Analysis of information sources in references of the Wikipedia article "Archer-class patrol vessel" in English language version.
An interesting quirk of the Archer class is that although the regular crew have their own cabins, the midshipmen sleep in the gun-room. Traditionally this is where midshipmen have always been berthed but in the Archer class it is literally true as they sleep in the magazine of the Archer class. Since such trips only occur in times of peace, the gun which an Archer class vessel is capable of carrying is not fitted and so there is no other use for the magazine.

I can confirm that Ministerial approval for the change in name from 1st Patrol Boat Squadron to Coastal Forces Squadron was given on 21 May 2020.
