Thanks for the replies.
Must say that I havent suffered this before (bikes, Kingairs etc), but my research has noted that its a common problem with canoeists (scuse spelling). Is it a problem with the seat, the angle of our legs(feet not on rudders really) or is it a problem with me/us.Im tall. What about circulation in the pressurised enviroment(DVT). To be honest its normally only one buttock that goes numb or goes numb first followed by the other a while later.
Thanks.
Maybe there is a 777 with a seat for me or a 380 so i can go for a jog.
