Ah not that sort of sailing, this is the sort that includes sails and spending lots of money rather than making money! Shore based job now.
Dunlop K70 do the right sizes and I don’t think they are fussy if they are front or rear so think that is where I will end up.
Sent you a link to a tank I saw on ebay last week Eddie, it was a Hotmail address so not sure if that is still in use. Also I was looking for those photos you sent of your frame where the footpegs attach, as mine had been cut off. Might have to ask you to send again if I cannot find them!
Enjoy UK, have a beer or two for me.
