In homes, what's called a Class-A stainless steel chimney (insulated) is
used to go through the roof and beyond. As to protecting the roof panel,
metal sheeting on standoofs is an idea.

Could anyone please give me the safest way to take the smoke stack through
the roof of the boat.
There will be about 4 ft. 6 inch from the stove to the roof panel, so it
could be a bit hot, understatement.
