I have a small leak on my Humber Rib. I put a small patch on to see me to the end of the season. I thought I would put seat patches on in order to protect the tubes further. I need about 10 however they seem to be in the region of 10 each which to be honest makes it an expensive exercise. Any suggestions on where I can find cheaper? I used to have a friend in Hypalon business but sadly no longer. Also need a couple of rope anchor patches.
