NOR'WEST SHIPPING TRADE.
Western Mail, Perth, Saturday 20 February, 1909.
ADELAIDE COMPANY'S NEW
STEAMER.
(See Illustrations.)
The Adelaide Company's new steamer
Koombana, which arrived at Fremantle
last week on her maiden voyage from
Glasgow, has a special interest for the
Western Australian public. She is the
first passenger and cargo boat that has
been built exclusively for service on the
Western Australian coast. Her mission
is to develop the Nor'-West trade. That
she is admirably adapted for this purpose
is beyond question. During the last few
years the Adelaide Steamship Company
have made several additions to their large
fleet of inter-State vessels, and in the
Koombana the acme of perfection as
regards the comfort of passengers,
facilities for handling cargo, and appliances
for skillful navigation find expression.
Several gentlemen interested in the
shipping trade who at the invitation of
Mr. W. E. Moxon, the company's general
manager in this State, made an inspection
of the steamer, marvelled at the courage
of the Adelaide Company in placing such a
fine boat in the Nor-West trade. It is tangible
evidence of the recognition of the growing
importance of this service, and that the
travelling public and those interested in
the development of the great northern
portion of the State will appreciate the
enterprise of the Adelaide Company goes
without saying.
The Koombana is a steamer of 3,760
tons register, and was constructed by
Messrs. A. Stephen and Sons, Ltd., Glasgow.
She is equipped for the carriage of passengers,
cargo, and stock, her dimensions being
340ft. between perpendiculars,
46ft. 2in. beam, and
20ft. 8in. in depth.
According to this report Koombana's depth was 20 ft. 8 in. and draft, 19 ft., which gives us a freeboard of 1 ft. 8 in. which is impossible. 20 ft. 8 in. refers to her maximum draught. We shall have to be very cautious of specification figures presented by the Press. Inquiry transcript gave:
3668 gross tons
2182 net tons
340 ft. length
48 ft. 2 in. beam
25 ft. 8 in. depth (of hold?)
4000 ihp
20 ft. 8 in. draft (wikipedia)
On a draught of 19ft. she can carry 4,000 tons of cargo.
4000 tons suggests loading ALL cargo 50 cubic feet to the ton and displacing livestock from the cattle deck, which is not only unrealistic but would yield a draught well in excess of 19 ft.. Normally 100 cubic feet to the ton overall loaded, suggesting 1,800 tons cargo generally transported.
4,000 tons was a 'pipe dream'.

4,000 tons was a 'pipe dream'.
The previous post's report suggested a depth of 32 ft. which allows for a double hull space of about 6.5 ft., which seems excessive for a steamer of this size - should be more in the region of 3.5 ft., similar to Yongala.
Elevation plans for Koombana demonstrate the following dimensions:
1) Depth of hull - 29.5 ft..
2) Ballast tanks - 3.5 ft..
3) Depth of hold - 26 ft..
4) Draught - 20 ft. 8 in.
5) Freeboard - 8.55 ft..
6) Propeller - 16.5 ft. (top to bottom of hull)
Koombana had ballast tank capacity (in the double bottom) for 900 tons, whereas Yongala's ballast tank capacity was only about 400 tons, which in part accounts for the differential. (Having perused the plans for Koombana her double bottom depth was the same as Yongala's, 3.5 ft. and the differential in ballast tank volume was made up by massive after and forepeak tanks, which were manipulated to access the tidal ports.)

Furthermore, Koombana operated with a freeboard of 8.55 ft., which is correct for a ship of this size.
It is very important to note that this juncture that the propeller was 16.5 ft. from bottom of hull to its upper limits. This has great significance for what was about to come in a disastrous future.

If one compares Koombana with Yongala - both Adelaide Steamship Company:
Koombana (1908) Yongala (1903)
gross tons 3668 3664
net tons 2182 1825
length 340 ft. 350 ft.
beam 48 ft. 2 in. 45.2 ft.
depth (of hold) 25 ft. 8 in. 27.2 ft.
hull depth 29.5 ft. 30.5 ft.
draft 20 ft. 8 in. 24 ft.
What becomes apparent are the marked similarities between the two steamers, particularly with regard to specifications and prominent top hampers. However, Yongala's narrower beam would likely have improved stability marginally compared with Koombana's wider, flat bottom and it is patently clear that Koombana operated with a significantly reduced draught (related to Northwest coastal ports access); a differential of 3.25 ft.. This would have had a significant impact on reducing GM stability and although both steamers were visually top heavy, Koombana took the prize in this department!
In her design special attention has been
given to the fact that she will be engaged
in a semi-tropical trade. Her decks are so
many that a lift is almost required for
transit purposes. Above the lower hold is
the orlop deck, on top of which is the main
deck. Higher up is the spar deck, on which
the bulk of the passenger cabins and the
dining saloons are situated. Over this again
is a fine promenade deck, and going still
higher the bridge and boat deck is reached.
On top of all is the navigating bridge.
The manner in which this paragraph is written suggests surprise and awe at the number and height of the respective decks. Bearing in mind this was 1909, a significant top hamper on a coastal steamer was 'uncharted waters' and rather daring - or unstable?
Again I am not sure that the classification is entirely accurate; the main or cattle deck was in effect the spar deck (the uppermost, continuous throughout length, steel deck within the hull) with the shelter deck above that; promenade or hurricane deck above that, and finally bridge or boat deck above that.
Accommodation is provided for 300 first and second
saloon passengers. Most of the cabins contain only
two berths, and the appointments leave nothing to be
desired.
All the first-class staterooms are constructed on the island
system, each division having a separate entrance from
the deck, while easy access is obtained to the saloon.
Electric fans are fitted in each cabin. The drawing and
smoke rooms are located on the promenade deck, and
both are handsomely appointed. Special attention has
been paid to the colours of the upholstery, an effective
scarlet shade predominating in the smoke room, while in
the social room a harmonious and restful tone is produced
in purple (a matter of opinion). The social or drawing room is
fitted with portable lounges, and furnished in Waring and Co. 's
best style.
The walls are treated with sycamore, the panellings being
executed in satinwood. At one end is an elaborate bookcase
with mullioned frames and bevelled glass, and containing
an up-to-date library, and a Broadway piano, two
Chippendale writing desks, occasional tables, electric
fans, etc., are also included in the furnishings. The
ceilings are composed of white painted canvas with
gilt-edged floral design. The main entrance to the
saloon is handsomely panelled in mahogany, and
the stairway leading to the promenade deck is of
the same material, with carved pilasters. The dining
room in the first saloon has seating accommodation
for 75 people. It is roomy, and well ventilated, and the
oak panellings and green upholstery give a quiet but
withal pleasing effect.
In the culinary arrangements every detail has been well
thought out. The most up-to-date appliances are provided
in the galley and pantries, a feature of the kitchen being a
patent electric egg boiler, by means of which an egg can
be boiled to suit each individual's taste - soft, medium, or
hard. In the bake house an electrically driven dough
mixer is fitted up and 300 loaves a day can be turned out
if necessary.
Ample bathroom and lavatory accommodation is provided
and generally speaking, the fittings throughout are of first-class
description. The ventilation throughout the vessel has been
very carefully attended to. On the main deck (spar), running fore
and aft of the vessel, excellent provision is made for the
carriage of live-stock - an important branch of the Nor' West
trade. Besides the ordinary space for stores, refrigerating
chambers are fitted up with a capacity of 1,800 tons of cubic
space. With the exception of one steam crane at the No. 1
hatch for'ard, all the cranes are worked by hydraulic power.
Clayton's fire extinguisher and fumigating plant is carried on board.
Cattle on the deck below such opulence must have created significant compromise in warm weather. The Clayton device, from what I understand, used a principal of suffocating fires - starvation of oxygen. This did not of course deal with smouldering fires deep within coal piles or cargo. 1800 tons of cubic space for refrigeration seems excessive (probably total) and precludes normal cargo. Will have to cross-reference this.
The navigating appliances are of the very latest and most
improved design. On the bridge are a variety of instruments
and machines undreamt of in the earlier days of steam navigation.
There is Alfred Graham's patent telephone switch, by means of
which the officer on watch can converse with the captain in his
cabin, the engineer on duty in the engine-room, or the officer on
the poop.
An indicator is provided by which automatically and silently
directions can be given to the officer right aft when the
vessel is being moored or leaving the wharf; a further
indicator shows the exact position of the rudder, while the
steering gear is controlled by a telemotor, the latest device
for the safe navigation of a vessel. Electric sidelights, with
auxiliary oil lamps, are provided, and should any of the
navigating lights at the port or starboard side or at the
masthead become by any means extinguished, an indicator
gives immediate warning to the officer on the bridge. The
officers' quarters are all conveniently situated.
Very impressive technology for 1908. One wonders if such new technology had a downside in the form of questionable reliability - appliances malfunctioning or failing at sea - particularly in a storm?
The Koombana was brought out to Australia by Captain J.
Rees, late of the s.s. Bullarra, and he will retain command
of the new vessel. The steamer left for Melbourne last week to
be docked. According to present arrangements she will then
return to the West, and leave Fremantle on her initial trip to the
Nor'-West on March 12.
It is interesting to note that the vessel derives her name from
Mr. R. Forrest's "Koombana"" timber mill, near Bunbury.
Koombana was launched 27 october, 1908 and entered service, February, 1909.
