Zar mini dinghies corroding???

[landonshaw]

Does anyone have a Zar aluminum bottom dinghy? I am looking at the 9 ft. Flat bottom aluminum bottom. They might all be aluminum, I don’t know.

I am in the Caribbean and it is in the water year around. My concern is will the aluminum subject to corrosion? The person selling it, new, is saying that the marine grade used has more zinc so it is not subject to corrosion.

Please let me know only if you have experience with this brand. I am well aware of aluminum corroding in salt water.

Thanks
