STRUCK A ROCK?

Lyons, a steward, said:-"I heard theboatswain say, 'I would not like tobe on this ship in a storm. She wouldgo to the bottom.' I heard the sailorssay they had to fill tanks to get herstraight, as she rolled too much. On thesecond voyage I believe the ship struck asubmerged rock after leaving Adelaide and loosened the plates underneath.
This is a fascinating piece of 'rumour' or fact? It seems strange that this would be the only account of Waratah striking some object after departing Adelaide on her final voyage. Rather than a rock, if this be true, it would more likely to have been submerged wreckage. If Mr. Lyons only got half the story right, there might be another explanation for 'loosened the plates underneath'. We know that Waratah took the ground at the wharf, Adelaide, prior to departure, and that Captain Ilbery was extremely upset about the incident, claiming that Waratah was too large and heavy to be subjected to such forces on her hull. Although most steamers appeared to have coped with this phenomenon, Waratah was unique in respect of size and heavy loading / ballast. Captain Ilbery stated on arrival at Durban that Waratah had sustained NO damage since departing Adelaide, but the wording did NOT include, damage sustained AT Adelaide! In the case of the Koombana which ran aground Shark Bay, Western Australia, significant hull plate damage was sustained but not detected until much later when Koombana was put into dry dock, Sydney. Damage to Waratah's hull might, in the same fashion, have been drastically under-estimated. If the Harlow account be true, loosened plates, fire heat damage, hull stress due to heavy load and ballast, might have created the scenario for the steamer disappearing within minutes after striking the St John reef, Bluff Point. Watertight compartments were intended to keep the steamer afloat if one or perhaps two compartments were punctured. Waratah might very well have sustained a series of glancing blows much like the RMS Titanic rendering her doomed. There is another possibility that due to heavy loading, water tight doors were not able to be adequately closed in an emergency. Speculation runs rife :)

DRAUGHT AND POWER COMPARISONS.

The following comparative steamers all had significant top hampers, but crucially, significantly lower maximum draughts compared with Waratah. Waratah should in reality have had a draught in the region of 27 ft.. But due to inherent top heaviness, this was not possible, resulting in functional overloading (including ballast). Furthermore Waratah was significantly under powered which, taking into consideration her functional overloading and reduced freeboard, was never going to be a recipe for a successful steamer:

SS Otranto:

Let's revisit SS Indarra, a steamer which suffered similar problems to Waratah and had to be materially altered to reduce draught.

           SS INDARRA                                           SS WARATAH:

Engines:     twin quadruple                                     same

Launched:  1912                                                     1908

Gross tons: 9735                                                     9339.07

Length:       450 ft.                                                  465 ft.

Beam:         60 ft.                                                    59.45 ft.

Draught:      32 ft.                                                   30.375 ft.


mean draught 32 ft. takes the cake and prize. Her upper deck was removed during a major refit.


Waratah's twin quadruple expansion engines were under powered for her size. I have put together a few examples (from many) of twin engine (screw) steamers of the era:

SS Waratah, built 1908

gross tonnage      9339
length                  465 ft.
beam                   59.45 ft.

SS Omrah, built 1899

gross tonnage     8130 
length                 490.5 ft. 
beam                   57 ft.
power                  9 000 ihp
speed                   17 knots

RMS Morea, built 1908

gross tonnage       10890
length                    540 ft.
beam                     61.2 ft.
power                    13 000 ihp
speed                     16 knots


SS Indarra, built 1912

gross tonnage        9735
length                    450 ft.
beam                     60 ft.
power                    8 132 ihp
speed                     16 knots


SS Assaye, built 1899

gross tonnage        7396
length                    450 ft.
beam                     54.25 ft.
power                    6 500 ihp
speed                     16 knots


SS Devanha, built 1905

gross tonnage         8092
length                     470 ft.
beam                       56 ft.
power                     8 000 ihp
speed                      15.5 knots


To put this important issue into perspective, let's take a closer look at the famous RMS Baltic:


Tonnage:23,876 GT
Length:729 ft (222.7 m)
Beam:75.6 ft (23.1 m)
Propulsion:Two four-cylinder quadruple expansion engines powering two propellers.
Speed:16 knots (30 km/h; 18 mph)
Capacity:2,875 people

At the time of launch Baltic was the largest steamer afloat (until 1905). On her maiden voyage, she completed the distance between Liverpool and New York (2871 n miles) in 7 days and 13 hours, which matched her registered speed of 16 knots. Despite the excellent crossing time, Baltic was proven to be under powered, her twin quadruple expansion engines being the same capacity as her smaller siblings, Celtic, Cedric and Adriatic. Power output was 14 000 ihp, but for her size, should have been 16 000 ihp. Modifications were made at a later stage to improve the output. It is important to note that being under powered did not affect speed under normal conditions. However, in heavy seas, an under powered steamer would have had difficulty maintaining speed / heading = unsafe. Manoeuvrability would also have been compromised, catastrophic if the vessel was caught broad side in a fierce gale. 

If one uses the Baltic as a frame of reference the Waratah should at the very least have had a power output of 6 226 ihp, not 5 400 ihp.

This casts an intriguing light on circumstances off the Wild Coast, 27 July. The falling barometer and physical signs presaging the approach of a cold front storm of 'exceptional violence' would have alerted Captain Ilbery to potential problems. Waratah was heavily laden and under powered. A decision might have been taken to come about irrespective of whether there was a fire on board or not. Captain Bruce remarked that Waratah was smoking fiercely, which might very well have been due to a fire, but also a sign (excessive, dark smoke from funnel) that the engines of the Waratah were being 'pressed' to outrun the approaching storm. It was mentioned at the Inquiry that 15 additional tons of coal were consumed daily on the final voyage, partly due to 'pressing' under powered engines. 

There might not have been a fire at all !

Mr Grigg summed up Waratah's limitations to perfection:

The Waratah, he said; lurched very badly, 
and in an unusual way, and would breast 
the waves in a wriggling, zigzag manner, 
giving the passengers some misgivings
concerning her.

HOAX.

The Advertiser (Adelaide) Saturday 5 February, 1910.

THE WARATAH.
MESSAGE FROM THE SEA.
IS IT A HOAX?
Melbourne, February 4.
While walking along the beach two miles
from Prospect Reserve, Sale, this after-
noon Mr. J. W. MacLachlan. M.L.A.,
picked up a bottle containing the following 
message, which is undated:-

''Thrown overboard while the steamer Waratah is
sinking fast. Latitude 48 east (the "eight" is not very clear), 
longitude L 30 south.- J. Milburn."

(Harlow coordinates: 31 deg. 38 min. south and longitude
29 deg. 55 min. east.)
The bottle was a large-sized beer bottle,
and the message is written on thin white
writing paper. It was folded once, and
the edges were torn and discolored. The
message was written in lead pencil, and the
writing is fine and clear. The locality indicated 
by this message would place the
missing ship about 600 miles south-west of
Victoria. The lists of those on board
which have been published from time to
time do not disclose the name J. Milburn.
There was a W. Milburn on board, but
he landed at Durban.


Most of the hoax bottle messages were signed names with no connection to the Waratah. In this case a Mr. William Milburn was on board and landed at Durban, as reported:


The passengers on the Waratah included Messrs. HaroldGrigg and William Milburn, who till recently resided at Long Gully. They are both young men, and left for South Africa. Milburn played with the California football team early in the present season, and Grigg acted as one of the trainers.


The message was not dated and if one plots the coordinates on Google Earth we get:






The coordinates are interesting in that the marker roughly indicates a position en-route from Adelaide to Durban. If one is suspicious of the comment that the number 'eight' was difficult to make out, what would the lowest figure 'zero' give us?






Closer still to Durban and the final moments.

Perhaps someone on board during the passage across to Durban used Milburn's name and wrote the message? Whoever wrote the message might have thought it a lark at the time, but ironically might have remained on board beyond Durban. There was nothing amusing about the fate of the Waratah and her 211 souls, exacerbated by a complete absence of concrete facts as to why, where and when. Bottle messages such as this had a particularly cruel barb and there appears to have been a craze throwing bottle messages into the sea during the early 1900's. Tragedies at sea were sometimes regarded in the press as 'thrilling'. Present day commentators are careful to report tragedies with delicately selected words of sensitivity, but the graphic visual details played out over and over on TV are not very different and remind us of the dark side of humankind's fascination with tragedy - as long as it is someone else's misfortune.
