No. Aluminum is very reactive. Corrosion will occur for a multitude of reasons. It is almost unavoidable and when it does, it is
FAST, but ultimately the scantlings of any boat is a product of size and hull design. Your comment of .125" as heavy duty, that
true if the boat doesn't exceed 18'.

I find it interesting that a lot of the small boat aluminum designs seem to say the main hull should be 3/16 and yet .100 is used
in a heck of a lot of commercially available small boats. .125 is considered heavy duty. Is it just CYA?
