[76mmGuns]

As for the 57mm is oversized. maybe.. The US just disabled a container ship with 5 rounds of 127mm..

I was wondering if the 5 inch gun had working in disabling it. I could only find info that shots had been fired, not that the engine was disabled.
Chuck Hill's US Coast Guard blog has posted that 57mm guns aren't likely big enough to stop cargo ships.

There was a reason for the initial plan to buy 12 Arafuras; and anybody who has been, say, off Ashmore Reef in a Fremantle or an Armidale with the trades or the monsoon blowing knows what it was. Close in shore, light weight patrol vessels are fine but once you’re well off shore you want a sea kindly hull with a good grip on the water; and that can maintain better than 15 knots or so in SS4.

As an example.

How often does the RAN check the fisheries off Heard and MacDonald Islands?

it’s going to be a lot cheaper to send an OPV for an all expenses paid holiday then it would to send a frigate.
