The time has come the walrus said"The time has come," the Walrus said,
"To talk of many things:
Of shoes--and ships--and sealing-wax--
Of cabbages--and kings--
And why the sea is boiling hot--
And whether pigs have wings."
extract from the Walrus and the Carpentar by Lewis Carroll
for me the time has come to stop gazing at my belly button and do something about Jessica Ann my first job was removing the superstructure and then clearing below decks. First to go was the the car windscreen motor.
and then the space underneath the wheelhouse.
i now have an engine room 260mm x 110mm and below the superstructure of 460 x190
i have already concluded that a stuart v10 sits nicely but doesnt offer a satisfactory visual impact by itself it has been suggested perhaps a double 10 or even a triple but i dont have the skills to assemble such an engine so it has to be something of the shelf.
lets have some opinions

Great start, just need to figure out an engine.
Heres a non-traditional idea:
The stuart engine powering a generator, charging a battery. An electric motor is the propulsion but its technicly powered by steam  Steam electric boat....

I'd say that was a very traditional idea. It was quite common in real life in the early to mid 20th century. Obviously, they used something a bit bigger than a Stuart!

I have worked on ships like that. They were a little more advanced though. Gas turbine main engines driving alternators with economisers which generated the steam to run a turbine also with an alternator. The power produced drove two azimuthing propulsion pods. A smart system but expensive to run!

There were some, probably earlier than that, which were pure steam-electric. They were steam turbines running at high speed and electric transmision was quieter and more controlable than gears.

an interesting option
and it impressed me when British railways used it in their deltic locomotives. the only deisel locomotive that ever seemed to have any personality to me. Then all too soon the bean counters stuck their oar in and they were gone.
today when i got home from work i played with a few different positions for my boiler the one below seemed the best.
in this position the flue fits inside the chinney stack.

Nice start there David...If that boiler is a Mac steam horizontal..that is a big boat!!!!

Greg, that is indeed a Maccsteam boiler, and the very same one that was once yours! Been back and forth across the Atlantic!

I like how the Stuart looks in there. I guess you'll want at least a twin cylinder engine for self starting though. What goes above that opening on the hull? An engine room skylight with larger-than-scale portlights would look realistic and still allow the viewer to see the steam engine working. I've seen boat modelers hide the electric switch for the radio by mounting it out of sight under the deck and then linking it via a rod to a more realistic looking handle in the engine room area.

i'm putting up a couple more photos to show how it looks open and
with the engine room covered. As you have correctly concluded it will be a bit dull with the present engine room cover so its my intention to change it so the roofline is a skylight.
its just a shame that the impressive boiler will have to remain hidden

How are you going to power the boat? Steam-electric? Or direct drive to the prop from the engine?

still not quite sure in my heart of hearts i'd like to go with a prop straight to the engine i already have the stuart which would have to be a straight connection because of space constraints i have a graham which is small enough to have a dynamo alongside and i have also got my eye on a double 10 its a bit suck it and see at the moment

Ranger, it's a good idea and of course David will do as he pleases, but it seems to me like it's a pretty scale model so if it was mine I'd drop in a scale powerplant. At least a scale-type powerplant. That boat should chuff around like a steam tug, not whir around like a high tech hybrid.
Someday I would like to see a steam/turbine/electric model of a destroyer or something, but that model is a classic tug and deserves a traditional, beautiful recip engine with visible works, not a mass of dynamos and azipods and wires and whatnot.

You know, if you could pull it off, that winch on the bow wold look great if it were steam powered. There are a few stationary engines out there with two oscillating cylinders with gears between them that sort of look like a marine winch engine. Wouldn't that be an interesting feature on a model steamboat?
