One of the key elements in the Canadian Navy's Boarding Party setup is that they're capable of being a prize crew.
Meaning that the NBP has members of all elements required in order to sail a ship, from a BWK to electricians, to stokers, CSE types, Bosun's, etc.
If we were to replace that with a seperate boarding party element, we'd lose that capability.
Doesn't it take a lot of time, and a lot of money to train
a BWK to electricians, to stokers, CSE types, Bosun's, etc.
? Aren't these the same trades you are having trouble recruiting and retaining?
Why would you choose to fill rubber boats in rough seas with these people so that other people can use them for target practice?
Cavalier as this may seem it would seem wise to me to fill those boats with folks that are more readily available and limit the number of SMEs that you have to expose until the vessel is secured. Once the vessel is secured then you can put your prize crew on board in relative security.
Why can't folks that are still new to the service and finding their way around be assigned husbandry and logistics tasks, and also receive damage control and hazmat training, as well as some CQB training? I have to believe that all sailors are trained to handle deck duties before they go to sea.
From what you, and Ex-Dragoon and others have said there is still a lot of brawn necessary in the modern navy.
As to bunks on the CPFs: I take your point. They weren't designed to accomodate an independent boarding party. For that matter they seem to be doing lots of things they weren't "designed" explicitly for. However much of the discussion about new vessels like the JSS and even the Ice-Breaker/Patrol Vessels seems to indicate a tendency to larger vessels with smaller "technical" crews. (59 ship handlers on the 6000 tonne Svalbard). Most of the modern OPVs are being built big enough to land a Merlin but only have crews of 30 to 50. Space on them doesn't seem to be a problem, in fact many of them include provision for "passengers".
Perhaps a larger complement of OS/Door Kickers should be considered in planning for the CPF/DDH replacements.
Note one thing. I am at least not arguing for a reduction in crew size.

I am arguing whether or not there is a case for a separate NBP entity or whether there is a case for additional bodies with specialized NBP training.
Cheers, all.
And Ex-Dragoon - I've "taken on board" ('pologies for the pun) what you have said previously about the need for extra SMEs to handle prize crews and to supply technical assistance to the NBPs. But the army doesn't tend to send Svc Bn WOs, Eng Sgts and Sigs Ops to assault enemy positions on their own.
