yup...I expect it to take a year or more before it goes into the water...perhaps years more before it's complete.
No reason I can't continue to work on it when it's in the water is there?

As long as you fix any holes in the bottom, first......... - you should be fine.

no holes in the hull discovered so far. Not counting the transom. I very much doubt that there are any. Harvey left us a present...about three foot of rain. When I checked on the boat after the rain...it had more than six inches of water in the bottom where i'd removed the foam.

It was NOT draining out.

I figure that if it can keep water in...it can keep water out.

I'm not gonna even google transom - I'm sure it's important.

Thar's a logic in them thar thoughts.

I wouldn't bet my last dollar on the logic being correct though...

Even an ill wind blows some good, it seems. Perhaps having a solar powered boat is less wacko than it might have seemed before you got Moses' flood dropped on ya.

... and I think you can look forward to conducting various tests of a multitude of design ideas. I sure hope I can look forward to your posts about them =)

Edit: errr, I suspect I meant Noah. =p

I'll blog about them.
feedback is appreciated.

I am excited at the prospect. There's little I enjoy more than tinkering and testing, and then enjoying the fruits of experiment.

Balaklava may be the only thing.

but wait..! There's MORE...I just discovered AIR-CRETE!!

Concrete made with vermiculite? Not very heavy, which is why it's useful. Ballast may not be one of it's most applicable uses.
