Well only having two Armidales in the water when a couple of months back was quite concerning. I too have seen the Bay and Armidales in the last couple of mouths. It was apparent to everyone that even basic ship keeping on the Armidales isn't being maintained. While the Bay crews are "posted" to the boats for much longer they don't live with them like the Armidale crews do.
The Bay's have been to Cocos but I agree that the Armidales have been flogged a lot harder.
For me I'd just like to see the RAN own up and admit that they've caused their own issue. Binning your naval engineers, flogging your vessels outside of spec, then blaming DMS and Austal for the ship availability isn't going to solve the problem.
Skippers have some level of responsibility for letting basic ship keeping skills slide.
A few things which keep coming to mind any time people start getting into some of the problems the
Armidale-class patrol boats have been having.
One of the first, and possibly the most crucial, was who/what decision-making authority decided to have SEA 1444 follow an acquisition programme different from defence norms, in that instead of the RAN/Defence deciding the number of vessels required, the manufacturer did, as well as provide 15 years of maintenance and support. Relating to that, is who/where was the decision made about the sea conditions that the ACPB's would be operating in?
The ACPB is supposed to be able to conduct all ops in conditions up to the top end of Sea State 4, with the ability to conduct surveillance ops in Sea State 5. From other reading it is suggested (but not confirmed) that the ACPB is designed to be survivable in conditions up to Sea State 9. I readily admit I have my doubts about that one...
Realistically though, how often have the ACPB's been required to operate beyond Sea State 4? And along those same lines, how often have the
Bay-class ACV's been called upon to operate past design parameters?
From my reading of the programme specs, it was expected that the ACPB's would provide 1,800 ship-days for BPC functions p.a. and that Austal anticipated that 12 vessels would suffice to meet that and a 3,000 ship-day p.a. service life, for 15 years. What is the realistic Sea State that the
Bay-class operates in, and what is the service expectation from both the
Bay-class and upcoming
Cape-class ACV fleets?
I suppose what I am getting at, is that the RAN seems to have service requirements which really require an OPV-type vessel, instead of something designed for Sea State 4. If due to Gov't involvement, the programme was tailored for a Sea State 4 vessel, but Gov't still had higher expectations from the RAN...
Similarly with respect to maintenance. With having three crews for every two vessels, how much time is allotted for routine maintenance, when something is not broken or about to break? Looking at the original programme service requirement, the original 12 patrol boat fleet would need to spend ~68% of the time at sea, in order to meet the ship-day requirements. Given that generally three of a piece of kit are required to maintain a constant presence, with the other two either in maintenance, or in a training/workup/return cycle, getting double that amount of service seems... ambitious.
Also, what is the division between what RAN personnel can/are allowed to maintain, and what is the manufacturer's responsibility? The fact that the programme is outside the norm for how Defence conducts and acquisition, as well as the apparent tendency for Defence/Gov't to ship mainenance to private contractors for "cost savings" makes me think that Gov't would prefer that Navy be the end-users, without the responsibility or capability to maintain vessels. If that is the case, then that is short-sighted, since if Navy (or anywhere else in Defence) needs something fixed immediately, particularly in dangerous and/or remote conditions, private contractors need to be brought in, which will cost extra, if they can be induced to go, etc.

EDIT: Looking at the Customs Factsheet for the
Bay-class ACV, it mentions an "annual fleet target of 2,400 patrol days". I find that curious, since that would require the fleet to be patrolling over 80% of the time. Other things I find curious is that the
Bay-class, which first entered service in early 1999 was originally expected to be replaced in 2010. Another would be that the ACPB is is ~18 m longer than the
Bay-class it is based off of, yet only displace ~40 additional tons.
Additionally, when I mentioned maintenance, I was speaking of the Austal/DMS tender.
