This is a side view of the second large Steam Launch that I built on this type of fibreglass hull.
This steam launch had a Stuart Turner Double 10V engine fitted, driving the propeller via a reversing gearbox similar to the type that I currently manufacture & sell on this website. The condenser can be seen in the centre of the photo, with a lever type condensate drain tap being visible.
The valve & piping sticking up at the side of the boiler was the water bypass valve from the electrically driven boiler feed pump that was fitted to this boat.
