The patrol boat role has been part of the RAN for good reasons despite the obvious disconnect between sea police and warfighting. It provides an excellent means to train and identify commanding officers of frigates and destroyers. The boats are also useful in warfighting in our region as port/coastal defence and interdiction against local shipping.
Agree, ive done Majors and the best COs ive seen have done small boat CO time, not gone straight to major XO then CO, which is the alternative career path.
Junior officers learn ship handling and are entrusted more and more via their own watches leading to Limited Watchingkeeping Certificate before Fleet board.
The other distinction is for certain positions ACPB work is a world away from Majors. Here you are required to be more capable, and have a better knowledge and understanding of your job then on say a frigate where theres 5-8 in your department you can slack off and rely on. The work load can be more at times, and less in others but having the confidence to do your job makes it easier to be identified for promotion and creates a better sailor.
The ACPB world is miles away from FBE, and the experiences sailors and officers get here, makes them better if they choose to return to Major fleet, personnally i dont know why you would but hey thats me.
I was hedging more along the lines with t68. Turn patrol boats purely into a Customs/BPC role. Turn hydrography civilian and create a 2000ton corvette class (SEA1180) putting combat back into smaller sized vessels. The distinction here is combat. Not just shooting your .50 off the side but opponents who fire back. Keep the RAN warfighters and not ferrying about immigrants. Customs should be dealing with migration issues not a Defence force.
We would lose a 1/3 of our budget, even if the ACPB fleet costs 1/20th we would lose 1/3, as it would be seen by Govt. as Customs require the funding to protect our borders, while Navy are for foreign missions.
Hydro provide a good link between the fleet and the navigation aspect, losing that would lose a lot of experience and make it harder to get people into certain billets ashore that provide a specialist knowledge.
If we want OCV then that would be an inbetween of a PB and Frigate, not a replacement entirely. OPV is required because the job has changed, and customs right now are at breaking point as much as we are. If it was not for ACV Triton and Ocean Protector, then i guarantee they would refuse to do the job, which they can do as most are contractors. Its extremly hard to conduct SAR and bring 100+ onboard a ACPB let alone the Bay class. The Capes are still a long way from mission capable, and will take time to work out the bugs as many experienced members here have mentioned.
The Cape may be an improvement over ACPB, but the Armidales flaws only showed after they increased the workload, reduced the maintanence and spent more time at sea then what was intended. When that happens to Capes we shall see how good they really are.
