My new speed steam boat project
« on: May 08, 2021, 02:10:42 pm »
Bonjour,

I like Hit & Miss engines indeed and, even if I am waiting a new Microcosm M19, my passion is for steam boats.

My previous boat having been badly beaten  :(

I embarked on a new steam speed project with improbable elements, a 60 year old Chris Craft hull rescued from the trash, a double burner Babcock boiler that weighs two arms and a very powerful speed machine, luckily.

Before :

Here is her first test:

I still have some work to do to get her maximum  ;)

Very nice. 

I have an old wood Chris Craft boat here somewhere.
I should try running it in the bath tub.

Looks like a Speed Demon Raphael.

What type of prop will you use?

Woe is me

Bonjour,

Charlie, This first test was done with a 2 blades 60 mm offshore propeller, I will try a 67 mm, then I will buy 3 blades 60 and 67 mm ones and measure the results with a, emectronic tachometer.

For my gas fall of pressure issue, I will convert my tank to liquid phase.

My best "ennemy" runs at about 12 km/h, 6,5 knots, this is the speed that I want to exceed as much as possible  ;)

Bonjour,
I have solved my loss of power issue by using the gas in its liquid phase :

I have to find different propellers for the tests I can't wait to start !

Bonjour,
My Scott boiler is too heavy, I have bought another one which is twice lighter and I hope as efficient :
