We all should do some math from time to time...

This is scary, an interesting study, and in the “whoops — we did exactly the wrong thing, and killed the economy” department...

Webb Chilesgets down to some basic math and comes up with the number 750 strokes to get 1/2 gallon of water using a manual watermaker. I'm sure this is an important number for Webb's next voyage. Truth be told, I found his figuring to be more than a little helpful in focusing on some math I'm working on as well.

Something a lot of people often forget is boats become finite systems once they get out of sight of land and, if you were to point your boat at Europe or Tahiti, you're pretty much on your own till you get where you're going.

Of course, since we all live on a finite system called Earth, you'd think that we'd all understand the concept of finite systems and sustainability but I'm often surprised how few people actually do...

It's pretty depressing when you think about it.

It would be a good thing if more people were thinking about the whole sustainable living/sailing on sailboats gig and doing the math.

Maybe some folks need an enticement?

As it happens, I have a copy of the most excellent DVD "Ice Blink" that needs a home. So, how about we have a little contest for some out of the box thinking on how to make a sailboat more sustainable and the most interesting thought we get before the end of May gets a brand spanking new copy of "Ice Blink"?

Let's see what you got...

Listening to Cream

So it goes...
