Thank you very much.

Sure, but I've only followed Leonardo's instructions....
AFAIK this boat with paddles was never built, it appears in
the "Windsor folios", though there is another version more
complex (mechanically talking) in the "Codex Atlanticus".
Leonardo had great ideas but the only energy he could
count with was human strength so I suppose all these
machines (including flying ones) failed in their purpose.
But, as with other machines, it's amazing to see something
that was thought in XV century and that look so modern.
A good mix if old & new technology, I believe.
Bye.
