast and epoxy job per Joel's fine instructions posted a few times on this forum.

If you're in Kusadasi I'd recommend you scoot over to Leros and have it done by Agmar Marine in their Leros Boatyard on the north end of the island next to the airport. Tell 'em I sent you for a free ouzo. They are very experienced doing this and I had mine done with excellent results, with immediate coating after sandblasting, plus fairing and moisture barrier. Regardless of where you have it done, do observe the process to be sure the bare metal is coated immediately.  If not, make them do it again!

Cheers,
Craig Briggs
