An ideal opportunity to learn to cast with your other hand !!!
I hurt my right wrist last year and it was giving me a fair bit of gip after just a few i minutes casting. So to give it a rest I started trying to cast with my left hand. It felt really wierd for the first few hours and resulted in a few more tangles than normal but then it began to get easier. Now I can cast to a naff standard with both hands
:
But it's really useful and safer when the winds against your normal casting shoulder, or you're in a boat with a fishing partner.
My one recommendation if anyone wants to try it, is to start off with a shortish leader and a single fly - this will minimise your tangles until you begin to get the hang of it.
