I have only seen a grounding copper in the stern lazarette on my 1990 Santorin SN24 and that is primarily for the SSB. Ric Bali Hai Stuck in Annapolis

Goog day to all . It seems to me that the bonding is s very important thing for the survival of our boats. How could you to do to get an official response of the yard AMEL on this? There is an after-sales service of AMEL?? Greetings

Hi sailors, Just out of curiosity, does the bonding strap in the bilge attach to the rudder zincs? I can see it bonding to the keel, but how does it (if it does) go from there to the rudder? If not, where does it go from the keel bolt in the bilge? If it doesn't go from the bilge to the rudder zincs, is it a way to get the keel bonded to the zincs via another route? If so, what is that route to the rudder? Duh, Kent SM243 KRISTY

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" Bill Rouse

After two years in the water (fresh) I see very little degradation of the zinc on the rudder. I would expect some , never have seen much . Should I be concerned that it is not connected somehow and not doing its job. Thanks, Pat

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. Bill Rouse

Good evenig, in the fresh water (conductivity < 0,1 Siemens/meter) we use magnesium based anodes, such as those the water heater. Greetings.

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?

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. Bill Rouse

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 Kent SM243 KRISTY

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.

Last we 've found on my Santorin the ground strap linking the bonding wires to a keel bolt. The copper strip is on the starboard side of the bildge on the back of the bildge suction pump FEIT. The bonding wires (yellow/green) should be connected behind the noice insulation. I think will be good to see, remove the float tube and the suction of the pump. Could someone give me some guidance???Thanks to all and greetings. Enio

good morning, ameliens. I have the need to change the ground strap and ask who did it, how do I remove the bildge float switch assembly from the well???? Tanks

I will answer you as to how it is done on a Super Maramu 2000. Also, you should review the photos at: Removing the bilge sump float switch assembly, cleaning the bilge and hoses:

On Cream Puff (you do not state your Amel type or hull number), the float switch is remove by disconnecting the power supply and pulling the large tube aft out of the clip-in bracket. It is very easy to remove. I take it out when cleaning the bilge.
BeBe has some awesome instructions for replacing the ground strap: https://groups.yahoo.com/neo/groups/amelyachtowners/search/photos?query=ground#zax/albums_138287824

Thanks guys. Here's another reason to choose AMEL. I go down to the cellar to work. Hello. Enio

The only thing I can add to a very great explanation of cleaning the bilge is that I purchased a long handled brush that is used to clean cobwebs from ceilings. The bristles are strong and the handle is quite long. It can be used for about 2 cleanings before it is too gross to store. So far it is an excellent brust as the handle is quite long.

I used the pictures of Bill and gave them to a mechanic in Kusadasi Turkey, who was able to do this job following the same procedure.
I also used the same thickness of the copper strap as Bill used but have no scientific expalanation of which thickness to use. The old one was completely rotten away. Rink de Haan Razor's Edge Sm2K #330

Sometimes the zinc is installed over painted bottom which would also block conductance between the zinc and the rudder. On my SM I have sanded the paint off prior to installing the zinc.
