I checked the story of the Iron Baron on CTX and the Australian weblink
and added some info as attachement that you can find useful. By chance I
had an old exemplar of the BA chart 167 and I copied the pilot area.
The report gave the feeling that the Iron Baron had a pitch propeller,
which is strange for such a large vessel.
It would explain a lot because pitch propellers are very bad for maneuvring,
for sure when the propeller is stopped or turning slowly
as it does not send enough water to the rudder.
Furthermore they are not so good to swing the ship
as the astern effect is opposite to the forward one.
But by reading carefully I believe that the words "increasing the pitch" simply mean
increasing the RPM.
It seems also obvious that the master had the wrong distance from the Hebe
reef light tower, and that was likely the most important contributing factor.
The NW wind appears also to have prevented the ship to swing quickly to
port, as it implied to bring the higher stern against the wind.
At 1935 when the pilot was on the bridge, you can see on the BA chart that
the bow of the ship was less than 2 cables from the shoal water, too short
to swing safely to port and clear of the shoal. There was more water on
starboard side and the pilot had it right to bring the ship to this
direction, but it had to cancel the swing to port first, and that took too
much time. Perhaps a full astern maneuver could have been more successful,
but there was the inertia and the current.
I believe that a possible mistake of the pilotage was not to have instructed
the master to put the ladder on starboard side, steer a safe North Easterly
course until the pilot was on board, then he could make a broad full turn to
port to come in line with the leading lights somewhere NW of Hebe reef. More
or less like the Aegean Sea should have done, but on the other starboard side.
