Mate, have you ever known me to be frivolous on this chatline:~) Hmmmmmmmmmmmmmmm was i serious......Hmmmmmmmmmmmmmmmmmmmmm yup:~) Thanks for the thought "Build your kayak in peace" good sentiment. re "some bum you paid" I can see what you're saying but one does what one can and then uses offsets as an essential last resort and to provide opportunities for other people to do their bit. Everyone has stuff they pay others to do. Thank God people even pay me from time to time! Thats what trade and opportunity are all about.

Peter, you're right I did change the question because sure enough as Dave said the problem was a "monstrous imponderable" and no lifecycle analysts on the horizon. So I went to a gross approximation. besides my first post was a bit garbled after a very late night. Sorry! Your approximations sound much more realistic than mine thanks, gives me a much better shot at the question.

Dave, Re cellulose fibre - well I've still got my old Klepper! Anyway good points and they give me options for best and worst cases. Worst case is the Viking funeral. Best case is where a superb wooden boat eventually finds its way after several lifetimes of adventure into a museum. I certainly hope Tony's boats get there. You've demonstrated there's a good chance that most of the energy cost of building a boat has little to do with the chemistry of the materials and much more to do with infrastructure and transport. Hopefully your's and Peter's information and the method of subtracting out profit margins and labour cost along the value chain will give me a good approximation. I'll do the sums on that basis - but not tonight! Shame about the viking funeral though!
