class vessels. Originally
three ferries had been planned, but increasing demand called for
another to built & she was launched four years after her sisters.
is different to the
other three. As constructed, she had the
traditional open ended bow & stern decks, a feature that was added
to the other three ferries after refits. She is also the only one of
the four big ferries that continued the South Steyne's
ocean cruising, though there hasn't been a cruise in some years.
Another difference lies in her engines, which are very diffent to the
other three & deliver less power. The difference in the way this
ferry operates is enough that she has her own crew that cannot be
interchanged with her sister vessels. Collaroy
as built, had other
differences too that were designed into her for her proposed use as an
ocean cruising vessel - underwater stabilisers and a galley and bar.
The propulsion and control systems on the vessels Freshwater
are almost identical, but
utilises a propulsion control system which is unique within the
class. All four
vessels have two main engines which can be
used alone or, in conjunction, to drive one or both propellers,
depending on the mode selected.

was herself involved
in two of these accidents, the first
happened when she collided with Number 3 Wharf, Circular Quay on
the morning of Friday, March 4th, 2005 when she struck the safety
backboards. There was little damage to the Collaroy
but the backboards
were extensively damaged. The collision
occurred when the Collaroy
failed to respond to the master’s controls
and a number of back-up features also failed. One of
four control units, upon which he was relying to convert his
instructions into an altered pitch setting on the No.1 propeller, was
rendered inoperative by a faulty electrical circuit in a logic card.
The failure of warning and back-up systems, which should have been
activated when the control unit failed, was a consequence of human
error. These ‘defences’ were dependent on all four control units being
switched on at the time and they were not.
At 1:16pm on Monday 19 September 2005, the Collaroy
was on approach to
its berth at No.3 West Wharf at Circular Quay when it deviated from its
course and struck the northern end of the pontoon at No.2 Wharf. The
was not severely
damaged but the pontoon and its roof
sustained significant damage. The
collision occurred when Collaroy
did not respond to the Master’s
initial propulsion control instructions and a number of back-up and
recovery measures either failed or were ineffective. The collision was
initiated when an electronic component in the vessel’s propulsion
control system malfunctioned for about 35 seconds,
rendering both the primary and back-up propulsion control systems
inoperable from Collaroy’s
bridge. Approximately three minutes elapsed
between the onset of the failure and the collision, during which time
the Master was unable to regain propulsion control. The Master’s
actions to regain control were limited by his mis- interpretation of
the nature of the malfunction and his lack of familiarity with an
important procedure that would have allowed him to revert to another
form of control that was not affected by the malfunction.
As a result of the accident, Collaroy
was withdrawn from service for
In all, Collaroy
had fifteen collisions in
the period 2001 to 2005,
twice as many as any of her running mates.
Most recently the vessel broke down on the 18th of January 2011 and had
to drop anchor in Manly Cove until the problem was sorted out.

sudden influx of armed soldiers not to be alarmed!
