AB Inflatables (or any aluminum) - Zincs??

Hi All,
I was hoping for advice regarding AB aluminum RIBs… is anyone adding zincs to avoid corrosion/galvanization? I've read some things that suggest you should. I have a new AB A10AL (unpainted) and want to know about this (or any other necessary maintenance), if others could offer their advice.

Do you add/use zincs? Where do you put them?
Do you condition the aluminum in any way?
Any other things I should do to keep my new dink looking good?

Thanks, Paul

Re: AB Inflatables (or any aluminum) - Zincs??

We just purchased an aluminum RIB. We went with the highfields which is a powder coated aluminum hull.

My theory on this subject is that you don't need it. There will be no electrical connection to the boat and with the engine out of the water it will be only one type of metal.

I hope someone else will chime in.

Our Gemini RIB has now been in the water essentially full time for 9 years. It's powder coated hull has numerous scratches and dings reaching down into the metal. There are no signs of corrosion anywhere. We use no zincs or other means of protecting the aluminium. It is on its second set of tubes, and will soon need its third (the first were burned up by the mongrels who stole it when nearly new).

The hull, which is actually made by Swift in Australia, has exceeded our expectations and seems essentially bulletproof (metaphorically). If we were to need to buy another, I would definitely buy one with such a hull.
