Re: Two cheapo material questions - galvanized solar/radar arch and ext plywood sole/
It's best not to have any sort of mild steel on a boat. If it's magnetic, leave it ashore - steel boats excluded of course.
Good quality exterior ply works fine inside boats, especially if it is epoxy coated. It is particularly important to ensure the edges are sealed. I've used it any number of times with nary a problem.
My current 36 Y/O boat has an interior constructed largely of it, much of it not even painted (yet) in the hidden areas and there are absolutely no problem areas.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
