Can you explain more about bagging being faster than infusion? In what
little I have done (testing) it seems like the thing that takes the
longest time is to get the bag taped down and sealed well. The thing I
like about the infusion is that it does both sides at once. I was
figuring on infusing multiple panels under the same vac bag, just one
at a time by having a shutoff valve going to each panel.

You have seen my plans. My boat is smaller, but more complicated, I
expect. Would you estimate the time for you to build mine as roughly
the same as Solitarry? It sounds like you are estimating about 500
hours?
This really got brought to mind when I got the estimate back from
China. Assuming that materials cost him the same as me, and that the
Chinese workers get $20/hr (including profit and overhead), his
estimate looks to be about 2000 hours. If I have to double or triple
that, then I am looking at a project too big for me. I would really
like to know if I am looking at 500 hours or 5000 hours.
