If you want to PM me i'll give you the number of the guy who owns Bantry Airport, he's a good guy and he might be able top point you in the direction of someone that will take you for a spin. Instead of hiring something which is a bit boring when your on your own.
If you are sailing to Kinsale then let me know, i'm leaving the Severn for Kinsale on the 25th of July with my uncle!
