Argonaut CAD Design

The original CAD designs are by Brent Hartwig who drew these up for us based on the above photos of Argonaut Jr.
 

Imagine for a moment what Simon Lake would think if he knew that Brent produced these 3D renderings in the woods of Idaho and sent them to interested people around the world in one evening.  No such tools existed for Simon Lake and would not exist until after man walked on the moon.

With a beam of 54 inches the submerged displacement volume, and thus the total dry boat weight.

Mass = 15980 pounds, which is just over 7 long tons
Volume = 44,2330 cubic inches, 256 cubic feet

Surface area = 62230 sq inches, 432 sq feet.

Center of mass: ( inches )
X = -0.1082
Y = 29.8981
Z = 0.0033

I expect the boat would need to be a bit heavier than this since it needed to be a bit heavy when submerged in order to stick to the bottom crawling along.  --Brent
