At Gowlane, I spotted the commemorative plaque. Some web searches indicated that the stone was erected to commemorate kite-surfer, Fintan Hoare, who died while surfing off Banna.
The fact that it did not include a surname did give it a sense of being more personal.
The location of the stone is definitely such as to tempt one to sit and reflect while taking in the view. It did what it was intended to do.
