Size of boat and folding smoke stacks

[Leighton]

Leighton, how long was you planning on building the boat? Also it
> would be a mistake not to put monkey rudders on her.

I agree Joe, and there has been some discussion on this point but
from what can be gleemed from the photos of the Manuwai that ran on
our river (and what we are using as part design) she maynot have had
monkey rudders.
The size of the boat will be around 150' x 35' x 18" draft. There
needs to be a shallow as possible draft because of the sand banks
and where the river spreads out and is not as deep.

Joe you stated that if the smoke stacks fold down there would not be
a connector between the two stacks. We have to incorporate fold down
stacks in the design to contend with low bridges.
I envisaged that the two stacks would be lowered hydrolically as one
unit. The Spirit of Waikato name plate would be part of the
connector complete with wrought iron scroll work.
Is there a reason why the stacks have to be lowered individually?
Thanks for your comments

Most were manually lowered with counter weights to make it easier for
a man to lower them. The newer boats have hydraulic ones, but chances
are there won't be the same pressure of lowering the stacks since
each stack would need a couple rams to lower it. There would probably
be a little twisting pressure on a spreader bar plus you have to be
sure there proper clearance for the spreader bar to miss the wheel
house and other obstacles when lowering.

I've watch the American Queen lower and raise hers a few times, and
though they're activated at the same time, one always tilts more than
the other. She has rams on each side of each stack for raising and
lowering, plus she's so big the pilot house also lowers along with
radars and other things. She's really something to watch coming up
the Ohio River. By the way, she's 418 feet long.

Go to http://freespace.virgin.net/tom.lee/contents.htm, follow the link to
What's New and then to the photo of the Lord of the Isles on the Thames to
read a salutary story of what happens when you don't have lowering funnels,
and to see an interesting photo of an ex-Clyde paddle steamer near St Paul's
Cathedral in London

Hi Alistair, Had a look at at that site and read the scipt. I bet it
was painful when they hit. Talk about embarrassment.
Did you notice that most of the boats in the photos had their
funnels on the rake? Makes you wonder if they went under the same
bridge doesn't it?

That was standard for UK paddlers of that era. Maybe the fashion did not
reach the colonies
