Amazing Bert... I'm not really a "boat" guy but that one is truly unique and wonderful!!!
Its funny how so many of us had similar starts - My "engineering career" started with a Mamod engine. Just looked them up and can't believe what they go for now!
I was quite young and wasn't suppose to be firing it up when my Father wasn't around but did so regularly. Got caught once and had trouble sitting down for a few days
Before I switched to aircraft maintenance I ended my "steam" career as an operator of a 52MW General Electric Backpressure steam turbine generator and a 22MW Stal-Laval. The Stal was an amazing machine.
