The official line is that only rarely do modern cargo ships get in trouble in The Rip.
That's partly because of the greater power on tap, the expertise of pilots, dredged channels, and the better data (i.e the time of slack water).
Here's a quote from the Port Phillip Sea Pilot service
"The Rip is still a very dangerous area for all craft because of the strong tidal flow and the uneven nature of the sea bed
and is at its worst when a full ebb tide of up to 10 knots meets a southerly gale. This and the fact that slack water
is three hours after high and low water
explains why so many ships were wrecked there in the early days. The ship's captain
timing his arrival for low water and expecting to get the first of the flood tide through the entrance found that he was caught in the strongest part of the ebb tide, and in trying to enter could be swept on to Point Nepean.
"Ships have changed considerably during the history
of this service
, from sail to steam, powered by coal or oil
fires, but today nearly all have diesel
engines, some up to 40,000 horsepower. Speed and reliability
have increased dramatically, some can do in excess of 25 knots but the average would be about 15, so it is rare for a ship to be held up by the tide at the Rip."(from History - Welcome to Port Phillip Sea Pilots website)
