Michael,
Rolf is an ex Tornado sailor and would be a better source of information regarding your obligations should you decide to build a Tornado.

Regarding the costing of your project:-
I had not considered that you would waste any money.
I was just asking about the budgetting for essential materials.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
