I have been following this thread since the beginning as I was genuinely saddened to hear of the loss of R116. Condolences to all involved.
I have the utmost respect for the SAR community, these guys do fantastic work.
Here is more info on the fisherman's injury. The decision to launch is not made by the IRCG but by medical staff at Cork University Hospital based on the information given to them. Doctors will generally err on the side of caution if they are to be held responsible. The accuracy of the information they receive from the fishing boat is another factor. It seems the helicopter crews don't have much of a say in the decision.
Miscommunication over severity of fisherman's injury responsible for last journey of R116
