Love your launch, Bart! It seems to me that I've seen a version of that with a smaller steam engine up here in one of the antique boat shows.
Infinitely more practical than an oil-powered one around the Ontario lakes in the late 1800s and early 1900s when they were popular, IIRC: lots of trees, not so many oil wells on our lakes then.
This is like the ones I have seen.
[Edit: I have taken us right off-topic. Please forgive me, and allow me to suggest that we go back to the actual topic]
