SWPS Alexander Mackenzie came up on the random opening screen this morning.  I couldn't see any exhaust flue, and suspected western Canada (miscued by Mackenzie River, and an early prime minister).  Not so: it was Ohio River.

The funnel is quite remote from the paddles

...probably 'doing this to death' here but I found a few more pics of boats that have escape pipes not condensers...

I must check Kiwi here, Rawhiti was 190' B.P.203' length on deck and another 23' over the fantails. The boiler is carried as far foreward as possible for trim as it is easy to bog the wheel down and makes steering much easier and responsive.Just keep her head down and bum up. There are or were pics on here somewhere of a boat down on the Murray stated as the slowest thing afloat (diesel powered) with her bows pointing to the sun, I bet if you trimmed her down she would be a different ship.The engine exhausts generally had a cutout directly overboard so when starting from cold the condensate was blown straight out but after warming through exhaust steam was gradually bled to the funnel line and up the stack, and on the waikato boats, when the funnel was lowered for bridges the exhaust was sent back thru the o/b discharge. I really don't think the engine crew were considered at any time but the firebox and bunkers foreward made most sense when you nosed into the bank and wooded up.I don't know of any woodfired boats in N.Z. only coal burners but they were still bunkers foreward.

Thanks Ray for the correction. Slip of the finger, while half asleep. (which is nearly all the time at present).
cheers

no sweat mate, on your drawings of" Manuwai" in waikato style you may want to include the towing mast and engine frame extensions allowing two more rudders aft of the wheel, these were post 1928 mods when "Free Trader " was stripped down to a barge and was to be Manuwai's dedicated companion. Also she had staggered floats. This stopped wheel slap and vibration. And if Roderick reads this, the "Rawhiti" worked between Port Waikato and Hamilton, designed principaly for trans-shipping general freight from Port Waikato but also as a tug, I have seen her with up to 5 barges alongside.Manuwai also spent her final years as a push tug.

Hi Ray,
Thank you once again. I will certainly have to do a bit more research and add the mods to Manuwai. Will be doing drawings for the Rawhìti2 next year, as well as the Freetrader. Measured them both up earlier in the year, and will be doing so again in the new year to fill in the bits I missed.
