New project: Steamdriven speedboat

(1/7) > >>

Hankwilliams:
Dear friends and neighbors,

I started a new live steam project: A steamdriven speedboat, again not a paddler - but rather interesting. I don`t have any plans, but two rather blurred historic pictures, made by Escher-Wyss & Cie shipyard in Zürich in 1909. My model will not be an exact build, but more a form of connexion to the original boat. Scale is approximately 1 : 10. Hull has sharp and elegant lines. The boat will get a strong boiler with 3 - 4 bar pressure, two flametubes and  gas - steam regulation. I`m considering about the steam engine - possibel would be a Regner Neptun, perhaps a Stuart D 10 or a Chinese Kacio engine, which made good impression. Lenght of hull is 1560 mm, breadht 225 mm. I hope, deplacement will be below 10 kg.

That look's a really interesting project. I am always motivated by models that have 'ram' bows although I suspect in this case the bow projection may be a speed improving bulbous bow?

Hankwilliams:
I think, it`s more a speciality of Escher Wyss small steamboat design of that time than a real blbous bow. There is the "Seekadett" and the nice design of "Tivano" of the same epoch, which also show this ram bow. Probably it`s more a matter of fashion than the attempt to improve speed.

Spankbucket:
Yes Thomas, I think your are right; these bow designs seem all part of the 'ram bow' naval philosophies of the time for all designers of ships.

Well Thomas...the Regner Neptune as we know is superb, the new Chinese Kacio LS2-14 twin also looks absolutely brilliant in the representation of a true full sized engine, and all for an attractive price

I have no soft spots for the D10, as being lumpy ...the examples I have seen do not want to start smoothly :shhh :ranting

We,  :gathering .....shall look forward to your engine decision
