Well you'll have a long wait to find out Mike - Ben's just put it off for a few years
Pity really - I would have liked to see a nice garden set up.

I think 2-3 years would be enough. I think it's better then my last long-term project, it will get me out and about more. (PM me for details. As it wouldn't be appropriate for this thread.)
Hey Mike, my goal is for my kids to leave home, get a job, get a house.
Unlike Ben, they have absolutely no plans to oblige me....... ever 
Hey Ben - build the boat mate and worry about sourcing the expensive
items later on - 'If you build it; they will come' 
Dave
hmm... the thing is, is that the prime-mover, the thruster and the hull its self, are the expensive parts. If I buy them first, then the rest of the ship will just sail along very nicely.
I left home, got a job, got a house, got a wife. Failed...miserably.
I got another house, got another wife. Failed...miserably.
I got a flat...didn't bother with a wife. Success...
Wish you all the luck in the world, I'm not going to bother with a wife. Being me is enough to deal with.

I guess I will come back to these forums in 2-3 years time.
