Doc I know that Portland are regularly tasked directly by Portland CG, which is one reason Chiv gets so few jobs in S Devon which is, as far as the ARCCK are concerned, Chivenors patch. There will always be overlap of SAR boundaries and Portland are often tasked to Burnham or Weston if Chiv is on another job or the wind favours Portland.
Just last night I did a job in Culdrose's patch because we were airborne when the job came in so the response time was quicker - that is how the ARCCK works but only if they get told about the job first - if a CG launches their own helo first and then tells the ARCCK, then it is not a surprise that Portland get more jobs.
It is difficult to know just how the jobs share goes with the CG flts because we don't have visibility of their call outs.
As for 189 - this is a rumour network after all
There still won't be enough room in the cabin for an ECMO incubator though
