Re: [Amel Yacht Owners] SM Jib Furler Failure.

That makes sense, Bill.  Guess I was thinking of sea water on furler, deck, hull all interconnecting as if submerged.

So the furling motor is not bonded to the zincs?  What about the bow thruster?  If have sworn they were both connected via the yellow/green wires.

I'll be back aboard next week and look again.

Bonding would have no effect on corrosion here. The zinc that is attached to the bonding system has to be in the same “body of water” as the metals it is protecting.  In this case the “body of water” is the tiny little puddle between the stainless steel screws and the aluminum plate. It is its own little battery, and connections to the rest of the boat are immaterial. These stainless screws seem to have been the focal point for the corrosion on my piece.  

Other than disassembling the furler unit, this is an easy fix.  The plate is just a round piece of 1/4 inch aluminum with four holes in it.  If I was in a remote place, I could make it on the boat with hand tools.

While I have things apart, I am taking Kent's suggestion and finding a local powder coat shop to have everything made pretty… hopefully for much longer than paint.

I don't know if the furler on Kristy is connected.  Sure seems like it should to sea water, dissimilar metals.  Wonder why it wouldn't be?  Anybody else know if their furler is connected?

Hello Kent,

None of the rigging on my SM is attached to the bonding system.....
