Cool achievement guys. I'd love to go round Anglesey in a boat (and all along that coastline, having looked at Puffin Island and Great Orme out of my window for the best part of 4 years when I lived up on the hillside at Llanfairfechan). Maybe we'll re-engine Blue Ice and come up and have a go at beating your record!
P.S. More details including the rules for this new record and contact information needed by those who would like to have a go at breaking Ian & Dave's record (but please leave it a little while so they can enjoy their success!) can be found in the forthcoming issue of BIBOA's club magazine Riblines, which should be dropping through letterboxes in the next few days.
