I've pondered the air vs. water prop and it seems that the disadvantage of an air prop is travelling upwind at which point you'd need higher revolutions to achieve the same through-the-water speed. We generally don't deal with water currents on the lake so it wouldn't be a factor with a water prop. Either way, some very interesting craft have been built as evidenced on that site.

Thanks M&M

Thanks to the Webmaster for recategorizing this thread. I didn't want to post original in the webcam thread but it was the only way to reach the original target.
