I'm no instructor, but I can teach you the basics of safety no problems.
Give me a shout when you get your kit, and I'll teach you the basic capsize drills; and a simple Eskimo roll (if I can still do it myself that is).
A helmet and buoyancy aid will be required. I'll be able to borrow a kayak and there's some great places along the Wye to have a play.
I like the weather to be hot mind!
