Thanks for the heads-up on the tent peg. I contacted James at the Swanage campsite but it appears that there are actually a number of tent pegs left there - each engraved with the name 'M. Demuth' (obviously they belong to some sort of tight arse).
I think if you take a look at the Performance Sea Kayak rules page - UK Circumnavigations - Para. 9f. Sub-paras 93 c(+d) you will find that ' The timing for any record attempt will not be complete until any and all equipment involved has been fully accounted for'
I think to that end your 80 day record is probably nearer 750 (at the time of writing) - oops!
