Sorry, this is not a boat building question, but this is probably the
group that more likely has old wooden boat buffs than any other I could
find.

I have a question about the 1887 tugboat "Rustler", located in Puget
Sound, still working as of 2001. What is her hull made of? Iron or
wood?

And if you know her, is she still afloat?

Thanks in advance for your help.
