I was so sorry to hear this news. It is interesting that the image that Timmo has posted was the very first thing that went through my mind. I think it was the 2012 Thames raid when this craft first took to the water in this form. As I recall, it did not track too well in a straight line and turned on command even less well. The man and his boats will be missed by all who knew them.
He was one of those guys who you think of a just an eccentric but the more you talked to him the more you discovered how much he knew and how much he had done.
This picture was taken at Stalham...
I've missed him over the last couple of years at Beale.
He could always be trusted to bring a smile to your face. He took pity on me more than once preparing my pot noodles, and knocked up a gourmet meal from his vast store of tinned potatoes and corned beef, whilst we chatted over "Elf n Safety" and the like.
