On Friday Chris McMullen dropped me a note to say the 34′ steam launch was now running and had just completed its first sea trial. Chris commented the boat is doing hull speed at about 150 PSI but the boiler should produce 250 PSI, but needs some adjustment as the smoke is as a result of the burner not working properly. The hull floats as per the design and the machinery is all working as it should.

I have included below links to past WW stories on the project. If you are time poor, the 2021 will give you an insight into the project.
