The world's last surviving wooden whaling vessel, the Charles W. Morgan, is being restored to sea-worthy condition again.

The above image is taken from a laser scanning system being used to map weak points and provide a detailed 3D reference model of the vessel.

Seems doable... check out the Mad Mariner™ test.

I am impressed it handled being walked on, even if it was a child :-)

Thanks very much to Fred, who did my work for me and found a more detailed link about the previous Vertical Axis propellers. These drives are becoming more common on various workboats where maneuverability is key (fireboats, tugs, etc.)

Well, not really a propeller, but a mechanical "flipper" being studied by some MIT students. Check the film: read more »
